Group: Moderator Hero Member Posts: 4159	It seems that with the FG driving the circuit, i have a higher tank amplitude then without the FG (1.4KVpp versus 960Vpp) which i expected to be the other way around. So i scoped the input to the gate driver (at the junction of the switch S1 and the 50 Ohm resistor R1) see below diagram. Below are the 2 situations, first screenshot with the FG connected, second screenshot without the FG connected. Yellow is the tank voltage (probe not connected) Purple is the input signal (S1 - R1). So allthough we have a higher input signal with the FG disconnected, the tank voltage is lower (13.5Vpp versus 7Vpp). Could it be that the rise time of the input signal is the problem/cause?

Group: Tech Wizard Hero Member Posts: 1194	Hi Itsu, Try to reduce the 100 kOhm R2 resistor to as low as possible so that the RF voltage amplitude (pink channel) could be reduced towards the 7 Vpp or so value. Also if you have a few 1N4148 diodes, make a series string from say 5 or 6 and clamp the RF voltage across R2 and see whether it improves things. Gyula

Group: Moderator Hero Member Posts: 4159	Thanks Gyula, glad to see you here still offering your knowledge I will see if i can follow your suggestions, the little gate driver print was not meant to have so many changes, so i will try a breadboard approach first. Itsu

Group: Moderator Hero Member Posts: 4159	Got some additional comments to use different diodes or a hysteresis amplifier or Schmitt Trigger inverter stage (2) to shape up the input signal but it seems the IXDD614 gate driver i use already has a Schmitt Trigger input. So i will go for using Gyula his suggestions and/or changing the diodes to 1n4148/1n914 types, or perhaps Schottky 1n5819 or similar. Itsu

Group: Moderator Hero Member Posts: 4159	Gyula, i tried severall resistors parallel to R2, but even a 10K parallel still leaves about 12Vpp on the pink channel (input signal, no FG). But adding 6x 1N4148 across this R2 (so now about 10K) gives the result as shown in the screenshot. Tank amplitude (yellow) slightly lower then with FG (1.3KV versus 1.4KV) and the input signal now clamped to 3.8V (6x 0.633V), see pink vertical lines delta data, top right corner. So i guess much more acceptable. Itsu ------------------------ Itsu's workbench / placeholder. gyula suggestion.png (31.16 kB, 640x600 - viewed 576 times.)

Group: Moderator Hero Member Posts: 4159	Yes, i am pleased too as now i can use this stable autoresonance circuit to investigate further on the only anomaly seen during my testing, which was the 2 horizontal satellite coils getting their leds brighter when inserting another satellite coil vertically inbetween the Big coil and these horizontal coils. Could this be the sympathetic resonance being mentioned?? I cannot link to my post on OU.com directly somehow, so use this link to get to the top of the page, then a few posts down (post #797 today): https://overunity.com/17491/confirmation-of-ou-devices-and-claims/975/ My linked video there showing the effect here: https://www.youtube.com/watch?v=-9dLj5MrAHY A possible explanation done by partzman here: https://overunity.com/17491/confirmation-of-ou-devices-and-claims/msg536448/#msg536448 Itsu « Last Edit: 2019-07-24, 21:09:34 by Itsu »

Group: Tech Wizard Hero Member Posts: 1194	Hi Itsu, Yes, by making the TX coil autoresonating while loaded coils are being coupled to it will make tests easier (number of variables is reduced). With small ferrite core pieces now the satellite coils can be tuned much easier to the actual TX frequency where always the maximum energy is radiated. What pm mentioned with "maintaning the proper dot relationship" is also a good step, to be investigated. Your question on sympathetic resonance I think could be better answered by the use of several (more than 3) RX coils, all in mutual coupling with each other, so what we see in your linked video is not likely the sympathetic resonance case yet: it may be a 'mutual resonance pulling' between the 3 coupled RX coils to a frequency closer to the TX coil frequency (which may have also been pulled away just a little). I also noticed that in the page you linked to, the direct links of the first 5 posts in page 66 directs to the top of page 65, from posts after the 5th posts the direct links are already ok. Likely either a forum software 'glitch' or a few posts have been deleted. Gyula

Further north,46-50c is quite common. I guess if your use to cooler weather,then 40C would be very hot. Brad --------------------------- Never let your schooling get in the way of your education.

Group: Guest	Guys: Wow, I have never had such a nice welcome, thanks to all for such a nice reception here. There may be some interesting information concerning isolating the input source from the output load, and three coil set up by Dr. Stiffler. There may be some relation to what is going on here, with the current type of replication being worked on. https://youtu.be/lxRbckLedjU

Each receiving coil is replicating field and re-transmitting waves so the transmitting coil is also receiving feedback. As you have base setup already you may explore D. Smith idea and see what you can get in similar setup like he did with 1 trasmitter and 3 receiver coils. The results would be interesting to see. P.S> Welcome to the forum NickZ! Cheers!

Few things instantly in my mind - what happens if you do in pure Tesla's way of driving transmitter? When the primary coil input is driven by spikes (duty cycle less than 10%, the driving singal is interrupted) and creating resonance between top load of secondary (missing in your setup) and the ground line (no wave nodes/antinodes in middle of secondary coil). By idea the input power should drop while maintaining peak reactive power in resonance on the secondary coil. And when reaching certain secondary voltage the top load should start interacting with ions in air. Just need to be not too much (when it starts arcing).

Group: Moderator Hero Member Posts: 4159	T1000, Yes, i think you missed that as the setup you now describe is different from what i was trying to replicate. There is no primary on the transmitter coil and also no top load on the secondary (indeed missing). Could be a nice new project, but at the moment i have some loose ends on this present replication which i want to tie up first. Itsu

Group: Administrator Hero Member Posts: 3217 It's not as complicated as it may seem...	Itsu, I finally had a chance to go check your video and setup for RF's "device" verification. Wow, you really went all out! Very well done as usual. It is a pity that there wasn't any acknowledgement from RF himself, until I guess much later. And apparently Aking, the one supporter of Rick's missed it too! Anyway, you put a lot of work into that replication, and blows away everything Rick has shown thus far. Well done. I know you're tying up loose ends atm, so carry on maestro. --------------------------- "Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe.
