Sorry, I didn't see your question

> And for the record, who created the original 'experiment from 2010'?

Own experiment.

Also, for the coming period it doesn't seem I'll have any time to upgrade LogicWorld

You beat me to it with a metacell, although it's a non-programmable one. I've seen and used self-feeding XOR gates before. I don't know why I haven't thought of it in this context. It's used in the WW primes computer as well as my recent WW clock. I too have been thinking that I don't like LW as muc...

The fastest togglers (Master-slave T-flip-flops) I can make are 42-tick. Is this the fastest they can get? I need them much faster, preferably 8-tick. Input is ≥4 gen, but as these will be cascaded, the input needs to support longer signals. The alternative is to use regular flip-flops (which requir...

I'm thinking about changing the 'color' of the crossovers (not the icons) to support icon-less viewers like the one here and on discord. How about desaturated shades of yellow?

I felt like redoing the slanted hexagonal icons with Antialiasing and gamma correction (works only on black background) For reference, here is Tim Hutton's attempt from 10 years ago: https://timhutton.github.io/2010/05/21/31455.html Z8lhZnA.png These XPM icons are uncompromised true-color gray-scale...

No but I'm investigating an extended version

I made a toy WireWorld variant where I could mark one photon with a different color and see where it ends up in the circuit. Useful for debugging. Just stick an F at the end of the name in the rule selection dialog to start following. Remove the F and marked photons just revert to Wire (because that...

Today I've implemented the CMOS 'gated D latch' from https://en.wikipedia.org/wiki/Pass_transistor_logic (without the inverter at the input) It seems the changes to the transistor were adequate, because it works out of the box. Essentially what this does is identical to the 'serial register circuit'...

I went through two more transistor design iterations because the old ones still didn't do everything they're supposed to. For example, they failed when applied as transmission gates. I found two problems: - Each input is split and directed to different logic. When the results are combined they were ...

I made a working "dynamic logic" D-flip-flop. This flip-flop is edge-triggered, and when the clock is stable, it stores the internal state in a 'floating' electrode, thus keeping a static charge while surrounding transistors are off. For more background on how this works, see this In order to make i...

5-inverter oscillator, period 3600. I noticed everything crashes when a burst of negative electrons enters the positive power rail and mixes with the positive power via the junctions, and keeps circulating through the circuit, accumulating more and more garbage until everything reads "+‒+‒" in chort...

NAND gate. We have proof of turing-completeness. As if that wsn't clear already. But it's good to see my logic work out as expected for once. The propagation delay of this gate (with indicator wires) is 1220 gens. This means at that gen you see the answer in the lightbulbs. x = 2142, y = 780, rule =...

New crossings because I realized the old ones don't preserve synchronicity (as delays differ between different signal turns) This is actually an adaption of an earlier more optimized crossing which had narrower wires. Since the longest past can't be shorter than than 90 gens, all paths must be 90 ge...

The P-type transistor turned out to be quite trivial. Just advance the photon extinguisher loop at the control input by 10 gens. Here it it together with the N-type transistor, and with more test cases and updated "artwork". (Reminder: set step size to 10 to make it look better) x = 319, y = 223, ru...

Challenge: come up with a sequence like Gijswijt's sequence with
1) an even harder name to spell and pronounce
2) a slower growth rate

Gijswijt is actually a Dutch person (or name at least, according to genealogy) and the pronunciation on that site is COMPLETELY WRONG.

I'm working on a technique in Wireworld to simulate CMOS technology from real-world electronics. It should embed entirely in classic WireWorld everyone knows and loves. Why? Because I can. BRAINSTORMING Making logic with wires which are one-directional, whether 'logic levels' or photons, is easy. Ho...

I just installed Golly for the first time in 2 years (and I've freed my mind and converted Ubuntu instead of Windows) and noticed this bug and found this thread. Moreover my version seems to be 2.8. Why is the repository giving me a 3½-year old version!? Never mind that, I uninstalled 2.8 and downlo...

Finally the administrators yielded and fixed the site certificate, despite that I complained via email several times in he past half year. Finally people can log in again without worries. I also don't know how long this issue persisted because it was half a year ago I wanted to log in again after a ...
