"I create stuff."
Welcome to my blog where I mostly post things I've done over the years. Hopefully this will be a somewhat living archive of my adventures as a amateur maker and creator of mostly useless stuff.
During this latest DreamHack event here in Jönköping (DHW23) I did some small updates to the Alertsquarer previously featured here. SG had bought some new hardware so instead of three 32×32 panels there was now two 64×32 panels. So while fixing support for this, and doing some minor adjustments I also added support for loading […]
A friend at En Produktions Byrå was assigned to design a section of a Fagerhult exhibit for their permanent showroom located at the headquarters. The display consists of several clusters of buttons, resembling vintage radio buttons where only one can be active at a time in each group. A sophisticated display mounted on an adjacent […]
Quite a while ago I bought an IKEA Vindriktning air quality thingie on sale with the intention to connect it to my Home Assistant setup. It’s a quite simple affair, there is a RS232 TX pin on the Vindriktning board that spews out values, so just connect a ESP32 to that and push the values […]
After my second Ursa inspired keyboard was finished and I wasn’t completely satisfied with the bulky look I decided to leave fabric and go back to a material I’ve worked with a bit more, wood. Also my newest PCBs had arrived a while back and I was eager to use them. I’ve also gotten some […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
