Handheld Tesla Coil

It's a bipolar DRSSTC with one secondary driven and their bases connected. Power comes from 3 12V 7AH gel cells in the backpack stepped up to 250 VDC. The longest arc I measured so far was 20.5 inches. I haven't tried messing with the coupling yet; this coil might put out a few more inches of arc. Details here: http://www.lukekambic.com/plasmahandle.html

Power draw: 200-250 watts
Primary Fres: 295 KHz
Primary capacitor: 0.075 uF
IGBTs: HGTG30N60B3D (TO-247)
Filter capacitors: 10 parallel 120 uF photoflash caps
Driver: Steve Ward's 2006-era DRSSTC driver

Thanks to Steve Ward, Jimmy Hynes, and all the HV nerds on the net.

Can you link me to schematics or basic overview pictures of its wonderful innards? Pretty please? I have build TC's myself but this design really intrigues me

[lukekambic]

@TechnoW1zard As it happens, in a week or so I'll be putting up a website with some construction photos and details on this project. I'll put a link in the description. It's nothing too original electronically, though! It would take a cleverer soul than me to improve much on Steve Ward's DRSSTC drive circuitry.

This is a bipolar system, so there's a coil on both sides.

Thanks for posting the video. Very impressive! How big is your secondary coil?

[lukekambic]

@xee2vids The secondaries are 8 inches of 34 AWG.

[lukekambic]

The primary is inside the secondary, in the longer of the two pipes. It's 7 or 8 turns of 10 AWG wire.

It definitely helps to have all the right parts. I grabbed DRSSTC parts whenever I could for 7 years before I had everything needed to build one properly.

I'll definitely bring this thing out on halloween.

Just jump into a swimming pool to see what happen. lol

Wow look a new weapon for the cops!

[Zomik02]

At first I thought it looked like a bad idea, in that it looked extremely dangerous. While that opinion didn't change at all, it's still fucking badass.

[Alex1M6]

Badass! Sell it to law enforcement agency's and make a fortune lol.

"The secondaries are " - Do you have more than one secondary?
