Hello, Quick Question. My friend has at his disposal a ShoeBoxCompressor for up to 4500psi (pounds square inch).

Right, For a while now I have been wanting to build a good electric glove. Some time ago I made one out of a camera with a 330V Capacitor. After that I brought 15 more 330V capacitors and tried to link them into series and parallel, neither worked when trying to charge with a camera (help would...
