Prints of new brain enclosures…we considered putting the pump in a separate enclosure from the other electronics but opted to just add a wall.
We understand that the pump is going to receive abuse and encourage you to push its limits. Honestly, I would prefer to learn the impact of hard water on our system rather than encourage you to use only distilled. We chose a peristaltic pump because no part of it will come in direct contact with the liquid making it very tolerant of particulates. We expect that the first point of failure will be with the hose (silicone) itself - not with a mechanism within the pump - though we have not tested any of these until the point of failure.
