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 I review and teardown a cheap Motion Activated PIR Solar LED Light from Amazon. The product is described as a: Swiftly Done Bright Solar Power Outdoor LED Light Further information Amazon product page
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 […]
In this video we take a look at the Sanden PET-07 CC/CV power supply. In particular we look at the RS-232 plug-in module and attempt to make sense of the signals between the main board and plug-in board. In part two, we’ll apply this knowledge to attempt to receive RS-232 data from the power supply. […]
Here’s some photos of the Protek 608 RS-232 cable teardown: Bill of materials You know a teardown is serious when a BOM is produced! 😛 This may be overkill, but I have plans in future to develop my own transceiver hardware that instead of using RS-232 to connect to a PC, it will use a […]
I’m sick of seeing this notification! I’ll usually only get 20 minutes play time before the controller requires charging again. I’ve had it on charge for weeks, since the last time I used the PS3. I don’t use the PS3 often, and I’m holding out for Uncharted 4 next year before I consider buying a […]
