Bump — there are 802 to go now. Is there a suitable block recipe for this partial synthesis? (The substrate is easy enough to be done.)

Tangentially related: [G + notquiteGtoBconduit + beehive -> H + notquiteGtoBconduit] Wow! Has this been run past Bellman yet? I guess a replacement for that beehive is fairly unlikely, since it turns into an R-pentomino that then reacts pretty energetically with the main reaction. It's possible to ...

Oh, so somebody did notice that I made a synthesis for 70P2H1V0.1!

Relevant:

However, there are also conduits that can restart from a glider hitting a beehive directly to make an R-pentomino, with no need for a nearby big bulky Bandersnat (5/6ths of a Bandersnatch, not counting the loaf in its stomach I guess.)

Snatch is fine. Err...I see NSFW connotations with that shorthand if it doesn't have to do with weightlifting or hastily grabbing something. Bander is OK in English, but has a similar problem if this website is translated into French. BS has associations with cow poop, and adding an F before it (fo...

Ideally what seems to be needed is a cheap seed constellation that, when hit by a glider, directly returns a 180-degree glider, or two 180-degree gliders if some still life is present off to the side on the binary tape. Does the constant-return glider even need to emerge in the same reaction as the...

This data storage and retrieval question has come up many times before. Are there better existing solutions for extending a data tape into empty space, that I've managed to forget all about? Or would anyone be interested in coming up with something new that improves on this 75-glider total cost? Th...

EDIT: Here's a design I came up with for zooms up to 2^7, with the added bonus of hexadecimal output... Okay, here's my current printer-builder script. For the moment, the character bitmaps loaded into the printer are hard-coded at the top of the script, in LifeHistory format, following the pattern...

If anyone would like to dig up or invent a less amateur-looking font for a digitprinter, please post it here. Can be fixed-width or proportional, doesn't matter, and it doesn't have to be 15x19 -- any size in that general vicinity would be fine. The main thing is that when the pixels are printed di...

Sweeeeeeeeeet. There's a section in that synthesis where the block's conversion into the two carrier heads is skipped, but the swap-in using the double worm is a matter of copy-and-paste--which I've given to the nonmagical box along with the rest of the synthesis. Now to see if it works! No, it's a...

For completeness, I decided to check out the various non-trivial (but boring) interactions between the new P16 and some other small period oscillators. There appear to be three ways of sparking it with a figure 8. The last two could easily be synthesized by standard techniques, but the first needs ...
