Introduction: Mini Electronic Detonator

By

This inscrutable will show you how to make a simple yet effective electronic ignition system.

BTW, first instructable! :)

For this instructable you will need:

1. Switch.
2. Push Button (I ONLY HAD TWO SWITCHES)
3. LED (don't have one... find an old computer and take out the HDD light or the power light)
4. 9v Battery.
5. 9v Battery Connector.
6. Soldering Iron.
7. Multimeter (very helpful if using the headphone jack version)
8. Small box to put it all in.
9. Wire, lots of wire.
10. 1K resistor, to stop LED from burning out



OPTIONAL
0. 3.5mm Jack (take from mp3 player or other)
0. Cheap Headphones
0. Steel wool to test that it all works :)
0. Hot glue gun (also not needed, but helpful)

Step 1: Collect All the Stuff.

This is the general set-up you will be using.

As you can see in the picture once the ARM switch has been flipped the LED will come on showing that there is power going through the circuit.

When the FIRE button / switch is pressed the power is sent through the jack or just wires to steel wool. steel wool is very fine and will glow red hot when a current is passed through it.

Step 2: Having Trouble?

For this step you will connect everything up WITHOUT SOLDER just to check everything works.

If you are having trouble with the headphone jack version, scrap it and just have 2 wires.

Step 3: Put It Together

See the photo below of what mine looks like.

If you ever have troubles putting this together just e-mail me and i will reply ASAP.

As you can see in the photo below I don't have my led connected. ( glue gun fell over and melted it LoL)

Step 4: Test It Out

Here's a link to my youtube account showing the connectors and firing. :)

Have fun!!!!!!!!!!!

I like the jack version because it is really easy to use (harder to make though) and easier to transport.

Thanks for viewing
