My workshop is full of junk, and sometimes I try to make something cool with whatever I got laying around... This is what I came up with last weekend...
......3/4 " arc......
.
CAUTION........HIGH VOLTAGE!!
...............................................
Materials:
1 Disposable camera with flash (Like Kodak FunSaver 35)
1 Piece of zip wire (like speaker wire, 2 conductors) about a foot long
1 Piece of 14 ga. solid copper wire (like Romex house wire, stripped)
1 Automotive ignition wire
1 Automotive ignition coil
2 Alligator clips (optional)
...............................................
Tools:
Soldering iron
Solder
Screwdriver
Knife or Dremel tool
...............................................
Use the film in the camera, then carefully pry open the back of the case.
.
.
Remove the film, and have it developed. Take note of the polarity of the battery. Scratch a + to indicate the polarity into the plastic. Remove the battery.
.
.
Carefully pry open the front cover. Be careful not to touch anything metal.
.
.
There’s hot leads all over the front. Carefully lay it on the table infront of you.
.
.
Find the capacitor. Looks like a small battery.(In this pic, it’s the black thing below the lens with the white rectangle on it. Short it’s wires with the tip of the screwdriver. Be ready for a loud spark! Short it a few times, until there’s no more sparks.
.
.
Find the trace on the board that goes from the capacitor’s inside lead (-) to
the outer flashbulb connection. It’s the one at the very edge of the board.
.
.
Carefully cut this trace next to the bulb connection with the knife or dremel... Don’t cut through the board, but cut all the way through the metal.
.
.
Solder one lead of the zip wire to the flashbulb connection, and the other lead to a nearby connection on the opposite side of the cut. (I used the connection for the negative battery terminal...) Put the front cover back on. If you’re using alligator clips, put them on the other ends of the zip wire.
.
.
Coil....and wire...
.
.
Remove the boot covering the terminal on the ignition wire, then pry the terminal free.
.
.
Bend the solid wire into a ’U’ shape, and crimp the terminal onto it. Solder the hell out of it.
.
.
Cut the wire and bend it like above.
.
.
Connect the wires to the coil... The wire that goes to the flash side of the cut goes to the + side of the coil. Insert the terminal. The solid wire should point to the negative stud on the coil. Bend it so there’s about a 3/4 " gap.
.
.
On the back of the camera, there’s a little ’star’ wheel. Spin this until it stops. That sets the trigger. Put the battery back in. Push the charge button on the front of the camera. Wait ’till the charge lite is flashing rapidly. Hit the trigger button (like taking a picture).
Should spark between the solid wire and the negative terminal. If it doesn’t, bend the wire down a little closer.
Please rate fairly. If you rate low, please explain...
like im gonna do all that so that i can make some fruity picture?
Uuuuuh.... You don’t take stuff apart too often, do you? This ain’t for taking ’some fruity picure’... If you don’t know the potential of this, DON’T build it. Trust me. It’ll kill you.

Apr 14, 2007 2:35 pm - pretty cool dude.
i made an arc about the same from one of those electric ball things you buy from spencers.
but good from being made out of junk.
4*
Jun 05, 2007 3:28 pm - I remember a year or two ago when I was making camera tazers I found out about the cameras with the flash that automatically recharges...That might work well for this just for fun but make sure you take the batteries out when you’re not using it or it drains them.
