If the grid goes down, generating power is going to be a top priority. The question is, how can everyday joe living in an urban area generate power without drawing unwanted attention? Gas generators are too loud, and solar panels only work on sunny days. Well, electronicsNmore came up with another option.
In this video, he shows how he built a 40-watt crank generator from a scrap dishwasher motor. It's fascinating how much thought he put into this project. He designed it so that the crank charges a power supply that you can use to charge devices. This way you don't have to be turning the wheel constantly.
