In this videoI show you how to make your own simplified version of the Imhotep Radiant Oscillator.

I have replaced the self-oscillating relay by using the Earth Ground to oscillate my circuit.

At full brightness it consumes 2Amps @ 12Volts, not the best current draw but with some additions and modifications I'm sure we could get this figure down.

  • shouldnt you use a diode or choke to stop be inductive kickback from the primary on ignition coil i would be worried about the transistors destructing

  • yes u probably should, I have a large diode in my new setup that connects to the +ve side of the ignition coil and a diode on the -ve side to run into a secondary battery..

    However if the system is in resonance then it doesn't matter if u have a diode or not, u can feel the HV kickback all over the circuit.

    i can draw sparks from all different parts of the circuit, strange...

    the 2n3055s are pretty solid tho, the 2nd one heats up a bit so i use a heatsink to protect it. how would a choke help?

  • @dodoshlodo i made every timethis circiut exactly as shown in the diagrham but it dident work properly and i had trouble getting the tranny to oscilate but when i did one of them the bottom one got so hot it caused a base emitter short and so i have to keep replaceing the transistor.every time , is your drawing up to date

  • My guess, after reading an article at Yahoo about solar spots and the brochure "CHHSS19Jan2011.pdf", is: GIC currents are probably induced in the coil, and that's why it's just run. While GIC could be a real hazard (10:00 killing a human, but could also be an annoyance muting the VHS band, HAM radio and such), it could as well, in theory at least, work as a power generator, though not effective enough to be used commercially. Just a guess.

  • thanks for this vid. I built it tonight using to circle bulbs and it works. I cannot connect the cap to the base......dies. I can add caps (one wire) a number of places and it helps brightness. The caps seem to be antennas more than a capcitive affect.

    I was getting 550v. Stings!!

  • the reason for the high voltage throughout the circuit is the output of the coil i almost connected to the base (the cfl's and capacitor help a bit but still much more than enough voltage to kill the transistors) the output then should go to the negative side of the coil oh, and the capacitor doesn't block power even if it's polarized

  • try use mjl transistors with heat sink.

  • Yours is sooo much quieter than Imoteps :-) nice setup.

  • the reason when u touch them they get better is because u shout rotate the light in space to find the best result or maximum. then keep the light in that orientation in space.

  • can i buy them from you please?
