This detonator uses only 1 AA battery, some switches, and a few simple electronics that can be had for FREE at any walmart or photo developing shop. (plus, it uses an altoids tin, which makes it just that much cooler)
This was largely inspired by the electronic detonators on this site, especially tetranitrate's https://www.instructables.com/id/EH6Q99985NEPA8L6YC/?ALLSTEPS
But I decided I didn't like the bulky power supply and multitude of plugs and jacks. So I changed it.
WARNING! this project uses Relatively high voltages and a decent ammount of current to boot.
DO NOT Hold the aligator clips in your hand when the plug on the end of the cord is inserted into the detonator!
DO NOT allow the Capacitor to discharge accross your Heart(it didn't kill me, but it was not a pleasant experience)
ALWAYS Discharge the capacitor with a screwdriver or a nail before working with it, even if you know it is not charged.
ALWAYS discharge the capacitor AGAIN after detonating something. the wires used explode(yes, I do mean explode) before all the current can be discharged and it will still pack a nasty punch.
Lastly, use common sense and don't do anything too idiotic(I know how hard this is going to be for a lot of you, but do try)
