Seriously, who remembers HTML image maps in 2023? These days, web developers who were not around when the internet and HTML were still in their infancy in the 90s don’t know this cool feature that is HTML image maps.

Let me help you install IOTstack on a Mac Mini. Why? Just because you can? Well, maybe. The true motivation, however, is that I had an un(der)used late 2012 Mac Mini at home that looked to be perfectly suited to run a few Docker containers. The IOTstack README introduces the project like this: IOTstack is […]
Recently I found my self looking for suitable spare batteries for a Carrera Mario-copter drone. The Mario-copter is a fun entry-level drone for kids (8y+). It is reasonably priced and easy to handle.

Look around the internet for “PyInstaller virus” and you will get lots of hits such as here, here, and here. In order […]

A reader notified ThingPulse – of which I’m a co-founder – because the project’s Arduino sketch relies on an open-source display driver provided by ThingPulse. I was immediately intrigued as the project involves electronics, software and classical woodworking. As a […]
I’m still giddy; giddy about Docker buildx; giddy about creating multi-arch Docker images on my Mac and having them uploaded and properly stored on Docker Hub with a single, simple command. Why I needed Docker buildx Docker makes my life so much easier – period. Unless there is really good reason to not Dockerize a […]
In this short post you will learn how to make a cheap Grove 0.96″ OLED display module. In fact, it should end up costing you 4-6x less than the off-the-shelve product. Grove primer Just real quick in case you stumbled upon this post not exactly sure what you are looking for. Grove is a modular, […]
Look Creately, if you want me to use your service – which I really wanted to – then it is not a good idea to require dead technology from a past era. Adobe Flash is really dead. Has been for a long time. Its fate was sealed back in 2007(!) when Apple refused loading it […]
