Remarkably terrifying arcs from this tiny device. I was sceptical that the listing photo was representative of the actual product, so I was pleasantly surprised to see some strong arcs out of it. The primary appears to be a single turn and the secondary many turns on a flat PCB. One knob seems to control power and the other the periodicity of the discharge (which is loud!) Thoroughly recommend it to scare your neighbours and your children.
