Re: Spaceship Discussion Thread

There is an easy modification of the diagonal c/4 advancer spaceship to change the period a bit. The backward-to-ship converter can be shifted forwards by 128 cells, which increases the period by 256 generations. This can be repeated for a few times as long as there is room. Some of the new periods ...

I finished one of the wick trimming reactions for the diagonal c/4 technology. #C A reaction which trims off the end of a useful wick. #C This uses two gliders to sever the wick and a third glider to force #C the burning of the lower section of the wick to the desired mode. #C There are two blocks r...

Re: Spaceship Discussion Thread

I looked for good ignitions for the diagonal c/4 fuse when hit by the evolving debris from the usual sparker fed by a single glider. I don't know how exhaustive this list is, it was generated manually. There were quite a few of them, actually. These reactions only occur at the end of the wick, and s...

Re: Spaceship Discussion Thread

I found two new perturbations that remove debris from the diagonal c/4 glider advancer convoy. One of them is a small spaceship that suppresses the blockade when the fuse is ignited. The second one is the smallest spaceship which suppresses the blinker produced when the advancer emits its glider. #C...

Re: Spaceship Discussion Thread

Here is the third glider advancer for diagonal c/4 technology to send a signal forwards towards the front of the convoy.

Re: Spaceship Discussion Thread

I found a third wick burning termination reaction for the diagonal c/4 wickstretcher.

I improved the fuse-building synthesis used for my diagonal c/4 period multiplying convoy so that the fuse units can be repeated with the minimum possible separation, and which also removes one of the input gliders.

I went back to an old idea that I had dismissed before as being too hard, and it turns out that it wasn't hard at all and even makes things very simple.
