This device generates 8-12cm discharges and 20-25cm poorly visible sparks.
This device can be build with elements, which everyone can get/find in their homes:
- the sphere is made of an old globe 22cm diameter covered with aluminum foil
- brushes are made of simple filament between PCBs
- the transmission belt is cut of an old ball (from its bladder)
- the box is made of chipboard
Some additional information:
- the aluminum foil was cut to 3cm wide strips and glued to the globe
- the transmission belt is 35cm long.
- the transformer has on out 30V of tension.
- because of heating of the motor, this device can work about 20 minutes long before a break has to be made
