This is electronics, but its more sensor side of things so I think that the programmers will be worrying about the sensors more than anyone else, so I put this here.
For those of you who don't know,
www.sparkfun.com has lots of good things to use. In the senors section, many combinations of accelerometers, gyros, already on breakout boards. In the wireless communication section, wireless radios (we cant use them in the competition, but its still fun to think of things we can do with them on our own
). In IC's > exotic, floating point math co-processors that could be useful to free up some cycles for other things.. They also have very cheap SSOP and SOIC adaptors. Less than $3 for most of the adaptors. I cant find them on the side column directly, but on the IC's> exotics page there is links to them with quite a few of the products, so it should be that hard to find.
Hopefully this helps someone.
EDIT: oh and if anyone is wondering... I'm not related to them in any way... Just impressed with what they have.
