uRADMonitor is a network connected monitoring station, focused on continuous Environmental Radiation Surveillance. This capability is delivered by a digital dosimeter constructed around the highly sensitive Geiger Muller tube SBM20U. This is a uRADMonitor that I have installed outside of my appartment in Odense, Denmark. The system is currently under development by Radu Motisan from […]

The latest update to the 100 Watt 6P45S tube amplifier is the measurements of frequency response from square waves and bandwidth measurements. The prototype is now considered done as it has proved itself capable of outputting 210 Watt peak before clipping. At 100 Watt peak it have its -3dB points at 11 Hz and 72

Due to a busy work year and not many days at home the progress with the large DRSSTC have been very limited. I have however updated the article with the testing progress and fault finding that have been done. New video and pictures can be seen here: https://kaizerpowerelectronics.dk/tesla-coils/kaizer-drsstc-iii/ Learn how to build your own Tesla

I have completed building and initial testing of a new tube amplifier prototype. It uses the Russian 6P45S tubes in the output stage. This prototype will be used for testing, tweaking and a way to perfect the amplifier before building the final version. Read more about the amplifier, the progress and see the pictures at

It took some years and someone recently bumping up my old thread about this project for me to write up a article. I had to dig around a bit to find the pictures, make a video and get it on here. Read all about the design and construction of the TL494 flyback driver here: https://kaizerpowerelectronics.dk/high-voltage/tl494-flyback-driver/

First test run of the Royer induction heater. It is running with a maximum of 650 Watt power consumption. As a result thereof, there is heavy voltage sag on the DC supply. The work load being heated is a M10x20mm bolt. Further videos will be released, when improvements have been implemented. Read the full article
