All Projects
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 small analog clocks arranged in a grid, where each clock has two hands that rotate 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 I built, how it works, and give you a step-by-step overview so you can rebuild 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 the dynamically changing background. Features of the clock: Content 1. Material for the DigitalClock with 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 our previous post on building a wooden lampshade, you’ll love this new design. For the 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 project that combines the cool glow of NeoPixel LEDs with the brains of an ESP8266 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 commercially available micro servo, as shown in the following picture. In addition, the gripper should 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 the references at the bottom of this page. I presume that you’re already familiar with 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 a Raspberry Pi running Node-RED to collect data from multiple sensors in my local network. 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 day. The device will remind every 30 minutes to drink water. You can connect it Read more
I developed a 3D-printed robotic hand during my studies at the Technical University of Munich. I used a 3D printer to build the mechanical parts and a Raspberry Pi Pico for controlling the motors. Background Every four years, ETH Zurich organizes the CYBATHLON competition (cybathlon.ethz.ch), in which teams from all Read more
