I realised it’s been a while since I played with anything new technically, and since observability is currently one of the hot topics in the IT industry it seemed only fitting to investigate sending and displaying metrics. Time is short & precious, so rather than setting something dedicated up, I Continue Reading
Raspberry Pi
Slowergram: Zero 2 W
Do you notice anything different when browsing this blog, maybe the boost in performance? Well that’s down to the underlying hardware hosting Slowergram being upgraded to a Raspberry Pi Zero 2 W, from the original Zero. Unfortunately, the upgrade wasn’t as smooth as planned. I had assumed I could simply Continue Reading
RPi4 booting from NVMe (over USB)
It just so happened that recently the USB booting feature for the RPi4 coming out of Beta and Amazon Prime day coincided around the same time. I took this as a sign to beef up my main RPi daily machine with some external storage which would be faster and also Continue Reading
Migrating from IFTTT to Home Assistant
So the time has come, IFTTT, the IF This Then (do) That cloud based automation service, has decided to try and further monetise by charging customers for a pro account if they want more than a basic offering, or more than 3 automations, known as applets. I used IFTTT for Continue Reading
Kubernetes cluster on a RPi (Part 3)
In the last part I deployed a very simple static web application, using the verification steps from the tutorial I was using. I combined this with some persistent NFS storage to preserve the data being served. I showed that this could be accessed from the cluster via curl from the Continue Reading
RPi – Cluster Case
As my collection of RPi4 k8s nodes has increased, I needed to bring a bit of order and tidiness to the setup. The best way to do this, I thought would be to house them in a stackable case. After a bit of searching I found this set from the Pi Continue Reading
Kubernetes cluster on a RPi (Part 2)
In the previous part of this post I stood up a basic 2 node k8s cluster using this excellent tutorial. I now need to learn how to use k8s and decide what I want and can use it for. The last part of the tutorial is around validation of the cluster, Continue Reading
RPi – POE HAT
I finally received my delivery of POE HATs for my RPi4’s today from CPC, and surprised at how easy they were to fit and get working. This is the first time I have used POE, and made sense to power my Pi bramble this way due to limited sockets where the Continue Reading
Kubernetes cluster on a RPi (part 1)
This post, and subsequent ones in the series are going to be a bit of a learning journey, as I am using it to document my learning around kubernetes. Obviously k8s (as the cool kids call it) has been around for a while, 6 year anniversary today, 11th June 2020, Continue Reading
RPI Spotify Connect Receiver (Part 3)
This is the last part in the series, see part 1 and part 2 Now I have all the pieces of the puzzle, it’s time to put them all together. The first job is to solder the GPIO header onto the Raspberry Pi zero W. A relatively straightforward task although I’ve not soldered Continue Reading
