Title: Water powered pump and dump AA charger.
Post by: stevensrd1 on July 19, 2018, 06:42:40 PM
Recharging a regular AA battery with a water battery. Simple circuit pumps up a capacitor with charge from a water battery then dumps that charge into a rechargeable AA battery to recharge it. https://youtu.be/lQXkfMlhQi4 (https://youtu.be/lQXkfMlhQi4)
