HOW THE WATERFALL SWING WORKS
Water recirculates through 384 independently controlled solenoid valves at the top of the structure to create a wall of water. This water starts from a collection pool on the ground and is pumped up to a 4" distribution pipe that feeds the solenoids. Rotational encoders mounted on the swing axis gather information about the angle and speed of each swing. That information is sent to a computer that predicts the action of the rider. The computer then creates a hole in the wall of water, allowing the rider to swing through without getting wet.

TECHNICAL SPECIFICATIONS
Solenoids 384 independently controlled one way direct acting, normally closed, 24v .25 amp with a 15ms delay. 1/8" ID outlet. They are Spartan Scientific model 3825-07-A203
Controller The controller circuit boards were custom made by Ian Charnas, each one operating 16 solenoids using a simple BJT transistor, connected via RS-485 running 1 Megabaud.
Encoders for Position Sensing 10-bit absolute position Kubler T8.5850.ZP15.B102
Software one section of software is created to convert a gif into the appropriate command for solenoids the second multi threaded program monitors the swing position and controls the solenoids, written in Ruby by Andrew Witte.

Хватит и одного на одну качель - льет/не льет.
