Redstone Timer
by ThBTT
Redstone Timer adds a configurable timer block that holds a redstone signal for a set delay before passing it on.
What it does
A Redstone Timer receives a redstone signal on its input side, waits for the configured Delay, then sends a redstone signal out of its output side. Once switched on, the output is held for the configured Time, and the block is set through its GUI. Because the delay and the duration can each be tuned, one block can produce a timed pulse, hold a lamp on for a while, or open and close a door after a pause.
The block is built for timer-based redstone control in builds that rely on timing, such as automatic doors, farms, traps and other contraptions. Its output is strong redstone power, so it can drive an adjacent block directly, the way a redstone block does. A Redstone Timer can also trigger another Redstone Timer placed at its input, which chains delays together.
The mod is a Fabric mod for 1.21.1 and runs on the client and server, so both the server and every player need it. It is released under the MIT License and is open source; the source code and issue tracker are public. The first build was published on 2026-05-09, and the latest Fabric file, 1.0.2, followed on 2026-05-10.
Key features
Configurable delay and duration
The Delay before the output turns on and the Time the output stays active are both set per block.
GUI configuration
Settings are changed through a graphical screen on the block, so no commands or config files are needed.
Strong redstone output
The output side emits strong power and can directly power an adjacent block, such as a lamp or piston.
Directional input and output
Each block has a defined input side and output side, which makes it simple to place in a line of redstone.

Use cases
Who it’s for: Players building automated redstone contraptions in survival or creative worlds, and server owners whose players build timing-based machines on Fabric 1.21.1.
How it compares
Redio Signals is open source under the GNU General Public License v3.0 only, runs on client and server, and has a Fabric file for 1.21.4, so it targets a different version than Redstone Timer. Redstone Logic Gates is not open source, uses the ISC License, runs on client and server and covers 1.21.5 – 26.3, adding logic gates rather than timers. TimerDisplay Mod is client-side only under the MIT License for 1.21.1 – 1.21.11 and shows timer values instead of delaying a signal.
