  • 5 V - 2 A power supply.

So called Tesla coils are used to generate spectacular sparks. This circuit allows you to touch such an electric arc (30 kV!) with your bare fingers. No harm done. 

Power supply via USB

Instead of a large and potentially dangerous coil, with a lot of energy involved, Elektor presents this (relatively) safe Tesla coil with limited energy, powered by a USB charger under 5 V. The maximum power consumed is 5 W which can’t cause much damage. Despite the staggering 30 kV, when you touch the sparks produced by our Tesla coil, you will only notice a slight tingling at most.  

Lightning in the living room

The Tesla coil is operated using a single push button (S1), which works as follows: 

  • A short press of S1 (less than 1 s) switches between the various operating modes: Turn on, 5-Hz pulses ’ 10-Hz pulses ’ 20-Hz pulses ’ musical scale, ’ turn off. 
  • Press S1 for 3 s to select the high-power (1 A) mode (red LED LED1 flashes); another 3 s press returns to the normal (0.5 A) mode. 

You must connect the Spiral MicroTesla to a reliable USB charger or USB adapter, but you must never connect it to a USB port of a computer! Keep sensitive electronics away from the discharges! 

Tesla coils aren’t kids’ toys! Tesla coils powered directly from the AC line can be deadly!
