Instructables

Not your ordinary electronic detonator(With Altoids tin!!!)

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
http://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)

Rewire them to the butten and hand it to someone to snap a picture haha
Watch out with the circuit,make sure it's discharged before you touch it 4000 volts hurts,i know from personal expierience great ide i might try this out for fun

I am stumped on how to learn this stuff and even bought an electronics kit and that has helped a little but i would like to know how you learned this?

Nice instructable! by the way, do you mind if I post my own version of this? you will be given credit. Thanks!
Apples (author)  Flipyap4 years ago
Thanks!
Go ahead and post your own version, just make sure its significantly different (i.e. a different way of charging the cap or a different way of delivering the current) otherwise it's basically just a re-casing, and instructables already has plenty of detonators floating about.

Good luck, and remember that limbs are meant to stay on your body.

put the red button where it says ''press''
I placed 2 9v batters a switch and a male USB plug to make my detonator. i raped a match head with Nicrome wire as the fuse starter works perfect for me and cost me like umm 1US just for the switch
I think it is much easier my way
 much easier to rape it? :P
you raped a match head?!?!?!?!?!?!?!
haha raped. lol
Just fyi i think you mean wrapped the match head lol
cheers,

i would have said "anything I wouldn't do".

Great ible! just one note to all... Make sure you switch contacts are well separated and insulated because this type of charge can jump them if they are too close. could be dagerous (i got zapped but rockets going off could be bad too) cheers, Mspark400
if i used a 9volt instead of a AA wouldent it charg the capacitor faster or would it damage somthing
it would completely kill the charge circuit. trust me, i've tried it.
thanks

im making my own version of this with a box from a mini dv tape to set off model rockets, but dont u just need like a normal 3v current for it to work (2 AA or AAA batteries)???

Isn't it easier just to take of the flash from the camera and then solder two wires on each pole? Is it just because you want to have a nicer chassi or did I miss something?
Apples (author)  Behb6 years ago
unfortunately, the camera stops flashing after the film has run out, plus the camera has no safety switch or plug so you can detach the wires. My primary motivation was safety, so I elected to build an entirely new chassi so I could encorporate the features I wanted. Also, I wanted to have more room to maneuver as far as building goes, and I didn't want to bother with fixing the problem of the no more pictures w/o film(I'm sure it would be relatively simple, but there are a load of small parts in there). Plus, this let me make an altoids tin that explodes things. Much cooler than a camera ; )
it stops flashing because the film is no longer dragging on the wheel inside when you turn the wheel outside. just open up the back and gouge a hole where the little wheel is. then put the cover back on and you can turn the little wheel by sticking your finger into the hole you gouged out and turning it. works for me

hmmm. looks pretty good. however i think that the whole mono plug thing is over-done. looks nice though. would the super-thin copper wire from those plug-in AC-DC transformers for chrgers work as ignition wire?
i use really thin scrap copper wire, strip it, and take the little strands of wire from inside and those work great. im sure what your explaining would work
Apples (author)  recon5066 years ago
Sorry about the long response time, I've been swamped. I'm not sure if that wire would work, although it is certainly easier and cheaper to get. Let me know what happens if you experiment with it.
where did the battery connect to?
never mind... i got the stuff and it makes total sense

add a new switch between the a terminal of the battery and the pcb so that the capacitor won't keep charging every 20 seconds and discharge the battery
jdogjared57 years ago
ok, so now i got it so that when i plug the wires in, it charges but nothing happens, is the jewelry wire supposed to spark or something? Also, after i charge it, it seems to discharge somewhere because when i charge it, it always make the whining noise and then stops when its charged. But after i charge it, and it makes the noise, if i try to charge it again, it'll make the noise again like its re-charging. There is no spark or popping sound or anything. How do i make it work?
capacitors lose tiny bits of charge VERY quickly, so they recharge whenever. why do you think Kodak disposables discharge after about 20 seconds?
the noise is the transformer.......its discharging across the jewelry wire.....your probably using too heavy of wire. go for UBER thin....like.....as thin as paper

wouldn't using a normal switch on the cap burn out the switch???
but a saftey cover on the toggle switch and craft one or find one online for the other button

dear apples, My name is john and i am fifteen. i am building a electronic detonator (using your rubric) for my science fair project in chemistry and have some important questions on constructing this and would like some more info on how to build it, you can email me at madjohnny@nwe-usa.com thanks.
pyro(904)6 years ago
dat detonator is dope, im using this same blue print for my science fair project in chemistry.
would i be able to detonate fireworks with this
u should of use crocodile technology. it also has a 3d option so it's a lot easier. and u can make u'r circuit work, in realtime.
I know flash caps are 330v but what current should the switches be rated for? also, couldn't you just move the led/neon bulb (depending on which camera you harvest it from) from its spot on the PCB to the outside of the container?
Behb6 years ago
The circuit for the camera flash emits around 4000 volts at the second it's activated. Because the flashtube needs around 4000v to lit the, around 300v, capasitator unloads in the metal in front of the flash tube and it charge up a little bit before the Xenon gas in the tube can light. Because of this it doesn't matter if the camera does not flash when film run out. You only use the power given directly from the capasitator when it's shortcircuited (around 320V). I use a camera to fire of my spudgun but instead of having a glowing wire I make the two poles touch eachother inside the fuelchamber making the high voltage shortcircuit giving of heat and sparks. Perfect for lighting gas but you can't use this in a detonator tough. Do you also know that you can charge up the capasitator and then detach it from the camera while its still charged. After youve done this throw it to a good friend and see his facialexpression when he gets chocked;). You can charge it over and over again:)
