Re "isolation" of the signal source: it must have a common ground with the power section, yes? Just the signal input to the 100R base resistor of the first transistor isn't going to do anything unless the ground of the signal source is connected to the emitter somehow, I think, by connecting to the common ground at the emitter of the second transistor.

Yes, exactly.

The grounds between the 9V and 12V supplies will be commoned. Very simply put, he either needs to disconnect the FG output from Q1, OR remove the 9V source from the FG. Either one will remove the "effect" he is seeing.

I made reference to the low powered ts3001 because they are free. It  outputs a perfect half duty square wave and is an adjustable PWM  in that range . The designer of the Ultralow powered chip ts3001 gave those specs  it operates on 0.8 to 1 volts at 1ua . I got three and will try it . otherwise just build the one that is referenced which is also cheap to build .

It operates on 0.9 to 1.8V, and at 1uA @ 25kHz operation.

If you want to drive that circuit, you will need to run the TS3001 off the full 1.8V.

Don't expect the current to remain at 1uA draw. Once you start driving that transistor, the current consumption will increase dramatically.

Mine runs fine at 1 volt and varied without any notice of current that i can measure but if it does it isn't as much as a 555 and lm393 so it is almost self powered it self . I have it on a 100uf cap with a germanium diode pair hooked to a ground and ariel core and  it produces a stable  square wave  and has two outputs so its a full square wave if you use the two together .it appears to be 1 volt pp give or take a few millivolts and will keep going even if i ground out one of the outputs with a resistor load  . I will try to see if i can even detect any increase as it is very hard to see 1ua on any of my meters but it will run on nearly nothing .i can see the square wave form varied up to 25 khz . at less than 0.9 volts it still runs but then i see the frequency drift and it will run to .6 v then stops.    . We only need 1 khz half cycle though Highly stable little chip here. . Get one free and check it out . It is supposed to the the most efficient chipped pwm signal  out there . I got several of them and several of their energy harvesting project ops demo boards and want to combine a set(ts1001,1002,1004) to harvest and store the electricity for another project. .. I do have  circuits that runs off of a half a ua posted in Jule thief and it indeed works from the electricity in your hands holding dissimilar metals  lighting an led . very efficient and i use them testing crystal cells . i got one cell made from a tiny 22 bullet that put out 1ua max# 1.2 volts dry and lights it up enough to read by and it also powers this ts3001.  Tk thanked  me on his replication of my circuit and had no idea you can run an led from the base/emitter of a transistor at so low a current or voltage 0.395vdc he mentioned that he gets some really high spikes that are ODD and made a cool video of the effects he gets running it with a lab power supply . Mine is just showing the bullit battery powering the circuit . They are easy to make.

I understand isolation and common grounds . I have also see floating grounds and sig gens doign there thing ,

I don't know if he has his Donald Smith coil hooked to this in any way but if he does the air could be his Ground  plane on the Sg. The Video is after all named Don Smith Device project, from his successive test with it .

a bit off topic this is a new age of nano powered chips.   TS1001 0.8V/0.6µA op amp from Touchstone Semiconductor, makes a sub-1V supply current sense amplifier possible. This discrete circuit operates from as low as 0.8V and draws 860nA at no load while providing a 0-500mV output for measured currents of 0-100mA,

very cool demo boards .

I hope we hear from mr Clean soon . I got my toroids and transistors  ready !

here is the concept of the coils configuration from Thain who for some reason stopped research and deleted most of his work. i wonder why when it was brilliant work.

hi everyone, i am not using any tricks, but im having a hard time reproducing this myself, so i hope not to cause too much frustration, but here is how i have it wired...

correct that it needs the 9v in FG, or nothing is telling the transistor to do anything. and freq being critical here i believe.
but the signal gen cannot run the system alone with out a battery pulse.
like i said tho, if it wont work dont spend to much time on it.
however the Bitoroid i feel is very much the right direction
