An ARM920T board running Linux at 200 Mips with sound, Ethernet, CAN, 48+ bidirectionnal IOs and 4 DSPs for motor control (DC, Servos, etc...). Built as a student proof robotics design platform.
The Programmable Chip EEG is a Multi-channel electroencephalograph that could be a brain-computer interface.
Open Mobile Gadgets -- open source, open hardware, mobile phone
An open source, open hardware mobile phone in its preliminary development.
Music Players including MP3 players
TRAXMOD Open source MOD music player for dsPIC/ARM microcontrollers.
A simple RS232 example project that takes 3.3V TTL serial and outputs to a super-common RS232 connection. Insto-NMEA!
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.
Aim to build a general Converter between different Interfaces.
A great example project using the CP2102 USB to TTL UART IC as well as some basic battery holder info.
"#6" (the son of Chalk Roach) is a ultra simple microcontroller development board for Atmel ATmega32 = 16MHz, 2KB SRAM, 16KB Flash
- 24" Wall Clock A really big wall clock. Why? Well, cause it might look cool? Probably not. But we do use GPS to get the time! Groovy.
- POV display that spins around, giving the illusion of a large display. (DavidCary)
An indepth breakdown of the Port-O-Rotary. Some clues to help you avoid audio problems with the GM862.
- Das Brewmeister! : An attempt to wirelessly monitor temperatures of fermentation vessels
- Fermenter Controller : A web available fermenter vessel controller. Uses PICs, I2C, Rs232 and python.
Program your appliances to operate automatically in conjunction with your weekly and daily schedule, manually turn them on/off from your PC or use the controller as a process ON/OFF controller to regulate some kind of physical variable to the desired value.
An interesting project using an accelerometer and capacitive touch ICs.
Motor driver (H-bridge)
An atomic-resolution microscope.
- STM (scanning tunnelling microscope)
- AFM (atomic force microscope)
A bluetooth JTAG ICE debugger for AVR's!!!
A 125Khz RFID Reader with a simple RS232 based ring network - to allow connection of multiple units to the same control computer.
Consider using "RS-232D", aka "EIA/TIA-561". It has all the same wires and voltages as RS-232, but specifies a RJ45 connector.
Also consider RS-485.
(What is the name of the standard for RS-485 on RJ14 ("4 wire RJ-11") or RJ45 ?) (Ethernet? =P)
See "Build A Smart Battery Charger Using A Single-Transistor Circuit" by Ejaz ur Rehman. But be sure to read the "Reader Comments" at the end. The suggestion to add a zener diode is a good idea.
the Open Graphics Project
the Open Graphics Project a project started by chip-designer Timothy Miller. His goal, along with the rest of the project, known as the “Open Graphics Foundation” is to make a 3D accelerated video card which is fully documented, free-licensed, and open source. See the Open Graphics wiki.
The Amiga floppy project: designing, building, and programming an adapter to allow PCs to read from Amiga floppies. "This is really designed to be a community project(hence the blog with progress reports)."
This project is the building of an external USB amiga floppy drive controller. It sits between the USB port on a Windows PC, and a regular PC floppy drive. It will allow the PC to create .ADF images from an amiga floppy disk. This device is based on a Parallax SX28 microcontroller, uses Ramtron FRAM memory for temporary track storage, and uses another Parallax component for the USB interface.
See http://www.techtravels.org/amiga/amigablog for the latest in the blow by blow attempts to get this thing off the ground!!
Infrared Proximity Sensor Alfa Infrared Proximity Sensor Alfa in www.kedo.com.mx
The Infrared Proximity Sensor Alfa is a sensor to detect objects that can reflect infrared light. It has the following characteristics.
- Designed to detect objects that are close and can reflect infrared lights.
- It has a Infrared Transmitter to eliminate the dependency of solar lighting. So It can be used in the night.
- It has a Infrared Receiver that detects the close objtest that reflects the infrared lights.
- It has an incorporated Voltage Regulator
- The output is constant 5V when it is active and 0V when no detection.
- You can change the proximity threshold with a potentiometer.
A development board using Microchip dsPIC30F 5011. Contains information on development platforms and programming methods.
Some people derive an inordinate amount of pleasure from building semi-useful objects from zero-cost junk.
In the electronics field, most of the stuff built from scavenged components falls into 2 categories:
- ham radio transmitters and receivers -- built from a few transistors, caps, resistors, and wire
- BEAM robotics -- built from the above plus motors, solar cells, ...
According to http://coprolite.com/art12.html , "I'd love to hear about where you found your 8048. Take a picture of the host that you remove it from (CD player, truck, refridgerator, whatever) and I'll put your picture on a page that chronicles our adventures sifting through the rubble."
Challenge: Build a Wiki Device with a parts cost of no more than twenty dollars which is usable as a portable wiki. Include feature to make it compatible with a desktop or laptop computer's PersonalWiki, with a connector allowing this use. -- http://c2.com/cgi/wiki?TwentyDollarWikiDevice
The WikiNode project tries to link every wiki in the world together. Our "WikiNode" links to closely-related wiki (and their WikiNode links back).
If you want to talk about something that is not quite on-topic here (say, "desktop PC case modding", or "embedded Linux programming"), our WikiNode helps you find another wiki where people love to talk about that exact topic. The corresponding WikiNode on each of those wiki helps people who want to talk about "open hardware" to discover this wiki.
Is the Vislab puck suitable for this list?
