All Projects
Here is one more small project I build on one weekend. the starting point was a spare “Raspberry Pi Blink!” mini LED strip originally planned for a Raspberry Pi. I wanted to build at least a little bit useful project with these eight LEDs. A seven-segment display is therefore perfect Read more…
In this article, I present my basic hardware and software parts for a smart LED lamp project, which is to be controlled via WiFi. Two examples of such a project are a decoration LED tube light and my newest word clock, which requests the time via the Internet and displays Read more…
Two years ago I already built a word clock with NeoPixel LEDs. You can find the article about it here. At that time I built the word clock only with an Arduino and queried the time via radio. But this time the plan is to make the clock bigger, prettier 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…
Design your own lamp? Not easier than that. Here is a step-by-step instruction on how I build my own DIY lamp from wood. For the DIY lampshade shown, we only need three materials: Wooden board 25x25cm – 18mm thick wooden stick 5x10mm – 20cm long some wood glue Step-by-step instructions 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…
This post summarizes the steps to program an ESP8266 with an own program written with Arduino IDE. I used the ESP8266 for example in the project MANU – 3D printed robot hand. Installation of Arduino IDE First, the latest version of the Arduino IDE needs to be downloaded and installed Read more…
In this article, I present the central concept of the robot control of my mobile robot. There are many different variants to structure the software for a robot. I will show you which one I implemented in MOBROB. Direct control The simplest option is the so-called direct control. Here, a Read more…
After I presented the hardware architecture in an earlier article, I want to dedicate this article to the software architecture of my mobile robot MOBROB. The software architecture is based on Robot Operating System (ROS), which allows me to extend the robot very modularly by functions. There are a lot Read more…
This time I will show how I built the LED light cubes shown in the picture above. I call them TinyLightCube, as they using an ATtiny85 as a microcontroller. The cubes will change their color depending on how they are tilted. Parts For one color cube we need following parts: Read more…
