Some time ago I wrote about the Sonoff inexpensive Zigbee dongle and various Zigbee hubs etc. At the time I was experimenting with HA (Home Assistant) and a load of other new things and didn’t really give Zigbee the attention it deserved. I’ve now come back to this with a…
Owon HDS272S Handheld Oscilloscope
Over the years I’ve had a number of Owon scopes, function generators and power supplies – so I’m pleased to now have my hands on their handheld HDS272S, a new, portable dual-channel scope which can also be used as a multimeter and function generator. As you’ll see, the scope/meter has…
Xiaovv B1 3MP Waterproof Outdoor IP Camera
Ok, so another outdoor video camera – so what? Well, unlike some other low-priced IP cameras – this one is 3MP as against 2MP – that’s a good start – and I noted it uses the V380 APP – which I already use with other WiFi IP cameras. AI human…
Atomic Radio-Controlled Silent Clock
This will be a short one about this clock module I just received from Banggood – not much you can say about a radio clock module that isn’t in the spec above. I’ve been using clock modules like this for years, this one works off the “Rugby” Transmitter in the…

Alexa-Applestrudel (formerly Cakebaked formerly Remote2)
That’s node-red-contrib-alexa-applestrudel etc. – but the title was getting too long:-). This article is about Alexa-related “nodes” for Node-Red. To give this set of eight nodes (seven visible) their full title, the original offering was known as node-red-contrib-alexa-remote2 and when I first wrote this blog entry in September 2019. The…
Xiaomi Mijia 1S Second Generation Smart Vacuum
For a few days now we’ve been testing the very neat 2nd generation Xiaomi Mijia 1S Robot Vacuum Cleaner – I’ve provided a Banggood link here but I should say immediately that I’ve recently been told that Banggood cannot sell Xiaomi in the USA – so any USA-based subscribers might…

Elecrow Crowbits Kits – Beginning Electronics
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…

Interested viewers will find that as well as the normal msg.payload…
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 MCB1 units 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…
Athom pre-Tasmota’d Smart Socket and Smart Lights
I’m so excited about this so I’ll dive straight in. The company is called ATHOM and they make smart sockets and lights pro-programmed with TASMOTA. I took the smartsocket out of the box, plugged it into the mains, told my phone to look for access points and it found “tasmota_D3F950-6480”.…
Rechargeable Cordless Air Duster – Heaven for Engineers?
Banggod just sent me a rechargeable Cordless Air Duster 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…
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-iNET GLS1300 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…
