Things I've worked on
Can be divided into scripts, forts and designs.
Minecarts
Both scripts and designs.
Repeaters
- 5-tile 4-cart bumper:
| ▲ | ||
| ║ | ||
| ╚ | ═ | ▲ |
Both ramps are impulse ramps and thus need walls.
What to use it for? Well, if you plant four carts on it, you can get some of the most compact repeaters.
Furthermore, the length can be altered depending if you place carts newest to oldest or vice-versa (build order).
For example, 1199 (1200 with swapping 2 carts): 18-4-14-50, or if you will Ginkgo-Featherwood-Custard-Apple-Bloodthorn minecarts for the smallest day-long counter I know of yet. (tested)
For another example, 33600: 18-84-27-(55 to 56). First can be Ginkgo, third coconut palm, second can be covered pear minecart with two pear logs and last orange inside a lime cart.
A three-month example (for smoking sieges) 100799: 5 21 5 (61 to 65), 100800: 39-86-18-145.
With low friction track stop on 2nd tile: 31-134-33-196, 1. and 3. can be done with almond and mangrove. Tested, with build order from newest to oldest it took 100803 steps; with oldest to newest it took 100797 steps.
I suspect this principle can be extended for smaller ones, perhaps possibly only 2-cart counter? Though with this there are both hundreds of possibilities and larger search space thanks to the generous 250000 subtile possibility space for exploring.
- Weight-adjustable two-cart repeaters
Idea is simple: A light cart delivers periodic impacts to heavy cart on a track stop, only moving a bit. Once the heavy cart goes over the tile, it does a small ring over a pressure plate and returns to start.
Simplest example:
| ╔ | ═ | ╗ | ||
| ^ | ▲ | S | ¢ | ▼ |
You'd open the hatch on start, place heavy cart on 'S'top and light cart on hatch. But the pit doesn't have to be just 2 ramps. Two options I'm fond of:
| ╔ | ╗ |
| ▼ | ╝ |
| ¢ |
NS ramps inside, the cart will deliver 4860 hits if the pit is dry or 4460 hits if filled with 2/7 water. Low impacts are useful for precision counting.
Also, since the cart enters from the side, you can lengthen the time between impacts pretty easily without affecting output.
| ═ | ? | ╗ |
| ╔ | ║ | ╗ |
? is either NS or NE ramp, being 299 or 301 step cycles delivering 29300 per hit.
- 1-cart 1200 (1 day) step repeater
| T | r | a | c | k | s | R | a | m | p | s | / | B | u | i | l | d | i | n | g | s | ||
| ▒ | ▒ | ╗ | ╔ | ▒ | ▒ | ▒ | ▒ | ▲ | ▲ | ▒ | ▒ | |||||||||||
| ▒ | ║ | ╝ | ╚ | ║ | ▒ | ▒ | ▲ | ╝ | ╚ | ▲ | ▒ | |||||||||||
| ▒ | ═ | + | + | ═ | ▒ | ▒ | ▲ | + | + | ▲ | ▒ | |||||||||||
| ▒ | ║ | ╗ | ╝ | ╚ | ▒ | ▒ | ▲ | S | ╝ | ▲ | ▒ | |||||||||||
| ▒ | ▒ | ╚ | ═ | ╚ | ▒ | ▒ | ▒ | ╚ | ═ | ▲ | ▒ |
The S is medium track stop. If you use NS track ramp in the SE corner and replace wall it leaned on with a minecart, it will be hit with 32620 westward and 19560 northward on every day. Alternatively, you could place pressure plate on the ╝ east of track stop - cart will pass over it in 1 step, so this will toggle a bridge.
Of course, one could also easily rig 48 or 50-step repeater to 24/25 step counter, and possibly more compactly.
Scripts
Searcher
HTML 5-tile 4 cart exhaustive searcher for above: https://pastebin.com/Yfik6tF2
Outputs values equal and 1 lower (which happens if carts' build order is exactly aligned).
Can only expect accuracy (exact or off-by-one) for inelastic collisions. Since carts, notably the corner cart, can have remaining slow speed, this means using carts whose weight ratio is more than 2.
