In this video I build an electronic clock kit! I attempt to do it with a cheap USB soldering iron, but don’t last long before switching back to the Hakko. I also offer a few soldering tips and useful tools and gear. It’s a decent little clock with animated LEDs, time, date, temperature, and light […]
I was unable to find the user manual for the PROVA 23 Power Harmonics and Leakage Tester anywhere online, so I’ve scanned it in and made it available as a PDF here:
In this video I review and teardown a compact and very bright video and photography light. I have an upcoming video that shows colour temperature and brightness measurements and my overhead lighting configuration. *This is an unpaid, non-sponsored review* Further information eBay product page Workbench shelving video I reference (YouTube)
In this video I review an automatic car battery charger and measure how affective it’s 7 stage charge cycle is but monitoring it’s voltage and current. *This is an unpaid, non-sponsored review* Here’s another video where I do a quick teardown of the charger to see how it’s built and the quality of its components. […]
In this video we look at the Facit NTK Mechanical Calculator from 1957! In this video we answer some questions from the last Facit NTK Mechanical Calculator video. I explain how the decimal place markers work and what happens when you divide by zero! Further information John Wolff’s excellent website User manual (PDF) I refer […]
In this video we look at a dirt cheap wireless energy meter that is surprisingly accurate. We put it through its paces before tearing it down to see how it works. Further information Altronics product page Atmel AT24C02 datasheet (PDF) Cirrus Logic CS5460 datasheet (PDF)
In this video I review and teardown the Turnigy Infrared Thermometer, which is a rebadged ZyTemp TN105i2 Compact IR Thermometer. This is a great piece of kit for any electronics workshop! Further information ZyTemp (manufacturer) page Instruction manual (PDF) HobbyKing (distributor) page

In this video we learn about the Hall effect. This is a quick history and explanation to help you understand some brief theory and how it works.
In this video we take another look at the RS-232 plug-in module for the Sanden PET-07 CC/CV power supply. In particular, we see how the voltage output can be controlled and how this clears up some ambiguity with the circuit design. In part three, we will *finally* attempt to communicate using RS-232 to monitor and […]
