Description
Redstone Torch is crafted from one redstone dust on top of one wooden stick — the cheapest power source in the game, requiring only the most accessible materials. When placed against a wall or on top of a block, it emits a signal of strength fifteen and lights up the immediate area, doubling as a faint light source (level seven).
The block has one critical secondary behaviour: inversion. When the block it sits on receives a signal, the torch turns off, removing its own output. This makes it the standard NOT gate of redstone engineering — the foundation of every clock, latch, and toggle in the game. Players often place a single torch at the start of a circuit to control whether downstream components run by default. Note that running a redstone torch hot for too long causes it to burn out temporarily; well-designed clocks always include a one-tick rest cycle to prevent this.
