A mad scientist read a graphic novel of a story of the battle between Edison and Tesla in the war to dominate the electric world – a graphic novel where Tesla had awesome Tesla guns. So he set about creating is own. And it’s battery powered.
If you’ve got all the hardware, you could even make one yourself since he’s posted up details on how he built it. Good luck finding all that stuff.
Happy sparking.
