This video is based on Dr Stifflers Sec exciter.
In this experiment I show a way of tuning an exciter using a magnet positioned on a fixed inductor.If you postion the magnet just right you can set up a secondary oscillation.

  • jonny i put in like 15 hours (at least) on this circuit LOL but man oh man, I hit it. Check it out. This circuit is like toying with magic, I love it. Thanks.

  • Hi Kyle.I have watched your journey with this circuit and i am glad it was you who tried it as you have to tease the results out of it and that takes patience.

    You show some amazing results in your vids,the plasma was particulary awsome as i have never seen that before,even from Dr Stiffler so your voyage of discovery has found new territory and i am sure there are more suprises to come.Thanks for sharing your results.Jonny.

  • Pretty nice output light for around 450 MilliWatts of input power.

    Why does the input current go up, if you go a bit further away from the L3

    coil with the fl tube ? Is there then the resonance point location where it

    draws the most input current ?

    Many thanks.

    Regards, Stefan.

  • Hi Stefan.The sec circuit is a very tunable circuit regarding current draw and performance in its standard form but adding the magnetic tuning makes things a lot more interesting and you can pretty much get any kind of combination of circuit operation you want from high output close to the coil and dropping off as you move away to low output near the coil and getting stronger as you move away.My body capasitance has a big effect on the circuit as well and can detune or

  • tune the circuit and this is what is happening when you see the current draw increase as i move the cfl away from the coil as the circuit has come into resonance.Hope this helps.Jonny.

  • Hi blackmesa25.When you first see the wireless effects of these exciter circuits it does seem like magic and if they used circuits like these in school lessons then i am sure more people would go into electronics as a career or hobby.Thanks for your interest.Jonny.

  • @freeenergynews I'm not qualified to say Stefan, and I don't claim to be, but i put almost 22 hours in on this circuit. For the first 6 hours about 75 mA was the best i could do, but then I kept repositioning the coil, the fluoro, a virtual ground, and it's almost opposite as you say, there exists a point where at max light, perfect capacitance, your draw goes REAL low. Mine, low 20's (mA) almost as if the field sees the tube as a negative resistor. i dunno. Amazing!

  • @jonnydavro I've been wanting to get one from The Dr. but I am in Canada, so i will have to arrange something. Thanks for sharing this demo it is very fascinating indeed.

  • interesting thing is you do't actually need an L3 coil.You can get hv from just the L1 enough to light a neon but not much radiated rf but very useful for lighting leds.Why don't you try this circuit kyle or even better,try and get a pre built board from the Dr.He only sells them in the US but i think it would probably be a very interesting buy considering that he is not asking much for them.Thanks.Jonny.

  • Hi Kyle.Yes the L3 directly of the L1 is present in all the Dr Stiffler sec's i have seen from his early 15-3 to his 18 series although the size of the L3 has gotten bigger in his latter circuits,it was a 22uh choke in his first 15-3 and i never had much luck with that with regards to lighting cfl's but it would light neons and leds for fun.The difference between the slayer and the sec is the coil collapse of L1 is direct through the L3 and return path is the air and another

  • Increasing the range as adding the magnet has created what looks like to me,two seperate oscillators running together at the same time.It would be interesting to see a scope shot.The pulsing can be adjusted from a slow strobe to a very fast pulse which is hard to detect with the eye but its something else to play with :-).

    I will try raising the setup of the worktop and see if it works better.Thanks Slider.Jonny.
