@aislerhq@aisler.social I built a litter tray on a load cell for my old cat that had several issues and I wanted to track his weight. It's just two wooden panels with the load cells that are placed under the litter box and an ESP32 S2 based PCB with some parts for the load cell, a display and a knob. I also added a buzzer, so it always plays a nice melody when the cat did its business 🐈️ 💩 🤣
The measurements are stored in a CSV file on the ESP32's flash memory and can be displayed with the webserver that runs on the microcontroller.

@aislerhq@aisler.social I also built a remote cat feeder control button for our new cat so it gets some exercise 😆 One ESP32 in a button that sends a signal via bluetooth to the feeder that releases some treats for her. The feeder is upstairs, so she has to walk a bit 😄 It's still on prototype boards because it works well enough and there was no need to make a PCB for it (for now).

@fehlfarbe@dresden.network @aislerhq@aisler.social why not also measure the weight of what is left behind?
