Notes on Copper Bulb in Logical Redstone

Introduction

• Discussion around Copper Bulb in Minecraft.
• Perspective focuses on logical Redstone, not typical Redstone uses (like farms, doors, machines).
• Objective: Review the Copper Bulb and its utility in logical Redstone.

Overview of Copper Bulb

• Toggling Feature:
  • Turns on/off with power toggle.
  • Outputs states to comparators (1 when on, 0 when off).
• Changes in mechanics:
  • Initially toggled in one game tick, now toggles instantly.
  • While this is faster, it doesn’t significantly impact its usefulness in logical Redstone.

Applications of Copper Bulb

T Flip Flop

• Functions as a one-block T flip flop.
  • Efficient for logical Redstone circuits like games or computers.
  • Smaller and faster than previous designs.

User Interfaces

• Used for toggles in settings of Redstone games.
• Comparison between Copper Bulbs and Redstone Lamps:
  • Both designs can control settings.
  • Preference for levers over buttons due to clarity of function (on vs off).

Button Selector Panels

• Alternate designs with Copper Bulbs.
  • Smaller and effective for toggling selections.
• Personal preference for traditional designs due to clarity and familiarity.

2D Screens

• Allows users to draw pictures with a grid of Copper Bulbs.
  • Novelty of one-by-one input and instant feedback.
• Issues with data utility and spacing considerations.
  • Preference for using larger input/output designs for easier data manipulation.

Memory Applications

Read Only Memory (ROM)

• Copper bulb does not improve ROM implementation.
• Alternatives like redstone blocks or barrels provide better solutions.

Read Write Memory

• Difficult to implement Copper Bulbs for read/write memory.
  • Requires XOR gate to write efficiently, complicating design.
• Existing designs with repeaters preferred due to simplicity and effectiveness.

Counter Applications

• Binary counter utilizes T flip flops; Copper bulb design doesn't improve synchronization.
  • Preference for synchronized designs with repeaters to avoid unsynchronized counting.

Screens and Display Options

• Copper bulbs allow flat screens but are challenging to reset effectively.
• Difficulty in creating movable displays without complex circuitry.
• Traditional methods (lamps) preferred for dynamic displays in games.

RGB Screens

• Copper Bulbs are color limited (on/off only) which reduces their practicality for RGB displays.
• Suggested alternatives:
  • Concrete traps for color variations.
  • Maps for color choices in displays.
  • Using texture packs for varied color displays.

Conclusion

• Copper bulbs are a solid addition to Minecraft, igniting creativity.
• Personal stance: While they are great for some uses, preference remains for traditional designs in logical Redstone.
