Introduction: Remote Ignition System: Camera Flash Method

This is an instructable to help you make yourself one of these babies. Charge the capacitor and flip a switch for it to discharge 300V of electricity from 1 AA battery through some steel wool for a nice spark and endless pyro-activities. Have fun, stay safe, enjoy! Watch the end for results!

i dont get the part where i have to sauder things

its spelled solder and pronounced like soder

Thats spelled with capitals and full stops. Mr know-it-all!

I know how to spell i was just telling him and besides i copied it right of the package for it so now what

Still... No capitals.

lmao! youre right /funny!

Spelt: Solder
Pronounced: (America - [saw-der]) (Everwere else (Including England and aparently Australia) - [sol-der])

TheParacorder (author)n00b0012012-04-13

lol look at the reply after reply and now i added on to it! SOMEONE REPLY SO ITS A BIGGER PYRAMID

 in australia we spell and say it as solder lol makes much more sense, now i know why people keep writing sauder

Its = Possessive (it has)
It's = Contraction (it is)

as long as we're being grammar nazis ;)

steel wool not needed just the spark ignites most every thing

squiggy2 (author)skelly74472011-06-16

but you wouldn't get an electrical arc from 300V. you need the steel wool because its high resistance makes it get really hot, but you can't actually produce a spark with such low voltages

sjoobbani (author)2010-09-02

Wouldn't it be better if you had reversed the switches, so that the Toggle would arm, and the pushbutton would fire?

napalm008 (author)2010-07-30

Does this actually work, if so then i am seriously considering making this.

adam-rawrrr (author)2010-06-04

where did you get the wire connectors from?

sas223 (author)2009-12-25

 if i,am  using two 9 volts in series do i still need the capacitor? thx in advance

milamber (author)2009-01-02

dude swap the push buton and the switch so u press to fire much cooler and less holding

pdub77 (author)milamber2009-06-11

I gotta go with milamber on this one. Flip the toggle on to close the circuit and charge the cap, then press the momentary switch to dump it. I did this with a coil gun I was working on. Nice video, btw, but it is hard to hear your voice over the tunes. Good work, though.

zach12 (author)2008-12-13

do you need to attach steel wool or can i just put the electrodes closer together. I wanted to use this on my spud gun.

TheDeviant13 (author)zach122009-05-14

Make a voltage multiplier using one charging circuit and some diodes and capacitors off of camera circuit boards so that you have a nice good spark coming off of it to ignite it without steel wool or anything else for that matter.

bballchamp1 (author)zach122008-12-14

steel wool helps a bigger spark, smaller the steel wool piece accross the leads the better. I haven't tried putting them close together to create a spark gap but you could experiment with it and see what result you get.

the 300 volts can hurt you badly?

Miel-jean (author)ilias2009-05-07

Volts don't directly cause the pain... it's the combination of volts and amps that hurts a lot. The thingo that causes the spark in an electric lighter (piezo-thingo) can actually generate up to 20 kV! doesn't hurt too bad though...

imkwl12345 (author)2008-12-23

um... u only kneed 9v too ignite steel wool... not 300

bballchamp1 (author)imkwl123452008-12-23

The idea was to have some fun, not make gradeschool circuit.

imkwl12345 (author)bballchamp12008-12-23

hey chill all im sayin is u dont kneed to go buy urself a camera

omnibot (author)imkwl123452009-01-03

You BUY your cameras?

bballchamp1 (author)omnibot2009-01-03

Was that a rhetorical question?... (always better to answer a pointless question with another pointless question)

omnibot (author)bballchamp12009-01-04

Yes ;)

ubr.bzkr (author)omnibot2009-01-26

Ha Ha Ha I get all my cameras for free. I just go to the photo department of my local grocery store and tell them I need a few used disposable cameras for a "science project" and vola, free cameras. they just throw them out any way so they will give them to you for free.

imkwl12345 (author)omnibot2009-01-12

did i say i brought any cameras? dumass... anyway what do u do... flog them?

omnibot (author)imkwl123452009-01-14

No, you're right. I must've been to tired and missed that. Sry I usually just drop by a photoshop on my way home or buy used flashes on ebay, much worse caps *muah ha ha*

Mattrox (author)imkwl123452009-01-13

this ways better and faster

tehpwnz0r (author)2008-11-13

please do this again but don't use the music because it's extremely hard to hear especially when your vocal instructions are then only thing we're paying attention to. very nice tho (: and make a step by step instructable too, damn you (:

bballchamp1 (author)tehpwnz0r2008-12-14

sorry i've been quite busy with school. If i get the time I'll be making something up. Also the website is back in production as it never got off the ground. Give it a week and the site should be up with a .com domain instead of ca. The site will have a full instructable too and will copy it over here as well.

tehpwnz0r (author)bballchamp12009-01-11

fantastic. thank you

mikedoth (author)2008-05-19

I'm still learning electronics but I have a question. How can a capacitor go up to 300v if the input is only 1.5v? I thought it could only go up to the input voltage. Does this use a toriod?

bballchamp1 (author)mikedoth2008-05-19

This is something i read but the capacitor holds the charge.. its builds up inside until it is full... all collected from the battery. When you discharge, all the stored voltage comes out. Thats why its a heck of a lot more than just your 1.5V battery's charge.

imkwl12345 (author)bballchamp12008-12-23

thats actually got nothing to do with it. the charge transformer changes the voltage. the capacitor just holds the charge so u dont have to sit there and charge it up when you take the photo

microman171 (author)mikedoth2008-05-19

There isnt a toriod but there is a charge transformer. The input is pulsed into the transformer and the output is higher voltage and lower amperage.

RDX HMX (author)2008-08-27

I was wondering if a 9V (square) battery could replace the AA.

imkwl12345 (author)RDX HMX2008-12-23

hey dont tell any 1 but u dont kneed the camera lol u can just rig this up with a 9v because its powerfull enough too light the steel wool. so u wouldnt kneed the push button or LED. jst a small box and a swich

DarkTrinity (author)RDX HMX2008-09-11

No a 9 volt battery by itself cannot replace the double A or it will fry the charge circuit.

jimihendrix4753 (author)2008-10-09

Dude make this into an instructable. Also, is it possible to reverse the switches so the momentary ignites the nichrome? And can you give the boxes dimensions. Finally, learn some transitional words. Thank you.

Samyo (author)2008-06-25

Very good tutorial, even for a noob like me. How does the battery fit into the equation though?

bballchamp1 (author)Samyo2008-06-26

The battery goes into the circuit board exactly how when it comes out of the camera when you take it apart. There are two silver clips, a positive and a negative, in which the battery slots into. When you take apart the disposable camera you'll know what i mean.

can u pls tell me the soldering part? cuzz i dont get it from the vid... i solder 3 wires to the button thingy but the bulb part is confusing can u tell me??

The LED part is just making sure that you have the correct + and - terminals connected proper. Once you have that just solder the connections + to + and - to - like you normally would and thats it.
