Makerfabs offers two new 7-inch displays with IPS panel and ESP32-S3 microcontroller. After my review, I realised that only one version actually has an IPS panel. The lower resolution display uses a TN panel and is similar to the Sunton 7-inch display.

In this article I would like to show you a small project on how I built an LED aquarium light from various leftovers. The brightness is automatically controlled by an ESP32 microcontroller.

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.

A tutorial for a weather station that can display the weather forecast, air quality and, using wireless sensors, the temperature, humidity and air pressure in several rooms.

The ESP32-S3 7 inch display from Sunton is one of the few boards that combines a modern microcontroller with a comparatively large display. I will show you how to get it up and running with just a few steps.

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.

The Raspberry Pi is now largely obsolete for me. It has become too expensive and completely oversized for many tasks anyway. Now the new generation of the Zyklochron is ready. Besides the microcontroller, some other things have also changed.

How can a headless device be connected to a WLAN network? One possibility is SmartConfig, which makes provisioning very easy via smartphone. With this library for the ESP32, you only need a few lines of code to connect the device to the network.

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.
