A beehive stopper is a Spartan logic circuit discovered by Tanner Jacobi on May 12, 2015.[1] It converts an input glider signal into a beehive, in such a way that the beehive can cleanly absorb a single glider from a perpendicular glider stream. The circuit can't be re-used until the beehive "bit" is cleared by the passage of at least one perpendicular input.
This term has sometimes been used for the beehive catalyst variant of SW-2, which uses a beehive to stop a Herschel -- and also for Paul Callahan's larger glider stopper, which also provides optional 0-degree and 180-degree glider outputs.
On January 25, 2022, Gustone discovered a beehive keeper with similar functionality,[2] but activated by an input Herschel instead of a glider. The keeper's beehive can stop gliders on lanes 3 cells apart, and therefore it supports reset signals using either glider color. As with any keeper, and unlike the beehive stopper, it is not necessary to remove the beehive keeper's "bit" before sending in a new input signal.
