We have not created the chamber from scratch - originally, we have received an earlier version (the author is unknown to us) for repairs. After inspecting it and trying to reverse-engineer the circuits, we have decided to modernize and simplify both the mechanical and electronic parts.

We removed the four top motors (extracted probably from acu-drills) that determined the dispenser position and replaced them by servo motors - both the mechanics and the electrical control is simplified. The original setup was controlled through a serial port and a series of complicated electronic parts which we discarded in favor of a Brmduino. We have made a new board for the door control, but reused a relay from the original circuit and re-used the same principle. | We removed the four top motors (extracted probably from acu-drills) that determined the dispenser position and replaced them by servo motors - both the mechanics and the electrical control is simplified.
