All my projects with Raspberry Pi.
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…
This project is part of a larger project to collect and visualize data from a heating system in my house. The heating system consists of several heating sources (wood, heat pump, solar system, and oil) and two large heating circuits (two buildings). In this post, I would like to present Read more…
In this post, I shortly describe how to install Docker on Raspberry Pi 4 running Raspian Buster. There are many tutorials available describing the process, but I faced always an error when trying to install Docker on my Raspberry Pi 4. So I share here how I got Docker finally Read more…
In this article, I document the few steps necessary to control the Wi-Fi switch Shelly 1 with a Siemens LOGO! 8. For this we use the help of the tool Node-RED, which is described on the own website as follows and is therefore perfectly suited for our use-case: Node-RED is Read more…
With this post, I want to start with the description of the software for my mobile robot. One of the first things I’m setting up in the software is an OTA (Over the Air) update function for all my components on the robot. That means besides the Raspberry Pi, I Read more…
After a long time has passed, here is an update on the current major project MOBROB. My completely self-built mobile robot. In the last post, I introduced the basic functions. The next step is to place the complete electronics nicely on the robot, so that there is still enough space Read more…
Table of Contents Introduction Java-Application Python TCP Server on Raspberry Pi Result: Stream video from Raspberry Pi to Java-Application During the development of my mobile robot, I was confronted with the problem of how to transmit the video stream of the robots webcam to my central Java-Application. The structure looks Read more…
