Instead of a large and potentially dangerous coil, with a lot of energy involved, Elektor Magazine presents this safe Tesla coil with limited energy, powered at under 5 V. The maximum power is 5 watts which can’t cause much damage. Despite the staggering 30 kV, when you touch the sparks produced by our Tesla coil, you will notice a slight tingling at most.
It is operated using a single pushbutton, cycling through the operating modes: Turn on, 5-Hz pulses, 10-Hz pulses, 20-Hz pulses, musical tune, turn off. Pressing S1 >3 seconds switches to high-power (1 amp) mode.
You must connect the Spiral MicroTesla to a reliable USB charger or USB adapter. Never connect it to a USB port of a computer or a hub!
Complete bundle including:
- PCB with SMDs preassembled – yep, through-hole components need to be soldered –
- acrylic sheets, screws, nuts, spacers
- 5 V - 2 A power supply
