The drawdio is a tone generator that makes noises as the user draws on
paper using a pencil. I have not built or used one before, but there are
numerous videos up on youtube that provide a good demonstration of what
it is and what it does. I am all for doing more complicated and
original kits and projects, but I feel like the time limit until
ingenuity fest means that we should really be looking for a low risk,
proven project such as this.
Benefits of the drawdio: -excellent instructions already available on the internet -open source schematic and PCB artwork in Eagle format -involves both audio (noise from speaker) and visual arts (drawing)
-highly obnoxious -proven, low risk design -inexpensive BOM (few bucks each in volume) -easy to construct for soldering newbies (all thru hole components) -entertaining for adults/children/inebriated adults alike
I put together a BOM with digikey and mouser part numbers,
quantities, and estimated per-component prices assuming medium volume
(~200), which is attached to this email. In order to purchase PCBs,
someone will have to download the Eagle board file, install the free
version of Eagle, and cut gerber files. I work with Malaysian PCB houses
that can do either a 1 or 2 week turn with 2-day delivery.
An additional note - I forgot to include a AAA battery on the BOM.

Ok, here is my "mostly readymade" submission of a plan for the Ingenuity kits:
This plan gets us:
A- a really quick & easy to put together thing that is cheap ($1.50 each in quantity, can sell for $2-$3, or just in exchange for a donation or something)
B- An "Arduino Enough" thing that hopefully keeps us in the spirit and close enough to the letter of what we're supposed to be doing. If no one buys them, we'll have a bunch of extra Arduinos to do workshops and crazy stuff with in the future…
Also: If people really want a morse code blinky thing: http://brainwagon.org/2009/11/14/another-try-at-an-arduino-based-morse-beacon/ - which will blink the Diavolino's built-in LED.
C- Some additional tools so people can put these together about a dozen at a time...
