Slightly OT but wouldn't it be better to plate topload with Ag (silver). It is the most conductive element and I have to think it would be cheaper to plate with than gold. Maybe you chose gold because it doesn't tarnish? Anyway awesome work, very jealous! Dennis
The gold topload plating was for *looks* only. The lack of tarnish was the main objective, but the associated exclusivism og **gold!** played a part too.

Henry called me this morning as stated “Have you seen Finn’s killer coil?†It is the talk in Arizona for sure; can you put in suit case and bring to the Thon? Hee hee
Great work sir, your work is always Top Dog!
Thank you for your kind words.

Only issue is you need RED LEDs under topload flashing with pulses, and a little smoke machine puffing smoke, hee hee.
Rgs, Ch
You are right, of course. How can I argue against the master of the LED's. And so many other things. Only problem getting power @ low voltage up there. Perhaps a couple of turns up there, and a led would do the trick? On second thought, with 600V/turn, perhaps just make a necklace of plenty many leds around the coil up under the topload.... Damn, the coil is dismantled again already....But I'l have to try that sometime.

Just back from Paris, where I mounted the V-Twin into an installation by Swiss artist Roman Signer. This is art to those that think so. Thank you to Kurt Schraner for referring Roman and Jurg to me for this job. I`l just give you'all some eye candy of the coil, at the moment drawing a pesky waveform, for 7.5 seconds at 2minute intervals, 12 hours per day for the next 70 days, starting 12-02-09, for 52.5 hours of total run time during the exhibition. The guards are already getting nervous ticks just before each burst, so I fear vandalism more than dielectric breakdown or bonding wire fatigue (those CM600's are pulsed @ 2660Apeak). This 1st. picture captures the impression that is available to the average joe, viewing the exhibition.
The rest are for you all, the invited l33t. =:-)
If all goes well, there will be a nice list of usefull performance parameters for the next generation of BRISG coils.

Wow that looks great! I can't help but wonder what's with the umbrellas some sort of metaphor? I noticed the whole thing now site with the two secondaries symmetrical.

I like it. I think it looks really sinister with the sparks in the space between two hovering black umbrellas! I'm not surprised that is spooks the security staff!
From a scientific point of view it's cool how the toroids and the feed wires don't break out, only the tips of the two umbrellas. It's also good that the HV doesn't track over the surface of the cords up to the roof that the umbrellas are hanging from.

They were able to handle the looks allright. But the sound @100dB....

This is a function of pouring excessive amounts of power into the arc. During inithial tests, the nylon fishing line would melt due to corona tracking. When power was increased, resistance of the arc channel dropped, so that it became the preferred path of discharge. At least that`s how I see it. The museum staff requested that I find out how to make the display quieter, but no matter what I did: pulse the arc with short pulses, but still connecting: Tracking was the immediate result, and umbrella was hanging in one cord.
