De La Rue Coin Counting Machine Followup – PSU Oddness

Posted on February 8, 2016 The Engineer

I did a little more digging into the PSU circuitry of the small coin counting machine, and it’s even more strange than I thought! The part I originally thought was a transformer on the PSU board is in fact a DC-DC converter module! Here’s the device after desoldering it from

De La Rue Coin Counting Machine

Posted on February 3, 2016February 3, 2016 The Engineer

Here’s some teardown photos of an old De La Rue coin counter, used in businesses for rapid counting of change into large bags. An overview of the whole mechanical system of the counter. Coins are loaded into the drum at the rear of the machine, which sorts them into a

Dell E207WFPc Monitor 12v Conversion

Posted on September 21, 2015 The Engineer

I’m still on my crusade of removing every trace of 240v mains power from my shack, so next up are my computer monitors. I have 4 Dell monitors, of various models, hooked up to my main PC. The monitor here is a Dell E207WFPc 20″ widescreen model. There will be

13.8v SMPS PSU Build

Posted on July 25, 2015July 29, 2015 The Engineer

A while ago I blogged about modifying the output voltage of some surplus Cisco switch power supplies to operate at 13.8v. Since I was able to score a nice Hammond 1598DSGYPBK ABS project box on eBay, I’ve built one of the supplies into a nice bench unit. Above is the

Amano PIX 3000x Timeclock

Posted on February 16, 2013 The Engineer

This is a late 90’s business timeclock, used for maintaining records of staff working times, by printing the time when used on a sheet of card. Here is the top cover removed, which is normally locked in place to stop tampering. The unit is programmed with the 3 buttons &
