Another day, another random display from WaveShare that has pretty poor documentation, and me trying to get it working with CircuitPython... I must be CRAZY NB: As always, I waffle on a bit here... click here to skip to the tl;dr technical details I do feel like I am losing the plot with these sometimes... Continue Reading →
If you are going to build a Pi Cluster using K3S, the easiest way to get up and running is to use the pre-baked setup script from k3s.io However, as with all things linux/pi... there's a few steps you might want to do first. Initially flash your pis all with the Raspberry Pi Imager using... Continue Reading →
I recently purchased (read: impulse bought) two of these Waveshare 1.47" SPI Displays, with curved corners. Looks pretty great, and I thought it might be interesting to use in a project that I am working on using a Raspberry Pi Pico W, they have a picture of it wired up to a pico on the...

Look, this is nothing new, I haven't invented anything clever, but I couldn't find an easy copy and paste solution to take a string (of any length), encrypt it with a password... and then decrypt it later on with Circuit Python. I should start by saying, I'm not a python expert, I'm barely even a... Continue Reading →
As always, this is a rambling rant about how/why I came across this solution. If you want to skip to the copy/paste, click here. I used to love webjobs... they were great. I also used to love Azure Service Bus... it offered so many features, and Service Bus Explorer is fantastic for managing the queues... Continue Reading →
This should be simple right? Even with the new yaml pipeline editor, you should be able to do the old 'build and push' and fire a few arguments in. Nope. Doesn't work. Here's how you can do it..
If, like me, you have recently discovered the power of the .devcontainer functionality of VS Code and it's remote debugging, you will maybe be dismayed that there isn't support for net5.0/.Net 5 yet. However, as we are developing a new API at the minute, that's not yet released, we upgraded it to net5 to see... Continue Reading →
We use a redis server for caching some basic requests in our web apps. Recently we were seeing redis timeouts during testing... there was no server load, there were about 7 requests being processed a minute, and our redis server was reporting roughly 1% capacity for usage.... strange. We were using the package Microsoft.Extensions.Caching.Redis Version... Continue Reading →
I am no expert on these things, but essentially the Pi 2 and the Zero run an older processor, ARM6 types to be precise. The issue when you try to install docker using their excellent one liner, it barfs right at the end with a failure....
Easiest way to keep yourself from losing your keys? Don't carry them. Security is more important than ever these days, especially with all the public data breaches in the news. As developers we are trusted with the keys to the kingdoms for all the systems that we work on. We are also human. We make... Continue Reading →
