Tesla coil hat: "a really bad idea"

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). While freely stipulating that this is "a really bad idea," Tyler is still generous enough to document his project for others who might follow in his bad footsteps.

Really, it’s just a DRSSTC. Nothing less, nothing more, nothing fancy. It was a bit tricky to make a bridge appropriately sized, and even harder to make a boost converter for it. 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 think this is due to saturation of my boost core, but I haven’t really taken the time to do much on this since now I’m back in the gate driver world and also have to throw together my 6.131 power electronics final project. I’ll fix hatcoil in February.

  1. Wow.  This is a REALLY bad idea.  I love it. :-)

    (Son, if you are reading this article – don’t do this!  Yes yes, I know you *can*, but just don’t, ok?)

  2. If I play a mid to high note for a few seconds, the boost can’t keep up and it fades away. I think this is due to saturation of my boost core

    I knowww-ah! I HATE boost core saturation! Gah!

  3. This is so righteous! A wearable Tesla coil.  Now it just needs to be built into a stovepipe hat for the ultimate steampunk headgear.
