Some time ago, I noted a company called Elecrow in connection with a kit to turn a Raspberry Pi into a laptop (it’s all on their website in the link above and check out their Indiegogo link). But the RPi is NOT what this blog entry is about. I’m not…

Huawei Honor Band 6 v Xiaomi Mi Band 6
When I wrote the first part of this back in April 15, 2021- it seemed that AliExpress would have the new Huawei Band 6 (GLOBAL) that week to I guessed that meant we outside of China would not be able to actually get one for maybe another 3 weeks –…
Eleksmaker A3 Pro 3500mW Laser Engraver
The A3 Pro is proving to be a MARVELOUS engraver. Some of you may recall back in 2018 I wrote about the original Eleksmaker Pro engraver – it came with a 400mW laser module which was rapidly replaced with a 2300mW laser and very nice too. I left that with…
Perfect Prime IR202 Thermal Camera
Having just recently written up the Perfect Prime IR281 thermal camera (not cheap) I thought it might be useful to take a look at the less expensive add-on for mobile phones version IR202 from the same company. I’m showing photos of all three variations of this mobile phone add-in camera,…
Broadlink Bestcon MCB1 Smart Home WiFi Switch
I just received one of these from Banggood – and I’m struggling to see what’s special about them, apart from the price that is. Depending where you live these could be as low as €7.38 + €1.68 shipping (price given here in Euros). Ok, it’s a neat, small box with…
Rechargeable Cordless Air Duster – Heaven for Engineers?
Banggood just sent me a and I LOVE it. After a lifetime in electronics, I can’t begin to tell you how many cans of compressed air I’ve bought over the years. Back in the UK, being a business, we would shop at Costco – and as well as cheap hotdogs…
The saga of Raspberry Pi 4 Power Control and Dual Sata (SSD)
Like other Raspberry Pi 4 owners I’ve been wrestling with which is the best power option – can I use 2 SSDs – how do I ensure which SSD will start first – what case to use and related questions – well, I’m at an interesting peak with this right…
Comparing Various Disk Device Speeds Updated)
As I have several disk devices sitting in-between jobs, I thought it might be nice to run a speed comparison between them using CrystalDiskMark, my new favourite PC tool for speed-testing disks. Before I start I should sake it clear that I did one test each in identical conditions (USB3-based…
Perfect Prime IR281 Thermal Imaging Camera
Interested subscribers may remember my write-up about the Perfect Prime IR005 camera back in June 2020. Infra-red resolution was 220×160 and visible resolution was 640×480. Well, the New IR281 Camera has similar resolution while having a somewhat (IMHO) better feel to it – but that doesn’t really cover the improvements…
GL S1300 Convexa-S Smart Home Gateway
At one time or another I’ve covered many of the GL-iNET range of routers with more to come (Remember the little MANGO travel router?). I’ve been using a home setup comprising a TP-LINK W9980 VDSL2 main router attached to the local Internet provider’s modem for some time, following a lightning…
Ranger 2C Indoor Smart Security Camera
You may recall some time ago I did a review of the Bullet 2C camera from Imou. Well, it has taken some time but I finally have my hands on the new Ranger 2C Smart Security Camera. They’ve given me some info – links etc (see below) but first, why…
ESCAM QF260 WiFi Solar Camera
Described on Banggood’s website as the “”, this looks remarkably like my original YN88-WIFI-130W described here. Well, THIS new WiFi camera also has the term “Watchmen” on the box but is a later model using a newer APP. The QF260 comes complete with two bright white LEDs and two infra-red…
