Crafting Recipe
1 redstone (center) + 2 redstone torches (left+right) + 3 stone (bottom) = 1 redstone repeater. Functions: 1. Refreshes signals weakened below 15. 2. Adjustable 1-4 tick delay (right-click). 3. One-way signal (input->output only).
Three Functions
A repeater does three things: extends signals (redstone strength drops to 0 after 15 blocks; a repeater resets it to full), adds delay (right-click to set 1-4 ticks), and enforces one-way current.
Circuit Notes
Repeaters are essential for long-distance transmission and timing circuits. Adjusting delay builds clocks and sequenced triggers; the one-way property isolates complex machines from signal feedback.
