how to make a simple detonator? Answered

how can i make an electronic detonator for fireworks?


buy what you need - a lot more reliable.

And thus safer -- see my other comment.

There seem to be some similar instructables in the Related column at right, and a keyword search might find more.

I'm going to assume you've already read and accepted all the standard safety warnings, and know what the legalities are in your area. Evolution takes no prisoners.

STRONG SUGGESTION: Whatever you do, make sure it has extremely strong rejection of false signals. The last thing you want is for some random bit of radio noise to trigger it when you aren't ready.

PM me , and ill show you a rather cheap long distance transmitter receiver pair easily converted into a wireless detonator with the addition of a 9v battery

Do you need it to be remote controlled? Or is on a wire fine?
Simple method:
Run a very fine piece of wire through the charge/explosive/whatever you need to be ignited. Nichrome wire is great if you have any, but regular fine copper wire is alright.
Connect the ends of that piece of wire to 2 other thicker wires, and run them to a power supply. Something like a 12V car battery works alright.
Connecting the wires to the battery should cause that small piece of wire to heat up, hopefully igniting the firework.
If not, put more car batteries in series to get more current flowing through the wire, and hence more heat.
