"Having unpredictable outcomes and, in the ideal case, all outcomes equally probable."

This is random posts, anything that I want to share with the world and which don't fit into the other categories. It can be anything from pre-experiment tests to one-off ideas that I probably won't do more work on.

For quite a while I have been annoyed that I didn't have a phone stand for my phone that would charge it wireless. But then I remembered that I had an old wireless charger that I didn't use any more. The evolution of the stand The first crude version had a design flaw, I had not accounted for the precise positioning needed for the wireless charger [...]

I have a water radiator on my top floor mounted in a small niche, so small that there is only about 1cm of space between the air-valve and the wall. The problem has been that I since I moved here 10 years ago have been looking for something that would fit so I could air out the radiator. But it seems like the closest I found was some image of one. [...]

I have a Raspberry PI in the boot of my car, and it can get quite warm during the summer months, so it needed some cooling. The problem is that it features a PiJuice, to be able to handle the power being cut as soon as the car is turned off. But I couldn't find any cases that had place for both a fan and pijuice, even if i Googled for at least 30s. [...]

I have a handful servers where I login regularly and started to created separate ssh-keys for each client-server pair instead of the standard practice of just one ssh-key per client. The basic idea If you only have one ssh-key and it get accidentally (or intentionally by your nemesis) it's quite a chore to hunt down all the places where you used that [...]

This summer me and some of my friends continued the tradition of over 20 years now to go to Netherlands and visit the hacker festival known under new name each event. This iteration was called May Contain Hackers or MCH2022. This was the first time we didn't sleep in a tent on the campgrounds but instead lived in the lovely hotel across the canal and [...]

While designing my own PCB I created some prototypes. To test my designs and the capabilities of JLCPCB. I wanted to test the newly created footprints, colours and silk-screen prints among other things. So here are a small gallery of those prototypes. The first, mainly footprint test The 2nd & 3rd, more footprints The 4th, different sized holes [...]

I got a small vacuum pump to use with my projects using resin, and ofcourse me and the kids first task was to test to put different kinds of candy in it. https://youtu.be/jGdmLLrSNV8 https://youtube.com/shorts/ObA4UA7Tq50?feature=share https://youtu.be/4kXskGUJrmk https://youtu.be/fhccxxpRgLM https://youtube.com/shorts/4K-97uQMPw0?feature=share [...]

For many years I've enjoyed creating timelapses. The earliest i still have is from Dreamhack 2002. Since then there I've takes a lot more timelapses, mainly sunsets and stars. https://www.youtube.com/embed/4PJjDDDmT3s Dreamhack 2002 The 2002 Dreamhack one used my parents old VHS camcorder as a video device connected to an old dual pentium 200. After [...]

I have a FLIR ONE infrared camera that attaches to my phone. When I just got it I took it for a test and went out in the pitch black forest behind the house. And I was not alone. https://www.youtube.com/embed/DWdGXn6yoNE [...]

There're was quite a lot questions about how the effects in Illusions was created. Some guessed that we created a new flow-dynamics algorithm others had even stranger ideas. So here's a quick post about the process that finally led us to the effects in the video. First, it's all real fluids that anyone has in the fridge, into ordinary cold water. [...]
