Posted on November 7, 2021 by lui_gough

Over time, I’ve participated in a number of surveys, beta tests and other incentivised research which has resulted in my slow accrual of Amazon (US) gift cards. While I’ve given some of these away to random internet friends who reside … Continue reading →

Review: Micsig DP10007 (700V,100MHz,10/100x) High Voltage Differential Probe

Posted on October 31, 2021 by lui_gough

My recent review of the Infineon 3-Phase FOC Motor Drive Evaluation Board (EVAL_DRIVE_3PH_PFD7) had me wishing that I had more high-voltage differential probes to allow for safe probing of high-voltage circuits. Luckily, an online shop felt the same by having a … Continue reading →

RoadTest Review: Infineon 3-Phase FOC Motor Drive Evaluation Board (EVAL_DRIVE_3PH_PFD7)

Posted on September 18, 2021 by lui_gough

Things have been a little quiet around here lately and part of the reason is this – the Infineon 3-phase sensorless motor control evaluation kit (EVAL_DRIVE_3PH_PFD7) board which I was selected to RoadTest. This particular board features Infineon’s IMC101T-038 iMOTION … Continue reading →

Posted on September 5, 2021 by lui_gough

Posted on September 1, 2021 by lui_gough

As a person that’s tested many power-banks, it should come as no surprise that I literally have so many of them that I will probably never use them all. I need another power-bank in my life as much as I … Continue reading →

Posted on August 21, 2021 by lui_gough

Quick Review, Teardown: 802.3at/bt Power-over-Ethernet (PoE) Power Injectors

Posted on July 11, 2021 by lui_gough

I’ve been quite busy recently, in part, because I’m doing a few RoadTest reviews. One of them in particular involves the use of Power-over-Ethernet (PoE), but as I don’t already have any “standards-complaint” PoE equipment, I needed a cost-effective means … Continue reading →

Tested: STMicroelectronics LDL1117S33R SOT-223 3.3V LDO Voltage Regulator

Posted on April 9, 2021 by lui_gough

Readers may have recently noted my less-than-satisfactory experience with a batch of AMS1117 SOT-223 3.3V linear regulators which had no thermal protection capability whatsoever, bridging the input to the output as it failed with potentially disastrous consequences. Alas, as such … Continue reading →

Posted on April 3, 2021 by lui_gough

When you need to regulate a higher DC voltage to a lower DC voltage, the thing that comes to mind first is a linear regulator. While they’re horribly inefficient for large voltage differences, they’re usually pretty bulletproof, produce relatively “quiet” … Continue reading →
