The TMC2208 stepper motor driver from Trinamic is considered the reference as far as noise is concerned. Therefore I have developed a component for the ESP32, with which the TMC2208 can be controlled very easily via the UART interface.

Logging is one of the most important tools in software development. The Espressif IoT Development Framework offers a library for this purpose that logs to the UART interface by default. A setting allows the logs to be displayed in color.

With this component you can use the ESP32 microcontroller to find the time zone based on GPS coordinates. The required offline database is generated by a Java program and then stored on a flash chip.

Real hardware debugging with the ESP32 requires a JTAG debugger. This means that two USB ports are used on the PC. But it also works with only one USB connection.

The Raspberry PI does not have a battery-backed clock. Without a network, you therefore have neither the current time nor the current date. With a NEO-6M GPS module and a Python script, however, you can also get the time via the navigation system.

The Logitech Media Server, formerly also called Squeezebox Server, is the heart of the Squeezebox ecosystem. In this tutorial I describe the installation on a Raspberry 3B+ including a small display.

Until recently, I didn't even know about the existence of the Raspberry Pi 3 Model A+ and I don't think I'm the only one. It meets my needs perfectly and costs less than the Model B+. Therefore, I will rather use the Model A+ in the future.

Photographing water drops doesn't have to be difficult. With my new control device, it's easy to take beautiful drop on drop photos thanks to the touch screen. Just plug in your camera, flash and valves and go.

The clock has been running for quite a while now without any problems. However, one small thing still bothers me. The Hall sensors tend to oscillate. Therefore, I have redesigned the electronics from scratch.

Since Photoshop 2021, unfortunately, the errors are increasing. Here is a small overview, which bugs I noticed in the last days. But there is also good news. You can also just install the old version.
