A personal projects blog
I’ve been running a Proxmox cluster called Labparvum for years now, hosting everything from a private streaming service to infrastructure monitoring. Recently I added the piece I’ve had the most fun with: a fully self-hosted AI assistant running entirely on my own hardware. No cloud, no API keys, no per-token
I’ve been working on building my own X-ray machine to image objects and determine their internal geometry without destructive testing. This project is still a work in progress, but I wanted to share some of my progress so far. I’m using this post for my own documentation as well, so
To reduce electricity costs I wanted a solar and home battery installation.Since the quotes we received were quite high at around €14.000 I decided to build it myself. For €7.000 I was able to build an equivalent installation with higher quality components. A great deal of my knowledge and experience
Any person working with electronics, either for hobby or professionally will have a large assortment of components and parts laying around.I’d encourage anyone that will keep any kind of inventory of parts to invest some time in creating a system to keep track of the components you have, the location,
I created a sensor board that could monitor the air quality with a high degree of accuracy and sense many different pollutants and gasses, this is still a work in progress but ill share what I have already created. Specification Using the MICS6814 a whole range of other gasses can
To monitor the power usage of many of my devices I started looking into smart plugs and came across the “Shelly plug S” advantages of this model: disadvantages: How to program? Opening it is easy, there is a screw hidden inside the ground plug, unscrew this and the front pops
I wanted a power monitor with high accuracy and fast update speed, but could not find a solution that I liked so I set out to design my own.Using the ATM90E32 I made a 3-channel voltage/current and power sensor with high accuracy and very fast update speed. Specifications: Some improvements
To better monitor my solar power installation, I have been designing a few boards that can measure and control everything. This project was eventually abandoned and replaced with a victron installation, but I still want to share what I made so far
For a school project me and some other students were tasked with making and driving a CNC machine with our own hardware and software. I will only be posting the hardware here since that was my task.I designed 3 PCB’s-Powerboard-microcontroller board-stepper motor driver board To keep the cost low the

One of the problems with running a lot of equipment day and night is the power consumption and the cost attached. To mitigate this I wanted to produce my own power. I set my budget for the project to be around 1500 euros at first, but in the end it
Because I host a few websites, a private streaming service, a personal finance dashboard, and I like working with server gear, I built myself a small server rack. The hardware I currently have 4 nodes working in a cluster.1 powerful node (Gallifrey) and 3 low-power nodes (Atom01, 02, 03).The nodes
I had to create a simple 9V power supply for an electronics class in college.But because I found this a bit too simple and boring I decided to make it more interesting by making my own PCB’s for it instead of ordering one from JLC or making it on a
For my last year of high school I build a fusor, a type of fusion reactor. For now I will only put the pictures and documents here and go more into depth later.You can read my GIP bundel for more details but this is written in dutch.
For my projects involving chemicals, I needed some test tubes and something to store them in.I made 2 versions, 1 with plastic tubes that are actually plastic bottle prefabs(A plastic bottle before it is blown into the right shape). And 1 version with glass test tubes, the glass tubes were
In 1986 the worst nuclear accident happened in Chernobyl near the city of Pripyat. I have had a huge interest in this incident for a long time and so wanted to visit the place itself.In 2018 I finally had the chance to go there on a trip of 2 days
In need of some nitric acid and lacking the required chemicals I found out about the Birkeland–Eyde process.By creating a high voltage arc in normal air a few chemical reactions occur because of the hot plasma.Firstly the oxygen and nitrogen react to form nitric oxide.(N₂ + O₂ –> 2NO)While cooling
