And of course, when everything was ready for the final integration test, the Lego motor broke down. 🫠

Disassembled everything and checked all cables, but it’s definitely the motor. The second one that broke, to be precise. Gud Lego kwalitee. 👌

I’m finally done with the new software. 873 ~~beautiful~~ lines of c/c++.

In forecast mode (FCS), the turbine rotates according to the predicted wind speed (it also shows the forecast for the next 6h). In timer mode, it rotates at full speed for ~1h.

It also displays the current temperature/humidity as measured by the white DHT sensor.

Most pixels are handcrafted and there are some "clever" solutions for a few problems.

But all in all, I'm so glad to be writing Python most of the time.

However, the e-paper display has been broken for more than a year now, the WiFi code stopped working even before that and the whole set was getting dusty.

So I took it back home, cleaned it and started to fix the code. I never programmed a micro computer and my C/C++ skills are rusty at best.

But with @zeratul2099's help, I quickly learned how this stuff works. It was a great feeling to light up an LED via a button. And it felt even better when I got the display to actually show something.
