Blinker puffer 1 was the first blinker puffer to be found, and was discovered by Robert Wainwright in 1984.^[1] It consists of an unstable xWSS-like pattern being escorted by a middleweight spaceship and a heavyweight spaceship. The blinkers that it outputs can be burned cleanly by attaching a blinker fuse to the end of it, a technique that is used in the construction of moving sawtooth, sawtooth 1163, slow puffer 1 and slow puffer 2.

It produces blinkers of the same spacing as those produced by blinker puffer 2, so a blinker fuse can similarly be used with that puffer.

A symmetric version of this puffer appeared semi-naturally in November 2016.^[2]
