have not got into one post pics
continuation
height of the entire structure 4.3metra
resonant frequency of 35kHz
MMC 1.2mkf

soon switch to full power

test run on video:

It looks impressive, but i don't see any point of using so much parts just to get result like that. I like to be able to move DRSSTC myself with small hatchback , not with truck

At least can you hit my numbers, 800Vdc and 3-4kA ? (CM600 full bridge)

Lovely Russian craftsmanship!

You get my seal of approval :)

The coil appears to be magnifier if im not mistaken. Could you share more design details?

My reaction too...

Jeeze, well i didn't expect this today. largest one out there?

Zilipoper you never stop amazing me! Love the bridge construction. Coiling must be your full time work over there, what a fast build. I really hope to meet you one day at a Teslathon!

Actual public perfomance is a bit less amazing however :)




It's really amazing that it actually worked a bit during tests

Re: MUSHROOM DRSSTC
Thomas W, Thu Jul 17 2014, 09:04PM


How come... those were tiny? yet the test ones were so much larger. Kind of dissapointing to see that ;(

Re: MUSHROOM DRSSTC

Wow, beautiful build!! Amazing work!

Re: MUSHROOM DRSSTC

That's an awesome coil, it makes me want to dig mine out of the basement and start rolling some more capacitors...

Wow, again, that's an awesome project, zilipoper! Nice results and great setup (on the other hand we do not know anything other from you than amazing projects )

Thank you very much for posting!

Best regards

:(... I guess at least it didn't catch fire or explode and ruin your hard work. Some sort of glitch in the control circuitry?

Re: MUSHROOM DRSSTC
Thomas W, Fri Jul 18 2014, 11:31AM

I would love to know more stats about this.. :)

Max power draw?
Peak Current and so on!
Really quite awesome.

hi
yet there was none of the normal run
hi Goodchild
very pleased to hear
I will try to get on your teslaton

Wow... that sound in your test video, that is some scary shit!

Just the amount of copper in the bridge, great Russian overengineering :)

Are you lucky enough to just find abandoned industrial buildings where power is still on?

Re: MUSHROOM DRSSTC

Amazing construction, love it!

SWEEEEEEEET!! ^______________^
Bridge design - suddenly excellent. Keep it up!

Re: MUSHROOM DRSSTC
zilipoper, Thu Jul 24 2014, 07:49AM

hi
next start MUSHROOM DRSSTC
somewhere around the resonance
current primary 6kA
power input approximately 28 kW
this is not the maximum burst (punches magnifer)

Re: MUSHROOM DRSSTC
Kizmo, Thu Jul 24 2014, 09:29AM

Haha holy crapt thats a lot of power!

Do we have video soon?

Re: MUSHROOM DRSSTC
Mads Barnkob, Thu Jul 24 2014, 09:46AM

Absolutely amazing pictures, the last one is desktop material!

It is not just the coil itself, but the post apocalyptic setting of the abandoned industrial site. Which brings me back to my recent question, where do you get the power from? Is power just on in old buildings?

Re: MUSHROOM DRSSTC
zilipoper, Thu Jul 24 2014, 10:09AM

an abandoned factory tram
there are some people
and there is a very powerful Power Grid
this plant will be demolished soon
need to talk to the guard to be able to run there tesla coils

Re: MUSHROOM DRSSTC
Steve Conner, Thu Jul 24 2014, 11:11AM

Insane! I love it! :D How long is the spark, 4m, 5m, 6 or even more?

Re: MUSHROOM DRSSTC
zrg, Thu Jul 24 2014, 03:45PM

Coil height is about 4m, so the spark is something like that, 4-5m

Re: MUSHROOM DRSSTC
teravolt, Mon Jul 28 2014, 05:38PM

sunning work why did you want to make a magnifier coil vs DRSSTC?

Re: MUSHROOM DRSSTC

Very nice build, must be wound on a surplus missile casing !

Re: MUSHROOM DRSSTC
zilipoper, Fri Aug 01 2014, 12:23PM

Starting the in the field of diesel generator 35kW
generator was very painful
primary current 6 kA

Re: MUSHROOM DRSSTC
zrg, Fri Aug 01 2014, 01:12PM

Nice sparks, but looks like a lot to be optimized still. 6kA with 550V bus voltage should give 8-10 meters of spark, not 5-6m. We've got same spark length with 3.5kA.

Re: MUSHROOM DRSSTC
Steve Conner, Fri Aug 01 2014, 01:23PM

The magnifier configuration might be tricky to optimise. What is the effective coupling of your system? I think you can calculate this as k12 * (L2/(L2+L3)) although I might have missed a square root somewhere.

Re: MUSHROOM DRSSTC
zilipoper, Fri Aug 01 2014, 01:57PM

coupling coefficient of 0.3, we are very poor
necessary to alter magnifer

Re: MUSHROOM DRSSTC
Steve Conner, Fri Aug 01 2014, 05:10PM

So k12 is 0.3? The coupling between primary and secondary?

What are the inductances of your secondary and tertiary coils?

a small video with fire man

That is awesome - what a cool display. Just love the abandoned building setting - so much better than our garages Keep the videos coming.

geee... what kind of of IGBT bricks you use for peak currents 6000 A and how many of them in parallel? Nice monster

Re: MUSHROOM DRSSTC
Mads Barnkob, Sun May 10 2015, 06:37AM


There is pictures of both IGBT type number and number of bricks used in the first post.

Re: MUSHROOM DRSSTC

Good. I see it now when increased size of the pics. Looks like 4 of these

colin heath, Tue Nov 03 2015, 06:59PM

I haven't been in here for long time, but loving this coil!

The magnifier really lends itself to keeping the electronics out of the way and a safer build all round.

I also have a personal love of magnifiers ;)
