Particle induced air ionization

Alpha particles are very energetic little buggers. In fact, energies of 20MeV per particle are not uncommon. While this makes them incredibly dangerous if you happen to ingest…

Nuclear Bomb Detector

Here is what I can best describe as a cold war era nuclear bomb detector. Whether or not such a device is legal to own is a matter…

Geiger-Muller Tubes

By far the most common radiation detector, the Geiger-Müller tube itself is nothing more than a highly modified neon lamp. Its method of operation is rather simple. The GM…

Radiation Safety

If you intend to copy my x-ray experiments, let’s be safe now, shall we? Nonionizing radiation, the stuff of microwave, infrared and visible light doesn’t have the energy…

Coolidge Tubes

Invented in 1913 by William D. Coolidge, the Coolidge tube is by far the most popular method used to generate x-rays. Essentially it’s just a thermionic diode, but…

Wire Loss Calculator

Electricity is useless without a way to move it around, so in order to accomplish that task people invented the wire. A wire is nothing more than a conductor…

X-Ray Transformers

Before small cockroft walton multipliers became inexpensive, x-ray machines tended to use large iron transformers. These are the highest voltage transformers you’ll likely ever come across, with even a small…

Voltage Multipliers

Transformers are not the only way one can boost voltage; another method to the madness is a Cockroft-Walton multiplier, or thes the Villard Cascade depending on your favorite…

Flyback Transformers

Also referred to a Line Output Transformer, the flyback transformer is a high frequency, high voltage transformer most often used to power cathode ray tubes. Flybacks are capable…

ZVS (Mazilli) Driver

A “ZVS driver” is a mazilli oscillator; a very simple circuit that can oscillate a large amount of power with about 90% efficiency. To the right exists a…

Marx Generators

Marx generators are the simplest voltage multipliers out there, as they contain nothing but capacitors, wire and resistors. Below is a schematic of a marx generator and as…

Microwave Transformers

The microwave oven transformer is possibly one of the simplest methods of making some big high voltage arcs, mainly because they are robust, cheap, and easy to hook…

Neon Sign Transformers

Neon sign transformers are transformers used to power neon signs. Typically outputting 30mA at 4 to 15kV a neon sign transformer is a great toy to have if…
