I was thinking about building a self-assembled easy to use fraction collector controlled by raspberry.
A Fraction collector is a piece of equipment used in liquid chromatography which has some tubes or holes and moves every some time to the next tube / hole.
I was thinking about two servos one moving in X plane and one in Y plane but I don't know that piece of equipment would be the best - step motors, micro-servos or maybe even something else.
I would like to use python to program time required to gather single fraction and move one or the other servo X or Y position.
Could someone suggest me a good starting point?
