I recently saw the posting
viewtopic.php?f=2&t=515&p=160591&hilit= ... ip#p160591 by PHPBB12345 about a period 60 3c/10 PI-crawling reaction supported by two rows of blocks.
That reaction is really useful. Firstly, it has sparks which extend past the block rows which can perturb objects as it passes by. Secondly, it can be reached from behind by a c/2 spaceship stream. Thirdly, the gaps between components are large enough to allow gliders to pass through.
Here are a few results I found.
Code: Select all
#C A period 60 3c/10 PI-based crawler converts a LWSS to a forward glider.
#C This shows two LWSSs from a stream separated by 12 cells showing
#C that the reaction is repeatable. Similar reactions exist to create
#C backward gliders or other objects.

The two rakes above are much smaller than my previous PI-based rake!
More importantly, the output is trigger-able. The boats are optional, so if there are gaps in the boat rows, then there are gaps in the glider
streams too.
Here is a construction that uses this to create an irregular stream.
Code: Select all
#C A high period growing puffer based on period 60 PI-crawling reactions.
#C This uses a four period 60 PI ships supported by block rows
#C provided by c/2 puffers. Three of the PIs are used as rakes to
#C create a forward LWSS stream. The fourth PI turns LWSSs into
#C gliders to delete some of the boats.

Ideally, the forward gliders should be turned into boats by another PI reaction to form a positive loop, instead of the negative loop I have here. I couldn't find a way to do that since the blocks are too close to the boats.
Also, the cleaner LWSS producing reaction for three gliders should be used instead of the one shown here which produces a bit of junk, but the clean one doesn't work for period 60 rakes.
I am hoping that maybe these irregular streams would help to create a PI ship since information can be encoded by the spacing of the LWSS stream. If a couple of the streams are used to create forward and backward gliders with adjustable timings, then the reactions of those gliders could be used to build almost all of the block and boat tracks that are necessary. The LWSS streams can be made arbitrarily long without adding any new PIs that need supporting, so the recipes could be as slow as needed.
Of course, a 3c/10 helix would still be necessary to support the top PIs of the LWSS streams, but there are only a few of those. The helix itself can be constructed as just described.
PS: I have no idea if this is new, so for the moment I am still posting to this thread.
Edit:
I think my idea is not feasible. I forgot that the front of the reaction is moving, so any output gliders couldn't react with previous ones.
The solution for this might be to create a downward spaceship stream which could do the slow salvos. But it's all too complicated. Sorry.
Edit 2:
For the purist, the rakes seen above might seem to be just fly-by reactions since the boats used in them aren't part of any PI mechanism. (In a possible future complete PI ship that wouldn't matter since the boats WOULD be produced by other PIs.)
Here is a non-flyby rake if you really want to see one.
Code: Select all
#C A period 60 PI-crawling backwards rake.
#C This uses two PI crawlers whose sparks interact to form
#C backward gliders. The PI-crawlers are supported by four
#C tracks of blocks built by four c/2 puffers. Many other outputs
#C can be created by changing the interaction of the sparks.

The disadvantages of this rake are that it uses one more row of objects to support it, and also that its output is fixed at period 60.
