Life aboard a 23rd century starship is not without its troubles. Back then starship interiors were cramped and privacy was a rare luxury enjoyed mostly by the bridge-officers. So as to not be surprised by interlopers, Starfleet personnel were known to arm their com-panels with motion-sensors to alert a room’s occupant when their thresholds were breached. This replica of those very com-panels brings classic 23rd century design to the 21st century! The all-new Star Trek: The Original Series Electronic Door Chime has been updated from its original version; duplicating all of its original functionality with 4 new sounds, and new lighting effects. 23rd century duotronic circuitry and subspace transceivers, that technology is still a few hundred years away.
