    interesting power supply for raspberry pi

    benlikos

      so i was browsing radio shack for a 3.7v lithium ion battery  because i had just made a  3.7v to 5v dc-dc usb adapter with three usb ports in it to power my raspberry pi well any way i was browsing and the idea came to me. i new potatoes cold produce around 1.2v

      with some copper and zinc. and my adapter needs 3.7v so i cold get three and one 12th potatoes link them up and take some copper and zinc material and stick them in each end and i have a 3.7v potato battery. but the raspberry pi doesn't needs 1000 mAH and the potatoes only produce 3 mAH /
