More about Motors
I received Revision 4 of the main boards last weekend. The part I was most nervous about was the motor IC footprints and soldering the tiny surface-mount pins. But that actually went pretty well, even though I forgot to use flux on the first attempt. I did make one major mistake on the board, wherein the controlled-voltage line to the micro-controller is missing. It's something that I had noticed and thought that I fixed, but somehow didn't actually fix. The good news is that it's really easy to jumper that connection. So pretty soon, I had enough components soldered onto the board to test the motors. The result from that was fairly disappointing: the controller would reset immediately when the motors were turned on. But it didn't ALWAYS reset and, when it actually continued working, the motors were turning strongly and motor IC was not getting warm. So, that was the silver lining, I guess. I tried bodging in various capacitors but, still the result was nearly alw...
