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…
Fixing a CDV700 dosimeter can be difficult because original replacement components are not an easy find.
A story of making a DIY Digital Geiger counter circuit, that can be used with several tubes. Add an enc28j60 Ethernet module and use the data to create graphs available online!
A Longitudinal Excitation Nitrogen Laser design, using a fridge pump for vacuum and N2 from air as lasing medium.
Using a hydrogen Thyratron tube to switch a Tesla Coil. The Thyratron tube replaces the noisy spark gap.
A very customizable pulse generator built using three 555 timers, to control a relaxation oscillator hydrogen thyratron.
My DIY PFN for a relaxation oscillator using a hydrogen thyratron.
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 vacuum tube tesla coil built around the Russian tetrode GI-30. My first VTTC and my first vacuum tube circuit, and some very rewarding results.
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.
Get X-ray intensifying/fluorescent screens from X-ray cassettes used for radiography.
