Coil progress




















I wound the primary coil and finished all the wiring except for the spark gap and 12v power supply. I also wound the secondary but have yet to photograph it.

Table top Tesla coils.














I have a great combination of parts and performance for a small table top Tesla coil and this will be the second in this line that I have built. This is the lower half of the setup and I still need to wind the Primary and Secondary coils.

I just finished building Franklin's Bells. The bells and hardware are all brass. The terminals are vintage as are the Bakelite standoffs used for the base of the bells and the terminals.

Electrostatic bells like these are often referred to as Franklin's Bells, after the eminent American scientist Benjamin Franklin, who installed them in his house to warn him of approaching thunderstorms, as is recorded in a famous portrait of Franklin observing his set of electrostatic bells as a thunderstorm raged outside. This electrostatic device actually was invented in about 1742 by Andrew Gordon, Professor of Natural Philosophy at the University at Erfurt, Germany. Gordon's Bells constituted the first device that converted electrical energy into mechanical energy in the form of continuous mechanical motion, in this case, the moving of a bell clapper back and forth between two oppositely charged bells.

Franklin made use of Gordon's idea by connecting one bell to a pointed rod attached to his chimney and a second bell to ground. This pointed rod discharged electrical energy from heavily charged passing clouds that would cause Franklin's set of Gordon's Bells to ring.

WC Tesla coil revise




The WC coil went through numerous changes. The primary had to be changed after the secondary was replaced. I replaced the spark gap after many failed attempts at making the rotary gap work properly. The new static gap works wonderfully. Such is the life of a Tesla coil.

Control we have a problem.


This control box which I used to control power to my larger coils suffered a catastrophic failure a few weeks ago while running my six inch coil being powered by a NST stack of 3 x 15kV 30mA. I don't think it was the power I think it was a short due to the tight confines in which I placed all of the electronics in this box. I have always felt things were a bit tight but never could find reason to change it seeing that it has proven good in hard service for over 3 years. So I'm working on a new control box that will address all the possible issues I saw in the previous one. RIP

More power please.



I just picked up this
Potential transformer. It is 70:1 ratio, 8400v primary, and 400va. This is a smaller version of a "Pole Pig" the big gray cylinders you see on top of power poles. This will give a large Tesla coil what it needs to really put on a show. They are deadly and would not ask permission to kill you if you make a mistake with them.
