What possible use could anyone have for a capacitor charger?
You'd be surprised /lie
Action packed video after the jump.
Is it not fascinating?
Step 1: Materials
1. Disposable camera w/ flash
2. Soldering iron and solder
3. A few square inches of 1/4" thick wood, acrylic, glass, etc.
4. Super glue / hot glue
5. Momentary push button switch
6. Syringe tips (Come with ink cartridge refill kits)
8. AA battery holder
Step 2: Disassembling the Camera
The next step is to take apart the camera. We must pretend to be the cameras friend so she doesn't get scared and call the police before you get a chance to harvest her organs. The conversation should go something like this:
Me: Why, Mrs. Kodak you sure do look warm in all those clothes.
Mrs. Kodak: Well it is kind of hot in here.
Me: No reason to be uncomfortable. Let me help you take them off.
Mrs. Kodak (shyly): I don't know, my husband is going to be home soon.
Me: What, that 24 shot roll of film? I bet he has never even properly pleasured you ... let me guess, he just sits inside of you as you expose yourself to him.
Mrs. Kodak (offended): Hey!
Me (seductively assertive): Its ok baby, let Billy show you how a camera should be held.
Me: There don't you feel better without all those uncomfortable clothes.
Mrs. Kodak: (blushes)
Me: (pulls out screwdriver and smiles menacingly)
Mrs. Kodak: Whats that flat head for?
Me: It puts the lotion on the skin, or else it gets the hose again.
Mrs. Kodak: Huh? ...... Ahhhhhhh! hrmfffff .... gurgle gurgle
Me: *Rips Mrs. Kodaks guts out*
Harvest the circuit board from the camera's insides, and dispose of the rest of the body in the woods.
Step 3: Modifying the Circuit and Assembling Board
Unsolder the capacitor and battery clips from the circuit board (make sure to keep note of their polarity).
Tip: Using two different colors of wire will help you remember polarity
There should now be four empty connections in the circuit board, two for the battery and two for the capacitor. Solder a foot long section of wire into each of these empty holes.
Finally, set the flash charge button/switch so that it is normally closed instead of normally open (picture 4).
The pushbutton switch, battery holder, and syringe tips will all go on the top of the board, while the circuitry and wire connections will go underneath.
Before drilling the acrylic (plastic, wood, w/e) piece, lay out the different components on the the top and bottom of the board to make sure everything will fit. Once you have found an orientation where all the pieces fit, drill holes in through the board, and attach the components.
Use hot glue to seal the syringe tips and battery connector (the pushbutton has a screw on nut) in place.
Step 4: Making the Connections and Adding Legs
(the circuit board battery wires)
1. Solder the positive circuit board battery wires to one lead on the pushbutton switch, and solder lead on the pushbutton switch to the positive terminal on the battery holder.
2. Solder the negative circuit board battery wire directly to the negative terminal on the battery holder.
1. Wire the negative circuit board capacitor wire to one of the syringe tips, and the positive circuit board capacitor wire to the other.
1. Glue on some legs. I used a combination of super glue and hot glue.
1. Most disposable camera circuits have LEDs to indicate when the flash is fully charged. Bend (or rewire) the LED so it is visible to you when you are charging the capacitor. It will be useful in letting you know when the capacitor is fully charged.
Step 5: Using
Insert a battery into the charger, and you are ready to go.
1. Insert a fully discharged 330v flash capacitor into the syringe tips. Make sure the capacitor has proper polar alignment with the charger.
2. Push and hold the button until the LED illuminates.
3. Remove the capacitor.
