Installed RBC upgrades

[Joe]

I installed the RoboBuilder 3-Axis Accelerometer and a Parani ESD200 Bluetooth Module yesterday. I used female headers from Pololu for both modules (and can confirm that there is plenty of room for that even on the accelerometer, even though RoboBuilder's instructions direct you to solder it directly to the controller board).

RoboBuilder's bluetooth module comes with a special header that has four female ports, but only three pins on the other side, leaving the reset pin of the BT module unconnected. I just used a standard 3-pin header and let the BT reset pin dangle. It seems safe enough; there is nothing loose in the area for it to contact. I previously tried snipping one pin off a 4-pin header, but that looked to me like the stub came dangerously close to contacting the plated hole on the controller board. I think it's safer to just let the extra pin hang off a 3-hole header.

I haven't actually tried to do anything with it, yet — my first goal will be to get a program to talk to my Mac over the bluetooth at all, and my next goal will be get it to report the values from the accelerometer. From there I can start working toward dynamic balance and such. I'll keep y'all posted...

Cheers,
