Complete bundle including:
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.
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.
The Tesla coil is operated using a single push button (S1), which works as follows:
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!
