ArrBot Assembled and Driving with Preliminary Software
Here's the Phase 1 ArrBot and ArrMote, completed and running.
I put the ArrMote electronics in a box to keep everything tidy. A plastic box There's a small hole for the Nunchuck wire, providing strain relief for the unit. The Nunchuck adapter is likewise twist-tied to the Nunchuck Connector. I think I'll put a switch on the outside... right now you have to open the box and attach the battery to the Pro Mini. The battery could be smaller, as low as 3.3V.
I did some fiddling with getting the nRF chip a bit tidier. I ended up using some short servo wires which were just long enough to raise the radio above the other wires. The 1000uF capacitor is way overkill but I had a bunch sitting around.
Here's the nRF24L01+. It is really neat and provides some pretty amazing capabilities considering its $1 price tag!
I think the Pro Mini 3.3V running at 8MHz is officially my favorite Arduino chip these days. Be sure and get a 3.3V FTDI cable!
The bracelet treads seem to be holding up pretty well. If you have a dud bracelet it will separate almost as soon as you start using it. If that doesn't happen it seems it will keep going for quite a while.
