Get HyperPixel 4.0 working horizontally for Octodash
Recently I managed to corrupt my Octopi SD-card by pulling the power plug while it was updating. Everything was up and running again relatively quickly, but one thing I could not get to work -no matter what I tried- was horizontal screen orientation for my Pimoroni Hyperpixel 4.0 display and OctoDash. Finally, I got it […]

Troubleshooting the Prusa MMU2S
3D printing in one color is fantastic—3D printing in five colors is the next frontier. Ever since I started my 3D printing adventure, I’d wanted to buy a Multi-Material Upgrade, but I was hesitant after reading some reviews. Many people seem to be having trouble getting the unit to function, and that’s no surprise given […]

Adding a copyright notice to an Apollo GraphQL API
You’re building an open API, but you want to make sure your copyright notice is displayed alongside the data? While building the backend for our rock photography website, I faced the same problem. I want hobbyists and tinkerers to be able to play with our API, but I want to clarify the copyright terms. We […]

Review: my first week with AirPods Max
One of the things I started to neglect during the lockdown is listening to music. When I still had to drive to work every day, I listened to a lot of music during my commute and in our noisy office. But now that there’s no need for commuting, and my desk is usually silent, it […]

OctoPrint: extra muscles for your 3D printer
It’s been almost two months since I installed my Prusa i3 MK3S+, and I’m still happy as can be. One thing that might scare off people who will buy a 3D printer (especially at Prusa) is the rather spartan user interface. The Prusa i3 runs on an 8-bit microcontroller, which is highly specialized but does […]

Building a 3D printer: the Prusa i3 MK3S+
It’s been on my wishlist for a long time: a 3D printer. Every time I put an ugly microcontroller somewhere in the house, I thought, “How crazy would it be if I could print a nice enclosure right now?”. After doing some spring cleaning, we suddenly had some extra space in our house. This space […]

Creating a native Next.js app with Capacitor
Next.js is my favorite JavaScript framework. It allows you to quickly build fully functional React-powered websites with amazing routing, support for SSR, and an excellent developer experience. Next.js is also a great tool to build mobile experiences. Combined with a component library such as Material UI, you can create web apps that feel (almost) native. […]

Review: Roborock H6 – a cheaper alternative to Dyson
Update: After about half a year, our Roborock H6 started to sputter. At first, he made a very high-pitched noise. Then he didn’t do anything. An inspection revealed that the printed circuit board that controls everything was extremely dusty and was not protected with a special coating as usual. Clearly a cost-saving operation, so I […]

Home Assistant: turning your home into a smart home
Recently I wrote about driving a lot of LEDs, ESPHome, and how our home network works. In each of those posts, there was a mention of Home Assistant. But what exactly is Home Assistant? Open-source home automation software Once you have intelligent devices in your home, you can’t get around: it’s a mess of different […]

Creating a digital dice with an M5Core
Our eldest daughter Janne loves this game called Bunny Hop. This is a game where you take turns drawing cards and advancing the number of squares on them. There is a lot of mayhem going on while you advance your Bunny towards the end. This is a great game, with one big frustration: those cards. […]

About giraffes, pandemics, and video games
In every top 100 video games of all time list, The Last Of Us scores very high. I bought this game for PlayStation 3 the day it came out. But in 2013, I was way busier with partying than sitting at home, and I never really got into it. I played the first hour or […]

A house full of sensors with ESPHome
These days you can waste a lot of money on smart appliances. Or make such smart devices yourself. ESP As I said in my previous article about our staircase with 600 LEDs, Espressif ESP boards are ideal for when you want to make things that connect to the Internet: Luckily other development boards are very […]
