ABSTRACT:
A module interposed between a slide tray and a projector provides a user selected random presentation of sequentially ordered slides. The module bottom simulates the tray bottom to align gates of the module and projector. The module top simulates the tray bottom to align gates of the tray and module. A microcontroller controls a lifter foot to keep unwanted slides from dropping into the module gate until the tray had been rotated by a hub assembly to the next desired slide position. The lifter foot then acts to lower a slide through the module to the lifter foot and projector, and return it after projection.
