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.

Pls. accept my apology for not mentioning off hand. This project had never come true without your groundbreaking brick OLTC.

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"

The coils fit inside the tubes you see. The "cylinders" are 220mmØ inside and the coils are 200mmØ outside.

Btw, the primary coils are now finished rolled, and first acid bath. Material 2.5mm by 45mm.
Resonant with 10µF @ 44kHz

Rather low Q in primary, which is good and bad. Good for this coil, because it is going to drive external loads, so easier to tune.

Also notice nifty litle trigger SIDAC board on Brick

Trigger pulse is looped trough transformer of both bricks, for dual bipolar drive.

Cheers, Finn Hammer

 		I cant stop thinking about the gold toploads you have. I'm thinking of having one of the toroids i got from Daniel gold plated now. No more polishing!

Why not? It is not_that_ expensive. I think mine cost around 300US to have gold plated. Pretty cool if there is a budget.

 		I thought it was just gold color. Does the gold plating actually help alot?

 		Yes the one place I looked didn't have a listed price. 300 is sort of a lot for a small 8 inch toroid. If they could plate my 20inch aluminum for 300 i would totally go for that.

 		All,

The primary circuit of the BRISG tends toward the complex, maby that`s why it never caught on.
Here you see the parts before assy`.


1229276647 205 FT58545 Primaryparts


And this is what they look like when they are bolted together.
Quite a lot of tin smithin`and plastic weldin`.


1229276668 205 FT58545 Priassy1


Of course, mounting the whole kaboodle inside a cylinder, and aspiring ability to adjust coupling doesn`t simplify things....


1229276694 205 FT58545 Crankguts


And here it is: The primary coil gleefully awaiting the insertion of the secondary....

 		I love it! I am concerned about your assembly being held up by Nylon though. I'd probably go for some FRP screws.

Thanks!.
Housing is PVC, bolts are stainless, so I don`t expect any interference.

What`s wrong with Nylon, what is FRP?

 		The nylon is just holding the primary. I think it'll be fine. Looks awesome BTW.
