I googled to get no help. I want to make a shake flashlight and I want it to run off a capacitor not a battery but I don't know how to figure out which one to use. I came across this http://homeenergypros.lbl.gov/profiles/blogs/correctly-sizing-a-capacitor but that's the closest I've came to anything.
If I were to have 5 volts at 30 amps just for example, how do I calculate what I need? I can identify the capacitors and do the rest myself I just need to figure out how to calculate the correct one for the job.
