PLEASE PASS THE LEMONS!

jesus that is a beautiful Tesla coil!
And on a cutting board, no less!

So, now we have a new Tesla pancake named "victor", and a new tesla coil named "lemonade"

Very nice.

It is still unfinished. It needs a spark gap, a capacitor of about 3kv. @hartiberlin recommended 500pf 3000v and I found and sent for 10 of them, a 470pf 3000v at futurlec.com.
Also I still do not understand well how to configure everything together.

I agree with Jeanna, nice work and it looks great.

By the way, looking at the third photo, it seems that is working with the reflection of the desk lamp.
If it were that bright when it work, it would be great, but I think that only will give a small line of blue electricity or high voltage.

OK

So I posted this because I feel it may be important. I have 2 NEO's put together NSNS and then some 26mag wire bifiliar around it. I have it grounded with my power supply and + - to my power supply but the power was never turned on! It was left as is and then the pos/neg were pluged into the citcuit. It started to increase in volts even though it wasn't on....somehow through my power supply even though it was not on. Now I'm aware the power supply's are powerful inductors but this does not happen with a ferrite JT. I wanted to try NEOS because of that new thread with the mag power source. Anyways what do you guys make of it? I'm going to try to hook up a regular JT to it!!!

No initially it is very bright but then the lux goes down as voltage drops.

@stprue

Nice work with a ferrite bar. Or ist it an air coil?

Nice photos!

Jesus

Edit:
I read your post that came before mine, and it says that are 2 neos that interact with the power supply induction and produce voltage.

Thank you!
