Complete project: Constant Current Dummy Load

[pstemari]

Yes, it was a little bit twitchy.  I pulled the breadboard off the shelf and used it to test some UPS batteries.  Setting the current to 10A was hard.

OTOH, the circuit had been sitting around for ages and I didn't recalibrate it before using it, so eh.

The circuit was quite happy to sink 60W without getting superhot, although the fan I stuck on the heat sink sounds like an F16 revving its engines when I turn it on.
