My little circuit board controlling the thermostatically-controlled heated test bed thingy I was working on? The one I mentioned I had spent an hour getting good data from it? Yeah, I blew it up a little bit. Serves me right for making connections with power applied.
I have spare boards, since they were pulled from nearly-identical devices ages ago and I just kept them around, but it takes swapping the parts out. Oh well. Onward and upward.
By the way, that would be the SECOND thing that I caused to explode internally (no flying chunks yet thanks God! ) during the course of this project. Sigh.
At least I haven't tripped the 100-ampere circuit breaker on the 3-phase 230VAC service at work yet, while 3 other guys have.
