I currently have The Eclipse Mosquitto MQTT broker running on the Raspberry Pi 2, 3 and 4, Buster Raspbian, not to mention countless other variations of Debian and Ubuntu on various boards used at one time or another in the past (Orange Pi, various FriendlyArm boards and many others). Below…

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…
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…
Enter Monitorix
I recently did a post asking for input about useful tools for the Raspberry Pi and other SBC boards and the first to some out of this is Monitorix. This is just a short blog – I’ve not had enough time to ensure I understand the usefulness of this –…
The Script and RPI 3 Update
Having started putting together “the script” a long time ago, long before the Raspberry Pi 3 came out – and having developed it to handle a wide range of boards and scenarios including of course the Pi3, I found it interesting to return today to installing “the script” on the…
Grafana and InfluxDB
Some time ago I wrote a blog entry about garden sensors inside of which was buried some information about using Grafana and InfluxDB. At the time the install was not that easy – and when along came STRETCH for the Raspberry Pi (2 and 3) it got worse. However, reader…
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…
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…
I2C Expansion for Pi and ESP8266
Want 64 GPIO pins on your ESP8266 or Raspberry Pi? Read on. If like me you are not THAT familiar with I2c, you might find the results of my experiments interesting and perhaps even useful. If like me you are not THAT familiar with I2c, you might find the results…
Sparkly new Pi
Just a very quick one (and somewhere to park the conversation)– there’s a new Raspberry Pi update out promising a new smoother, simpler look, better video etc. Up to now it looks like the claim is correct. I have several RPI installations…including TightVNC and so I didn’t want to lose…
NOT Rip-Off Britain for Raspberry Pi
Here’s a bit of a reversal.. normally I steer clear of the UK for pricing as we tend to pay over the top… I can’t help thinking I’m reading this incorrectly…. However – here above is RS Components latest pricing for the Raspberry Pi 3 – the latest model –…
Cheap Pi Screen
I have a Raspberry Pi 3 and recently bought a 5” screen from here at sub-£20: While the instructions on Ebay totally miss talking about the touch screen which does not work by default, this blog entry – https://blog.ask-a.ninja/?p=48 is absolutely bang on – the screen instructions are more precise…
Useless Pi Browser and Firefox
Why oh WHY do they keep that utterly USELESS Web browser in Raspbian? I powered up my new Raspberry Pi today on my new 5” LCD display and tried loading up Node-Red on the browser. That went well until I tried to edit a function – blank white window.…
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 Grand Opening
After a couple of tense hours, the doorbell rang this morning – the RS delivery guy with my brand-spanking new Raspberry Pi 3. So was it worth getting? Is this going to kill the competition? Should I have stopped in bed? The Pi arrived in the usual oversize box –…
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…
Raspberry Pi 3
So firstly, in case you’ve been on a desert island, what is a Raspberry Pi 3 and why do you need one right now? The Raspberry Pi is a general purpose tiny computer with USB, Ethernet, audio, HDMI etc and this works using an SD card to store the operating…
