Full Size Potato Battery

Here is the full size potato battery. It is made from a plank of oak, with a plate of zinc and a plate of copper screwed to it. The metal plates have dimensions 80mm x 1000mm, and were chosen so that they would fit on a 1m plank. It hasn’t yet been tested, but we might schedule this for the workshop on Thursday … 🙂

The next stage is to attach the wires that will connect the potato battery to the microcontroller. We’ll use simple screw terminals, and screw the wires to the plates.
