The Argon ONE case is very pretty (but then it is not cheap so you’d expect that). It has variable control over the built-in fan and I had to ramp up the settings as the fan was initially off even though the case was very warm – now the whole…

Raspberry Pi 4 Arrival
My 2GB Pi4 arrived from the UK. My good friend sent me a micro-HDMI to HDMI adaptor along with the Pi and a 3d-printed case he made – except he didn’t…. the adaptor is a micro-USB to HDMI adaptor – NOT what the RPI4 uses. Because I’m impatient I’d already…
Raspberry Pi Serial Port
Over the past couple of years, I’ve installed operating systems on a number of little boards and I have to say, that while the Raspberry Pi with Raspbian is generally the easiest when it comes to enabling GPIO, the serial port can be a pain. Here is how to ease…
A Short Piece About Webmin
When referring to “the script” which installs Node-Red, Mosquitto, SQLite and a host of utilities onto Raspberry Pi and other boards and forms the basis of all of my installs, I rarely mention Webmin, as it is just part of the furniture… however this morning I noted that my test…
RPI Prototyping
Remember a few blogs back where we were talking about prototyping boards for Raspberry Pi and similar and I showed a sample board and someone came back and said “Ah but you can get cheaper on AliExpress” – well, I bought one… Here’s the link – £1.09 in sterling, free…
Your Favourite Pi Things
On the blog here we refer often to “the script” which sets up a whole raft of useful tools on SBCs such as the Raspberry Pi – and we’re always on the look out for new and improved tools. But let’s here from YOU! So we already know from extensive…
Raspbian Stretch and GPIO Utility Fix
If any of you have installed the new “Stretch” version of Raspbian on the Raspberry Pi, you may have noticed a slight issue with the wiringPi GPIO utility.
The Real Raspberry Pi
I’ve been using the likes of FriendlyArm boards and similar for so long now, struggling at first with GPIO and I2c and as regular readers will know, finally pretty much mastering it due to hard research and more importantly, the works of people you’ll find links to in other articles…
Thoughts on RAM
These are just thoughts – hopefully someone is going to write in and tell me I have it all wrong. As regular readers will know I have reviewed (and messed with) MANY small Pi-type boards including the Raspberry Pi, Banana Pi, NanoPi etc etc. I’ve also had a go with…
Raspberry Pi 3 Serial
Just bought a new Raspberry Pi 3 with WIFI and Bluetooth? Using it in a project with serial? Happy? Well, you might not be so happy when you find out what I just found out. I had my Node-Red project that has been controlling the house for around 18 months…
Alexa Enlightenment
Last updated November 16, 2016: In a recent blog entry I told you how we’d been playing with Amazon Echo (Alexa) and got it working. Well, nearly. It turns out that what SEEMS obvious in the system is not all it seems – but read on as we’ve had success.…
A Brighter Node Red
Just today – an upgrade notice for Node-Red appeared in my in-box. Upgrade details are here. What is Node-Red? Details here – if you’re not using it or at least investigating it – you may be missing out. Now, the support guys (Google groups here) are VERY clear about required…
Background Beavering
You could be forgiven for thinking I’ve gone off the boil as I’ve not written much in here this week… far from it in fact. This week I’ve been working on my ImperiHome setup and the new Raspberry Pi software. ImperiHome: In case you don’t know, ImperiHome is an app…
Visual Interfaces for IOT
So much happening right now – the new Raspberry Pi 3 once again sets the bar with improved performance, Bluetooth and WIFI as standard. With up to 10x the speed of the original Pi we can do even more serious work with these devices. Please note before proceeding – apparently…
Raspberry Pi 3 Spoiler
While waiting for my new Raspberry Pi 3 board to arrive so I can blog about it – I thought I’d jot down some thoughts following a conversation with a pal of mine in Canada. Today, a new Raspbian release came out supporting the 64-bit Raspberry Pi 3. Hopefully it…
Cheap Raspberry Pi
Now before you say anything – they don’t even know I’m writing this!! Remember when I was in Chicago a while back (well, you’ll only remember if you’re a regular reader)… I bought a Pi Zero and a Raspberry Pi dirt cheap at somewhere called MicroCenter in Chicago. Well they’re…
Pi Zero Wi-Fi Automatic Reconnect
Sometimes I wonder about the thinking processes involved in Debian setup. Why for example would you NOT want the Wi-Fi to reconnect on failure? What is the point? Yet, that does seem to be the default scenario, particularly odd when it comes to the Pi Zero – which has no…
Pi Zero and the USB Problem
The £5 Raspberry Pi Zero has great potential as a cheap gadget but it has one major problem – lack of USB. So it has no ETHERNET – your ONLY option is WIFI – but will the WIFI work and how the HELL are you supposed to figure that out…
Raspberry Pi Volume in Node Red
Over the course of my many experiments with the Raspberry Pi and similar I have had constant problems with volume – I remember wasting ages with the Orange Pi – no WAY could I get sound to come out of the analog output. Things are a bit better with the…
Raspberry Pi Zero
If you have been hiding recently you may not be aware of the new Raspberry Pi Zero. Hot on the heels of the CHIP and other low cost micros and by the look of it a zillion miles ahead of that daft BBC “Micro Bit” (there’s a shocker) the Raspberry…
