Nano Tess

Nano Tess

NANO Tess is an extremely small solid state teslacoil, designed to run from a battery supply and to be as small as possible.

Primary: 2T 1mm enamelled copper wire.
Secondary: 1.25" tall, 500T enamelled wire former 20mm diameter. wound with 0.08mm Wire from a 0.75VA 12V transformer secondary. 
Topload: 13mm diameter cupboard knob, sawn in half.

Nano Tess runs from a 12-18V supply, and used two half bridge mosfet drivers to give a full bridge drive. There are NO power mosfets.

Current Circuit (Subject to change.)

First light, running from 18V,

At this point it wouldn't work with its top load..

After some circuit changes, I blew two driver IC's due to the interrupter circuit stopping, both chips got very hot and died. I've found that the coil will run with a topload, but the breakout needs to be a long way away from it, (25mm or more) to give a spark,as the field stretches for at least 20mm up from the topload.

Nano Tess, complete with driver and battery..

I can actually walk around with it running , COOL!!!...

Close up of Nano Tess's output, about 10mm to air.

Input power 12V @ 170mA..
