Fred,
It seems to me that the first thing most people want to add to their
robots that is not supported on the handyboard itself, is IR
collission detection.
How about including a modulator and driver for IR LED's, and a
detector and demodulator circuit for IR phototransistors /
photodiodes?
What do other people think?

| I used the one available IR LED driver on the HB to drive a Radio Shack high-output IR LED. This, along with a Radio Shack IR decoder module (a little silver box about the size of a sugar cube that takes +5vdc and ground, and outputs a TTL level (...)
