Redstone Diode
Redstone Diode adds one simple block that passes redstone power in a single direction, made from stone, quartz and a redstone torch.
What it does
The block transmits power only upward: a solid, conductive block placed below it lets the signal pass through, and the block receives power from the side it is facing. Crafting it uses a stone block, quartz and a redstone torch placed on top of the recipe grid. Installation needs Fabric on the loader side, and the mod runs on client and server, so both the server and every player need it. Files are published for Fabric only, for 1.21.11, with 1.0.0 as the latest build.
Key features
One-way power block
The block carries redstone power upward from a conductive base, keeping circuits from feeding back into their source.
Simple crafting recipe
The block is made from stone, quartz and a redstone torch, so it can be crafted early in a survival world.
Single-purpose design
The mod adds only this one block, leaving other redstone mechanics and vanilla behavior unchanged.

What the author says
This adds one simple block: the Redstone Diode. What this does is attaches to any solid + conductive block below it, and transmits the power that block recieves upwards. It's as simple as that! The crafting recipe is a stone block, a quartz above that, and then a redstone torch on top.
