Description About a year ago, I built a large E-Ink image display using a Raspberry Pi. While it worked well, the Raspberry Pi required relatively high power consumption, making battery operation impractical. When I discovered that a similar system could be built using an ESP microcontroller, I didn’t have to think twice. It was the perfect opportunity to revisit the project and create a much more power-efficient version. Project summary In this project, I converted my Raspbe

Description For years, I had been thinking about building my own drawing machine. Since I already had a collection of small stepper motors lying around, I finally decided it was time to turn the idea into reality and build one myself. Project summary In this project, I built a CNC drawing machine and experimented with several improvements to increase the drawing quality. However, after a number of iterations, I decided to stop the project because the achievable quality did no

Description I came across a commercial device that displays the next public transport departures for a specific stop. I don't really need something like this, however it looks quite nice and I thought I could easily build something similar myself. Project summary In this project, I adapted an existing display for use as a public transport departure tracker. The main focus was on software development and the design of a custom housing. My responsibilities CAD design and 3d pri

Description When I first saw the Carpentopod project I knew that I would like to build something similar. So the project started and I built a walking table. Project summary I designed and built a 6 leg robot that has a table form. Most parts are 3d printed and the modular design is utilized. The project's main challenge was the mechanical design and keeping the costs down. My responsibilities CAD design 3d printing and build up DC motor selection and control Programming and

Description This is definitely one of my longest private projects. Around 3 years ago I made one that had a lot of improvement possibilities. I took it as a challenge and in this project I tried to overcome the main issues I had with the previous one. Project summary In this project I built a flap display that can show different symbols on limited digits. My responsibilities CAD design 3d printing and building the display Programming and testing Results As this project was
