How a mini Tesla coil works?
This model is known as mini Tesla coil 15-24V.
According to the manual in Chinese, this coil is the resonant with a frequency locking loop. By that, when a current is inducted on L2, circuit’s oscilation frequency is blocked on L2’s resonance frequency, with the function to keep the mini coil’s resonance. The audio signal’s voltage changes L1’s frequency, which resonates on L2, and then, sound is produced.
During the operation, transistors heat up too much, specially TIP42, that’s why it’s important to put heat dissipators before solding transistors.
Specifications
- Voltage supply(Vcc): between 9V and 30V.
- Input current: 2A.
- Power: 15W.
- Audio input: 3,5 jack.
Making the coil’s primary winding
To make L1 primary coil’s installation easier, first, wind the red wire in a cylindrical object. No part of L1 shall touch L2, the orange wire.
Mini Tesla coil demonstration
To have a good performance, I recommend to use a DC power source of 24V and 2A. This mini coil can light up neon lamps, fluorescent lamps and play musics from a cellphone or computer. The video below show the kit’s assemble and operation.
