Yes. the components for a smartphone board are really small so no one has figured out how to build one. My suggestion? Make one with a beagleboard or raspberry pi as a mainboard instead. Both boards are small and low voltage and linux which would be a great smartphone base. that is your best bet, btw it requires moderate electronics know how to rig up a touchscreen. You should get started familiarizing yourself with whatever electronics knowledge that you can find too.

Yes. The components for a smartphone board are really small, but lots of people have figured out how to build one -- see [[Open Mobile Gadgets]] for a list.
 
 
In particular, the Tux phone [http://www.wired.com/gadgets/wireless/multimedia/2007/10/gallery_linux_phones?slide=5&slideView=6] [http://www.flickr.com/photos/julianbleecker/225599650/] and the more polished-looking Openmoko FreeRunner  [http://openmoko.org/] [http://www.mobilegazette.com/openmoko-neo-freerunner-08x06x26.htm]
 
have open hardware and open software.
 
 
It's possible to build a small computer running Linux "from scratch" -- see [[motherboards that run Linux]] for some people who have done just that.
 
Perhaps you can use one of those smartphone hardware or other motherboard hardware as-is?
 
Or perhaps with a few blue-wires?
 
Or perhaps you could at least download the schematics and tweak the design for your new PCBs, rather than starting entirely from scratch?

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.

Redlinks defies convention and is confusing, making the wiki awkward for users. blue=link, red=dead link, violet=followed link. -- [[User:Robkam|Robkam]] 10:42, 9 November 2012 (UTC)

Do you have any ideas for contests or challenges that OpenCircuits could host or sponsor?

== Upgrade glitch ==
 
 
Recently the Open Circuits backend software was upgraded,
 
leading to every page on the Wiki displaying the message
 
''"Warning: preg_match(): Compilation failed: group name must start with a non-digit at offset 8 in /home/opencircuitsadmin/opencircuitsmediawiki/includes/MagicWord.php on line 872"''
 
and none of the content -- neither text nor images -- was visible.
 
(It is unclear to me if this was caused by the recent upgrade to MediaWiki or the recent upgrade to PHP).
 
 
As recommended by
 
https://phabricator.wikimedia.org/T60640
 
and
 
http://stackoverflow.com/questions/20905654/all-my-mediawiki-pages-are-blank
 
,
 
I applied the page from
 
https://gerrit.wikimedia.org/r/#/c/122450/
 
(the file
 
https://gerrit.wikimedia.org/r/#/c/122450/1/includes/MagicWord.php
 
)
 
and that mostly seemed to fix it.

=== How you can help ===
 
 
Alas, the above upgrade left a few pages on OpenCircuits that appear to have no content -- no text or image on the page, only the normal header, footer, sidebar that you see on every page.
 
 
If you find such a page, please append "?action=purge" (without the quotes)
 
to the URL in your URL bar.
 
The purge should fix it -- you should see the content of the page.
 
Thank you.
