I know several of us have the 3DBotMaker electronic finish line. It uses 3 AAA batteries...well, the batteries in mine leaked or whatever and now the thing isn't turning on.
My immediate plan is to just replace the battery pack but in thinking more long term, does anyone have an idea on how to possibly make a power adapter for it?
I'm an electrical dolt so I have no real clue where to start or if it's even possible...or maybe one of you have already made one?
