Making

We have a cage for rabbits that we has small plastic hasps that somehow have a tendency to disappear. So on request from my wife I created a handful new ones. Original (white) vs. 3d-printed (green) After a couple of minutes in Fusion360, and 15 minutes in the printer we had a result, and it worked as well, if not better, than the original. Fusion [...]

For one of my children I created a small sign that said Roblox and I really liked the aesthetics of it so I created a larger version with built in light. From the start I maximized the size of the letters according to the printable volume on my 3d-printer. But the printing took ages, and it was close to 400g material per letter so I scaled it down [...]

In our office we have a suspended ceiling that we wanted to attach stuff to. Firstly we wanted a curtain rod to partition off a bit of the open plan. And later two small lights for a disco ball! First version, intended for curtain rod The first version worked quite well for the curtain rod, a couple of the small hooks got broken off but I made plenty [...]

After three [1, 2, 3] Ursa inspired keyboards it was time to try to do something different. For a while now I've seen several keyboards inspired by the original C64 design and colours, but I wasn't a Commodore guy, I had an Atari STe when I was a kid. The first ideas and sketches started to form properly around the start of the year, but it would [...]

I have a handful of cheap ESP32 development boards, and some expensive, that all sometimes gives me the error A fatal error occurred: Could not open COM6, the port doesn't exist. But I have found a workaround. The simplest way I found is to start with opening the Serial Monitor (in Arduino IDE) to see the status of the com-port easily. Then unplug [...]

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. [...]

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 wall is controlled [...]

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 to MQTT. There's quite a lot of guides online that are [...]

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 LOTR themed keycaps, more specifically the dwarvish set from [...]
