103RS GPS Tracker Teardown

Posted on September 12, 2017 The Engineer

I thought it was time to add a bit of security to the gear I take camping, so this GPS tracker unit was sourced from eBay. This is a Rewire Security 103RS, a slightly customised version of the common Chinese TK103 GPS tracker. The small module has all it’s power

8-Port BNC Video Distribution Amplifier

Posted on August 3, 2017 The Engineer

Time for another eBay special: this time it’s an 8-port video distribution amplifier, with BNC connections designed for commercial/industrial equipment. Not much on the front panel above, apart from the power switch & LED. The rear panel has all the connectors, input is on the left, while the outputs are

Philips LED PAR38 Lamp Teardown

Posted on March 22, 2017April 24, 2017 The Engineer

These large LED Philips PAR38 lamps were recently on clearance sale in my local T.N. Robinsons electrical contractors for about £3, so I decided to grab one in the hopes I might be able to hack it into a low-voltage LED lamp. These are full-size PAR38 format, with most of

nb Tanya Louise Heating System – Oxide Sludge

Posted on February 1, 2017January 24, 2017 The Engineer

I wrote a few weeks ago about replacing the hot water circulating pump on the boat with a new one, and mentioned that we’d been through several pumps over the years. After every replacement, autopsy of the pump has revealed the failure mode: the first pump failed due to old

Tool Review – eBay Terminal Crimps

Posted on August 14, 2016August 4, 2016 The Engineer

I recently decided to restock my toolkit, as there are plenty of jobs I need to sort that require the use of crimp terminals, so eBay again came to the rescue. In my experience, cheap tools of any flavour are usually universally shite – I’ve had drill bits made out

Maplin 600W “Modified Sine” Power Inverter

Posted on January 17, 2016 The Engineer

I’m no fan of power inverters. In my experience they’re horrifically inefficient, have power appetites that make engine starter motors look like electric toothbrushes & reduce the life expectancy of lead-acid batteries to no more than a few days. However I have decided to do a little analysis on a

USB1100 Digital Message Unit

Posted on September 2, 2015 The Engineer

This is basically an industrial, rugged MP3 player, in an extruded aluminium case. They are used in commercial settings for generating telephone hold music or continual playback of background music in shops. It’s quite a compact unit, in a nice aluminium case, designed for mounting into a comms setup. This
