Updated Feb 29, 2020: And why would anyone write about a power supply? Not the most interesting subject, but like many boring things such as backups, essential. I created a short video several weeks ago about the Owon P4603 – a single channel job of particular interest as it has…

AliExpress Sinilink WIFI USB Controller
Today’s project for the day is the ESP8285-based “Sinilink WIFI-USB Mobile Phone Remote Controller” (or Sonoff for USB” as others have called it) – which handles up to 5 amps and can use a USB connection of from 3.5 to 20v (I’ve only tested 5v). Later I will describe how…
Bakeey E70 Waterproof ECG, Blood Oxygen and BP Smartwatch
I’ve updated 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 because it has now been on my wrist for 7 solid days and the battery is still at 68%.…

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…
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…

A classy looking job with “leather” look strap, default classical-looking analog…

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…
