How can you control higher loads such as LED strips with the ESP32 when a single GPIO pin can only deliver a few milliamps at 3.3 V? In this article, I take a practical look at different transistor solutions for switching higher currents with the ESP32. I compare a Darlington transistor with three MOSFETs and show, which types are suitable for logic-level control.

Microcontrollers with built-in Wi-Fi are still rare. Now the Raspberry Pi Foundation has introduced the Raspberry Pi Pico W, which addresses exactly this weakness. This makes the Raspberry Pi Pico W an interesting alternative to the ESP32.

I have always liked a tree trunk as a cat tree. Now I had the opportunity to use a dead apricot tree. The result is a very pretty cat tree. Here is a short description of how Einstein and Newton got their new cat tree.

Great excitement in the Botanical Garden of the University of Vienna. After three years the Amorphophallus titanum blooms for the first time in Vienna. Of course I had to see this rare event on the spot.
