Eater plug (or cavity[1]) is an extensible period-2 oscillator that was found in February 1973 by Robert Wainwright.[2] Its name derives from its resemblance to two diagonally-touching eater 1s.

It has an identical rotor to the great on-off, which is interestingly over 1000 times more common than it despite its size.
Commonness
Eater plug is about the fifty-fifth most common naturally-occurring oscillator in Achim Flammenkamp's census.[3]
gollark: Well, it means you don't have manufacturer bloat. That's one problem of many.
gollark: Android One solves not many of my problems with Android.
gollark: <@581484526925250570> BlackBerry is very niche still and doesn't really allow rooting.
gollark: That matches Yes, yes, y and Y.
