Damn !

Just smoked my transistor - shoulda had the neon across it ! Doh !

Oh well, tomorrow is another day, thanks again for your time, patience and encouragement Gyula :)

OK, the transistor gave off smoke (or something did) but it still works !

I connected it all up and the basic concept works.

Sitting the pulsing coil inside the induction coil was giving me a few mVDC.

I'm assuming it's DC now because there is no rotating magnetic field but an expanding/collapsing field ?

Doing it this way is drawing 2 to 5 times as much input power as doing it with the magnet but i think that can be gotten around by having a larger ferrite core in the drive coil as well as having better-suited resistors in place.

Also a different capacitor to give a much faster pulse.

I'm so glad i joined this forum :)

I got thrown off the energetic forum after accusing them of being profiteers, LOL ;+}

Time for sleep.

Try moving a strong neo magnet around near or up against various points on the coils.  You'll likely see a greater output/lower input at some point with the magnet against one.  It does not need to spin for this effect.

Hi e2.

Yes i'd noticed that before, i'm assuming it's my imperfect winding and you get 'hotspots' here and there ?

Even so it always seems to be best dead-centre.

I have no callouts today so will be having  go at building this :

Seperate duty-cycle/frequency control :)

Nice circuit.  Thanks Gary I was just looking for something like this.

Guess what ?

I need help  :D

I'm making this :

http://www.rmcybernetics.com/projects/DIY_Devices/homemade_signal_generator2.htm

and i'm not sure what part of the pot R4 goes to.

Any help greatly appreciated,

Gary.

It goes to any one of the ends, the wiper goes to IC2 inverting Input and the pot's other end goes to R2.  Is that what you asked?

Thanks Gyula.

I still can't get it to work.

Where would the VR1 wiper go ? I have it  going to R1 ?

Hi Gary,

Wiper of VR1 can be connected to any of the other two potmeter legs (between which the pot value is understood).

Putting it otherwise, wiper can go to pin 7 of IC1 (which is R1 indeed) or can go to pin 6-2..etc, any one of these two is good.  This way the pot is not a divider but a simple variable resistor, normally the unused third leg is connected to the wiper.  This insures if the wiper fails, the full resistance of the potmeter can function in a circuit.  The circuit symbol 'arrow' across the resistor body means the resistor is a variable pot.

I've been using the first PWM circuit and it seems like it takes too much input energy and output very little energy.

Maybe a collapsing/expanding mag field isn't as efficient as a moving one.

Back to the old setup, this was an interesting tangent anyway !

Hi Gary,  I think trying to get back power with just a couple coils interacting with each other is a great idea but not in this particular way.  It is really what is the basis of the TPU by Steven Marks as I understand it but there are some definite ways the coils need to be would around each other as well as multiple specific frequencies that need to be pulsed on them.  A bit more complex but if you get it right the power gained can be enormous.  I've read reports of COP over 1000!  If you've read some of the TPU subforum messages you probably know he was using a 9 volt battery and was getting thousands of watts out.  This is why I'm focusing more on that device right now but there is a ton of info to digest on it.  And I'm not even sure anyone has built a successful replica yet.

That sounds interesting.

I'll look through the forums, thanks.

Got some new wire today, a pound of 0.5 mm.

Will wind a new coil and see how much this adds to current-out.

Just waiting for my drill battery to charge !

OK.

Wound a new coil :

SIZE : 25 SWG (0.5 mm)

LENGTH : 286 M

OHM/METER : 0.0871


And ... it sucks :(

Amps are way up but voltage is way down, i don't understand :(

Spent my hard earned cash and a whole day for diddley-squat !
