Well, I have no idea what i did except do something that 1) Made the board not work no more; and 2) Made me want to not think about it a whole lot (which further complicates giving any useful information). I was kind of hoping there was a standard, "Oh yeah that happens all the time here's a cheap source of those and that always fixes it", kind of reply.
Seriously, I did have a ground lead waggling around in the air (for to better poke the RST pin) and I think it was up against my LM7805 on my 1/2 size proto board, but I wasn't paying attention (or else I wouldn't've doohn THAT). Didn't see it coming, didn't expect anything. No smoke, but the only hot thing around was the 7805.
Oh here's one thing. I didn't cut my USB 5V jumper and I'm also supplying 12V (1/2 A wallwart) to the 7805 to the 5V input of my T3.2.
And another: 1.6 V on the 3.3V output pin of the T3.2. Upon measuring that I decided it was Stone IPA time.
<sigh> Tomorrow. __Marty
