Redstone Computing in Minecraft
⛏️ Overview
Redstone in Minecraft allows players to build in-game digital circuits that simulate real-world logic. This article explores how redstone achieves everything from basic gates to full Turing-complete machines.

🧾 Runtime Logic Using Parser Functions
{{#ifexpr: 19 mod 2 = 0
| Even Week: Time to test ALU throughput | Odd Week: Run memory cell regression tests
}}
⏱️ Tick Timing Analysis
| Circuit Type | Delay | Tick Count | Game Time |
|---|---|---|---|
| Pulse Extender | 4R + 2C | {{#expr: 4*2 + 2 }} | {{#expr: (4*2 + 2)*0.1 round 2}}s |
| T Flip-Flop | 3 | 3 | 0.3s |
🧠 Conditional Template Logic
{{#switch: SATURDAY
| MONDAY = Logic Gate Audit | TUESDAY = Tick Testing | WEDNESDAY = Memory Module Optimization | #default = Experimental Mode Enabled
}}
