That being said, if I could get a converter working, then it's possible to increase the size of the microcontroller and add support for PID or something, although at that point we're getting into SRX territory anyway.  Kind of unfortunate that the rules disallow it, although the rule makes sense. |
if it were a COTS converter for FRC it would likely be in the $20-30 range (if not more).
You also give up most of the usefulness of CAN while doubling your number of control system connections.
