Introduction: Simple Electronic Ignitor

simple ignitor to light off fireworks or explosives or just whatever. this project assumes that you know how to wire things together.

Step 1: Crap You Need

you will need the following for this project

1 toggle switch
1 push switch
1 old speaker/headphone cord (male)
1 9v battery
1 9v battery adapter plug in thingy
A small box to put it together in
alligator clips
headphone/speaker female plugin thingy
led if you want
some short pieces of wire
electrical tape

Step 2: Put It All Together

connect the stuff inside. connect one of the 9v battery wires to the toggle switch then the other toggle switch wire to one push switch wire and the other push switch wire to one of the wires on the little headphone jack thing (female) and then the other headphone jack wire to the other 9v battery wire. use electrical tape and tape all your connections. on the old speaker wire i had one that had a male output plug thing on both sides so i cut one off, stripped the wires and put alligator cips on the end.

Step 3: Using It

when you put either nichrome wire between the alligator clips and arm it and press the button it should heat up the nichrme wire enough to ignite whatever you want to ignite (fuses, black powdwer, flash powder, etc.) i couldnt find any nichrome wire so instead i used this jewelry wire i foung in my moms closet lol. i hadto take a lighter and burn the wire first because it has an outer coating on it which is kind of like wire insulation i guess but once you burn it off it should heat up nice and hot. i used tiger tail steel jewelry wire.

Step 4: Finished

go have some fiun with your new ignitor

This has to be the goofiest instructable I've seen yet. "Put all the crap into your box and hook up all the wires". Hahahahaha

hey i need to know how to wire up the headphone jack and how to wire up the headphone plug and also if any one can help how to connect 4 aaa batteries to work as a power supply for 1 circuit.

in serial. Pos-neg-pos-neg-pos-neg. probably need to solder them. This is how your cordless, rechargeable, power tools work. The batteries in them are usually "sub-C" batteries wired in series.

I have had success using stripped wire and liberal amounts of electric tape can also do in a pinch. No solder mess, and you can take it back down to it's components when done!

I did this in my project. It's not hard, but the poly wire is nothing but polution and cyanides from burning that. It's really just shorting the whole system and you'd be better off with some easy-peasy steel wool.

I've been interested in making something like this, but would need to make a spark to set off a black powder charge. However, I think it would need some type of step-up transformer like an engine coil (DC). This application would be for large, too-far-to-run, explosives that require a wire directly to the blasting cap/charge. Your "ible" is cool, but I wouldn't want to haul all that around just to light firecrackers or mortars. A 3-pack of Bic lighters from the convenience store for $1.50 seems much more convenient. Still, keep up the good work!

If you can't find nichrome wire use small pieces of steel wool rolled into a strip or check out local vape shops who sell either Nichrome or Kanthal wire (both are resistance wires). Any wire will get hot when you short-circuit it, but resistance wire gets hot without burning through and without damaging the rest of the circuit.

when you have a longer wire and you want the exact spot where it heats up, make a dent there.
Like hit the wire with something sharp or bend it to an edge (make it thinner).

that increases the resistance and damages the material in that spot and heats this spot faster than the rest of the wire.

Iv said in other instructables, but if you can't find nichrome wire, use pieces of thin steel wool. It works GREAT. wrap a small amount of steel wool around a firework fuse and attach it to a 6V battery, or 9V or experiment with others. IT works really really good... in fact i almost burned my friends carpet with it.

doesn't the battery just blow

perhaps would an Altoids tin work just in case you need it be smaller or if you can't find a metal box like me???

yes i just made one and because my mum doesnt like me messing with fire i detonate things out of my bedroom window works good buut steel wool is better

Yes i have in fact made one--i made a 12 switched igniter box running off of 12 volts. It has an indicator LED that tells you that its armed, and then the 12 push button switches. Cost me only about $40 for it all--not half bad! Haven't tried it yet! Hope it works...

author
Jason+Bourne made it!(author)2009-05-14

for the LEDs what kind did u use and did u use resistors so that they don't blow, and if so can i use a 9v? PLZ AWNSER!!!!!!!!!!!!!!!!!!!!!!!!!!!

So did it work?? I'm looking to choreograph a 40 firework show this year and something similar to your project would be ideal.

lager made it!(author)2008-12-04

Hellow i did something similar but my 9v baterry gets hot and it stop working anyone knows whats the problem? im using a duracell baterry and some wool wire . thnaks for helping

author
awang8 made it!(author)2008-12-19

To heat it up it short circuits the battery. This will make it really really hot then it will go flat so it cools and and stops working.

can u use cop[per wire insted of the other? and wats the headphone jack for?

k, few simple electronic questions.A)What voltage does a typical IR LED operate on? B) How much should perfboard cost? C)How do i use Transistors? D) How do I use a capacitor to regulate voltage?, and E) What does this symbol represent?

it is qutie funny that you have this instructable, about a week ago i made the same thing but is wireless using radio frequencies. i can make it go up to 200m with my special antennas. i can make and instructable for it if you want. i like to make big explosions.

author
funkymunky made it!(author)2008-07-25

yes plz make an instructables on :D

author
collard41 made it!(author)2008-07-25

have already,

type Remote Detonator with radio into the search.

just remote detonator will do but the title is above

have fun...

also if you dont have steel wool or nicrome use .7 mm or .9 mm mechanical pencil led and wrap the fuse around the center of the lead

i freaking put a lil wire across it and it cut through a plastic thing like butter! nzm good excelent!!!
