This blog was home to some exciting high voltage related experiments already. While my time for hobbies is becoming increasingly limited, I recently got a HV-1 high voltage inverter KIT and decided to show it here. It’s a one transistor oscillator, with a feedback coil in a compact high voltage transformer. It’s identical to the first high voltage inverter I’ve built, except for the flyback transformer. Even with its tiny…
A robust regulated high voltage supply, an inverter (boost converter / step-up) 3V to 400V for portable applications.
Build a battery operated, compact high voltage inverter for Nixie tubes, neon bulbs or Geiger counters.
I met some great people today, and I also got a wonderful device for my ongoing experiments as a gift: The UT50 Scintillation probe, manufactured by SC ICPM SA Romania. It features a huge NaI(TL) crystal, with a diameter of 5.5cm and 5.5cm length. The photomultiplier is a British EMI9656KB and the entire device is encapsulated in an aluminum modular cylinder of no more than 24cm total length and 1270g…
A hydrogen thyratron is a device capable of switching big amounts of energy. The major advantage over other thyratrons is that the deionization time is reduced by using the hydrogen gas, generated in a small reservoir inside the tube, from a metallic Hydride.
Protect your tent’s perimeter from bears, when in the wild. A 20KV pulse generator will inflict painful shocks to anyone touching the perimeter electric fence wire. Not lethal, but very painful, enough to put unwanted visitors on the run.
A CW High voltage supply that produces up to 140000 volts (140KV) . Simple, clean design, without oil, but with high quality multipliers.
Build a disc shaped flyback secondary. A robust new design, that will do a great job in your High Voltage projects.
An article on Thyratrons and a film showing three energized tubes : the 714, the 309/FG17 and the ELC1B.
My first attempt in building an inertial electrostatic confinement device . It didn’t work.
Build a Ion Thruster using light materials and power it using a 50KV supply to see another kind of propulsion.
Using a high voltage 1GOhm resistor to built a DIY high voltage probe, to measure voltages up to 55KV with a normal multimeter, by scaling the voltage down by 1/1000.
A scintillation probe enclosing the regulated high voltage supply, the signal amplifier, the photomultiplier and the scintillation crystal (NaI). Building a DIY counter for a NaI Scintillation probe. AtMega8 and a bluetooth module for wireless data output. A cheap and easy to build homemade dosimeter with applications in spectroscopy.
Build a Half Wave Villard Cascade of 28 Stages. That means for 10KV in you get (in theory) 280KV out! An incredible voltage, perfect for physics experiments.
EM-11 is a magic eye tube, used in old radios for tunning. See some schematics on how to use this tube, for some green, fluorescent effects!
An article on various high voltage sources. Includes schematics, construction details, high resolution images and videos.
How to make a high voltage capacitor in a few steps. See a video with my 19nF/10kV capacitor, with under 1$ cost.
