A few weekends ago, I built a Nest-like thermostat running on a Raspberry Pi Zero using Nim + Karax + some C code for Arduino temperature sensor modules.
By now, these Pi-based thermostats are nothing new but it was a really fun experience putting it all together with my son who's learning to program and hack around with electronics.

Thanks to all Nim contributors for creating such a nice language + ecosystem.
Wow, amazing!
Thank you very much for sharing your project milestone :)
