I’m really happy with how my current project is going

This is an air quality sensor plugged into a microcontroller that’s transmitting readings over a mesh WiFi

I only have this one soldered at the moment, plus a prototype on a breadboard. That's my proof of concept that I could do this.

I learned lots doing this. Quite happy. Much to do still.
