design for the NRF24L01 radio transceiver. Lots of small parts and you get a functional
2.4GHz radio when done. I have some commercial modules ($14.95 from Spark Fun)
so the acid test would be easy to setup.

Hi y'all, To make the challenge to be functional more interesting, I have some analog muxes I bought a reel of on ebay I will contribute 100 of if DJ will handle the kitting of them along with his boards. They may provide extra soldering challenge, since they were made in 2000, are on tape, and have NOT been stored in dessicant or anti tarnish environment since new.
