I'd like the "Trusted" flag for user ishanpm. I mostly just want to update my rule's page at https://conwaylife.com/wiki/Rule:Pulse2 to match the one on my repository.

I made an extremely easy infinite minesweeper game this afternoon. Enjoy: https://ishanpm.github.io/easy-minesweeper/

Could you post an explanation of the rule and the cell states? It's not very clear from the examples, and the source code is a bit dense. The main obstacle to a Golly implementation seems to be the FloodErase function, but some trickery with timing could lead to a ruletable implementation.

one billionth of one percent is more than 100 million trillion Um, I don't think that's -- one billionth is one-thousandth of one percent, or one-thousandth of one percent OK, that's a little closer, but -- one billionth of one percent is just one thousandth of one percent Now you're just being rid...

I found a thing called Chemlambda. It is a graph-rewrite system capable of evaluating (most) lambda calculus expressions using only rewrites involving up to four nodes, using a technique resembling DNA replication. Here is the page: http://chorasimilarity.github.io/chemlambda-gui/ Here is a (work in...

Tree game validator! Let me know if you see any bugs.

Doesn't support fakeTREE at the moment. Later, I'll add a feature to list legal moves.

Shouldn't the player with no legal moves be the loser? That's how it is in the original article , anyway. Otherwise, there are only a few ways the game can play out. For TREE(3), there's a fairly simple winning (losing?) strategy for P1: P1 plays (). P2 then has a choice: []: P1 plays {{}}, P2 must ...

Do you also have something like that to convert signal to 0. Is this what you mean? You can make a device that forces the signal to 1 with two NANDs, then you can invert the output to get 0. Freywa's design for the bit padder contains one of these. x = 29, y = 9, rule = WireworldModern .2C$D2.B$B2....

Here is a version of the rule that is functionally identical, but uses extra states 9 - 28 to show what kind of logic gate each cell represents. Simply let a circuit run, and the cells where electrons interact will update their icons accordingly. @RULE WireworldModernTrace **************************...

Wow, that's a good design! That's a really nice use of the signal adders. I'm used to register-based designs, so I'd probably never think of something like this.

What is an ANT gate? Did you mean ANDNOT gate? Yeah, I mean ANDNOT. I've seen it referred to as ANT in a few places, but I can't find any examples. The way Wave handles logic is pretty interesting. Every gate is a 4 by 4 block of cells, with some flags on the corners that indicate whether each side...

Yay, my CA is kind of interesting! My mission is accomplished :D The QFT computer might not really be in CGOL, but there's just something that tickles me about writing a game of Tetris inside a language that compiles to a machine language that's run on a computer designed in a CA that's modeled in m...

That's certainly an odd message. That is the first place in the rule table where there are multiple consecutive spaces, aside from comments, so it might be a character encoding issue of some kind. Here's a version of the rule table without any consecutive spaces: @RULE TuringTumble A cellular automa...

What does the error message say?

Wait, blue overrides red? I would've thought it would check left to right. I checked the rule, and I guess I wrote the transitions for blue marbles before red marbles in most cases, although I can assure you it was a complete coincidence. Be warned that there is an exception: If two marbles land on ...

Here's an improved version of the board. It's a little more tightly built than the other one. You can stack marbles (or put a marble dispenser) onto the inverted gearbit on each side, and then manually trigger the marble releases by dropping a marble on one of the notches on the side. x = 17, y = 52...

Turing Tumble is a toy mechanical computer that can be configured with plastic pieces to perform various operations. As they mention on their webpage, it can count, add, subtract, multiply, divide, and do anything a normal computer can, "limited only by the size of the board". The board's pretty sm...

You can make a very tiny 3-tick generator:
I mostly use 6-tick logic in my designs, though. It's generally easier to send a bitstream with some extra space between the pulses.

This version has a large set, and the icons were generated with icon_exporter.py, so it should work. @RULE Pulse2 @TABLE neighborhood:vonNeumann n_states:18 symmetries:permute # 0 | none # 1 | gate on pulse # 2 | gate on cooldown # 3 | gate on # 4 | gate on through # 5 | gate on through cooldown # 6...

I made a page about the design and machine language: https://github.com/ishanpm/pulse-ca/wiki/Pulse2-processor All of your observations are correct. The tower in the upper left is a RAM node, communicating the same way the processors are. The red and green cells function very much like regular wires...

I am far from the first person to make a computer in a cellular automata, but I think I might be the first person to make one that supports multiple cores! The Pulse2 processor has a bounding box of 298x248, four 16-bit registers, and a 64-word read-only instruction memory. It also has four IO ports...

That sounds interesting! I can't really visualize what the larger grids would look like though... Can you post a pattern of it?
