Could a phototransistor be used to trigger a somewhat high voltage capacitor discharge? Answered
Or would it require a secondary switching mechanism? I am trying to build a light trigger circuit that is as simple as possible. I have an idea to use an ir led across from an ir phototransistor and have it trigger when the light is blocked. I need it to run 450v through. is there a phototransistor that can do this and if not what might be a better idea?
Edit: This is to trigger a secondary acceleration coil in a coilgun. I am leery of using a relay for it because i don't know if that will cause too much of a delay.
