Synapse

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.20.5–1.20.6Newest
Minecraft 1.20.2–1.20.4

⬇ Download for 1.20.5–1.20.6 ⬇ Download for 1.20.2–1.20.4

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Synapse Logo

Synapse

Synapse is a Fabric mod that aims to improve existing redstone components/mechanics, and to add new components/mechanics in a way that does not majorly diverge from the vanilla redstone experience. You may think of it as something of an "overhaul" mod for vanilla redstone.

Current Features

"Calibrated" torches and redstone blocks that output a specific constant signal strength
More sensible music disc signal strength values
Jukeboxes can be silenced and subsequently do not lock hoppers under th em when discs are inserted
Hoppers that face up and transfer items every tick (8x faster than vanilla)

Planned Features

Definite Features

Dispensers fill and empty cauldrons with buckets
Powered detector rail hybrid so minecarts can be read and sent from the same rail
Minecart gate that can be toggled with redstone
Improved item transportation (splitting, filtering, maybe even-distribution)

Tentative Features

Some component or block that stores an input signal strength when powered (locked comparators?)
Auto block breaker
Dispensers can pick up shulker boxes
Ender chests that can be configured to a particular player in order to work with hoppers and other storage tech
