Middleweight emulator is a period-4 oscillator found by Robert Wainwright in June 1980.^[1] It is one of the three standard emulators and produces sparks similar to those of the middleweight spaceship. It is often used in the construction of larger oscillators, such as 145P20.

A four-fold version of this oscillator appeared semi-naturally in April 2016.^[2]
