Autozone? I got a farily good one (which I haven't gotten to work yet, as walrus put it "electronics hate me") there for 10 bucks with tax.

the coil increases the voltage produced by the camera, therefore making the spark hotter, and to answer a earlier post i would suggest a momentary switch, as the power has to be stopped for it to leave the coil, im not to sure, but if you leave it on, there is a chance that the camera could bleed enough power into it and prevent it from firing.

Beebs, make sure it's a cylindrical one. The newer ones (box kind) don't work well to my knowledge.
Greihwak, it does make the spark hotter, but longer also. Good for multiple spark gaps, but the shock is not pretty.

im lost I have all the parts and have made many camera flash igniters but idont get how to wire the ignition points. I know that the reflector wire is the trigger and i dont see how it could work without it
has any one made this?
do you know what im talking about ?
is michael jackon really black?
will a 12 volt coil run off 1.5 volts?

here I tried it and it wont work maybe if i had a dia gram of the spark connect I followed the plan as exactly as I could, all it did was make a buzzing/whine noise for like 3 minetes and would not fire.

You guys really over complicated this. Soder wires from the points where the flash WAS connected, ignore the third middle wire completely. Putting the battery in the camera greatly simplifies things. Run one wire to a push button switch (doorbell switch works) then to the screws (on mine the screws ARE touching each other, which gets rid of adjusting them), out the other screw and back to the camera. Wire these parts.
1st Wire...Camera-Switch-Screw
2nd Wire...Camera-Other screw.
For multiple capacitors, rip 1 capacitor out and attach it to the other capacitor in series. If you don't know anything about electronics, or arm numbing shocks, don't try this.

Questions about the circuit in the camera

Is it series or parallel?

Is the trigger switch located at the low-voltage or high-voltage end of the coil? In other words, does the trigger interupt current flowing TO the coil from the capacitor, or current flowing FROM the coil to the screws?

This website has a page which takes you step by step on how to dismantle, wire and prepare. It really clears things up :D . You should be able to figure out the rest. http://www.i-hacked.com/content/view/181/48/.

What's a project box and where can you get them.

Also does the camera come with everything you need but the wires and project box.

a project box is a simple little electrical enclosure you can buy at radio shack for like $3, its a clean alternative to sloppy looking ignitions housed in one box
