I blew up a 3.3 V AC/DC module this morning. Still not sure why... Must have been a spark. Replaced it with another, and that seemed to work... until just now the Bluetooth beacon it was supposed to power stopped working. I was worried about overshoot from the cheap AC/DC output, but didn't expect it to break on first power-up. Now it's drawing 400 mA instead of 5 mA. I doubt that's all piped to the antenna... I guess that's why I bought more than one module. Pending investigation.

But that was really just procrastinating designing an authorization model for an object database.
