Motorisation of a basic 1.25" filterwheel, using cheap 28BYJ48 stepper motor and hall sensor for precise positionment.
Designed to be printed in PLA. There is a gear for reduction to the already reduced stepper, so it is really precise. Using a stepper allows to not use any current when the wheel is at its target position.
The whole thing is driven by an arduino Nano, connected to the filterwheel using a RJ45 cable.
This requires drilling two 3mm holes for fixation, and gluing a big wheel ar
