Simplest Solid State Tesla Switch
This circuit should be the easiest to tune as well (Reason: when the pulse is at 6V, all transistors should be open switch, so logically, there will never be battery shorts). The pulse voltage source V5 can be replaced by a 555 astable circuit. V6 can be obtained by using an equal voltage divider (two 5K resisters, for example) sharing the same...
Vacuum tube tesla coil (VTTC) using Russian GI-30
A nice and compact setup, that works off-line, directly at 220V, with only a voltage doubler to get the plate voltage up to 560V DC. I don`t need to go into details explaining this circuit, it is a simple Armstrong oscillator, using the feedback coil L4. Here is a great tutorial detailing all the basic knowledge and know-hows behind a VTTC. My...

The coil has been added a few extra turns, so I had to find a way to improve the insulation. I opted for epoxy, with some extra quantity added over the soldering:
Miniature Vacuum Tube Tesla Coil
Vacuum tube tesla coils operate in a continuous wave mode of operation, continuously providing energy to the tesla coil secondary. As a result, the output is primarily determined by how much power the vacuum tube can process. The spark discharge and operation of these coils is quite different from disruptive coils. If a D. C. voltage is used to...

This coil operates from 12V or 24V SLA batteries. A pair of car ignition coils are used to provide around 20kV for charging the capacitor bank. The ignition coils are driven by a variable frequency square wave from a 555 timing chip and four large transistors (2N3055). Using Butane gas and air, a blue flame can be used as an interesting discharge

Tesla transformer Project
The project Thor was started at the High Voltage Institute of HUT (Helsinki University of Technology) on January 1999. Dr. Martti Aro is in charge of project supervision and Marco Denicolai of project development and implementation. Within this project a Tesla resonance transformer is analyzed, designed and built for study and research. This paper
SOLID STATE TESLA COIL
A TV flyback transformer can double as a low-power Tesla coil. The Tesla circuit consists of a pulse generator, a driver circuit, and a high-voltage transformer. Resistors R1 and R2 determine the time duration that the output at pin 3 is off, while R3 and R4 along with R1 and R2 determine the ON time. Inductor L1 and regulator IC2 provide a clean,

The large coil has an inductance of about 2800 mH, with a self-capacitance of about 20 pF. One end of the coil should be earth grounded. Put a metal ball (a drawer pull knob or doorknob) at the other end....

In this section, the previous coils were dismantled and a new larger coil, with a secondary over 6 inches, was redesigned and constructed for maximum efficiency at a power if about 1, 440 watts. The tesla coil project is aimed mainly at the scientific and Tesla coil
LiquidFire Teslacoil Pages
Every cheap energy-saving lamp has a self-resonant voltage inverter inside. They are designed for low-power operation up to a few watts. Why don`t scale up the whole thing and replace the resonance circuit for generating the needed lamp voltage with the tuned primary of a double-resonant solid state tesla coil (DRSSTC) T
Tesla Coil Design
The goal is to repeat the demonstrations showing that the electrical field energy developed by a well-designed Tesla coil transmitter can be detected by a sensitive, well-tuned Tesla coil receiver placed at a distance exceeding a few wavelengths. The present investigations involve scaled-down versions of Tesla`s wireless system such might be assem
tesla coils and high voltage
Most people believe spark gap Tesla Coils can only be operated from high voltages - typically 4 - 15kV or more. But some unusual experiments can be made with as little as 240V - directly. Outside of very low frequency Pancake Coils, there is little practical applications for using such low voltages. But it is interesting that the concept works....

Ultrasonic distance finder circuit
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 measured. There are three main categories of distance measurement methods in use: a) By...
Simple Metal detector circuit with CD4030
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 find something potentially valuable, hidden a few centimeters below the soil. So many...
Fully automatic watering circuit for flower pots
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 circuit comes as a solution to this problem. Depending on humidity of the pot at...

Sub-Harmonic Bass Converter for Electric Guitars
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, such as filtering or distortion. Instead, a frequency division system produces outputs...
Echo Depth Sounding Sonar for Boats
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 calibration of the rope. This arrangement still exists in some yachts. The big...
