Simple power supply based on step motor
Abstract
There is more and more small of devices around us, like phones or mp3 players and as any other they needs batteries or other power supplies. It can be problematic if you don’t have money for new batteries and you don’t have charger — basically this what was my problem with mp3 player.
Interesting solution in its case may be power supply based on power of muscles. You just push or roll something and this creates power needed for the player. In this note I would like to present prototype of such device.
