Hey Andrew, I've been installing your electronics in a personal project of mine and have had some severe issues of my own making. I've built your Ray Gun successfully before so in a fatal combination of muscle memory and 4am grind fog I wired everything to the board before programming it. I tried to turn it on and when nothing occurred I realized my mistake. I de-soldered everything and it turned on when I plugged it into the PC but it just flashes yellow. When I try to reset it the LED turns solid red. I can't get my PC or Mu to recognize the board to perform a hard reset as suggested by the adafruit troubleshoot guide. Any suggestions? Or should I call it chalked, eat the $23 and just try again?
