Okay, so I’ve looked around for an idea for an instructable. And I found one that I want to do my own rendition of, the penny battery. So this idea is not completely original, I’m not claiming it as mine. I’m just using the materials and methods that I think will be the most effective. My hope is to power and LED light or a small fan if possible. But if I make the led die, then I have sufficiently surpassed my expectations. Let’s get started.
