I recently built an eggfinder mini and tested it to be working quite well. I took it out of my rocket box a couple months later to show a friend and, while it wouldn't power up, it got hot. I mean too-hot-to-touch on the center pin of the GPS module and the diode at the power point. Has this happened to anyone? There doesn't appear to be any physical damage or change since it was working, and the battery connection and everything is identical. Is there a logical place to start looking, or test points I should check to see if something is straight-up fried?
