Dave:

Aha! That's the other modification I was talking about last week. That wasn't the problem though. On a whim I tried using two 9V batteries in parallel and it worked. Now I just need something more robust than these little 9V batteries. I'm going to try using two 6 cell NiCD batteries in parallel as soon as I make a second connector. Otherwise I might have to try to find some RC batteries closer to 9V.

Thanks,
Dustin Webb

You need to either power both the robostix and the wifistix, or make
the mod described in this document:
