Using a raspberry pi zero, a power boost 1000c and ntsc glasses you can make glasses like google glass. The glasses should run for about two hours but I used a smaller battery so you can change it to a bigger battery. Right now they are bulky but if you have a 3d printer it will be a lot cooler and not as bulky. I am working to get a 3d printer but that will be a while from now. I am still working on this project but should be done soon. Sorry about the circuit diagram photos I don't know how to do it on a computer.
