About this Mod

Redstone Pen

A Minecraft (Java Edition) mod adding a pen to draw
Redstone tracks more accurately. Inspired by the Redstone Paste mod.

Description

Adds "one pen to draw them all" - and helps with simpler Redstone handling.

Redstone Quill and Pen Items

Craft and use them to draw or remove thin Redstone Tracks. Multiple independent tracks through one block
space are possible. There are two versions:

  • The Redstone Quill uses Redstone dust directly from your inventory.

  • The Redstone Pen stores Redstone in the item, and can be refilled in the crafting grid with Redstone
    Dust or Redstone Blocks.

  • Both allow to inspect the current signal of a block, track, wire, or device by sneaking while you hold
    the pen/quill and look at the block of interest.

  • Both do not destroy blocks when left-clicking, except blocks with no hardness (like grass, repeaters,
    or comparators).

Block Signal Connectors

Especially for compact wiring it is desirable to decide weather a Track shall power the block underneath
or not. Therefore the Pen-Tracks do normally NOT connect to the block they are drawn on. To change this,
simply add an explicit connector by clicking the centre of a Track with a Pen (see the round blob in the
image). Tracks do intentionally not pass indirect power (through blocks) to other Tracks, so you can power
said blocks from independent routes without interferences:

Redstone Relays

Relays are like redstone powered "solenoids" that move builtin Redstone Torches back or forth, so that they
re-power ("re-lay") Redstone signals to 15. They can be placed on solid faces in all directions. Output is
only to the front, inputs are at all sides except from above. The internal mechanics ("relay types") define
what happens at the output side when the input signals change (relay, invert, flip etc). Relays also detect
indirect power from blocks they are placed on, and can therfore be used to pass Track signals through
blocks.

  • Redstone Relay: Straight forward Input-On-Output-On relay. Different from a Repeater it has no
    switch-on delay, but instead a switch-off delay of one tick (redstone-tick=100ms).

  • Inverted Redstone Relay: Input-On-Output-Off relay. Switch-on delay 1 tick, no off delay.

  • Bi-Stable Redstone Relay: Flips when detecting a off-to-on transition at the input ("rising edge";
    input off->on --> output changes).

  • Pulse Redstone Relay: Emits a short pulse at the output side when detecting a off-to-on transition
    at the input ("rising edge").

  • Bridging Relay: A Redstone Relay allowing to cross tracks. It forwards power back to front like a
    normal Relay, and has an additional independent wire left-to-right.

Redstone Logic Control

Simplified PLC-like, text code based signal controller. Details
are in a in the documentation here

Frequently Asked Questions

Redstone Pen server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is Redstone Pen compatible with fabric and forge and neoforge?

Redstone Pen officially supports fabric, forge, neoforge for Minecraft 1.21.1, 1.21, 1.20.6. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Redstone Pen – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Redstone Pen consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
