what happens between a teslacoil the battery the incadescent bulb and the ground

FYI a Q & A from the OUR forum

Hi Luc,

nice demo,   it looks to me though that the both secondaries are nowhere near the same resonance frequency as the primary coil.
You can peak them with the variable caps, but they seem to be at its minimum, so probably you need more inductance on the coils to have them resonate at the 1.14Mhz.

You could try to find out the resonance frequency by using a FG and scope and put them somehow in the same 1.14Mhz range.

Why any other same valued cap does not produce the same results is beyond me, but i can ask my "mystery woman" overhere that, allthough i doubt she is allowed to tell the answer  (http://www.overunityresearch.com/Smileys/Alive/cheesy.gif)

Hi Itsu

Thanks for your post.

Yes, I first test and calibrate the receiver coils with my FG while monitoring power (csr & voltage probes) using scope math. I also have a 3rd probe connected to a sensing coil to measure field strength. 
I tune the inductance and capacitance obviously to achieve resonance but don't stop there. I keep tuning the inductance and capacitance to achieve maximum field strength with minimum power while keeping it at 1.135MHz.
Takes a while to get right but once it's done you'll find the Inductance is around 400uH and the capacitance is around 45pf.

As for why it's working better with the Air Capacitor may be due to the fact I did not use a collector plate antenna on me first 2 test videos.
Test 3 video now have them and maybe now I can use a regular capacitor but I don't think I have anything that small on hand that can handle the voltage.

Hi everyone,

one more video update that solves the need for a Variable Air Capacitor.
I can now make as many as I want for next to no cost.

Hi Luc

fantastic work thank's for sharing all the tips.

I think that for replication, it will be necessary to build the Tinselcoil circuit (modified Steve ward micro sstc ), because with the small tuning antenna on the TC4420, you are showing that the secondary can be totally disconnected from the circuit and directly connected to the ground.

So with this solid state circuit, it seems that you get a kind of "real" Teslacoil, but without the spark gap .

Yes i think you are also showing that  the Tesla transmission will soon  revive

Bravo

PS
if we could get the shematic of the TK's modified Ward's circuit with components value , it would be great

Hi Woopy

Here's the circuit TK used: https://www.stevehv.4hv.org/SSTC6/microSSTCschematic2.JPG

TK says, the main difference is that he did not use the FWB and transformer power supply from mains. He also put in a few extra decoupling capacitors for the 555 and the 4420.
Anyone with the necessary experience to work with this circuit will know where to put those extra caps.
Also, a warning that he cannot be held responsible for any injuries or damage due to the use of this apparatus.

That's all I have

Hi Luc

Yes i already have this circuit, so no special modification

But one of my question is ,

As IMO you have really made a  big change by disconnecting the secondary's  "base" from the circuit by connecting it directly to the ground , can you please check if you also can suppress the 0.001uF 2kv capacitor across the mosfet (better said the  tuning cap between L1 and L2)

And just for fun, in this forum and others ,we are trying to get better knowledge for ourself and sharing with other AT OUR OWN RISK, so nobody can be taken responsible for what he can share on a public forum, (so far there is no contractual selling), so no worry at all.

Thank's

Laurent
