Hi,
I am a Trekkie from Germany who loves to create new technological projects with Arduino, Raspberry Pi, robots, microcontrollers, electronics, 3D printers, and much more.
I want to share my experience, projects, and passion. Look at my page, explore many different technical projects, and leave a comment.
have fun

Sometimes a project starts with a single visual idea — and then it grows into multiple implementations, each teaching you something different. This one began as a fascination with “clock hands as pixels”: lots of Read more…
I built an Infinity Cube powered by an ESP8266 and NeoPixel LEDs. The result is a mesmerizing LED cube with multiple color modes, Wi-Fi control, and a clean 3D-printed enclosure.In this post, I’ll explain what Read more…
After my Wordclock 2.0 and Ringclock, I want to present my third clock, which has an ESP8266 and Neopixel-LED. I call it DigitalClock because I use NeoPixel-LEDs to display four seven-segment displays. LEDs also illuminate Read more…
Light up your space with this handmade star-shaped wooden lamp! It’s made with a jigsaw and a simple lamp socket from the hardware store. It’s fun and easy to create something unique! If you enjoyed Read more…
Hey folks! If you got a kick out of my Word Clock 2.0 build, you’re going to enjoy what’s up next. I’ve been tinkering away and am stoked to introduce the LED-RingClock. It’s another little Read more…
I am currently in the process of designing and building a five-axis robot from scratch. I, therefore, also need a gripper to be able to manipulate objects. The drive for the gripper should be a Read more…
In this post, I would like to summarize the steps to set up debugging of Raspberry Pi Pico with Picoprobe in VS Code on Windows. Most of this post is taken from other tutorials. See Read more…
This post is a complete guide on how to set up secure communication from a local Node-RED server to a server on the public internet using TLS-encrypted MQTT messages. In my concrete case, I have Read more…
I built a small project to test the Raspberry Pi Pico with the Pico LCD 1.3 module. This turns out to be a very nice gift for any person who sits in the office all Read more…
