Bedrock breaker: removes 4 bedrock blocks side by side
4 bedrock · 27 blocks
Removes 4 bedrock blocks side by side in the Nether roof's top layer, from on top of the roof. The machine arms the piston standing on each bedrock once every 6 ticks (0.3 s); one key press at that moment (Attack and Use bound to the same key, the piston breaks and a piston facing down goes in its place) and the bedrock under it disappears. A press at the wrong moment is undone with one more press. You need an Efficiency V pickaxe and Haste II from a full beacon, so that the piston breaks instantly.
fits in 5×3×5
Every size 7
The best design for each size: pick one to see it.
Try it
Press play, then press Press under the view (or the p key), or tap the piston standing on the bedrock: it breaks and a piston facing down goes in its place, as the key bound to Attack and Use does in the game. In an armed tick (one in every 6) the bedrock under it disappears; any other tick it stays and the piston is left facing down: tap it again to put it back. To hit the armed tick, pause and step one game tick at a time: it comes right after the piston's arm finishes extending.
How this design does it: Four bedrock side by side: the end pistons face out, the middle ones face up, one stone and observer each; the clock line continues on blocks behind the observers (6 blocks per extra bedrock).

In depth
arms a piston standing on the bedrock every 6 game ticks; one key press (Attack and Use on the same key) at that moment swaps it for a piston facing down, and the bedrock under it disappears
How to try it
Measurements
| metric | value | what it means |
|---|---|---|
| armed | every 0.3 s | the longest wait, in game ticks, between two moments where a press removes the bedrock: a press at a random moment works once in that many |
| bedrock | 4 | how many bedrock blocks side by side one build removes |
| miss | one press puts the piston back | what a press at the wrong moment costs |
Notes from its designer
Four bedrock side by side: the end pistons face out, the middle ones face up, one stone and observer each; the clock line continues on blocks behind the observers (6 blocks per extra bedrock).
