A blinker fuse is any fuse that burns through a line of blinkers. Alternatively, it may refer to the 2c/3 period 18 fuse that burns cleanly through blinkers that are spaced four cells apart, shown to the right. This particular fuse can be combined with blinker puffer 1 to create various interesting patterns, such as moving sawtooth, slow puffer 1, and slow puffer 2.

Note

House alone, attached to a blinker wick with spacing 4, is a predecessor to the fuse shown to the right.

Other 2c/3 blinker fuses

There are two other well-known 2c/3 blinker fuses that act on blinkers that are orthogonally offset by four cells, both of which are shown below. They both burn cleanly and have period 6.[1]

4c/5 fuse

The 4c/5 fuse burns through alternating blinkers with the same spacing as the 2c/3 fuses. It was reported by Hugh Thompson in 1971.[2]

x = 34, y = 5, rule = B3/S23 29bo$o7bo7bo7bo3bo3b2o$o2b3o2bo2b3o2bo2b3o2bo2bo5bo$o7bo7bo7bo3bo3b2o$ 29bo! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]] #C [[ THUMBSIZE 2 ]]

c/2 fuse

The c/2 blinker fuse burns cleanly through blinkers that are orthogonally offset by an even number of cells and has period 2x spacing. HWSS burns clearly through output of both Blinker Puffers 1 and 2 and front part of Blinker ship 1.[3] It consists of a single heavyweight spaceship and is useful because it travels at the same speed as the known blinker puffers, allowing for the construction of arbitrary-length spaceships. Note that Coe ship's side spark can also be used in cleanup.

x = 28, y = 9, rule = b3/s23 b6o21b$o5bo21b$6bo21b$o4bo22b$2b2o24b2$3bo3bo3bo3bo3bo3bo3bo$3bo3bo3bo 3bo3bo3bo3bo$3bo3bo3bo3bo3bo3bo3bo! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]] #C [[ THUMBSIZE 2 ]]

6c/13 fuse

The 6c/13 blinker fuse burns cleanly through blinkers that are orthogonally offset by six cells and has period 26.[3] It is most well-known for the role that it plays in blinker ship 1, where the fact that it burns at a rate slower than c/2 is taken advantage of to create a growing spaceship.

In January 2021, INoMed constructed an adjustable high-period 3c/7 orthogonal puffer that repeatedly ignites this fuse.[4]

x = 62, y = 3, rule = b3/s23 3o4bo5bo5bo5bo5bo5bo5bo5bo5bo5bo$obo4bo5bo5bo5bo5bo5bo5bo5bo5bo5bo$3o 4bo5bo5bo5bo5bo5bo5bo5bo5bo5bo! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]] #C [[ THUMBSIZE 2 ZOOM 8.5 ]]

8c/21 fuse

Another blinker fuse which runs on the traffic light, similarly to the above fuse.

c/10 fuse

The c/10 blinker fuse burns cleanly through blinkers that are orthogonally offset. It consists of a single copperhead and can be used to create spaceships that grow very quickly.

x = 27, y = 10, rule = B3/S23 5bo$5bo$6bo2bo$4b3ob2obo$2o6b2ob2o$2o6b2ob2o$4b3ob2ob2obo3bo3bo3bo$6bo 2bo4bo3bo3bo3bo$5bo8bo3bo3bo3bo$5bo! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]] #C [[ THUMBSIZE 2 ]]

Diagonal blinker fuses

There is a diagonal blinker fuse involving a B-heptomino reacting with a line of blinkers.

x = 53, y = 48, rule = B3/S23 ob2o$3o$bo6$14b3o$bo$bo$bo9$26b3o$13bo$13bo$13bo9$38b3o$25bo$25bo$25bo 9$50b3o$37bo$37bo$37bo! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]] #C [[ THUMBSIZE 2 ZOOM 5 ]]

Block and glider can engage in a similar reaction, forming a glide-reflective 2c/44 diagonal blinker fuse.[5]

x = 29, y = 26, rule = B3/S23 20b3o3$17b3o8bo$28bo$28bo$14b3o8bo$25bo$25bo$11b3o8bo$22bo$22bo$8b3o8b o$19bo$19bo$5b3o8bo$16bo$16bo$2b3o8bo$13bo$13bo$10bo$10bo$2o8bo$obo$2b 2o! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]] #C [[ THUMBSIZE 2 ZOOM 8.5 ]]
