So, something more "Earthly" for now:
For a project the idea is to replace this array of separate and not-too-reliable timers
and so, after fiddling with Python, an RPi 3B and an Arduino UNO I keep around, here is a generic programmable timer relay controller (specifically, 8 relays with a maximum of 12 activations per day for now), controllable through a 3.5 inch resisitive touch display:
After some testing the idea is to use an Arduino Nano and eventually a Pi Zero to package everything decently in a more compact box.
Since this would be used without an internet connection, a thing I have to figure out how to do is how to attach a real-time clock without using the GPIO pins, currently used by the display.
