My new PC is a Minisforum UM690S. Despite its small size, it is very powerful. However, the small computer has one drawback: the two case fans are quite loud and run at full speed constantly. Therefore, I opted for a small modification to replace the case fans.

The FireBeetle 2 ESP32-C6 board from DFROBOT is very affordable and integrates not only the ESP32-C6 but also a charge controller for charging a lithium-ion battery and monitoring battery voltage. In this article, I'll show you how to build a cost-effective sensor for the weather station using this board.

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.

So far I have used SquareLine Studio to create the weather station GUI. Unfortunately, SquareLine has now quadrupled its prices. So this company is no longer an option for future projects.
