Mercury 30A Ham Radio SMPS

Posted on December 14, 2016 The Engineer

After having a couple of the cheap Chinese PSUs fail on me in a rather spectacular fashion, I decided to splash on a more expensive name-brand PSU, since constantly replacing PSUs at £15 a piece is going to get old pretty fast. This is the 30A model from Mercury, which

Thorn Ultra 6816 B&W CRT TV Teardown

Posted on December 1, 2016October 16, 2019 The Engineer

The other day at the local canal-side waterpoint, this TV was dumped for recycling, along with another later model Colour TV. This is a 1970’s Black & White mains/battery portable made by Thorn. It’s based on a common British Radio Corporation 1590 chassis. Having received a soaking from rain, I

Panasonic NV-M5 VHS Camcorder Teardown

Posted on September 8, 2016August 20, 2016 The Engineer

Overview Time foe some more retro tech! This is a 1980’s vintage CCD-based VHS camcorder from Panasonic, the NV-M5. There are a lot of parts to one of these (unlike modern cameras), so I’ll split this post into several sections to make things easier to read (and easier to keep

eBay Flyback High Voltage PSU

Posted on September 1, 2016August 16, 2016 The Engineer

I have found myself needing some more in the way of High Voltage supplies of late, with the acquisition of the new He-Ne laser tubes, so I went trawling eBay for something that would be suitable to run these tubes. (I currently only have a single He-Ne laser PSU brick,

Modular He-Ne Laser Power Supply

Description and Schematic SG-HM2 is a modular He-Ne laser power supply based on IC-HI1 with some minor enhancements. The first version is for laser tubes up to approximately 1 mW (2 mW with trivial modifications) but it should be straightforward to go to 5 mW or even higher power tubes
