I have built many coils small to medium.Me and all the other builders are familer with induced voltages from quite a distance away.Any thing metal,wire,ect..Anything acts like a ground or antenta.This means the nails in your ceiling.What I am getting at is that I moved into a apartment from a house.My upstairs room is my so called "shop".I had my routers and motems and all the goodies.Well used to have.My message is I knew better.The good side is Tesla coil won the battle.TESLA COIL 1,MODERN ELECTRONICS 0>>
A tip to all beginers.DO NOT FIRE TESLA COILS ANY WHERE CLOSE TO MODERN ELECTRONICS.BECAUSE THE WILL LOOOOSE.
