So, I recently made a working Green Lantern Power Battery with a custom made Green Lantern Ring.
I designed everything in Tinkercad and if your interested, you can download the Power Battery here, and the Power Ring here.
I designed the electronics using an Arduino nano, hall effect sensor, neodymium magnet, N channel mosfet, super bright green LEDs, and a Li-poly battery with re-charging circuit.
Here is a short video of it in action.
If anyone is interested in the circuit and/or code let me know and I will be happy to post it!
