The Fujifilm PMT26A photomultiplier tube module came from a teardown. The teardown of a Philips / Fujifilm PCR Eleva S / CR-IR 357 X-ray image scanner for computed radiography, became the basis for this reverse engineering project. You can see the teardown of the entire Fujifilm PCR Eleva S machine here. Teardown of the polygon […]

Reverse engineering of laser scanner module from a Philips / Fujifilm PCR Eleva S 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 illumination with a photomultiplier tube setup. Part 1 pictures and long

This is a complete teardown of a Philips / Fujifilm PCR Eleva S x-ray image scanner system. Full of stepper motors, laser stuff and photomultiplier tube! If you are specifically interested in x-ray equipment and x-ray image scanners, you are in luck. I have done numerous teardowns and reverse-engineering videos on this kind of equipment.

Teardown of Cisco Cable TV EGC GAN node and drop amplifier. Electronic Gain Control (EGC) technology and GaN (Gallium Nitride) monolithic microwave integrated circuits (MMICs}. These are modern versions running on fiber networks. These small amplifiers are used in houses where it is not practical to use a receiving antenna to get the signal from

A look at a bag of IGBTs and MOSFETs that I quickly salvaged from industrial electronics. Found in induction cookers, solar inverters, welding machines, car and battery charges. It can also be other common high power electronics with switching inverters. Discussion of salvaging IGBTs/MOSFETs: https://highvoltageforum.net/index.php?topic=2117.0 These TO-247 IGBTs can be used in a DRSSTC Tesla
