I was working on something along the same lines, but without the eaters -- seems like those would get in the way of reconstruction, or at least slow down the repeat time since a lot of gliders would have to cross the fireship lane.

With a ten-minute investigation I could only come up with a four-object proof of concept:

Code: Select all

x = 21, y = 69, rule = B3/S23

A detector -- preferably using an easier-to-construct bait than either this or the block-on-table, if someone can dig one up -- would split the output signal(s) as necessary, to rebuild the bait and send a timed glider forward to demote the fireship to a copperhead.

Theoretically a bait object with only one protruding cell will also interact with the fireship's sparks, slightly later, but everything I tried destroyed the fireship pretty quickly -- at least with no further catalysts added.

Is there a synthesis that would allow "firing up" a copperhead after it's already in motion? That would require a much uglier converter, though, since I don't think there are any Heisenburp options available for a plain copperhead. (?)

Even if a stable Heisenburp-type reaction could be found, it would probably be just as easy to use a nice simple copperhead-to-glider converter, and then wire up a glider-to-fireship. There's also a fireship-to-glider, but I think for that case the Heisenburp approach will probably be a little more reasonable than rebuilding an entire copperhead.

This produces a sideways HWSS from a block on ship with catalyzing tub (unfortunately, the tub, which becomes a boat, later gets in the way of the fireship, but only just):

Well, here's a potential starting bait that should serve as an improvement over the previously shared ones, seeing that it only needs a bi-block and a ship to be reconstructed: Code: Select all x = 21, y = 25, rule = B3/S23 13b2o$12bobo$13bo3$11b2ob2o$11b2ob2o2b2o$2b4o12bobo$19b2o$2bo2bo$bob2o bo$bo4bo2$bo4bo$b2o2b2o$b6o$2bo2bo$3b2o$3b2o2$2o4b2o$2o4b2o$2o4b2o2$2b

The ship itself is only there to convert a rapidly formed blinker into a plume that lends itself more readily to forming a workable output.

EDIT: Actually, don't bother with that last bait, here's an even easier bait with an immediate B output:

That's certainly workable, with a slow-salvo reconstruction if nothing else. It would be nice if the output glider didn't have to cross the fireship lane, but actually that has advantages for rebuilding a bi-block in that orientation, using two synchronized gliders not a slow salvo.

People seem to be missing the clean conversion of glider_rider's that gameoflifemaniac pointed out at the top of this page, that started this whole conversation. Yes, once we have an output signal, timing that glider will be trivial. Rebuilding the bait is the painful part, so it's worth investing some time making sure that the bait is really minimal.

Really that's about as good a bait as we can reasonably hope for. Six gliders could reconstitute it -- or five synchronized gliders plus a cleanup, if the catalyst block is taken out (it barely gets in the way of the cheap eater synthesis).

I don't have the tools to figure out quickly what the shortest slow-salvo-ish reconstitution of the bait would be, with gliders all coming from the same side that the output goes to. It's probably long enough to have a worse repeat time than this five-synchronized-glider recipe, even given the various gliders that will have to cross the fireship lane.

The fastest possible repeat time would no doubt involve some kind of horrible multi-stage recovery system. One-time turners and splitters would be arranged to reconstruct the bait as quickly as possible, while at the same time a huge and awkward pile of circuitry is started up, to rebuild the various turners and splitters.

... Ugh. It still won't be either fast or elegant. So at the moment I'm not tempted to try and minimize the repeat time. Maybe minimize the Heisenburp detector bounding box, and not worry about repeat time. How often do you really see a close-packed stream of fireships going by, anyway?
