You need to find a reliable full bridge driver to drive your flyback transformer? Well, This is your final stop. There are many flyback drivers schematics out there, but most of them will not last for long. It is common known that famous ZVS invented by.... -
The Tesla coil described here can.generate 25,000 V. So, even though the output current is low, be very careful! The main component is a flyback transformer from a discarded TV. A new primary windin_g is needed. Begin by winding 5 turns of #18 wire on the.... -
Power is fed to transformer Tl, a small neon-sign transformer, which steps the voltage up to about 3000 Vac. The stepped-up output of Tl is fed through L1 and L2 and across Cl, causing the capacitor to charge until enough power is stored in the unit to.... -
Here's something that has always bugged me: light waves are about 5000 Angstroms in wavelength, while atoms are more like 1 Angstrom across. Atoms are thousands of times smaller than light waves, yet atoms obviously interact very strongly with light. How can.... -
I built two secondary coils: Small coil D25.4/H119 (Diameter=25.4mm and Height=119mm) and Medium coil D73/H228. I experimented with the spark gap, and observed that a series spark gap is better in terms of power handling, noise, and spark discharge length..... -
Plasma Globes were invented by Nikola Tesla some time before 1892. Glass-enclosed Tesla coil terminals containing low-pressure gases were part of his effort to develop a new source of lighting not covered by the Edison patents. The same device became an art.... -
My major project over the last few months has been the construction of a small Tesla coil, having wanted to make one for many years now. My first experience was at a demo day at UNSW over a decade ago, and since then I`ve always had a bit of a fascination.... -
This is a fun and useful circuit for demonstrating high frequency high voltge. It can produce up to about 30KV, depending on the transformer used. It is cheap and easy to make, thanks to the standard TV flyback transformer used. It can power LASERS (although.... -
This is the Tesla Coil circuit diagram with the detailed explanation of its working principles. The electronic circuit simulator helps you to design the Tesla Coil circuit and to simulate it online for better understanding.. -
VTTC (Vacuum tube tesla coil) is a Tesla coil with vacuum tubes as a switch. I used self-oscillating circuit with two russian (soviet) tubes GU-81M connected in parallel. The source of high voltage are two MOTs (Microwave oven transformers) connected in.... -
Because of the high voltages found in a Charge & Primary sections it seems natural to look for cable with high voltage ratings, such as neon sign cable, medical X-ray equipment cable & car engine spark plug leads. The first two would be fine for connecting.... -
In this picture is everything you will need to make a self running power supply. The input is a 12vdc 7ah lead acid or gel cell battery (not shown). The input goes to a 12vdc to 120vac inverter of about 200 watts more or less, it is not critical as long as.... -
The principle is that there is a certain parasite capacitance between coil windings, which stores a certain amount of energy. By winding the coil bifilar, you get substantial bigger voltage differences between adjacent windings and therefore more energy is.... -
A full foot long arc and get to more then 1million volts eventually. I have finally built a REAL Tesla coil that operates via an arc and capacitor combination. Not just a flyback or transformer setup in series. It was not as difficult as I thought it might.... -
This circuit was designed to not fry the 555 timer, this is because I noticed that having the ignition coil share a high voltage contact with a power connector made somewhat high voltages go back and into the 555 timer, thus frying it (I went through about 7.... -
This is a modified version of the first SSTC I built, the Kaizer SSTC I. It uses the same secondary, topload and driver board. New things is a full bridge of IRFP460 MOSFETs, audio modulation, shielded drivers and a new casing. I took apart a 19 ³ LCD.... -
This page contains tesla coil measurements using signal generators, frequency counters, oscilloscope etc.... -
A PFC capacitor on the mains side can act as "current limiting" to some extent. Otherwise, use resistive or additional inductive ballast (a MOT in series with shorted secondary winding). Power factor correction (PFC) shifts the VA rating of the transformer.... -
An electromagnetic generator without moving parts includes a permanent magnet and a magnetic core including first and second magnetic paths. A first input coil and a first output coil extend around portions of the first magnetic path, while a second input.... -
One spark gap (in a first version these were just copper wires bent into a ring at the end to suppress corona, the current design is somewhat more sophisticated and uses spherical electrodes), It produces a 300kV output pulse with a discharge energy of 36.... -
This is an electrical propulsion method with no moving parts which applies to any conductive fluid including water, liquid metal or plasma. Here I am demonstrating the principle with water. Essentially two electrodes in water have a current passed between.... -
There are two schematic diagrams showing a series and a parallel circuit that Tesla could have used. The tubes used were a common 70L7GT Half Wave Rectifer that believe it or notare still available today. I know all of you want to see this site but be.... -

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.....
