So what I want to make is a 60second timer using a 555. It should be a "one-shot" circuit, that is triggered by a push switch. Then the countdown from 60. Once it reaches 0 I want it to then activate a relay. HOW in the world do I do this:confused::confused::confused:....Thanks!

You power the circuit and you want a relay to turn on after 60 once you press a button or once the power is on?

How will you turn the relay off?

Well I really don't need to seeing as the relay will close a circuit containing a camera flash capacitor and some 50AWG wire. the wire be vaporized by the capacitor which will in turn trigger another camera device. So the closing of the relay doesnt matter seeing as the 50AWG will act as an "open switch" once it ceases to exist =)
