This is a Tesla/joule thief hybrid circuit that its inventor claim to produce 90 times the input power! The circuit can be self looped and can provide 1050W of power. from the 1050W only the 11.6W will loop back to supply the joule thief. If you remove the bridge rectifier and the C capacitor you can use the circuit with high frequency AC output. The circuit uses the 2n3055 and a regular bifilar coil `BC` (45+45 turns, 0.5mm wire) to pulse the ferrite core which consist of two large U shape ferrites. The Coils CC1, CC2 and CC3 are not ordinary coils, Are Capacitor/coils combination.

Those coils are no more than two aluminum foils taken from the guts of a large electrolitic capacitor and winded on the ferrite core with a dielectric insulator between them, Plastic film in that case. Each Coil/capacitor has 60 turns of foil pairs. Inductunce should be around 0.53mH and the forming capacitance 48μF for each finished coil.
So each coil/capacitor has four terminal ends and not two as a regular capacitor has. Two at start and two at the end. The circuit use three of these coils for the output. Try to make them as identical as they can be. Capacitors may need to be changed according to the forming capacitance and inductunce of your coils. The two variable capacitors and the variable resistor are needed to tune the circuit to resonate.
The earth connection must be good and must be completely seperate from the house mains earth. Start with low power, put 3 volts at the joule thief and gradualy increase the voltage with the load connected.
Tune first the variable resistor for best output, and then tune the variable capacitors to match the frequencies. Be very carefull while you playing with this unit. You should be expert in high voltage if you decide to experiment with this circuit. If tuned properly, its output can shock you very badly or even kill you.
Hy, I found it very amazing. At university we are trying to construct someting of this application with degenerate parametric amplifier as you of course know very well. We are designing very powerful integrated coil capacitors to increase output power as per Electroboot mk XXI in Nazi war. Would you help us in this adventure? We would construct this app for poor people to get free energy for all of us. My profile is on web: wwe.academia.edu, riccardo tarelli at UNINA (and not only..). Many thanks for your reply, Ric
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
