Akula0083 30 Watt Self Running Generator.

This circuit is nothing special.  You can achieve the same thing using signal generators. See WESLY experiments on his 1kw Yoke device. ...

I Bealive that here no 1 kw. I see that video and that lamp Weshley say in full brightness, but i see, that it light on about 5 procents of it power. So I not bealive, that they get free energy. Maybe get, but wery small amout of it.

This circuit is nothing special.  You can achieve the same thing using signal generators. See WESLY experiments on his 1kw Yoke device. All the answers fully disclosed now couple of years at least public domain.  Instead of push pull discrete fet driver use dedicated IC fet driver instead. A full H bridge design is superior to get max power and symmetry into driver stage.  If you have RF sig gens you can make tests using these with a wideband PA fet amplifier as a core driver.

This is a ferrite banging device requires ferrite yoke, rings, cores, slugs or anything else to forced into a piezo electric state where ferrite becomes a "SQUEELING  PIG!  You need to drive the core into full magnetic saturation then make sure the ferrite is gapped to make ASYMETRIC transformer.  Use a paper shim.  Be careful as you must drive the ferrite hard couple of amps 20 or 30 watts or more. You will hear sweet spot when tuned when ferrite goes critical! CAUTION! FERRITE CORES CAN EXPLODE UNDER SUCH CONDITIONS. Cores will get hot.  Ferrite will burst with harmonics in this state going into lots of Mhz.  Panasonic microwave oven cores are good can be driven with couple hundred watts. When you can hear the cores SCREAM you are then in the ballpark of going OU.  The load must be matched. Impeadance not too low or too high.   Random tuning and tickling these cores with milliwats or shit driver will get you no where.  You dont have to use LED lights.  Halogen can work but of course LED is of course MUCH brighter.

The only real design work is finding the best coil winding solution to match YOUR cores to YOUR load. Everyone will be different.

Good post. I've experimented 'bashing' different types of ferrite in the past using a PWM 150A, full H-Bridge motor controller modified from a fixed 25KHz to variable frequency control. However, be very careful as this type of experimentation can be dangerous! Wear eye protection and use a polycarbonate screen between you and the DUT. Getting conclusive results is difficult. Bolt is correct IMO when he says that tickling your ferrite will lead nowhere.

Don't forget an appropriately rated fuse, especially if powered directly from a battery.

A 3 amp breaker or inline fuse is a good idea.  I calculate 3 amps.. I think correct.

Maybe something like this..

Second video from the same author was published. He has intergrated the circuit in the portable LED Spotlight. He says that this circuit works ONLY with LEDs. He also shows how the core of the transformer must look like.

Here is the 12v 10w flood light used in the second video.  I wish he would have shown inside black box to show no battery.
