That Tesla coil is AWESOME: can spark little lightnings and play music from your smartphone!

DISCLAIMER: keep ANY electronic device far away from the coil, it generates strong magnetic fields that can interfere and cause unexpected malfunctions

I designed the toroid to increase the electromagnetic field: needs aluminum coating connected to the top of the coil, and works!

But the coil gets hot easily, so i designed the bottom upgrades to increase the efficiency of the fan, rising that and the entire body from the floor to facilitate air flow, and avoiding direct contact with the rotating fan that may be dangerous.

Bill of materials: 4x M4x50 Screws with nuts and washers, and a tinfoil

That's all, enjoy!
