Sparkers

[Entity Valkyrie 2]

I'm looking for low repeat time catalysts (usually p1 still lifes but oscillating catalysts are okay if they can phase-shift) that can repeatedly produce sparks. Some examples I already know are the Two-blinkers-to-domino, this Eater 3-like catalyst used in the Pipsquirter article, and a higher-repeat time Thumb regularly called "Drifty Eater 3". Does anyone know of useful examples besides these ones?

I'm also looking for phase-shifting catalysts, which can help construct more oscillators for underexplored periods.

There's of course the long boat spin, which takes in a blinker and produces a middleweight spark:

Code: Select all

x = 12, y = 10, rule = B3/S23
2bo3b2o$2bo2bobo$2bobobo$5bo4b2o$10b2o2$2b2o$3bo$3o$o!

As for phase-shifting catalysts, here is a relatively recent catalyst that shifts the phase to 6n+5:

Code: Select all

x = 14, y = 14, rule = B3/S23

Here's another 6n+5 reaction:

Code: Select all

x = 14, y = 11, rule = B3/S23

2o2b2o$4bobo3bobo$4bobo5bo$5bo6b2o!

There's of course also the p5 phase shifter, which shifts the phase to 5n+3:

Code: Select all

x = 15, y = 12, rule = B3/S23

Could it be considered a HF shuttle with offset (3,2)? If so, it might be the first with that offset (I can't find any with that offset in the collection in LifeWiki).

I've been working on a p11 pipsquirter partial for months now. After exploring many different mechanisms, I've come very close to completing the pipsquirter multiple times now, but it kept failing. I'm posting these partials in the hope that someone recognizes a useful reaction or has search results that could help.

I found an activation that directly activates the pipsquirter using a traffic-light predecessor. It leaves a blinker which I tried to turn back. And these get extremely close, but the reaction can't recover.

Code: Select all

A more completable activation (pipsquirter replaced with eater 3):

Code: Select all

x = 21, y = 23, rule = B3/S23

I also tried a more different and more stable version:

Code: Select all

I tried to phase-shift a billiard table to activate the pipsquirter. I just haven't found a way to rephase it again:

Code: Select all

x = 25, y = 25, rule = B3/S23
b2o7b2o2b2o$bo2b2o5bo2bo$2b2o2bo3bo4bo$3bobobo2b2o2b2o$bobo3b3o2bo3b2o

There's another way to activate it with a traffic light but it dies after activating, so I tried to turn it back after 11 generations using a dying spark. It seems to be only producable asymmetrically though, it might just need a better p11 domino sparker

Any ideas, catalysts, recovery reactions, helpful p11 oscillators, or search results would be greatly appreciated. Even if one of these is only useful as a stepping stone, I'd be happy to know.

I'm looking for low repeat time catalysts (usually p1 still lifes but oscillating catalysts are okay if they can phase-shift) that can repeatedly produce sparks. Some examples I already know are the Two-blinkers-to-domino, this Eater 3-like catalyst used in the Pipsquirter article, and a higher-repeat time Thumb regularly called "Drifty Eater 3". Does anyone know of useful examples besides these ones?

I'm also looking for phase-shifting catalysts, which can help construct more oscillators for underexplored periods.

This is actually an extendible strictly volatile oscillator. The wiki page on volatility says that phonieces and self-constructing circuitry are the only infinite families of strictly volatile oscillator. That needs updated.
Speedydelete just found p30 family of extendible strictly volatile oscillator!

I just found this works also.
So maybe the wiki page is just out of date.
