i have been lucky with not blowing any electrolytic caps....yet lol.
i did a good job with a soic 8 mosfet h bridge though, made some code changes and forgot to change one pin value in one place in the code, considering the datasheet says it was made with non flammable materials it certainly did a good job of flaming up and burning with a nice flame for a while, and with a couple of amps going through it the legs welded themselves to the pcb pads and seperated the copper tracks from the board, that was an experience lol
