Copper Buttons - New Redstone Buttons
by marcsanz-dev
Copper Buttons adds a set of redstone buttons made of copper, and each button changes its signal length as it oxidizes over time.
What it does
Copper buttons weather through four stages, from clean to exposed, weathered and oxidized, the same way regular copper blocks do. A more oxidized button keeps its redstone pulse on for longer, so a fully aged button works as a compact signal extender. Players who need a long delay for a piston door or a hidden trap can pick the stage that matches the timing they want.
A craft with a single copper nugget makes a base button, and a button can be waxed with Honeycomb to freeze its oxidation stage permanently. Right-clicking a waxed button with an axe scrapes off one oxidation layer and returns it to the previous state. A direct lightning strike cleans an oxidized button back to its pristine form, and the strike also sends sparks that partially clean nearby copper buttons.
The mod requires Cloth Config API and Fabric API, and the optional Mod Menu can be added to open its configuration screen. Copper Buttons runs on client and server, so the server and every player need it. Files are published for Fabric only, for 1.21.11, and the mod is released under the MIT License, though it is not open source.
Key features
Copper button crafting
New copper buttons can be crafted, and their timing is adjustable so each one suits a specific redstone build.
Oxidation-based signal length
Each oxidation stage lengthens the redstone pulse, so buttons act as signal extenders without extra components.
Waxing with Honeycomb
Combining a copper button with Honeycomb locks its oxidation stage in place for good.
Scraping with an axe
Right-clicking an oxidized waxed button with an axe removes one oxidation layer and restores the previous state.
Lightning cleaning
A lightning strike returns an oxidized button to its clean state and partly cleans other copper buttons nearby.

How it compares
AutoOxidize is client-side only and open source under the MIT License, covering 1.21 – 1.21.5, so it does not change the server and is not a redstone mod for servers. Keyboard Place Extender is a client and server mod for 1.21.5 – 1.21.11 under All rights reserved and is not open source, so it adds placement features rather than buttons. Regius Redstone is also client and server for 1.21.11 under All rights reserved and is not open source, so it differs from Copper Buttons in licensing and function.
