Introduction: Pocket Shocker
Disclaimer: This circuit deals with high voltage and is intended as an educational example. Please use caution when handling circuitry and make sure capacitors are fully discharged before servicing.
Now that we have that out of the way, lets begin!
This gadget was designed as a office prank for a friend who wanted something to shock her coworker.
What you will need:
- An old Disposable camera (you will need the Primary Transformer for the voltage step up)
- High Voltage capacitors (350V minimum) i used a bunch of little ones because i have a bag of them.
- a NPN Transistor: the one on the camera board is cheap and will fail quickly, I used a 2N2222 which are military grade and have a metal package but a standard 2N3904 will work if you have them.
- 220 ohm resistor
- Diode (Min 350V) I used a GP-20 because i have a bag of them.
- Push button
- Extruded Acrylic sheets
- Acrylic glue
- Laser Cutter
Note: a project box can be used instead
- M4 Tap
- Two m4 x 16mm Screws
- Screw driver
- Strip of copper
- Wire (i used AWG22 solid core, but it really doesn't matter too much)
This circuit is the ubiquitous camera flash shocker circuit that everyone has come to love. I have simply changed the transistor and capacitors to better suit my purpose.
Start by getting your hands on a disposable camera, anyone will do. Carefully take it apart, Make sure the capacitor is discharged by touching both leads with a meta screw driver or you will might shocked.
once you have your circuit, unsolder the primary transformer (the big one) you will need this.
The circuit was wired by point to point soldering since there was so few components.
The housing was constructed from 5mm thick clear acrylic sheets that were laser cut to make the layers. Then the first 4 layers were glued together using acrylic glue. the fifth layer is the bottom battery door and is screwed on.
I was fortunate enough to have a laser cutter and scrap acrylic at my disposal but you can always use a project box for the housing.
If you are lucky enough to have a laser to play with i have attached the autocad file so you can use or expand upon my idea.
Note: the file is in mm.
I look forward to seeing how other people build this,
