"I create stuff."

A friend who works at Dreamhack asked me if I had any 24 led Neopixel-rings in my large store of good-to-have stuff. Unfortunately I didn't, I could only find 12 led ones. In the crew area for the tech/network crew at Dreamhack in Jönköping they have had a display that show the number of active alerts per team. So anyone easily could see if any area had problems, or if everything was green. The display consisted of four 24-led Neopixel rings that either was green for no active alerts, or show [...]

After the immeasurable success with the first case and the fact that I have computers both at home and work, and can't be bothered to transport a keyboard back and forth I decided to create one more. Since I had more Lou1:e PCBs and just got a new keycap set it was a natural choice to just continue working on modifying Andreas Chlupkas original design. The final result I did like the look and feel of fabric on the keyboard but wanted it a bit more fluffy, and I wanted to colour match the the case [...]

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. So I designed and printed a simple case for it with a 5V 4010 fan. The fan is connected to PiJuice and a small python script that uses the temperature [...]

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 key to change it and check for unauthorized access. Instead we create one ssh-key for each client-server pair. In theory Say you have a client and [...]

How I built a self-organizing distributed network of IRC-bots for a good cause. The bot called Landlady is just the last one in a long line of bots written in Perl, Python and Javascript. Why did you create this IRC-bot? For a couple of years I was given the task to handle the #dreamhack IRC-channel on quakenet. Between events it was quite a quiet place but during the early 2000s it became the largest channel on Quakenet for the days during the event. The number of users in the channel naturally [...]

I've been looking for a CMS to create my new website in. I would like something that i could run locally and just "compile" to static html that could be rsynced to a remote server. My main reasoning behind this is that I can't be bothered to have a Wordpress site that needs attention, constant upgrading and poses a security threat in any way. For the last couple of years I've looked at Jekyll and Hyde and all reasonable alternatives available but non of them was to my liking. It they was all full [...]

For a project I'm working on I wanted to test to oxidize copper to get it to look old and used so I read up on the internet and got some ideas. So I got hold of the chemicals I wanted to test with. Ammonia Table salt (fine, flake and coarse) Hydrochloric Acid Citric Acid Some texts indicated that you could apply Ammonia get the oxidizing to start of and add acid and salt to speed up the process and improve the patterns. The first three tests I performed was to soak a bit of paper towel in ammonia [...]

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 took the ferry over each morning and evening. A new find this event was the excellent Gulf station just by the harbor from where we each morning [...]

After I've used my Lou1:e PCBs a while and I had some ideas for a PCB that was more suited for experimenting with crazy designs I started thinking about creating a new version. After talking to the user 4pplet on the Mechanical Keyboard Sweden discord I decided that STM32 had just what I wanted, a lot of extra IO pins and a somewhat beefy processor. I ended up using the STM32F072 since it requires very few external components, it even has a built-in oscillator. Version 1.0 of the PCB With all those [...]

After my failure with Lou:1c – my first keyboard and after the new PCBs arrived I started with a case to go with the PCB. Design inspiration I started designing several versions, and even halfway built some before I finally saw an image in a Discord channel. The image had no attribution but there was a name on the keyboard itself that pointed me towards Project Ursa, a project to create a keycap with "a deep dish spherical touch area with a flat top edge" by Andreas Chlupka. You can view more of [...]
