Finn,

Looks good what happens if the left coil wants to arc to ground instead of the right coil?

Take a look at these twins:

1228340283 205 FT58545 Twingut

It is a twin, viewed in it`s faraday cage half shell, before it is closed, at which point it looks like this:

1228340551 205 FT58545 Twinfire

The distance between spheres is 500mm, distance from anti corona ring to cage is 130mm.
I use these coils to judge the probability of a strike outside the strong field from +xxxxxxV to -xxxxxxV
Well, that probability is a very small one. You should all build a twin coil system, to enjoy the pleasure of having superiour controll of the discharge path. wink


The coil shown is one in a series of 2 that I built for the Danfoss Universe Theme Park, along with the big one:



1228340907 205 FT58545 Bigone

The big one, by the way, is equipped with the novel remotely (by the show controller) operated preakout points, enabling a preprogrammed sequence of lightning bolts, each thrown in 1 of 6 directions spaced 30 degrees apart. shades

Cheers, Finn Hammer

And yes, All that gold _is_ gold, plated on copper.

Finn: I take it that the coils will be bipolar and therefore arc to each other. Are you installing the primaries inside the secondaries? I assume this is the case otherwise primaries arcing would be a problem, although there seems to be enough distance there for outer primaries perhaps? Nice work.

Chris: Be a duck man and let it wash, you the man! Where would we be without you? No eyecandy that's for sure.

Tom: Triple posts are highly illegal and punishable by death...I think...I could be wrong on that one.

Edit: Wow Finn, that is some really nice work!! More please?

Good day guys

Chris - don't buy what they are saying.

You have been helping HV members for years (including me) - for wich I REALLY THANK YOU smile

Finn - that thing is AMAZING amazed

Hmmmm - can you implement something to look like a spark plug on the torroids ?


Cheers

Ooo, Finn is pimping the Danfoss Universe project! :D

I don't know what drives the twins, but I did the driver circuit and firmware for the big coil: it's very similar to my OLTC2. And the whole thing meets European EMC regulations.

Finn, how are you going to wind the secondaries on your coil? Or to paraphrase Quentin Tarantino, "It's not a Tesla coil baby, it's a chopper"

Dr. Spark, if you really want to impress me, you should mount a DRSSTC in your sidecar and fire it up at a bike show wink

That's pretty cool looking. I like all the bling.
Actually, now that I think about it you have a good point. The arcs primary goal is to reach the opposite end of the secondary not ground. Found this out by having a coil upside down close to ground. The arc still went towards the base even though it was further away.


Yes I know I just double posted again but the second post was actually on topic. They're better off separate.

Okay, I've deleted one post to attempt to keep things civil. Let's keep it on topic. Any further personal discourse can happen in PMs, or better yet, just forget the whole thing and let it be water under the bridge.

With a bit of deeper thinking this expression might sound both pretty funny and destructive :D

Nice concept, wonder how the finished version will look like. By the way, how are you going to trigger this one - by the same driver for both coils, via a simultanious firing mode or fire them off independantly?
