<hr />
<div>This is a learning experience to use an Arduino to make a version of the Theremin. The Theremin is a musical instrument that is played just by putting your hands near the instrument:<br />
<br />
*[http://en.wikipedia.org/wiki/Theremin Theremin From Wikipedia, the free encyclopedia]<br />
<br />
The Theremin normally uses radio waves to detect the position of the hands, we will use light falling on a photo resistor instead, and for now just to pitch and skip loudness.<br />
<br />
== Approach ==<br />
<br />
It is often good to do a project by breaking it down into steps and make sure that each step works before making the project more complicated. We will do this in two way. We will build the project up a step at a time, and we will when possible "steal" code from other projects and adapt it to ours.<br />
<br />
== Debugging/Logging Project ==<br />
<br />
It is nice to have a seral port to control a project and have the project report back to you. We have done this in a couple of projects. Lets steal the code from SerialSound2 and save it into a new project called SerialLog1. Modify the code so all it does is recieves the incomming character, add one to it and send it back. Let Mr. H check the code when you think this part is done.<br />
<br />
== Measure Light Brightness ==<br />
<br />
To start this stage in the project open SerialLog1 and save it as SerialBrightness1. Now in another project ( LDR ) we had a light dependent resistor and blinked some LED's depending on the brightness. Lets steal some of that code and add it to the current one SerialLog1. Modify the code so that when the light goes from on to off the Arduino sends "light off" and when it goes from off to on it sends "light on", and finally when the light does not change the Arduino sends nothing.<br />
<br />
A note on the light dependent circuit. You need to use a resistor in series with the light dependent resistor, this combination lets a variable current flow through the circuit. The voltage across the resistor will vary with the light brightness ( so will the voltage across the LDR, the two will total to 5 volts. ) What size resistor should you use? Put the LDR in medium brightness and mesure its resistance with a ohm meter. Use that value resistor then in medium light you will get 2.5 volts into the Arduino.<br />
<br />
Circuit:<br />
<br />
<br />
[[File:VdivideLDR.png]]<br />
<br />
Where <br />
<br />
Input = 5v from power supply Vcc<br />
Output = signal to connect to Arduino Input Pin<br />
<br />
Note that the LDR is is on the "high side" wo in the dark where its reisistance is high the ouput voltage will be low.<br />
<br />
<br />
Let Mr. H check the code when you think this part is done.<br />
<br />
== Measure Light Brightness Analog ==<br />
<br />
The last program just told if the light was "on" or "off". What we want to do is get an integer ( int ) that tell how bright the light is. This is a conversion from the analog ( continuous ) value to a digital approximation. To do this we use the Arduino's analog to digital converter ( adc ). Open the project SerialBrightness1 and save it as SerialBrightnessAnalog. Also open the sample project on analog to digital conversions Examples -> Analog -> AnalogInSerialOut. This has pretty much all the code you need, but as an excercise use it as a guide to modifying your program. Your program should output the brightness only when it changes.<br />

<div>Lots of external Arduino Links<br />
<br />
A very popular, AVR development board; uses the AVR so also see: [[AVR Links]] All the tools are free, you need the chip, a cable, and possibly a power supply. Software is free, chip programs via a bootloader, so no hardware programmer is needed ( unless you blow the bootloader ). May be the cheapest/easiest microcontroller for beginners. Popular with the technical artistic types ( googel DorkBot for more info on this type of person ). Most boards are set up to take plug in boards called "Shields" which add additional hardware to the base Arduino.<br />
<br />
Key words to help you search the table.<br />
<br />
*Projects: project descriptions, enough to reproduce the project, not just nice pictures<br />
*Links: a link to more links.<br />
*Info: Useful information that does not rise to a tutorial, misc. tips.<br />
*Forum: for a forum, mail list and their ilk.<br />
*Servo: for servo motors.<br />
*Stepper: for stepper motors.<br />
*Supply: for the boards and parts<br />
*Shield: this are add on boards for adding functionality.<br />
*Tutorial: a tutorial or how to.<br />
*WebRing: for a Web Ring.<br />
<br />
So, for example, if you are looking for projects then search on "Projects".<br />

[http://www.pjrc.com/teensy/teensyduino.html "How Does Teensy Compare With The Arduino Board?"]: the biggest difference is that Teensy uses direct native USB communication, so (a) Teensy communicates *much* faster than Arduino (12 MBit/sec vs 38.4 kbps), and (b) Teensy can be programmed to act like a USB mouse or a USB keyboard. [http://www.dorkbotpdx.org/blog/paul paul's blog] often talks about Teensy.

<div>Lots of external Arduino Links<br />
<br />
A very popular, AVR development board; uses the AVR so also see: [[AVR Links]] All the tools are free, you need the chip, a cable, and possibly a power supply. Software is free, chip programs via a bootloader, so no hardware programmer is needed ( unless you blow the bootloader ). May be the cheapest/easiest microcontroller for beginners. Popular with the technical artistic types ( googel DorkBot for more info on this type of person ). Most boards are set up to take plug in boards called "Shields" which add additional hardware to the base Arduino.<br />
<br />
Key words to help you search the table.<br />
<br />
*Projects: project descriptions, enough to reproduce the project, not just nice pictures<br />
*Links: a link to more links.<br />
*Info: Useful information that does not rise to a tutorial, misc. tips.<br />
*Forum: for a forum, mail list and their ilk.<br />
*Servo: for servo motors.<br />
*Stepper: for stepper motors.<br />
*Supply: for the boards and parts<br />
*Shield: this are add on boards for adding functionality.<br />
*Tutorial: a tutorial or how to.<br />
*WebRing: for a Web Ring.<br />

|The FEZ Domino is a Arduino-shield-compatible controller board. However, it does not have an Atmel processor -- instead, it has a 72Mhz 32-bit ARM processor with about 148KB Flash and about about 62KB available when programming it using Microsoft .NET Micro Framework. It includes both the standard Arduino "peripheral" USB socket to connect to a PC for reprogramming, and also a "host" USB socket to connect to a standard USB keyboard, mouse, joystick, etc. Also includes a slot for a micro SD card.

I have been thinking about how to get more traffic at open circuits. So far:<br />
<br />
*Post links to it on forums, these are usually on topic for the forum, not just ads.<br />
*Started a sub wiki for SourceBoost C ( much of which is just a collection of stuff I was doing here anyway ) If this seems to commercial, let me know and we can see if there is a better way to do it. I think it fits the site well however.<br />
*When I link to sites now I often send an email letting them know and inviting them to contribute, not too much has come of this yet, but more time will tell.<br />
<br />
*Should we consider adding the site to some web rings? If we think this is a good idea what process should we use to discuss and keep the process under control.<br />

== Take a look at..... ==<br />
[[russ_hensel_test]]<br />
<br />
take a look at a page I am working on for PIC projects ( all external )<br />
It clearly has a ways to go, but then I am planning to link it in somewhere public.<br />
<br />
The page is supposed to have a fairly clean look for browsing, and some structure for searching.<br />
<br />
I am still struggling with getting the formatting down right.<br />
Is there a test for what is open that we should be applying?<br />
<br />
Let me know your thoughts.<br />
<br />
russ_hensel<br />
<br />
: Looking good. Thank you. The "Editing help" link (just below the "Summary" bar that shows up after you start editing a page) *ought* to have tips on formatting. Maybe next month :-).<br />
: I made a few minor tweaks that I *thought* made it look better -- hit that "undo" button if I've only messed things up.<br />
: For [[open hardware]], I'm using the consensus definition at [http://en.wikipedia.org/wiki/open_source_hardware Wikipedia:open source hardware]. If they've posted the schematics and firmware online, and indicated that anyone can use the design information -- perhaps released under GPL, Creative Commons, or public domain -- then it's open hardware.<br />

== Armus board ==<br />
Hi!<br />
Very glad at least one guy did show some enthousiasm about the project!<br />
Currently, as the project was left (and will probably stay....):<br />
Hardware is all good. The board with gerbers can be sent to most major Fab House and you will receive a functionnal design. Proto1 was tested and around 5 glitches have been found and corrected for Proto2, wich was never tested but should be 100% functionnal.<br />
<br />
The Firmware of the 4 DSPics is symetrical, and is "complete". It interface to Servos and DCs. The input encoder, if I recall, is not done, but the code is there and all C, so it should be easy to just copy-paste a snippet from somewhere else into the project.<br />
The Firmware for the multi-IO PIC18 is complete, and you will be able to play with all IO.<br />
The Drivers to communicate to the PIC and DSPIC from the kernel is done and documented.<br />
Ah, yeah, we have drivers for Ethernet/CAN/Sound.<br />
We also have a complete compiled kernel ready to load onto the board with various "demonstration" mode.<br />
<br />
Most of the work left is polishing here and there, as the firmware/driver part was done is haste. Most of the things work 100%, and will need no touch, but some functions (like the Quadrature encoders) are plain missing.<br />
<br />
The part where more work is to be done is on the Integrated Devellopment Environment (IDE). Shure, you can use KDevellopp, Eclipse, or any cross compiler out there. You could even download some dev.boards' software and load it onto ARMUS and compile natively from there. We had in mind (read the article) to creat a simple and easy IDE for 1st year undergrads, so maybe it's not necessary for you :P<br />
<br />
If you want the =WHOLE= project CVS for you to enjoy, I have it and could send it to you trough FTP or any other way you prefer. I guess I could also just mail a DVD. It weights around 700MB, and there is ton of french comment and files (as the team, in Quebec, was native french) but I could translate any part you feel is critical for specific applications.<br />
<br />
If you want to work on this "on your own", most of the board is based on atmel's AT91RM9200EK and AT91RM9200DK . Their demonstration Kernels should run as-is with the same procedure as Atmel's.<br />
<br />
Just to say: what do you plan to use the board for?<br />

'''Wow.'''<br />
This is too cool to stick on a shelf a let it gather dust.<br />
I want to see projects like this "ratchet forward".<br />
I want to allow people to build off last year's work rather than starting all over again from scratch -- so in a few years we can finish amazingly cool projects that are far too complicated for one team to finish in a year.<br />
<br />
I think this [[ARMUS Embedded Linux Board]] might be perfect for a CNC machine.<br />
The LinuxCNC software runs on Linux, so it ought to run on this Linux board.<br />
And the DSPics should be able to drive the power transistors that run the motors on the CNC machine, and track the position of the routing head.<br />
<br />
And not just a single CNC machine -- a series of open-source CNC machine designs. Designs that anyone can build, improve, and then share those improvements with the next builder.<br />
<br />
Yes, please do send me the project files.<br />
These are all "public domain" or "[http://creativecommons.org/ creative commons]" or "open source", with no warranty, right?<br />
<br />
Do you think that perhaps http://SourceForge.net/ or [http://en.wikipedia.org/wiki/GNU_Savannah GNU Savannah] might be a more appropriate place to host this software than Opencircuits?<br />
<br />
Alas, I am embarrassed to admit that I barely speak 5 words of the lingua franca, the French language.<br />

Why don't you help finish my programmable chip eeg project and then use what you learned and the results to then create your own project. Programmers like to reuse working modulas instead of reinventing the wheel.<br />
<br />
The pceeg has gone through a major revision streamlining its design and I am working on the father board a digital computing board for the project. I will be cleaning up the page. <br />

<br>Thank you very much you create this wiki to let us to share electronic projects. <br />
<br>I want to merge the "[[RS232 Dev Board]]" and "[[RS232 RS485 USB Converter Board]]", so want to discuss to the author, Tkb, of "RS232 Dev Board". However, i cannot find out the talk page like i talk to you by this way. Can you point me how to do it?<br />

Hi David, great site!<br />
...<br />
<br />
----<br />
<br />
Aloha David,<br />
Roger here, I'm still puzzeled as to how to create a new article. I uploaded an image file for the 723 regulator (my article subject). This went into an "Image File page" automatically, OK. I added it to the Voltage Regulators section of Components/Integrated Circuits, OK. But I couldn't figure out how to make a document like there is for LT1528 OO. I put the info I have into the discussion page for the image, but that is only a temporary solution.<br />
<br />
How does one create a new article page that isn't a "talk" page for something else? Beside the info on the IC, I have a couple of documents that are in-depth on using the device. These should be near each other as well as near the info document above. How would I go about setting up a "723" sub-chapter of "Integrated Circuits"? I guess that's as clear as I can make the question.<br />
<br />
I would also like to suggest a modification to the linkage. I'm reading the synopsis on the LT1528, I want to find oout more, so I click on the image, but instead of taking me to an in-depth article, it takes me to the image file page. There I have to look at the Links to find the article (which is only identified as LT1528). I'd like to be taken to the article instead of the image. Take me to the image only if there is no article. Of course this may be more difficult to make happen--I don't know how the site is structured. My web programming is very basic. Still, I think this makes sense from a user's POV.<br />
<br />
Thanks in Advance,<br />
[[User:RogerAF|RAF]] 17:26, 22 May 2007 (PDT)<br />
<br />
Aloha, Roger.<br />
You're doing great.<br />
<br />
I agree that it would be nice if clicking on the picture of the LT1528 took you directly to the article about the LT1528.<br />
I don't know how to fix it.<br />
<br />
Do you see the "Help" link in the navigation bar on the left side of every page?<br />
I think the page it brings up needs a few more tips.<br />
But I want to keep it short and simple.<br />
If I explained every detail, it would become a bloated 100-page document that nobody would read.<br />
<br />
There are already far too many bloated 100-page documents about electronics.<br />
<br />
I hope that you, dear reader, and other volunteers will make Open Circuits into a place where people can learn to do amazing things.<br />
A place that avoids forcing people to learn 100 irrelevant details before learning the one thing they need to know before they get back to building their robot (or whatever).<br />
A place that never makes people throw away good ideas, because we never confuse people into believing that it would be far more complicated and expensive to build than it really is.<br />
<br />
p.s.:<br />
Picking the name of a page is a bit of an art.<br />
Since we want to refer to a page a lot, that's easier when the name is very short.<br />
People new to wiki always pick names that are too long, or have too many capital letters.<br />
Fortunately, it's very simple to rename pages.<br />
You rename pages by clicking on the incorrectly-named "Move this page" button.<br />
(I don't know how to fix that, either).<br />

=== making links ===<br />
<br />
Speaking of linkage, making links is one of the most important parts of this wiki.<br />
<br />
Whenever you find one article mentioning some other article, you can click on that word to get more detail.<br />
<br />
If that word is not already clickable (underlined and colored), please make it clickable.<br />
To make a word clickable, hit the "edit" button at the top of the page.<br />
Then add double brackets <nowiki>"[["</nowiki> and <nowiki>"]]"</nowiki> around that word.<br />
(Some people recommend only making the first mention of that word clickable).<br />
<br />
The cheatsheet ( http://en.wikipedia.org/wiki/Wikipedia:Cheatsheet ) calls this an "internal link".<br />
<br />
Here's the trick: you can add those brackets to any word, making it into a link.<br />
Some of those links will go to pages that don't exist yet.<br />
<br />
What happens when you click on one of those links to a page that doesn't exist yet?<br />
<br />
I'm not going to tell you what happens.<br />
Go find out for yourself.<br />
You can practice in the [[meta:Sandbox]].<br />

Aloha David,<br />
Roger again; I want to thank you for the info and hints. I'm catching on. I got my component description linked to the caption under the image on the Components/Voltage Regulators page. And I created a "New Article" which I then "moved" to the title of my article. And my article has a link to the description and that has a link to the article, so I'm getting the hang of it. I have several schematics and PC artwork images to upload and link to my article, plus a second article I want to publish (I didn't write it, but I've been unable to find it on the internet--I have a xeroxed copy from 1986 or so and that is the only existing one as far as I know). That article also has several images that go along with it. I wondered about the feasability of uploading a .pdf file (I made one of it) to this site. Would that work? Should I even try? I don't want to screw anything up, but wouldn't that be a lovely thing if we could upload .pdf files? Just a thought.<br />
<br />
Again, Thanks very much, I've made some progress.<br />
<br />
[[User:RogerAF|RAF]] 19:48, 23 May 2007 (PDT)<br />
<br />
Aloha, Roger.<br />
You are welcome.<br />
Have you tried creating a link to an article that doesn't exist yet, just to see what happens when you click on that link? For example, the [[switching regulator]] page that I'm going to start in a few days.<br />
<br />
I don't know about this article that you didn't write.<br />
If the original author wants people to post it widely, and doesn't mind us editing it, then great, let's post it (and give correct attribution).<br />
But some writers go a little crazy when they see that someone random stranger has copied their stuff and posted it to the internet.<br />
(That's why there's that "DO NOT SUBMIT COPYRIGHTED WORK WITHOUT PERMISSION!" note at the bottom of each Edit page).<br />
<br />
I wouldn't mind you posting a .pdf file (that you wrote) temporarily.<br />
It's better than nothing.<br />
But I would expect someone to eventually convert it to text-and-images.<br />
That makes it much easier for the next person to improve the it.<br />
<br />
Thank you again for adding useful information to Open Circuits.<br />
I hope you won't mind people "improving" the things you post here.<br />
<br />

Aloha David,<br />
Sorry for the delay, I had a loonng job and then our cable modem failed. At least they swapped us a new one free (hooray RoadRunner). But I want to explain the article: "The Many-Talented 723" by Glenn Prescott. I came across this as a xerox copy sometime around 1985. It was evidently published in a magazine for radio enthusiasts--there are some ads on the last page for radio gear. But the name of the magazine isn't on any of the pages. I Googled for the article and got no returns. I think it is a very good article as far as describing the IC and how to use it. It helped me when I was a beginner, so I want to share it. However, I don't want anyone to get into trouble over it. I just did another search on Google and all the returns refer to my mention of it here on Open Circuits. Like I said, this is a copy that I have, no clue as to the magazine that published it, no copyright date, no nothin'. But I will leave it to your judgement if it is a risk. I still have my own article to get uploaded along with images. I will concentrate on getting mine done before doing anything with the copied article.<br />
<br />
[[User:RogerAF|RAF]] 20:27, 26 May 2007 (PDT)<br />
<br />
Unless the author has given permission to publish it, I think a better idea would be to write your own article, citing the one you're talking about further details. Ideas are not copyright, but the expression of them (i.e. the text of the article) is, or so I understand. [[User:Autarch|Autarch]] 10:22, 13 June 2007 (PDT)<br />

== Baudline Free Software ==<br />
<br />
On the Open Circuits [[oscilloscope]] page,<br />
I don't understand why you took "baudline" out of the "open source" section.<br />
Anyone can buy the source code with a "GPL source code license" at<br />
http://www.baudline.com/source_code.html<br />
.<br />
You have read what our [[Main Page]] says about "Selling Free Software", right?<br />
GPL is open source, right?<br />
--[[User:DavidCary|DavidCary]] 03:16, 26 October 2009 (UTC)<br />
<br />
Sorry, I only read the license for the free download. Come to think of it, however, "The source code is expensive and it is intended for qualified corporate or institutional buyers" seems like a big deterrent to any hobbyist getting their hands on the source any time soon. While the software is technically GPL, it seems almost pointless to list it as such. I'm probably not going to modify it more than I've done though (listed it twice).<br />
<br />

: Alas, as [http://www.gnu.org/philosophy/free-software-for-freedom.html Richard M. Stallman pointed out], there seems to be confusion around the word "free".<br />
<br />
: Yes, "source code is expensive" is a big deterrent to hobbyists.<br />
: Perhaps putting things in the technically correct category is "pointless". But if so, why bother using a category if it's not useful to our readers?<br />
: The "PC Oscilloscopes" category looks even less useful, since (currently) it appears that every o'scope on entire the [[oscilloscope]] page seems to be in that category. (Is that just a formatting glitch?)<br />

:: * I too care more about libre than gratis.<br />
:: * I don't think I really put my finger on why it seemed wrongly categorized before but to me it's confusing to link to a piece of software's homepage, where the only downloadable version is non-free and say it is free software without reservation. The way it is now clears that up I think.<br />

<br />
=== General ===<br />
<br />
These guys have huge catalogs and an immense selection of parts, yet are still willing to sell things in onseies-and-twosies to hobbyists who can't claim to be prototyping something that'll sell a million units next year. Digi-Key actually got its start in the ham radio market, selling digital keyers.<br />
<br />
I ([[Wiml]]) find that Digi-Key is the place to go for digital stuff, microcontrollers, and the like. For discretes and analog parts, Mouser is usually cheaper and has a better selection. Neither company has a minimum order, but of course they do have shipping and handling fees which make small orders impractical.<br />
<br />
I, myself (who?) appear to have found that [[Jameco]] is good for small quantities of a fairly common part.<br />
<br />
I called up Digi-Key to see if I could alter an order I had just placed before it got fulfilled. My order was already far enough along that they couldn't stop it. I believe the phrase was "too far gone". That speaks well of their order fulfillment process. I hear Mouser should be in there too, but I've never had a compelling reason to use them.<br />

===Allied Electronics===<br />
http://www.alliedelec.com/Images/logo_allied.png<br />
[http://www.alliedelec.com/ Allied Electronics]<br />
Honestly I'm not sure if this is a mid-size or large distributor (how are we to tell, anyway?) Allied tends to deal more with "heavy duty" electrical parts (wiring, relays, electromechanical, etc. . .) rather than electronics. However, I've noticed that they do have some suppliers that Mouser/DigiKey don't have in terms of electronics components.<br />
<br />
=== BG Micro ===<br />
BG Micro http://bgmicro.com/ has been around for a long time.<br />
Some good deals on used surplus equipment.<br />
<br />
<br />
=== Jameco ===<br />
http://www.jameco.com/wcsstore/Jameco/images/jamecoLogo.gif<br />
[http://jameco.com/ Jameco]<br />
's catalogs have been getting fatter recently and their prices are good for common parts. Their Jameco ValueBrand parts are often much cheaper than the competition. (I have yet to notice the difference, personally -mdwebster) Jameco tends to focus on generic and older parts, where the giant supplier tend to focus on newer brand name parts. Jameco has a decent selection of cheap tools.<br />
<br />
For those living in the San Francisco bay area, particularly on the peninsula, Jameco has a will-call option. You can specify it when you choose shipping and then pick up the parts yourself in an hour or two, avoiding shipping charges. They are located just off highway 101 in Belmont, CA. You can also just drop in without placing an order first, and they'll pull they parts while you wait. Very convenient, if you happen to live nearby.<br />
<br />
=== JDR Microdevices ===<br />
JDR Microdevices<br />
http://www.jdr.com/<br />
has been around for a long time.<br />
They seem to be trying to get rid of the last few ICs and prototyping tools they have in stock and switching to desktop PC subassemblies.<br />
<br />
===Newark===<br />
http://www.newark.com/images/en_US/logo_nio.gif<br />
[http://newark.com/ Newark]<br />
My most recent "Newark in one" catalog is even thicker than my most recent Digikey catalog. ''(The "in one" motto and the swirly logo look identical to the Farnell logo. Is there some kind of connection?)''<br />
<br />
Newark usually has just about every odd semiconductor you might need in stock. Their shipping tends to be rather expensive, however (be prepared, as they won't give you a shipping quote until after you order, just like every other distributor), and they seem to really not like small orders, in my experience.<br />
<br />
Newark InOne, Farnell InOne, and [http://www.mcmelectronics.com/ MCM InOne] are all electronics distributors owned by the InOne Company.<br />
<br />
===Pricewatch===<br />
Pricewatch is good for locating certain computer gear at its version of the best price. Froogle is sort of the same thing, but without the seedy side filtered out.<br />
<br />
===Radio Shack===<br />
Radio Shack is OK if you need a common part NOW, but expect to pay probably 10 times the mail order price. In the past couple of years (2005-2006), I've noticed many Radio Shacks have ceased carrying ANY electronics parts. You're most likely to find solder, wire, switches, led's, and project boxes. The selection of transistors or IC's are poor to nonexistent.<br />
If you have a Fry's in your area, they have a much better selection, but their component prices are not much better then RS. Unless you need a part immediately, you'll be much better off getting it mail order.<br />
<br />

<br />
== Smaller and niche suppliers ==<br />
<br />
[[Anykits]] (http://www.anykits.com/) Large variety of kits for motor control, audio & lighting control, timers, RF modules, protocol/sensor interfaces etc..very very budget friendly :)And the kits are amazing in quality. <br />
<br />
[[Action Electronics]] (http://www.action-electronics.com/) Good place for soldering suppies, hand tools, small components.[NOTE: Unfortunately out of business, checked on 10/16/2010]<br />
<br />
[[Adafruit Industries]] (http://www.adafruit.com/) DIY kits and AVR programmers. Their open source AVR programmer usbtinyusb is especially recommended. Ok service and shipping. LadyAda has be active int the TV begone and Cell Phone begone community uprising.<br />
<br />
[[All Electronics]] (http://www.allelectronics.com) Corp. needs to even out their stuff a bit. Either specialize in a few types of parts or be more even across the board. Spark Fun Electronics appears to be trying to do it right. It is still weird that I can't just order a bunch of 0603 resistors from them. Seems like a no-brainer.<br />
<br />
[[Alltronics]] (http://www.alltronics.com/) is similar to All Electronics in what they carry. Fairly sure they're different companies with annoyingly similar names.<br />
<br />
[[American Science and Surplus]] (http://www.sciplus.com/) has a little bit of everything. Rubber spiders, speakers, prisms, lab equipment, electromechanical timers, Slinkies, motors, switches, fake vomit, glow-in-the-dark pencils, radio-controlled toy rats... Good selection of fans and motors, and an oddball attitude to boot. If you're near Chicago, their retail store is even weirder.<br />
American Science &amp; Surplus<br />
[http://www.sciplus.com/recommend.cfm?recommendid=11013&jump=index%2Ecfm%3Fstart%3D1 seems to have good prices on breadboards].<br />
<br />
[[Avnet]] (http://www.avnet.com/) Huge selection, but not really aimed at the hobbyist market.<br />
<br />
[[dipmicro electronics]] (http://www.dipmicro.com/store/) Parts, chips, microcontrollers, etc. Ship from Niagara Falls, Canada.<br />
<br />
[[Electronics Goldmine]] (http://www.goldmine-elec.com/) is another surplus warehouse. Don't expect to find any particular part, but they have good prices on what they do carry.<br />
<br />
[[Fastcomponents]] (http://www.fastcomponents.co.uk/) They only have packs, but the packs are good value.<br />
<br />
[[Futurlec.com]] (http://www.futurlec.com) I've been very happy with Futurlec. Their prices are outstanding, especially on value packs. Their customer service isn't stellar, but in the end they've always resolved any problems that I've had. They ship from Australia/Thailand, but their shipping prices are reasonable & the shipping is quick enough.<br />
<br />
[[Logical Systems]] (http://www.logicalsys.com/) IC Programming addapters. Surface Mount to DIP, many more than I thought there were.<br />
<br />
[[microcontrollershop.com]] (http://microcontrollershop.com) - Large selection of development boards, programmers, debuggers for microcontroller projects. All major architectures ARM, 8051, PIC, Atmel AVR, TI MSP430, Freescale HC08, HC12, etc.<br />
<br />
[[MPJA.com]] (http://www.mpja.com) - prototyping tools, components. Not a huge selection, but prices are low. If you order something that comes with an instruction sheet that was translated into English, the directions may be hard to decipher due to poor translation, possibly from Chinese. They ship from Florida.<br />
<br />

I want to see some competition in the micro dev/app board market. I just paid approximately 34.95 + its share of the shipping for a 32 bit ARM microcontroller on a PCB and with a USB device port on one end and a series of header sockets on the other. If that is considered cheap, then this is never going to take off.<br />
<br />
I realize that other authors will have different opinions than I, and that this entry is probably not going to remain as it is for long. Come on, everybody. These comments do not reflect the opinions of Open Circuits. They are only my own. Add yours.<br />
<br />
I personally stay away from app boards unless I absolutely need to use them because of the price. Also the components tend to not be in sockets, so if you blow a pin or two on that $100 app board, you need to replace the entire board as opposed to a $5 microcontroller. Unfortunatly, many of the better parts are only available in SMT packages. [[User:Mzoran|Mzoran]] 15:30, 16 December 2007 (PST)<br />
<br />
Competition?<br />
I see that there is a different [http://parallax.com/Store/Microcontrollers/PropellerDevelopmentBoards/tabid/514/CategoryID/73/List/0/Level/a/ProductID/423/Default.aspx?SortField=ProductName%2cProductName 32 bit microcontroller on a PCB for $20 + shipping]. It has a SMT microcontroller, but I see the same microcontroller is also available in a DIP package for easy solderless-breadboard prototyping.<br />

I've had great experiences with [[Mouser]] and [[Jameco]] for smallish orders (<$200). I've also had several good experiences with [[SparkFun]]. I now avoid Fry's. In addition to their horrible return policies, their stock is very random and prices aren't very good.<br />
<br />
----<br />
<br />
My personal experiance with Surplus Sales was very good. I would highly recommend them for anyone that needs a blower motor, hydraulic pump, etc. Good prices, good service.<br />
<br />
----<br />
<br />
See also the list at http://techref.massmind.org/techref/supplies.htm .<br />
<br />
----<br />
<br />
Don't forget to check [http://www.ebay.com ebay] if you're looking for fairly generic items. There are a number of suppliers that ship cheap components from China, plus a few who ship from within the US. I've gotten great prices on character LCD displays, pin headers, SMD LEDs, and PIC microcontrollers, among others.<br />
<br />
[http://ledshoppe.com/ ledshoppe] has good prices on LEDs (all pin-through-hole). They don't have any other components, but they do have dirt cheap bluetooth dongles and SD card readers that may be of interest. Shipped from China, shipping is free. Usually arrives in the US in about a week, never had a problem with them.<br />
<br />
----<br />
<br />
I'm not sure where this should go, but I find http://www.findchips.com to be ''very'' useful for finding parts. You just enter a part number (or part of one) and it will do a real-time check with several suppliers including Mouser, Newark, Digi-Key and Jameco, and tell you who has it in stock and at what prices (in most cases - some suppliers just say "call for price"). This one site can save hours of shopping around. [[User:KeithHearn|KeithHearn]] 17:48, 20 March 2008 (PDT)<br />
<br />
''Thank you, Keith. The Findchips website could save me a significant amount of time. The http://octopart.com/ website is similar -- once you know the exact part number, it checks with several suppliers and tells you who has it in price and for what price. --[[User:DavidCary|DavidCary]] 20:49, 14 November 2009 (UTC)''<br />

<br />
Should comments be moved to discussion and a consensus formed around factual information regarding suppliers?<br />
<br />
== Local electronics and surplus stores ==<br />
=== Surplus ===<br />
<br />
Sometimes it's difficult to tell from a picture on the web if something is really the right size.<br />
Local electronics stores let you see that it's exactly the right size,<br />
and often have a [[bargains]] bin.<br />
See [http://mightyohm.com/wiki/resources:surplus the MightyOhm Wiki Surplus] for a list of local Surplus Electronics Stores, plus some Swapmeets and Fleamarkets.<br />

<br />
I see from your comment on [[components]] that I've been a little over-zealous locking down pages.<br />
Oops.<br />
<br />
Thank you for adding good information to Open Circuits.<br />
--[[User:DavidCary|DavidCary]] 14:56, 17 January 2008 (PST)<br />
<br />
p.s.:<br />
There's a bit of an art to naming pages in a wiki.<br />
:''("I’m watching people at other places struggle to build wiki ... they’re making big long names that are hard to remember / match right ... and not inter-connecting them together. That is, they’re not building ideas on top of ideas." -- [http://communitywiki.org/TheoryBuilding LionKimbro])''<br />
<br />
When I mis-spell the title of a page, please use the (confusingly-worded) "Move this page" link in the navigation bar to re-name it to a better title -- preferably a correctly-spelled title.<br />
<br />
When a page needs to be deleted -- because all the information that was on it has moved on to some other, more appropriate page -- or because it's never had good information, only spam -- please slap the <code><nowiki>[[Category:AFD]]</nowiki></code><br />
link on it.<br />
Then, sooner or later, the page will be destroyed by the system.<br />
<br />
I apologize for not already explaining this stuff.<br />
See the "help" link in the left navigation bar?<br />
That's where I should have explained it.<br />
But (a) I worry that I'm already far too familiar with this software, so I'll write brief, cryptic statements that may technically be true, but aren't helpful to anyone who doesn't already know, or (b) I worry that I'll ramble on and on about some trivial feature, giving people the misleading impression that this is difficult to use.<br />
<br />
So: If you learn something about OpenCircuits that you wish you had learned a long time ago, help the next person by mentioning it on that help page.<br />
<br />

So ... have you seen our [[Open Circuits:Policy]]?<br />
--[[User:DavidCary|DavidCary]] 19:34, 11 March 2008 (PDT)<br />
<br />
== confused ==<br />
<br />
OK, I'm confused.<br />
It appears that you created the page [[Russ hensel test]], and then later created the page [[PIC Links]] with exactly the same content.<br />
<br />
So ... why didn't you use the "move this page" link at the bottom of the page to rename the page "Russ hensel test" to the better name "PIC Links"?<br />
<br />
If I find a URL to a really nice page about PIC electronics and firmware, which of these 2 pages am I supposed to put that URL on?<br />
<br />
Something like this happens all the time on larger wiki -- someone thinks we need a page on "such and such", and someone else independently thinks we need a page on the same topic, but names it slightly differently -- "SuchAndSuch".<br />
But this is this the first time I've seen the same person create 2 pages on the same topic with slightly different names.<br />
<br />
For now I'm going to pretend those 2 pages were created by 2 different people, and go through the standard process:<br />
* post a notice "suggesting" a merge<br />
* If no one objects in a few days (a week?), cut-and-paste the text (without editing) from one page to the other, leaving "text moved to page such-and-such" comments in the "summary" field, so people can see that I'm moving text, not deleting text.<br />
* Later: edit the page to have only 1 copy of duplicate information.<br />
I should probably document this process in the [[Help:Contents]] page.<br />

<div>{{mergefrom|How Should We Deal With Spam}}<br />
''(FIXME: summarize all the ideas in a nice list)''<br />
<br />
<br />
Possible solutions and what is currently being done to combat the growing spam problem.<br />
Note: if you have been blocked, and think it is a mistake, please contact one of the system administrators [[russ_hensel]], [[User:DavidCary]] or others ?<br />
<br />
== Spam Blacklist Extension ==<br />
<br />
The first way that we can decrease the spam problem is by using a ''blacklist'' filtering approach. There is a widely used MediaWiki extension called [http://www.mediawiki.org/wiki/Extension:SpamBlacklist Spam Blacklist] that checks instances of URLs in new posts against a shared blacklist. If a match is found, posting is prevented.<br />
<br />
On this server, this extension is currently configured to use the [http://meta.wikimedia.org/wiki/Spam_blacklist Mediawiki Spam Blacklist]. However, if this proves insufficient, a local blacklist can also be created.<br />
<br />
== reCAPTCHA Extension ==<br />
<br />
An additional method of preventing spam is to prevent automated posting. One method of doing this is through a [http://en.wikipedia.org/wiki/Captcha CAPTCHA]. A CAPTCHA is a [http://en.wikipedia.org/wiki/Reverse_Turing_test reverse Turing Test] that determines whether submissions and new user requests are coming from a human or not.<br />
<br />
The implementation that has been put in place for Open Circuits makes use of the [http://recaptcha.net/ reCAPTCHA] plugin. From the reCAPTCHA site:<br />
<br />
By default, CAPTCHAs are triggered on the following events:<br />
<br />
*New user registration<br />
*Anonymous edits that contain new external links<br />
*Brute-force password cracking<br />
<br />
== Other Suggestions ==<br />
<br />
[[russ_hensel]] suggests that a first step is to require all users to register, when they spam ( hopefully never ) delete them.<br />
<br />
I suggest that registred users that been around a longer time without spam incidents should not be subject to captcha. When doing lot's of edits, it's a real pain. [[User:Freqmax|Freqmax]] 16:04, 29 February 2008 (PST)<br />

== spammers ==<br />
<br />
I think I know how to dramatically reduce the amount of linkspam on the website i think if the administrators on this site protect pages that are frequently spammed such as [[Open Circuits talk:Community Portal]] that will reduce the amount of spam on this site because the spammers will not be able to edit those pages.--[[User:71.234.233.163|71.234.233.163]] 08:21, 2 June 2007 (PDT)<br />
<br />
:I just signed up a few minutes ago and noticed that there seems to be a lot of linkspam being placed by unregistered users. I don't want to exclude folk, but would only allowing registered users to edit cut down some of the spam? [[User:Autarch|Autarch]] 09:53, 13 June 2007 (PDT)<br />
<br />
::You are right.<br />

'''Anonymous Edits?'''<br />
Aloha from Honolulu David,<br />
I just got an email saying my page had been edited by an anonymous user. I don't know who this is, there is nothing his/her page. I would not be complainig if the edits had improved things, but all they did was delete information. Perhaps it is their sense of humor.<br />
I am glad there is the record of changes made, so I can try to recover what was removed. Just to let you know that apparently spammers are not all you have to worry about.<br />

<br />
P. S.<br />
<br />
I just finished replacing what had been rmoved. Again, I'm grateful for the changes records. I also left a note to whoever did it. I think possibly it was unintentional. I hope that's the case.<br />
<br />
It occurred to me that perhaps editing should not be allowed by anonymous users. Perhaps there could be a special page that allowed anonimity, but require identification from anyone who wants to perform edits on pages that others have posted.<br />
<br />
I don't know how you'd acomplish it. I'm just a bit po'd that this can happen. He could have easily deleted the whole page. I'm glad it was easy to repair, but I will be moving come the middle of August and I may not have email for a week or two, possibly longer. So if something like this happened then, I would not know for some time. Then it would be a problem. Forgive my rant, but see my point? I'll leave it at that and check back later.<br />

:Well, as with the banning of IPs, the spam problem could be adressed earlier, so it not even appears in the history. $wgSpamRegex is the better choice in my opinion. I'll come up with a regex somewhen this weekend or so ;)<br />
<br />
I suggest that ip blocks (see [[Spammer ip]]) like 217.141.249.0/24 (Interbusiness Italy) are used for any ip that spam on sight. And that users from such address blocks are blocked from doing any edits. But may create a user account and then edit. This is due that most spam is made from accountless ip addresses. This will allow everybody to still edit while preventing most spam. Maybe it could be made possible for people without sysop access to add ip-ban?<br />

::I have noticed that certain countries like China, Russia, Italy etc.. tend to be overrepresented. And ofcourse one should block ranges not individual IPs.

I think requiring a logon to make changes would cut out most of the spam. At this point, the problem is so bad that making things alittle harder for people to make changes is probably worth the benefits.<br />
<br />
Also, this isn't directly related to spam, but it would be nice if the site didn't put nofollow on all the URLs. I think more people would be willing to add project info pages to the wiki if they new it would make them more visable in search engines. The wiki is small enough at this point that if people start abusing this it would be easy to ban or delete their account( assuming the change is made to require a login to make edits)<br />

== Question 7 ==<br />
== accelerometers on a wheel ==<br />
<br />
Hello,<br />
I'm building a small machine that includes a wheel mounted on an axle. Four accelerometers will be attached to the wheel; equally spaced around the perimeter and diametrically opposite. The object is to sum the analog output signals to cancel out gravity but to measure simply the acceleration/decelaration of the speed of rotation. My main concern is how do I wire up the accelerometers? I would like to avoid slip rings if possible (the axle is 6mm diameter). Is there a simple RF emmitter/receiver available in an IC package capable of tramitting the analog output (+/-3v) from the accelerometer?<br />
Thanks for any suggestions offered.<br />
Vielle568<br />
<br />
EDIT:<br />
<br />
Thanks for all the feedback; very useful. <br />
In reference to answer 2 and concerning my project:<br />
What am I trying to do exactly? Well I am an instrument maker and I've been experimenting with electric hurdy-gurdies. The instrument functions by turning a crank and a wooden wheel rubs against the stings like a circular bow. One sting creates a rythmn when the crank is accelerated and I want to replace this string with electronics. In other words I want some kind of sensor that'll capture the acceleration pulses of the wheel that correspond to the rythmn. I want to use this signal to activate either an analog swith or an envelope follower to control an effect for the rythmn. <br />
The wheel is about 7" diameter and mounted on a steel axle in the heart of the instrument; it is not too easy to access but it is removable and sensors can be attached to the side faces without any problem. Use of slip rings makes installation difficult and transmission by radio would be a better solution. The receiver can be housed in the instrument's body beside the wheel with the other electronics. <br />
Maybe a gyro would be a better idea than two or more accelerometers but I remember reading on the spec sheet that gyros had a limited range of degrees. Maybe this isn't always the case? Could a gyro continuously monitor rotational speed on a rotating wheel or would this be impossible? <br />
<br />
[[File:VIELLE9.JPG]]<br />
<br />
The current system uses a series of small holes around the wheel rim and a small laser; a frequency to voltage converter sets a voltage level for the wheel speed and a comparator trips when the voltage passes a reference level; the output then triggers the analog switch. It works OK but the circuit response is too slow for fast passages of music.<br />
<br />
<br />
Vielle568<br />
<br />
=== Answer 1 ===<br />
<br />
Literal answer:<br />
<br />
There are several ways to power electronic devices while they are spinning.<br />
The most popular are "slip rings" and "mount a battery so it spins with the rest of the electronics".<br />
See "[[POV display]]" and [http://electronics.stackexchange.com/questions/12704/electrified-vertical-mounted-rotary-joint-questions "Electrified Vertical mounted rotary joint questions"]<br />
for some examples.<br />
Perhaps someone will write a "[[spinning electronics]]" page someday to list other ways to transfer power.<br />
<br />
Once you have power to your rotating platform,<br />
I'm pretty sure you can power the accelerometers using the standard circuit in the data sheet for that particular accelerometer.<br />
<br />
Once your accelerometers have power and are driving their output pin,<br />
there's a simple, low-cost circuit called a "op-amp summer" to sum the signals from two opposing accelerometers, to get the radial acceleration with gravity canceled out.<br />
There's a [http://en.wikibooks.org/wiki/Electronics/Op-Amps#Quick_Design_Process op-amp quick design process].<br />
I suppose if you were curious you could plow through the "summer" section of the "[[OpAmp Links]]" page, although they generally make it sound far more complicated than it really is.<br />
You're going to have various mis-matches from: accelerometers positioned not quite opposite the center of rotation; positioned not quite the same distances from the center of rotation; the accelerometers may have slightly different offset/scale errors; the resistors used to build the summer have small resistance errors; all of the above may vary with temperature, so even if you calibrate and cancel them all out at one temperature, they may no longer cancel out at a different temperature, etc.<br />
<br />
So gravity won't be completely cancelled out, but I think you'll be able to get close enough -- perhaps after a bit of tweaking and tuning.<br />
<br />
Since I don't know much about transmitting analog values directly,<br />
I might consider feeding the analog sum signal into a microcontroller (either directly, with a microcontroller with a built-in ADC, or indirectly through a peripheral ADC chip), then somehow transmit that digital data through visible light, infrared light, or radio.<br />
<br />
There are many small, low-power microcontrollers that can easily be mounted on a rotating platform and powered by a small coin cell.<br />
Perhaps a [http://jeelabs.com/products/jeenode JeeNode] mounted on the rotating platform, to digitize the signal and transmit it wirelessly, then use a [http://jeelabs.com/products/jeelink JeeLink] to receive that wireless signal and pipe it into the USB port of a PC.<br />
Or perhaps a couple of [[Arduino Links | Arduino]] boards, each one with an XBee wireless board plugged into a [http://www.arduino.cc/playground/Shields/Xbee01 XBee Shield].<br />
Or perhaps another [http://www.glacialwanderer.com/hobbyrobotics/?p=291 "Cheap Arduino Wireless Communications"] approach.<br />
[http://www.seeedstudio.com/wiki/index.php?title=RFbee_V1.1_-_Wireless_Arduino_compatible_node RFbee] apparently has a (Arduino-compatible) microcontroller and all the wireless communication stuff on a single board.<br />
Various other wireless and infrared communication techniques [http://www.arduino.cc/playground/Main/InterfacingWithHardware#wireless have Arduino libraries available].<br />
<br />
=== Answer 2 ===<br />
<br />
Less literal answer:<br />
What exactly is it you are trying to do?<br />
If you want to measure the acceleration due to the spinning at some point a distance R away from the center of rotation,<br />
perhaps a simpler and cheaper approach would be:<br />
* install a single gyro. (There's some low-cost gyros mentioned on the [[Multi-rotor]] page. You can mount it anywhere on the spinning platform; it doesn't have to be exactly R from the center of rotation.<br />
* Use the gyro to measure the rotation rate "w" in radians/second. (You might have to convert from revolutions/minute, revolutions/second, or whatever weird units that particular gyro uses).<br />
* Assume that a few "laws of physics" supported by centuries of experiments will continue to hold, and calculate the acceleration due to spinning as R*w^2. That acceleration is sometimes called a "[http://en.wikipedia.org/wiki/Centrifugal_force_%28rotating_reference_frame%29 centrifugal force]".<br />
<br />
== Question 6 ==<br />
Hello I have a problem with a temperature sensor it has 1 Mohm of resistance at ambient temperature and according with the specification the value has to be 2 Kohm, I think that the circuit is open but I do not why, do you Know any reason for open circuits, or for the sensors failure.<br />
<br />
Measuring 1 Mohm or more on a 2 pin temperature sensor such as a [http://en.wikipedia.org/wiki/Thermistor thermistor] or a [http://en.wikipedia.org/wiki/Resistance_thermometer resistance temperature detector]?<br />
Then it's probably permanently destroyed.<br />
Sorry.<br />
I usually destroy things by putting too high voltage -- now I know 120 V is too high :-).<br />
I suppose it's also possible it failed from over-temperature or other stress.<br />

== Question 5 ==<br />
== Recommendation for mains powered voltage regulator to power a CPU? ==<br />
Date: 2010-01-10<br />
<br />
Does anyone have a recommended high voltage AC/DC input DC output regulator? Something for powering MCU devices off the primary mains (115/1/60 US, 200/1/50 EU, ect), that supplies an output voltage of around 3.3V to 7.5V much like a low cost MCU based product might have. <br />
<br />
I'm looking for a better design of what might be called an universal off-line regulator. I found this ref, but those 1/2 watt resistors for a 100ma output don't sit well with me. http://www.discovercircuits.com/DJ-Circuits/images/offline5v.jpg<br />
<br />
I also found this linear non-isolated regulator, but I'm not happy with it because it's again wasteful, and it can't offer an isolated output if so desired. http://focus.ti.com/docs/prod/folders/print/tl783.html<br />
<br />
I'm thinking the solution will look something like this, perhaps with a switching frequency around 1kHz, or 10kHz what ever the low FCC limit is. http://i324.photobucket.com/albums/k352/kb1gtt/OFFLINE_REG.jpg<br />
<br />
The general theory in my above sketch is that the high side drive will buck you down to what ever voltage the chip is looking for. Current capabilities would be driven by the high side drive, and bulk caps. Something in the 100ma to 5 amp range would be nice for a broad range of applications.<br />

=== Answers ===<br />
<br />
You have a high voltage power source, and you need to drive a microcontroller at 5 V (or maybe 3.3 V).<br />
Lots of common low-cost equipment needs to do the same thing (alarm clock, microwave oven, UPS, battery charger, etc.).<br />
So you would think there would be a simple, common, low-cost, off-the-shelf way to do this.<br />
<br />
You also want it to be efficient (and therefore a switching rather than a linear regulator).<br />
<br />
Is this what the professionals call [http://www.smpstech.com/undest.htm "Underestimating Complexity of Power Supply Design"]?<br />
<br />
Practical answer 1:<br />
<br />
Don't be put off by the 1/2 W resistors.<br />
When a tiny little resistor is dissipating 0.001 W, and you substitute a big, scary looking 1/2 W resistor (of the same resistance), how much does that big resistor now dissipate?<br />
That's right, it's still dissipating 0.001 W.<br />
Many line-powered electronic devices use huge 1/2 W or 1 W resistors in places where they normally dissipate only tiny amounts of power, and so most of the time a much smaller resistor would be adequate.<br />
But the designers stick in those huge resistors anyway, because when you plug in the device, you *might* have a big surge of current through the input capacitor.<br />
(a) You don't want the capacitor to blow up, so you add a resistor to limit the current, and<br />
(b) You don't want the resistor to blow up, so you make it big enough to handle that brief surge of current, even though 99% of the time it handles orders of magnitude less power.<br />
<br />
Practical answer 2:<br />
<br />
Use a step-down transformer to convert 120 VAC or 240 VAC to a lower AC voltage, then -- assuming this is less than 6 W -- use a rectifier and a bulk cap to convert to DC. Pick the turns ratio so that you get anywhere in the range of 6 VDC to 40 VDC at the bulk cap.<br />
There are dozens of $10 transformers with a 6 VA rating that would be adequate.<br />
Then use any one of dozens of DC-DC regulators to convert that voltage to the desired voltage, 5 VDC or 3.3 VDC or whatever.<br />
<br />
There are detailed schematics and parts lists at:<br />

--[[User:DavidCary|DavidCary]] 06:12, 5 February 2010 (UTC)<br />
<br />
<br />
Theoretical answer 1:<br />
<br />
Why do we need that step-down transformer?<br />
To someone familiar with low-voltage DC-DC regulators, it seems like (theoretically) we should be able to leave it out ...<br />
Use a bridge rectifier to convert the AC to DC, then use a single-chip switching regulator (perhaps with external high-voltage buck transistor) to convert the resulting 170 Vpeak or 340 Vpeak signal to the desired 5 VDC or 3.3 VDC.<br />
<br />
Also, most switching power supplies I've seen above 30 W or so include power factor correction in order to meet IEC/EN61000-3-2 regulations.<br />
I'm pretty sure that an appropriate power factor corrector input stage can be built with a TL494 switching regulator.<br />
<br />
Alas, lots of plausible-sounding searches return switching power supply chips or circuits with a maximum input voltage no more than 50 VDC or 100 VDC.<br />
<br />
In particular, the<br />

refuses to design a switching power supply with an input voltage higher than 70 VDC.<br />
Rohm, Texas Instruments, etc. also have a similar mystifying limitation.<br />
<br />
Why?<br />
<br />
Am I just not looking in the right section of their website?<br />
<br />
Is it because of "extra-low voltage" liability laws and regulations?<br />
"When equipment is human-accessible, voltage and power limits of < 42.5 V and 8.0 A limit apply for UL, CSA, VDE approval." -- Wikipedia: Switched-mode power supply.<br />
<br />
Is it because the UL approval people (CE, etc.) are familiar with transformers, and because they are unfamiliar with anything else, it's too much hassle to get them to approve "new" power supplies no matter how much safer and more efficient and less noisy they are than the traditional power supplies?<br />
<br />
My understanding is that the low FCC frequency is just under 9 kHz.<br />
The [http://en.wikibooks.org/wiki/Practical_Electronics/PCB_Layout PCB Layout Wikibook] has some more information on EMI FCC testing.<br />
However, most switching power supplies I've seen run at 40 KHz, I'm guessing because it's well above human hearing (20 KHz) and so the annoying audio whine only annoys our non-human neighbors.<br />

=== Question ===<br />
Date: 2009-10-16<br />
<br />
Hi. I'm looking to design and build a PLL controlled 33 cm ATV downconverter. The purpose is to have a PLL controlled LO of somewhere around 850 MHz - shifting down from whatever frequency the user selects (via the DIP switches) in the 902-928 MHz band to 60 MHz (TV channel 3). A channel step of 1 MHz is sufficient, but it would be really convenient if the device had enough bandwidth to cover the entire 902-928 MHz span (users with computer tuners would pick 848 MHz to have 902-928 MHz go from 54-80 MHz and would be able to tell their computer tuners exactly where to look. Users using actual TV sets would have to change the LO to alter the tuning since TV sets are not as agile). You can check out [http://nsayer.blogspot.com/search/label/ham my blog] for more details.<br />
<br />
Where I'm at so far is that it appears that the combination of the MC145151 PLL, SA620 LNA/Mixer/VCO and the MC12080 prescaler together might do exactly what I want. But I'm not really an expert at such things. Is there an easier, cheaper, or easier to get set of components that can work together to achieve the goal?<br />

Does anyone have a simple circuit for Power over Ethernet (PoE) power supply? I have found a number of ICs that are supposed to help (e.g. MAX5940 .. MAX5943, LTC4257, TPS23750, ...) but most of the example circuits suggest output transformer and optocouplers. That would make my ~$20 design too complex and expensive. Do you know of any cheap and easy way to get 5V or 3.3V from PoE? Thanks!<br />

I really like National's LM5071 chip. Look at the non isolated example circuit on page 17 of the datasheet. It doesn't need a transformer or opto, but you have to be careful as the 5V RTN is NOT common.<br />

Feb '08: how do I add my c code so it will be colored in this wiki? I can have it export to a html file and rtf<br />
<br />
=== Answers ===<br />
Currently the fastest way to add c code to the Open Circuits wiki is to copy and paste the plain text, then add a "code" tag before and after the code.<br />
Like so:<br />
<br />
<code><pre><br />
#include <stdio.h><br />
int main(void){<br />
printf( "%s", "Hello, world." );<br />
}<br />
</pre></code><br />
<br />
We can also discuss the <code>main()</code> function.<br />
<br />
(hit the "edit" button to see how that is done).<br />
Is that what you wanted?<br />
<br />
Many IDEs colorize C code; that makes it a little easier to understand.<br />
If you want to see those pretty colors, some options we've seen so far:<br />
* copy-and-paste the source into your favorite IDE. Then it will colorize the code in the way you are used to (which may be different colors than what people with a different favorite IDE see).<br />
* Perhaps you could try exporting HTML from your IDE (or some other off line colorizer tool or script) and pasting it in. The OpenCircuits wiki accepts some html.<br />
* Other wiki use a "source" tag that colorizes C code automatically[http://en.wikibooks.org/wiki/C_Programming/A_taste_of_C]. Should we install that here at Open Circuits?<br />

Is there some other wiki for people to talk about audio electronics?<br />
Or is this Open Circuits the best wiki for talking about things like<br />
''"[http://analog.com/ Analog Devices] AN-221: The Alexander current-feedback audio power amplifier"'' by Mark Alexander<br />
?<br />
<br />
I think I would prefer to offload all the audio electronics controversies to some other wiki<br />
(but which one?).<br />
Still, it would be nice to have some "tips for high-power electronics" here.<br />
I imagine that tips page would list the various quirks of high-power MOSFETs, BJTs, TRIACs, and IGBTs,<br />
and (given a particular motor or speaker or other load)<br />
how to select one over the others,<br />
and various ways of working around those quirks.<br />
--[[User:65.70.89.241|65.70.89.241]] 07:17, 10 August 2006 (PDT)<br />
<br />
I just joined Open Circuits. I have been servicing and designing audio equipment for several years (Recording consoles a specialty) I hope you will have a section for audio electronics. I also work with video projection systems and theatrical lighting (stage struck at an early age) I play electric rock-blues guitar, so I also am interested in tube guitar amps (Marshall and Boogie). And there is a big difference in what a guitar player thinks an amp should do, and what a recording engineer wants an amp for. I think these are valid points for discussion.<br />
I've also got an interest in power supplies (my experience is mostly with linear, but I've started learning about switching designs). In fact that brings me to my question, I have some regulator designs based on the 723 that I'd like to share. How do I go about doing that? I built a replacement for a console /- 18V @6A supply when I couldn't find the original regulator devices. I used 723s with external series pass devices. The unit has been working for close to 10 years now, so I think the design is worth sharing. Is anyone interested? <br />
<br />
I also research discrete op amps like the Jensen 990. I've been working (on and off for years) on a clone of that using more modern, easily available parts and devices. Anyone else?<br />
Finally, in response to the first entry in this section, I too read that application note in Analog Devices Audio/Video Reference Manual. My copy is dated 1992. I've repaired a lot of amplifiers, but haven't built any. If anyone else is hip to this amp I'd like to hear about it. It is a very unique design. I also like the A75 amp design from Nelson Pass and Norman Thagard, and the Leach Amp by Marshall Leach. The last two are pretty normal as far as design goes, not as adventurous as the Alexander with its current-feedback approach.<br />

== red links ==<br />
<br />
The default skin at OpenCircuits currently has "red links" = page exists, "dark red links" = page does not exist.<br />
<br />
I find that confusing. (But not as bad as the wiki that has some links black-on-white, indistinguishable from normal text).<br />
<br />
'''work-around''': Register (it's free, and you don't have to give any personal information), then choose the "preferences" link in the far upper-right corner and then pick any other skin.<br />
<br />
The other skins have coloring that you may be more used to from other wiki: "blue links" = page exists, "red links" = page does not exist.<br />
<br />
--[[User:DavidCary|DavidCary]] 08:58, 18 December 2006 (PST)<br />
<br />
The colors are better in the other skins, but the navigation is worse. <br />

<br />
Lots of people talk about circuits for LED lighting at<br />

.<br />
Perhaps we can talk some of them into contributing here -- perhaps using a page or two of Open Circuits as a FAQ for LEDs and drive circuits.<br />
<br />
== tool lists ==<br />
<br />
Should we have an entire page on "tools", and mention it on the main page?<br />
That risks listing *every* tool anyone has ever heard about,<br />
like the page at<br />
http://massmind.org/techref/tools.htm<br />
.<br />
Yes, I'm responsible for uglier bits on that page;<br />
I think the wide variety of oscilloscopes are particularly confusing.<br />
How could we cut through the confusion?<br />
<br />
I see the "techniques" page already has a list of software tools.<br />
Perhaps it would be nifty to have a short list of all the tools necessary for each technique?<br />
Then a beginner would have a better idea of what tools he really needs to get (rather than looking at a huge list of every tool, and wondering for each one, ''"Am I going to regret buying it when I see it gathering dust? Or am I going to regret not buying it when I need it during a midnight debug session?"'').<br />

<br />
Hi, <br />
<br />
currently my board is using a 3V battery, in every 40msec it will turn on its RF to communicate with the base station. I face a problem here is that my battery life is badly affected. Turning on the RF with cause a current surge. <br />
<br />
Will this surge affect my battery life? If I use a supercapacitor does it helps?<br />

== MIDI electrical interface ==<br />
<br />
In my opinion, the MIDI interface got a lot of things right that too many later interfaces still trip over.<br />
<br />
* http://www.repairfaq.org/filipg/LINK/F_MIDI.html -- ASCII schematics<br />
* http://www.engadget.com/2005/08/30/how-to-control-csound-with-a-custom-midi-controller-hardware/ -- hand-sketched schematics<br />
* http://www.midi.org/about-midi/electrical.shtml "MIDI Electrical Specification Diagram &amp; Proper Design of Joystick/MIDI Adapters" -- well-drawn schematics<br />
* [http://en.wikipedia.org/wiki/The_MIDI_1.0_Protocol Wikipedia: The MIDI 1.0 Protocol]<br />
* http://en.wikibooks.org/wiki/Behringer_FCB1010_MIDI_Pedal<br />
<br />
It may look simple, but too often people try to "improve" it by adding or removing things without understanding, ending up with a worse system.<br />
<br />
Is there any other wiki that is more appropriate for explaining the low-level details of the MIDI electrical interface, and *why* it was done that way?<br />
<br />
I would be most interested in discussing new communication interfaces -- but is this really the right wiki?<br />
Or would http://en.wikibooks.org/wiki/Serial_Programming or the [http://interwiki.sourceforge.net/cgi-bin/picawiki.pl/StartingPoint PICA wiki] be better for discussing improvements?<br />

'''SPAM DELETED!'''<br />
<br />
I deleted a whole bunch of links that had been placed at the top of this page, probably by the same AH that did it to my page. I think the best solution would be to make it so no edits are possible without being logged in. Then there will be a record of who does this kind of thing. Then they can be banned from the site. I don't think that defeats the purpose of an open wiki environment, it simply means you have to register to contribute.<br />

== A post I left at the Schmartboard mailing list. ==<br />
<br />
Last week I posted to the Schmartboard mailing list asking about more interface types for their system.<br />
I made reference to sites like this and pleaded the case of individuals wishing to make projects that interface a little better than the methods available now. Neal Greenburg(VP in sales) replied that they had been kicking ideas around like what I was proposing for a while, and that he would like to get some feedback. So, if you're interested, head on over and pipe in. The basic request I made was asking for common internal pc interfaces(PCI, PCI-e, AGP, ISA, etc..) to be included as an attachable module.<br />
<br />
The reason for my request was that this would allow organizations such as this one to develop hardware that is now unachievable at a decent prototyping price(quantities in the single digits). Their modules allow robust SMD hardware to be hand soldered and connected to other modules, but interfacing to a pc or other system is limited to rs232. I left a much more in depth post there, and if you're interested, you can find it there.<br />
<br />

I'm not affiliated with schmartboard in any other way than as a customer. I'm sorry if this is seen as spam, it's not intended to be. If the general consensus is that this is spam, feel free to delete it.<br />

Thanks for your time, take care.<br />

To add to the confusion programming in embedded system can mean a person writing a program or a device called a programmer "burning" a program into a chip. This section is for the "burning" meaning of programming.<br />
<br />
* Many systems use [[JTAG]] for programming and testing. (Such as [http://en.wikibooks.org/wiki/Atmel_AVR Atmel AVR embedded systems]]).<br />
* Other systems use some other kind of in-circuit programming.<br />
* Some people use [http://en.wikibooks.org/wiki/Embedded_Systems/Bootloaders_and_Bootsectors bootloaders] to make re-programming a little quicker.<br />

<br />
== Individual Components and their Uses ==<br />
<br />
Note that components are sometimes characterized by their electrical characteristics ( resistor, capacitor... ) and sometimes by their use ( sensor ) and sometimes by other characteristics. This can mean that a component is listed twice. For example, a temperature sensing resistor is both a resistor and a sensor. We are listing in alphabetic order, but remember components may have various names.<br />
<br />
=== [[battery|Batteries]] ===<br />
Power Up.<br />
<br />
=== [[Capacitors]] ===<br />
Store charge and energy, block dc, filter. In their simplest form passive components, but now some are IC using switched capacitors to synthesize other and variable values.<br />
<br />
=== [[Connectors]] ===<br />
Join parts.<br />
<br />
=== [[demo board]] ===<br />
Lots of people put a microprocessor and most of the other essential stuff on a tiny little demo board, easy to plug into your solderless breadboard (or your custom PCB) that has just a few more things that make your project special.<br />
<br />
=== [[Enclosures]] ===<br />
Cover up.<br />
<br />
=== [[Integrated Circuits | Other Integrated Circuits ]] ===<br />

LEDs, photodiodes, optoisolators, LCDs, IR proximity detectors,...<br />
<br />
=== [[Oscillator]] ===<br />
Crystals, Ceramic Resonators, oscillators, ... Vibrate with excitement.<br />
<br />
=== [[Other Passives]] ===<br />
including Inductors and Transformers<br />
<br />
=== [[Microcontrollers]] ===<br />
Little Computers for your entertainment.<br />
<br />
==== [[Resistors]] ====<br />
and Potentiometers Resistance is not futile. In there simplest form passive components, but now some are IC using forming variable resistors and potentiometers.<br />
<br />
=== [[Transistors, Diodes, etc.]] ===<br />
Diodes, Transistors are described here. These guys are the basic semiconductors or solid state electronics. ( But not Light Emitting Diodes = LED or Photo Diodes which are listed under Optoelectronics. )<br />
<br />
=== [[Sensors]] ===<br />
Accelerometers, Gyroscopes, Temperature Sensors, Pressure Sensors, ... Find out what is going on.<br />
<br />
=== [[Switches|Switches and Relays]] ===<br />
Turn things on and off.<br />
<br />
=== [[Motors]] ===<br />
Make thing move. We include some circuits/chips for driving motors. Servos, steppers, and others.<br />
<br />
=== [[Modules]] ===<br />
GPS, Mobile Phone, RF Transceiver, Bluetooth Modules, ...<br />
<br />
=== [[Popular Parts]] ===<br />
So many parts to pick, but which ones? Why not pick a popular part, or a group of parts for areas of interest?<br />
<br />
== Where to Components Come From ==<br />
<br />
<br />
=== Component [[Manufacturers]] ===<br />
Links to homepages, phone numbers, contact info, ... There is often info under each component as well in the components sections above.<br />
<br />
=== [[Free From Salvage]] ===<br />
Dig in, to the free stuff, a list of links and a bunch of ideas on how to use your loot.<br />
<br />
=== [[Free Samples]] ===<br />
Free is nice.<br />
<br />
=== [[PCB Manufacturers]] ===<br />
contact info, PCB trace width/spacing capability, ...<br />
<br />
=== [[Salvage Ideas]]===<br />
<br />
Unusual ideas for the fruits of your labor.<br />
<br />
=== [[Suppliers]] ===<br />
Good places to buy, numbers to call, people to talk to, ... Get your low cost motor controller boards & motor driver ICs<br />
<br />
=== Fakes ===<br />
<br />
Beware!<br />

The project demonstrates how to write a FHSS MAC layer and use USB to interface it with a PC through CDC and WinUSB.<br />
Since the protocol is not hard-wired, it is easy to change the software to experiment with different protocols.<br />
A utility for pairing and configuring modems is included. The schematic, firmware, and host C++ software is provided.<br />

=== [[RS232 Dev Board]] ===<br />
A simple RS232 example project that takes all the power it needs from the serial port. Use it to power your microcontroller and communicate between serial port and microcontroller. Takes advantage of the fact that pc serial ports will accept 0-5V rather than the RS232 standard of around negative 10V to positive 10V. Very convenient - no external power required! Note that you may use either a 5.1V Zener or a 5V regulator.<br />

<div>== block policy rough draft ==<br />
<br />
The "Block user" dialog links here.<br />
I guess we are supposed to have some sort of "blocking policy" in place.<br />
<br />
What I ( DavidCary ) have been doing recently is:<br />
When I see that someone has added more than 5 links in a single edit that have nothing to do with electronics, I block their IP address for 3 months (1 strike you're out).<br />
(The majority of such spammy edits add hundreds of links).<br />
Also I revert the entire edit -- all of the links added in that edit are deleted, even the links might arguably have something to do with electronics.<br />
<br />
While it is tempting to block these spammers forever, I see that the wiki mentioned in the [http://wikiindex.org/WikiIndex:Blocking_Policy WikiIndex:Blocking_Policy] ban for 1 month.<br />
The [http://en.wikipedia.org/wiki/Wikipedia:Blocking_policy Wikipedia:Blocking policy] is to ban for 24 hours on the first incident, longer for repeated incidents.<br />
<br />
Is my randomly-chosen "3 months" on the first incident too long? Too short? ( russ hensel: not too long )<br />
What about on the second incident? ( russ hensel: forever plus some time, this is no accident ) ( russ hensel: if the spamming is to an electronics related site, shorter times might not be ok, but for porn.... )<br />
<br />

Ah, I see we have a bunch of sysops here at open circuits, and I've neglected to explain the mechanical details of how to ban someone.<br />

Then I hit the "compare selected versions" button (by default it compares the 2 most-recent versions, but you can play with the radio buttons to compare any 2 versions).<br />
That brings me to the "Difference between revisions" page, and shows me all the differences between those 2 versions.<br />
If it's a spam edit, I see a bunch of spam added on the right column.<br />
Some spammers also delete a bunch of stuff -- I see exactly what they deleted on the left side.<br />
<br />
Here I confirm that it really is [[spam]], not merely an opinion I disagree with.<br />
<br />
Once I am certain it is spam, I do 2 different things from this "difference" page:<br />
* block the spammer:<br />
** Near the top of the right column of the "difference" page is a "block" link. (This link only shows up if you are logged in, *and* you are a sysop). I click that to get to a "block user" page, with the "IP Address or username:" field already filled in for me. If some other sysop got here first, I'll see in the "Block log" at the bottom of the page the name of that other sysop, the time the block was placed, and the duration of the block. If I am the first, I fill in the other fields of the form. I set "Expiry:" to 3 months (see discussion above), "Reason:" to "Spamming links to external sites", and then there is "Other:" -- I don't know if I'm supposed to leave "Other:" blank, or if I fill in the name of the page that was spammed, or what. Then I hit the "block this user" button at the end of the form.<br />
* revert to the most recent unspammed page:<br />
** Also near the top of the right column of the "difference" page is a "rollback" link and an "undo" link. Not sure what the difference is. [[How to delete spam]] should explain how to use those links.<br />
<br />
(I've figured out a quick way to do both by opening each one in a new window, but I don't know how to explain it without making it sound far more complicated than it really is).<br />
<br />
(Is there some other page that explains this better?)<br />

<hr />
<div>However annoying spammers are make sure to check all revisions to upto the last good version. In order to not accidently delete valuable information.<br><br />
A good cue that spamming is occouring is large additions ie +12,000 bytes etc..<br><br />
<br><br />
1) Find the spammed article.<br><br />
2) Click on the "hist" link.<br><br />
:(diff) ([[hist]]) . . Toner Transfer; 16:26 . . (+12,082) . . 69.55.233.50 (Talk)<br />
3) Click on the "last" links until you find the last good edit.<br><br />
:(cur) ([[last]]) 16:26, 8 September 2007 69.55.233.50 (Talk) (12,395 bytes)<br><br />
4) Click on the good version.<br><br />
:(cur) (last) [[16:26, 8 September 2007]] 69.55.233.50 (Talk) (12,395 bytes)<br><br />
5) Select "edit".<br><br />
6) Write "rv" in the Summary field. (Optionally, put the source of the spammer (like 159.145.0.0/16 State of CA, Dept. of Consumer Affairs/USA = Spammer) in the Summary (helps keep track on trends on where it comes from).<br><br />
7) Click on "Save page".<br><br />
8) Done!<br><br />
<br><br />

== shortcut ==<br />
All too often, several spammers in a row hit the page, and the above process is necessary.<br />
But in the special case where the page is currently full of spam, but the previous page had no spam, you can take a shortcut -- on step 3, hit the "undo" link.<br />

OpenCircuits is a wiki to assist electrical or computer projects by providing<br />
project pages that are continously updated. Rather than having to read<br />
long discussion threads. That way you can get updated quickly the<br />
latest information.<br />
<br />
Here you can setup pages about original research, practical howto's, or an<br />
idea you have in electrical areas that doesn't have to be notable in a<br />
strict sense.<br />
<br />
You can freely assume other readers have technical proficiency<br />
<br />
Feel free to use wikipedia.org as a starting place or reference. But details<br />
on history, who, when and trivia belongs more on wikipedia. Thus, try to avoid making this a wikipedia mirror, but rather a complement to wikipedia.<br />
<br />
This place is built around the idea that sharing is better and we appreciate<br />
projects that allow others to reproduce or modify the projects here without<br />
restrictions. Please also understand that manufacturing comes with costs as <br />
most physical objects.<br />

Is this a good wiki to talk about disassembling commercially-available electronics, and modding them to add just one more feature?<br />
For example, [http://www.ifixit.com/Guide/iPhone "iPhone disassembly"] or [http://www.club100.org/library/ram100/index.html "A photo-tutorial on adding RAM to a Model 100"]?<br />
And discussing [http://www.oreilly.com/catalog/psphks/toc.html O'Reilly "PSP Hacks: Tips & Tools for Your Mobile Gaming and Entertainment Handheld"]?<br />
Or is there a better wiki elsewhere?<br />
--[[User:68.0.124.33|68.0.124.33]] 12:52, 10 March 2008 (PDT)<br />
<br />
[[russ_hensel]] This sounds more like opening circuits than open circuits. That said it is close enough for me. I would recommend that we keep this seperate from the open circuits so that readers do not get confused: that is it should have its own topic page and not be mixed in with current topics. What to others think?<br />
<br />
I concur. I think hacking preexisting electronics can play an integral role. --[[User:Wackyvorlon|Wackyvorlon]] 14:47, 19 May 2008 (PDT)<br />

<div>== In the Beginning ==<br />
<br />
<b>What the heck is this place?</b><br><br />
So Cina, Nate, and a guy named Aubry were all working on similar cellular projects using the [[GM862 Cellular Module]] but each project was different enough that we could not collaborate directly. However, we noticed that there was enough overlap between projects that certain things should be shared. Things like the audio biasing circuit, the power supply, and the footprint for various exotic parts. We wanted an easy way to share this information with others as well, and the concept of Open Circuits was born.<br><br><br />
<br />
We got the framework up (Cina is a pimp) in about 24hours. Even if you are completely new to Wikis, we're sure you'll find things fairly straight forward. Please use the following template (edit this change and copy/paste) into your posting as a starting point.<br><br />

== FAQ ==<br />
<br />
=== Cam Files ===<br />
<br />
Why can't I upload a *.cam file. It is used by Eagle for cam processors. There should be a better why to get help than posting to this page. --[[User:Linuxvolts|Linuxvolts]] 19:58, 23 May 2007 (PDT)<br />
<br />
Would also be useful to upload zip files, these could contain any file type or archives of several file types. Probably should be a file size limit. [[russ_hensel]] feb '08.<br />
<br />
Answer?<br />
I would sugjest something like sourceforge, bounty forge and others look around a CMS with drupal or joomla support can make your page building more automated and less fine grain work.<br />
<br />
=== C Code and Files ===<br />
How would I add my c code for my processor?<br />
Answer:<br />
C or other code that is just text can be put on any page, formatting may be a bit funny but anyone can cut and paste the code into their editor. I have found that you can get nice formatting if tabs are expanded to spaces ( many text editors will do this, Crimson Editor for example ) Make sure each line begins with at least one space. For more complicated projects with multiple files a zip file capibility ( not available now ) would be nice [[russ_hensel]] For low volume I, ( [[russ_hensel]] ), will ftp files to my space on comcast's ftp site, contact me.<br />
<br />
I would sugest something like sourceforge, bounty forge and others look around a CMS with drupal or joomla support can make your page building more automated and less fine grain work. They have CVS & Subversion.<br />
<br />
=== Upload Graphic Files ===<br />
<br />
Answer<br><br />
Upload with "upload file" link on left margin on most pages.<br />
<br />
=== Messages to Users ===<br />
<br />
Try to keep public discussions, go to the user's talk page and put a message there. ( how do you get there: go to the user's page, press discussion at the top of page. ) If a discussion is more general go to the topic and then press discussion. See: [http://www.usemod.com/cgi-bin/mb.pl?BackRoomDecision BackRoomDecision]<br />
<br />
=== unlinking section titles ===<br />
<br />
Currently at Open Circuits, many section titles are active links.<br />
However, someone at Wikipedia once wrote:<br />
: ''"Section headings should not themselves contain links" -- [http://en.wikipedia.org/wiki/Wikipedia:Linking Wikipedia: Wikipedia: Linking]''<br />
<br />
Do their reasons for avoiding such links apply to Open Circuits?<br />

<div>Open Circuits is a wiki for sharing [[open source electronics]] knowledge, schematics, board layouts, ports and parts libraries. Please help us to build this resource by submitting your descriptions, projects, instructions, techniques, board layouts, PCB footprints, and other documentation for electronics. This includes<br />
<br />
* [[Projects]]: open hardware [[Music Player]]s, [[atomic microscope]]s, [[PC]], [[PDA]], [[Open Mobile Gadgets|mobile phone]]s, etc.<br />
* [[Ideas]]: including [[Basic Circuits and Circuit Building Blocks]] -- Circuits you will use over and over.<br />
* [[Techniques]]: for doing things, often using [[hardware tool]]s or [[software tool]]s or both.<br />
* [[Components]]: Lists of components, where to purchase them, how to use them. For many components there are links to projects using that particular component, this is especially true for [[microcontroller]]s, for example follow the links down to PIC microcontrollers and you will find many project links as well as tutorials. General tips on [[connectors]], [[battery|batteries]], [[enclosures]], as well as more specific information on [[Popular Parts]].<br />
<br />
Many of the section titles are active links, click on them.<br />
* [[Test Equipment and Other Equipment]] See what is going on in your circuits, charge your batteries, etc.<br />
* [[Tutorials]] How to understand and plan what you are doing. These are for general theory, more specific information is linked to its topic.<br />
* [[PCB Footprints]] Don't reinvent the wheel. Known working open PCB footprints for various components.<br />
* [[HackerSpaces]] And hacker orgnizations. These are the white hat guys hacking electronics to make things. Includes DIY types, the people who read Make Magazine.<br />
* [[Got A Blog, Wiki or Website?]] Link to it on the [[Got A Blog, Wiki or Website?]] or [[WikiNode]] page.<br />
* [[Got a Technical Question?]] Perhaps it will be answered, perhaps not. Google for it first in the spirit of RTFM. Please do not ask us to do a school project for you.<br />

== [[Meta Open Source ]] ==<br />
Not projects or information on projects, but stuff about the open source movement ( mostly hardware ) itself.<br />
<br />
== [[Open Hardware Initiatives ]] ==<br />
The '''Open Source Movement''', typically covers '''Open Hardware''', '''Open Firmware''', and '''Open Software'''.<br />
<br />
'''Open Hardware''' is similar to '''[http://www.gnu.org/philosophy/free-sw.html Free] and [http://www.opensource.org/docs/definition.php Open Source Software]'''.<br />
<br />
The '''Open Firmware''' movement provides firmware (i.e.: micro-code specifically related to the subcoding of hardware devices) which you may also know as '''soft-IP''' or '''FPGA''' coding see [http://www.opencores.org Open Cores] for more details.<br />
<br />
Excellent examples of Open Hardware projects range from projects at ''OpenCircuits'' to [http://www.ethernut.de Tiny Embedded Ethernet Devices] and [http://www3.elphel.com Advanced & Intelligent Camera Designs] which provide solid-state camera and FPGA assisted hardware designs. A solid overview of projects can also be found at [http://open-innovation-projects.org/project-list/ Open Innovation Projects].<br />
<br />
== Licenses ==<br />
<br />
The most common "open hardware" licenses are the [http://creativecommons.org/licenses/ Creative Commons Licenses] and the [http://www.gnu.org/copyleft/gpl.html GNU General Public License].<br />
The GNU people wrote the [http://www.gnu.org/licenses/gpl-faq.html#DoesTheGPLAllowMoney the GPL FAQ]<br />
to deal with common questions and misunderstandings of the GPL.<br />
The GNU people go on to say<br />
: "We encourage people who redistribute free software to charge as much as they wish or can. If this seems surprising to you, [http://www.gnu.org/philosophy/selling.html please read on." -- GNU: "Selling Free Software"]<br />
<br />
For example, Linksys makes money selling (among other things) their [http://en.wikipedia.org/wiki/Linksys_WRT54G_series Linksys WRT54G series] routers, which use Linux under the GPL license.<br />
<br />
To understand what your entitlements and responsibilities are under the applicable license(s); each hardware, firmware and/or software piece you have either copied, modified, developed using tools provided or if you intend distributing your development, you '''MUST''' read each and every license, and be specifically aware that you may not mix such license(s) together unless they can co-exist under one umbrella license. For example you may modify, copy, enhance and distribute parts your project which are all under the same license e.g.: or .<br />
<br />
Some people are working on licenses that are specifically designed for "open hardware".<br />
"Open Source Hardware (OSHW) Draft Definition 1.0"[http://freedomdefined.org/OSHW].<br />
Wikipedia: "Open Hardware License"[http://daivx.webchuyennghiep.net/dam-cong-so-cho-mua-he]<br />
mentions<br />
"CERN Open Hardware License"[http://en.wikipedia.org/wiki/CERN_Open_Hardware_License][http://www.ohwr.org/documents/88]<br />
and the "TAPR Open Hardware License"[http://en.wikipedia.org/wiki/TAPR_Open_Hardware_License].<br />
David L. Jones has a short video that discusses open-source hardware[http://www.eevblog.com/2011/08/12/eevblog-195-open-source-hardware-explained/] and mentions several licenses, including the<br />
CERN Open Hardware Licence[http://www.ohwr.org/projects/cernohl/wiki].<br />
<br />
== Help Us Make Open Circuits Better ==<br />
<br />
What are we:<br />
<br />
Looks like we are defining this by way of who contributes and what. I ( [[russ_hensel]] ) am a new member so may or may not have it right.<br />
This is what I think:<br />
<br />
*An introduction to Electronic theory, suitable for the hobbyist.<br />
<br />
*Guide to locating and using components and tools.<br />
<br />
*Details on how to build various projects.<br />
<br />
*Building some sense of community among builders.<br />
<br />
There are two means of carrying this out:<br />
<br />
*Write material for the site or<br />
<br />
*Link to material you may have written or have located on the web. There is so much stuff on the web that lets not write it here unless it is at least somewhat unique. <br />
<br />
What do you think, discuss it here if very general, else on the discussion page ( link at top of page ).<br />
