For those looking in for the first time, I’ll simply start at the end to show you my current 3D model collection (minus models I’ve given away) now that I’ve cracked using this excellent Crealty printer – and then we’ll head back to where it all started after the printer…
RunCam 5 Orange Ultra-light 4K HD FPV Camera
The full title of this tiny 4K camera is RunCam 5 Orange 12MP 4:3 145°FOV 56g Ultra-light 4K HD FPV Camera and despite having 4K capability on my mobile phone, decided I just had to take a look at this model. Of course the gold standard for these sports movie cameras…

Boxym Home Automatic Wrist Blood Pressure Monitor
The Boxym blood pressure monitor (model CK-W133) is simple enough and fits on the wrist – as against the more usual type that fit around the upper arm and that means rolling up or removing your shirt. As someone who checks their blood pressure regularly I’ve wanted one of these…
Sonoff DIY 4CHR3 and 4CH PROR3
This week I received a set of Sonoff units from Itead including the 4CHR3 and 4CHPROR3 (described as 4-gang Interlock/Self-locking/Inching WiFi DIY Light Switches) as well as a ZBMINI.

General Itead Sonoff ramblings – now with Zigbee
Sonoff Zigbee Bridge Early in June 2020 I received my long-awaited Sonoff Zigbee bridge along with Itead‘s pre-programmed Zigbee CC2531 USB dongle which means I have written about low-power-consumption Zigbee devices including Itead devices (also some from ZemiSmart). In this update I’m including the new Sonoff sensors, the ZBMINI which…
INUX3D TerraPi Dual SSD Assembly

UUGear RasPiKey eMMC module for RPi4
Arrived this week and now checked out – The UUGear RasPiKey. While a far cry from an SSD speed-wise, the RasPiKey seems like a nice alternative to an SD when running a Raspberry Pi 4 or similar because RasPiKey uses eMMC, which, while more expensive than SD, gererally has an…

LAOTIE N7S 3-Mode Foldable Electric Scooter
I’ll grant you the LAOTIE N7S 300W 36V 10.4Ah 3 Mode Foldable Electric Scooter is a little out of the ordinary for this blog – but when Banggood asked what I thought about the idea, I simply could not help myself as I’ve never owned an electric bike/scooter of ANY…

I have a couple of cars, one of which has a battery in doubtful state afet being flattened a few weeks ago. It works perfectly but knowing car batteries and their ability to recover from being flattened (or not) I at first figured I’d buy a battery charger – and…
