Anker PowerPort Speed 5 12v DC Conversion

Posted on July 14, 2017July 14, 2017 The Engineer

A few months ago I did a teardown on this Anker PowerPort Speed 5 USB charger, but I didn’t get round to detailing the conversion to 12v I had to do, so I’ll get to that now I’ve got a couple more to convert over. Here’s the internals of the

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

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

Magnets in High Power or Precision He-Ne Laser Heads

Effects of Magnetic Fields on He-Ne Laser Operation If you open the case on a higher power (and longer) He-Ne laser head or one that is designed with an emphasis on precision and stability, you may find a series of magnets or electromagnetic coils in various locations in close proximity

Eberspacher Tent Heating System

Posted on January 17, 2016March 12, 2017 The Engineer

I go camping on a regular basis here in the UK, and often even in summer it’s horribly cold at night in a field somewhere in the middle of Leicestershire. This doesn’t go too well with my severe aversion to being cold. For the past several years I’ve used a

ViewSonic VA2232W-LED Monitor 12v Conversion

Posted on December 15, 2015 The Engineer

On the quest to get things on board replaced that are heavy users of power, the monitor in the main cabin was next. The original CCFL-backlit monitor was very heavy on 12v power, at 5A. This meant falling asleep watching TV would result in severely flattened batteries. Replacement with a

Solderless N-Type Connector Fitting

Posted on July 22, 2015July 28, 2015 The Engineer

I thought I’d detail the process I use to fit an N-Type connector to a coax cable, as I don’t usually solder these connectors. Before stripping, fit the backnut, washer & rubber seal onto the cable. The cable is first stripped back to reveal the shield. This cable has a
