Redstone

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.

🔣 Logic Gate Emulation

INPUT A  ●──────┐
                 │
INPUT B  ●──────┼────┐
                 │    │
              [BLOCK][TORCH] ───● OUTPUT (1 when A or B is 0)

🔄 Tabbed Examples

<tabs> <tab name="Truth Table">

 A 

</tab> <tab name="Tick Delay"> Repeaters

Each set to 1–4 ticks (0.1s per tick)

Comparator

Lagless delay, mostly for analog signal smoothing

🧬 Memory Cells

           └───[T]───● Q
           │
RESET ●────┘         ⊕ (Q NOT)

🏗️ ALU Configuration (ASCII Model)

      ┌────[ XOR ]────┐
A ───▶                ├───▶ SUM
      └────[ AND ]────┘
B ───▶                ├───▶ CARRY

🧾 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: SUNDAY

| MONDAY = Logic Gate Audit
| TUESDAY = Tick Testing
| WEDNESDAY = Memory Module Optimization
| #default = Experimental Mode Enabled

}}
