If someone thinks I like clocks of all kinds ... he might be right ;-)
 
 A clock project of the developer of the BASIC-Interpreter ANNEX32   for the ESP8266 / ESP32 with a MAX7219 display inspired me a little.
So I went back to my late childhood, spent a couple of hours gluing a model airplane together ... added some soldering work ... used the fabulous BASIC-Interpreter ANNEX32 ...  and ended up with this nice object.

The banner shows the time and some local online weather information from openweathermap.org and sits on a thin steel rod around which the second wire for the power supply runs.

I used an ESP32 for this - an ESP8266 will do the job as well.,
The dotmatrix display is made of  8 MAX7219 modules (4+4)

Some more detailed information  >HERE<

The code for the project runs in the BASIC-interpreter ANNEX32  . Find its documentation HERE.
