anthropy, ordered a second hand 800w car alternator for 20€, want to try hook it up to my old exercise bike and see what I can get out of it, maybe charge some 12v batteries with it if it works
now to just get a v-belt and some mounting and tensioning gear, I already have a battery and charge controller that should do the trick, it'd be amazing if I could make this whole thing work for less than 50
