I’ve updasted this blog entry about the Bakeey E70 IP68 Waterproof Wristband ECG+PPG Heart Rate Blood Oxygen Monitor Smart Watch (which looks lovely) as I think it deserves a second glance as it has now been on my wrist for 7 solid days and the battery is still at 68%.…

Raspberry Pi 4 and SSD – Miracles at Last?
I’ve just been watching a video by Andreas Speiss – and I agree with him, USB boot on the Raspberry Pi has taken FAR too long and we are NOT a tiny minority in favour of USB boot, contrary to comments in the Pi forums. The PI3 had USB2 boot…
Instar IN-9008 Full HD MQTT Wired/WIFI IP Camera
I just received a nice IP camera from INSTAR Deutschland (Germany) GmbH – the IN-9008 Full HD camera (1920×1080). I’ve had several emails from Mike Polinowski of Instar – and this is the end result – the “first ever” MQTT IP Camera. I have to say it LOOKS good –…
Xiaomi ZAJIA Auto-sense IR Induction Water Saver
I LOVE getting new toys – and this time I think Maureen likes this one too. Clips straight into the tap in the kitchen or bathroom to provide proximity-controlled water supply. If you are on a meter or just environmentally-conscious – this battery powered (USB rechargeable) device might just be…
Blitzwolf BW-HL2 Smart Watch
If like me, you are aware of Blitwolf (actually the name often takes me back to “Wolfensten”) you will probably think of battery packs or even WIFI-controlled power sockets or adaptors…. but here we have a Blitzwolf BW-HL2 WATCH. A classy looking job with “leather” look strap, default classical-looking analog…
NanoPi R2S OpenWrt miniRouter – great for testing
The new FriendlyElec R2S is more fully described as NanoPi R2S: a Raspberry Pi alternative that incorporates two Gigabit Ethernet ports. That’s not strictly true, it is nothing like an alternative to the Raspberry Pi 4, for example, but with 1GB RAM it runs OpenWrt – the FA version which…
Deerma VC20 Ultra Light Cordless Vacuum Cleaner
Ok, I know this isn’t strictly high tech – but I promised Maureen I’d get her a new vacuum from China and here it is – the Deerma VC20 Ultra Light Cordless Vacuum Cleaner This neat cordless vacuum just arrived, having been (almost) delivered at the start of January JUST…
Smoke Alarms, Door and Water Leakage Sensors for RF-Bridge
I recently wrote about the Sonoff RF-Bridge – a great device for transferring RF signals from various gadgets to WIFI – well, first things first, I put Tasmota on the RF-Bridge so now, using the free Tasmota Device Manager on it, I can receive information from devices and that gets…
Xiaomi Redme Note 8 Pro Smartphone
I’ve been waiting for the Redme Note 8 Pro Smartphone (Xiaomi – Global version) for quite a while now, ever since Banggood sent off a Bakeey cover for the Redmi Note 8 Pro phone when all I had at the time was the original Note 8 (there IS a difference…
New for 2020 – Bluetooth 5.0 Earbuds and much more
Having spent much of January visiting family in Chicago, USA – I’ll be back to working on the blog in the next day or so. Much to catch up with as well. You would not believe the things that have gone wrong remotely while I was away in freezing cold…
High Power Mains Switching with Sonoff
I am as most of you know a great fan of the Sonoff BASIC modules – because, in the main, they are cheap and reliable – but increasingly I’ve been faced with challenges that involve the need for isolated contacts – or high power (immersion heating) or both. Well, here…
Owon ODP3033 Bench Triple Power Supply
And why would anyone write abut a power supply? Not the most interesting subject, but like many boring things such as backups, essential. I created a short video last month about the Owon P4603 – a single channel job of particular interest as it has a “proper” toroid instead of…
