I smell like bananas.

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 [...]

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 [...]

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. [...]

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 [...]

After I received my new PCBs I wanted to get a feel for them and start using them as fast as possible. So I grabbed a 22mm thick sheet of MDF from the stack and started cutting in to it. For the tray to have a bit more strength I soaked it was watered down wood glue a couple of times before I painted it black. The result wasn't amazing, or above [...]

After the failure and lessons learned with the design and production of Lou1:d I didn't give up. And started working on Lou1:e. I decided to skip the extra column of switches to the left, my idea was that I could keep the wirings and add solder points for an external 5 row 1 column PCB if I wanted (spoiler: i didn't do it). Also I wanted to use more [...]

A couple of years ago I saw that a store sold Kobo eInk readers relativly cheap and a quick google showed that it was possible to root them and do what you wanted, so I bought one, and rooted it. Unfortunately there were no ready made scripts or programs to display weather information on the screen so I made my own. The first version At this time I [...]

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 [...]

After trying hand-wiring i decided that I wanted to try to make a custom PCB. This would be the first that was a bit more advanced, with a MCU and USB. I also wanted a PCB for the vintage SMK switches I just bought from Ebay. SMK gen2 switches I used EasyEDA to design it since i would be ordering from JLCPCB and there is a nice integration between [...]
