Introduction: High Voltage Pulse Generator for $8 (stungun)
This device is capable of generating high voltage arcs, which can be used as an ignition system for a spud gun.
Or other things where High Voltage pulses are needed for testing purposes.
This device is chargeable with a micro usb cable.
Warning:
This project uses High Voltage and can be dangerous if used wrong. Build and use this on your own responsibility and never use this on living things.
Step 1: Get the Components
Step 2: Perpare the Module
The module is a little bit to big to fit inside the enclosure.
First cut the excessive part from the tube off.
Than you can use a piece of sand paper or a milling machine to trim the height of the module to fit inside the casing.
When I was using the milling machine the tube broke and I was able to take the whole tube off, which was also fine.
Step 3: Solder the Circuit
- First solder the battery connector to the charge module.
- solder the GREEN wire of the high voltage module to the charge module "-" connection
- solder the RED wire of the high voltage module to one side of the switch
- solder a wire from the "+" connection of the charge module to the other side of the switch
Step 4: Test the Circuit
See how long you can make your arcs. this is important to know when placing the screws.
Step 5: Making the Enclosure
See where everything would fit inside the enclosure and make the holes for the components.
Step 6: Making the Electrodes
- Cut the red High Voltage wires to size
- Strip the red wires and solder spacers to them
- Drill the holes in the enclosure for the bolts to go through
- assemble everything as in the picture
Step 7: Final Touch
- Test if everything works
- Glue everything in place
Update: I added a lot of hot glue at the inside on the electrodes to prevent internal arcing
