This is a redstone speedometer. To use this, you run/walk/ride from the pressure plate furthest away from the screen to the on e closest to the screen. To use again, flick the "Reset" Button and wait for the "Reset Complete" light to turn on. "BPS" Stands for "Blocks Per Second." If the "Reset Complete" doesn't turn on, don't worry it must have timed out from the last redstone loop clock. (What?!)
