My own IR/gyro project challenge

Dear community, first post and HI :D

Anyways, I made a foolish bet as a pure hardware noob. I accepted a challenge from a friend who is a technical guru that I could put together the equivalent of a wiimote knockoff that would at least work with either the wii or glovepie.

I did a bunch of reading on wiimote schematics etc, but the real issue is finding parts- and no, taking apart a wiimote and rebuilding it is a cheesy option :P

Do you all have any advice?

Thanks!
