I’ve finally finished the controller for the TVRRUG Open Motor Controller with a few really stupid mistakes.

Completed OMC Board

The mistakes I made are all dumb, the simpler one to fix was that I misread a brown line on a resistor as a red line. Much swearing and de-soldering ensued and 3 resistors where taken off and replaced. The one that caused me the most headaches was the fact that I started soldering down the long IC socket without checking all the pins had passed through. Stupid! Taking the socket back out I managed to break the socket. After getting a second socket I managed to rip one of the pads off the board while clearing the old solder out.

Luckily the TVRRUG are quite handy at solving awkward problems and with all the boards being open source I discovered (with some help) that a simple jump wire could resolve this problem (Thanks Mike the Bee).

Ooops

Once the fix was in place I ran the electrical tests and all was fine! Now I just need to think about how to mount all of these together and build the cabling for it.
