Schematics, instructions and pictures on how to build high voltage power supplies or projects like flyback transformer drivers.
Teardown of a standalone x-ray head from Showa (Made in Japan). Capable of outputting 100 kV at 35 mA for up to 10 second exposure times. It comes as a complete unit with collimator, only to be supplied with 230 VAC and operated with external trigger. If you like to see more teardown articles, pictures …
Reverse engineering of the Fujifilm PMT12A PMT module that contains the photomultiplier tube, high voltage power supply and analog amplifier from a Fujifilm FCR XG-1 x-ray image scanner / digitizer. Also known as Computerized Radiography (CR), it fulfills the job of scanning a x-ray exposed image plate with a laser beam and extract each pixel …

Teardown of the photomultiplier tube assembly (PMT) and its high voltage power supply. The high voltage power supply and PMT is reverse-engineered. The PMT will be used as a cosmic ray detector with a scintillation plastic crystal in front of the PMT. Part 1 is the Teardown of a AGFA ADC 5155 x-ray image scanner …

In a celebration of reaching 10,000 subscribers on Youtube, I blew up some pieces of wire with my 2500uF / 2kV Maxwell energy discharge capacitor storing 4kJ of energy. I also started a new dedicated slow motion video channel, please subscribe if you like to see more non-electronics videos recorded at high speeds: https://www.youtube.com/channel/UCB2qu77PCr5i9zcs0sOhp4w/
This video shows the different fuses, breakers, MCB, RCD, melting fuses and automatic fuses that I have. I started spring cleaning my work shop and I have come across so many components in various bins, boxes and drawers that I finally had some time to get it sorted and put together in groups. High Voltage …

I give an overview of a 65kW X-ray generator system for a 70 kV X-ray transformer. The full-bridge of 400A 1200V IGBT bricks makes for a powerful inverter to drive the ferrite cored high voltage transformer.
I go through my collection of iron/ferrite core high voltage transformers. MOTs, OBITs, NSTs, PTs and X-ray transformers. Microwave Oven-, Oil burner ignition-, neon sign- potential- and x-ray transformers. I forgot to add the old and new flyback transformers I have… somewhere…
