Need your collective experience:
I want to keep a platelet exactly level, independent of the unpredictable circumstances it is in.
I have servos and Atmels to swim in, the programming will not be a problem, but I'm having trouble finding a decent electronic solution. I COULD attach a weight to a potentiometer, but that's too much work when I decide to reproduce the solution.
I am, however, fine with a plastic cubelet that contains a low-friction potentiometer and a weight prefabricated.
I need a good amount of accuracy if at all possible.
Searching "waterlevel" and "plummet" end in irrelevant results, for obvious reasons.
