MIT student Tyler Christensen created a musical Tesla coil hat for his Hallowe'en costume (it played the Mortal Kombat theme and the Harry Potter theme while discharging semi-tame lightning).

In fact, the boost never truly worked. If I play a mid to high note for a few seconds, the boost can’t keep up and it fades away.

I’ll fix hatcoil in February.
