Is this p12 sparker/eater known?

I was experimenting with a known p12 traffic light shuttle, and when I made it push a beehive, I noticed that it can eat a dot and a block:

I didn't see it in the sparker stamp collection.

I know that traffic light shuttles and beehive/loaf mechanisms can make more sparkers, like what I did with my newest p11 domino sparker, so what other low-period reactions or rephasable-looking mechanisms can be turned into useful sparkers? So far I know the beehive/loaf, interchange, sandwich, bi-block reaction, grin, pipsquirter catalyst, the reaction in the p16 beehive hassler, ship+eater, and two-blinkers-to-domino reaction are useful low-period reactions.

in Weak Dot, there is this variant:

I noticed that a B can turn into the same traffic light predecessor in my p10 pi hassler, and then noticed that a block that just got eaten can actually turn it back! The hassler is almost rephasable at p11. It just needs a good dot sparker or other reaction:

However, because p11 doesn't allow for gliders, really, and even though this is a novel way to turn a traffic light sequence into itself, the eater doesn't give much room to turn it back, so I still like the way you discovered, 8than888.

This is my first p17 discovery, and it might even be reducible! It's based on this accidental traffic light-to-century reaction:

Code: Select all

x = 10, y = 11, rule = B3/S23
b2o$2bo$bo$b2o$3bo$b3o3b2o$o6b2o$2o$7b2o$7b3o$7b2o!

And I tried making an oscillator using this reaction by turning the century into a pi predecessor and catalyzing the block to make the traffic light. I almost got a p16 oscillator, but I couldn't find anything that fit for the block:

Code: Select all

x = 31, y = 21, rule = B3/S23

2ob2o4bo3bo$bo3bo9bo4bo2b3obo$3obo19b3o$b3o12bo8bo$2bo$18bo2bo$18b2o!

Then I noticed that a grin in a different location can turn the century back into the traffic light at p17, which made me realize that it was actually completable!

Edit: I just found a p15 century/traffic light hassler!

Code: Select all

x = 27, y = 20, rule = B3/S23

It uses the same reaction, but the snake bridge eater is replaced with a p3 toad.
