How to Build an RPM Speedometer with Variable Lighting

Monitoring how fast your vehicle, crane, or elevator is running helps prevent over-speeding and gives cockpits a live visual readout. You can convert rotational speed directly into scaled redstone power and display it with variable lighting.

Converting RPM into Redstone Power

1. Connect the speed-to-redstone converter component from the mod to the rotating line or moving mechanism you want to monitor.

2. Run redstone dust or redstone components out from the converter toward your dashboard or control room.

3. Watch how the output scales as your contraption accelerates: the mechanism adds 1 redstone power level for every 8 RPM of movement speed. At 8 RPM you get signal strength 1, at 64 RPM you get signal strength 8, and reaching maximum redstone strength of 15 takes 120 RPM.

Wiring an Andesite Lamp Indicator

1. Place an Andesite Lamp directly next to your redstone output line or at the end of a comparator/dust wire.

2. Start your machine and adjust its rotation speed.

3. Unlike vanilla redstone lamps that only toggle fully on or fully off, the Andesite Lamp dynamically scales its brightness based on how strong the incoming redstone signal is, giving you an instant visual gauge of your current RPM.
