List of parts, references to physical assembly #3

@jonmagic is an english version of the robot hardware assembly anywhere? I took a quick look but didn't see it.

we should also make a parts list. if you share yours I'll probably order a bunch of the necessary parts and make a second prototype at home using my Spark core.
if you've got links to assembly instructions we can reference, I'd love a look.

excited to start thinking about this more Tuesday.

@jonmagic I was thinking that a Spark core ($40) could be a sweet alternative to the Yun. I'll build my model up this way and we can compare. Also, the kids can flash the chip via Wifi and/or write the app in a web browser. Moreover, perhaps the Spark guys would be up for sponsoring the event. (spark.io)

Parts sourcing is important! and time consuming. Here are some handy links:

@jonmagic FYI, DigiKey has the MPU-6050 on reels at around $6.31 each, so i guess if you have a good supplier connection you can get the part pretty cheap to print on a breakout board.
