List of parts, references to physical assembly

[skylar]

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

1. 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.
2. 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:

• M3 screws, 100pk - http://www.amazon.com/Stainless-Socket-Internal-Threaded-Threads/dp/B00DD4T7JU/ref=sr_1_6?s=industrial&ie=UTF8&qid=1393999447&sr=1-6
• M3 nuts, 100pk - http://www.amazon.com/dp/B00DGB50FU/ref=biss_dp_sa2
• MPU-6050 breakout board - http://www.amazon.com/gp/product/B008BOPN40/ref=ox_sc_act_title_4?ie=UTF8&psc=1&smid=A28PCZ3GGXGBES

@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.
