I am about to embark a project where I need to pump high viscosity liquid, like thick mud, 2-3 meters up from a container and let it very slowly run back over a sharply tilted wall.
It should be a very slow pace. The motor noise has to be very low.
I need to be able to adjust the speed from either a (simple) control panel or serially from a computer. This is the easy part.
I figure I either have to use something like a slurry pump or build something with "buckets" on a belt.
Does it sound odd? It is for an art project.
What motors or pumps could I use and what is the best way to interface them with the arduino?
Any help that can make me proceed is really appreciated.
Thats a great idea (Archimedes screw)! I should be able to prototype that quite easily. Either 3d print something or just a hose around a pipe. I am planning doing some smaller prototypes first. 1x1 meter or even smaller.
I need to be able to adjust the speed of the flow. I will trigger/modulate electronic sounds with sensors detecting the speed and thickness of the mud when it passes certain areas on the wall. I will need to be able to adjust the speed of the motor depending on how the sounds act. This may need to happen dynamically, automated.
