Oscillator Discussion Thread

[8than888]

I have another lead related to the p11 pipsquirter.

While looking through 2c/3 wire fizzles, I found a double-length 2c/3 fizzle with a phase that looks very similar to one of the active phases of the Pipsquirter 1 variant on the LifeWiki. Normally this fizzle is terminated by a block, but removing the block instead produces a temporary glider that might even be useful.

This caught my attention because the fizzle is compatible with the known p11 double-length 2c/3 wire signal injector, so it seems like the remaining challenge is modifying the fizzle itself.

Here's the comparison (fizzle on the left, Pipsquirter 1 variant on the right):

I still haven't been able to turn it into a pipsquirter, but it seems like a promising direction. Does this reaction look familiar, or has anyone explored something similar before?

The idea reminded me of XWSS emulators, which can be viewed as a stabilization of this "line agar"

I've seen some line agars stabilized as spaceships before, but is there a general technique to turn these into infinitely extendable sparkers? There seem to be infinitely many possibilities!

[Entity Valkyrie 2]

Found a new? way to create toad-type catalysts, by using an oscillator that normally produces a grin and replacing the block with a boat, causing it to turn into a tub in such a way that it produces the 1-to-2 surface for a toad-type catalysis. Then, a domino sparker converts the tub back into a boat.

Here is the first example I found, involving a Coe's p8 and a figure eight:

Code: Select all

x = 15, y = 13, rule = B3/S23

Here is a p7 version, using a p7 regenerative loop grin and a moderate domino sparker:

Code: Select all

x = 25, y = 19, rule = B3/S23

Note that this p7 toad can survive some catalyses that the usual one can't:

I wonder whether oscillating "line agars" like this P5 can be stabilized into infinitely extendable sparkers

Code: Select all

x = 16, y = 24, rule = B3/S23:T16,0

The idea reminded me of XWSS emulators, which can be viewed as a stabilization of this "line agar"

I've seen some line agars stabilized as spaceships before, but is there a general technique to turn these into infinitely extendable sparkers? There seem to be infinitely many possibilities!

Yeah, so in this vein, can this easily be stabilized on the sides? We already have p4 and p8 superstring wicks stabilized into sparkers.

I checked, and there was an infinite version of the p8 one, though I am not surprised:

And no, I don't think the p6 domino fountain counts.

[WhiteHawk]

p54 (hybrid of 48 and 60); 60 is known but 48 is also incomplete. Honey farm, offset (4,0) from the obvious center. The domino spark must be just a domino and nothing else; anything "behind" the domino will cause it to fail.

This feels like it must have a smaller completion, but the hassler sabotages all the sparkers I tried (except for p6, which instead "only" destroys the hassler).

Resurrecting with a technically smaller completion using the new p27 gun. Would still like a non-gun completion, though

The bottom catalyst is the only problem. I've experimented with it quite a bit already though.

Edit: in the shuttle, there is an 11,3 push and a failed 8,3 push which uses a -3 phase-shifting reaction, and I know this is not really a traffic light hassler but I just found out there's this reaction that does the same thing, but only accepts a specific predecessor

The object can vary, but the yellow cells need to exist, and the white cell needs to border three other alive cells

[8than888]

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.
