The beloved Tesla coil – now in portable form! We’ve seen loads of Tesla coils over the years, from desktop size to absurdly massive, but this is the first portable, battery powered version we’ve seen. Fun fact: you can even buy Tesla Coils on eBay! The evil mad scientist shown above uses a transformer to convert battery power into high voltage, high frequency, low current electricity. And of course, the results look incredible:
At the base of the gun is a 18v battery from a drill which is then boosted by an array of massive capacitors. Just pull the trigger to unleash a barrage of man-made lightning. Obviously, this is an extremely dangerous device for display purposes only and is not to be used as a weapon.
