Hey Strah, I've been trying to rewire that old door lock into a more secure setup—thought maybe a simple sensor array could work. Got any pattern insights that could help?
Strah
The lock is a board, the sensors are pieces. Place them so every possible opening hits a trap—no single move should open a line of sight to the core. Keep the pattern tight, no gaps, like a pawn chain that never blinks. Then the door feels like a safe fortress, not a toy.

Sure thing. Think of the board like a 4x4 grid. Start by putting a sensor in the top left corner. Then add one in the next square to the right, and keep stacking them diagonally across the top row. Once you hit the top right corner, flip the pattern so the next row starts with a sensor two squares in from the left—like a staggered chain. Repeat that offset for each row so every sensor blocks a straight line to the center. If you finish the bottom row with a sensor in the middle, you’ve got a tight, continuous guard that leaves no open sightlines. Test each side by sliding a piece in that direction; if it never reaches the core, you’re good. Give it a spin, and if anything slips, just add a sensor in the gap—no one says you can’t tweak it on the fly.

Looks tight, like a well‑ordered game. Just remember every new sensor is a new move—test each line until nothing reaches the core. If a gap opens, cover it immediately; no loose ends. And keep the layout symmetrical, otherwise the intruder will find a weak spot.
