GENERATOR- YOU DO THE IN/OUT POWER MATH

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 :

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