A private workshop
Tools, 3D printing, LoRaWAN and the weather over Sinsheim
What comes out of spare time: small programs that solve one concrete problem, free 3D models for private use, and a weather station writing things down every minute.

Who or what is CheetahLab?
Why this site exists, what goes on it and what does not: live data from a weather station and a LoRaWAN gateway, tools born out of building automation, designs for the 3D printer — and the detours that led there.
