cheap time bomb (fireworks detonator)
Heres my idea: Take a cheap dollarstore or walmart watch with an alarm. wire a capacitor where the little speaker/beeper thing it would store up a small charge and then have it arc or a fuse to light it.
so you set the alarm for the time you want it to go off, it goes off, builds a charge, arcs over the fuse and lights the roman candle, firecrackers, whatever you want.
would this work?
are there any ways of boosting the power of the arc or making the fuse light easier?
