Having been guilty of being ignorant of the developments in low-Rds(on) MOSFETs as of late, I used to think that 30mOhm was a pretty decent Rds. But then I decided to stray outside of the parts I used to use...

Recently, I had some bad luck with my Sandisk Ultra Flair 128GB USB 3.0 Flash Drive which failed after a few years of read-mostly operation. While initial recovery seemingly went well, the RMA process was protracted as the replacement item...

A few weeks ago, a generous reader asked whether I’d be interested in reviewing a USB-C PD charger rated at 100W that could be obtained at the suspiciously low price of AU$28 on a promotional sale. The price alone piqued...

It’s been too long since my last random posting … my brain’s been slowly filling up with random snippets that aren’t exactly enough to become their own full-blown post. That is, despite, being boxed-in at home to avoid the worst...

A couple of weeks ago, I posted my scpibenchv1 post about benchmarking SCPI commands on compatible test and measurement equipment. In that post, I did mention that the use of different VISA layers would likely affect the results in some...

If you’ve been wondering why it’s been a bit quiet recently around the blog, well there’s a perfectly good reason for that. I’ve been very busy pulling together everything for the Aim-TTi QPX750SP RoadTest Review. It’s no big secret that...

I have been fortunate enough to have been selected as a reviewer for numerous types of test equipment over the years and have been a big advocate for the use of SCPI automation, I have seen differences between different products...

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...

Apologies for the inconsistent blogging schedule – I’ve been totally swamped with work (as usual), but some things take more time than expected as I keep thinking of new things to try. This post is a follow-up to my previous...

It’s been a while since I’ve done a project of my own, but I had a bolt of inspiration all of a sudden thanks to my recent repair of a sub-standard modified sine-wave inverter from China (and a brief mention...

This is another post that probably belongs to the “long overdue” pile. Back in 2019, I decided to buy a USB-C PD capable charger to allow me to charge my work laptop while at home. At the time, the safest...

On my recent review of the Blitzwolf BW-P12 10000mAh Power Bank, a reader commented asking whether that particular power bank could be used as a makeshift uninterruptible power supply (UPS) for USB-powered devices. This is an excellent question and one...

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...

This post was meant to be a short post to be published right after the delivery of my Microchip PoE to USB-C Adapter RoadTest Review, but somehow, I must have dreamed of publishing it because when I came to look...

It’s time to run a few experiments. You get to your lab and turn on your power supplies and electronic loads and they start-up, ready for action. For safety, most of them start up with their outputs off. Seems simple...

It’s been absolutely ages since my last random posting which happened at the end of June when Sydney was just entering its COVID-19 delta-strain-induced lockdown. Since then, lockdown has been continuously tightening its grip with very little result to show...

This final post looks at a few of Tokyo’s other districts which I spent very short periods passing through and is a collection of otherwise small random observations made while moving between attractions in the Tokyo area that didn’t deserve...

I would usually not have much need for an inverter, as I do have a pair of HIP-300 units which are still serving me well, but recently that changed as I was entrusted to review a fairly beefy power supply...

No trip to Tokyo is complete without a trip to its many districts, many of which have their own special theme of sorts. This posting details my visits to Akihabara, Odaiba, Ikebukuro, Ginza and Tsukiji. Akihabara Any electronics nerd or...

Things have been a bit quiet lately on the blog, as the protracted lockdown takes its (mental) toll in terms of keeping me busy with umpteen things to do at home both on weekdays and weekends. The physical need to...

While recently getting a PCB made for a specific review requirement, I had the opportunity to build a few more designs and bundle it in for some cost savings in the form of combined shipping. I figured since I was...

It’s been a little quiet around the blog lately. Part of this has been down to working from home and the draining prospect of the indefinite lockdown we are facing in Sydney at this time. Another part has been the...

If you’ve been following along the blog, you might have wondered why I recently took a look at some Power-over-Ethernet injectors, specifically one that supported 802.3bt Mode 4 “90W” power. At last, it is time to unveil my latest RoadTest...

I’d have to say, all hope of our COVID-19 lockdown easing are completely dashed as numbers continue to hold stable or rise subtly, and the outbreak is officially declared a “national emergency”. The premier’s “best health advice” led us down...

Apologies – I’ve been so busy and mentally exhausted that I started this post last week, but didn’t finish it off until now … Rather disappointingly, but to no great surprise to me, our COVID-19 Delta-strain-induced lockdown has persisted and...
