I want to build a dektop size MicroHydro kit for kids. This could be placed in a stream or small beach wave that fills up a small cradle or bucket of water at one end like a teeter totter. Once the bucket is filled it lifts up and the water then sprays a fountain of water for a few minutes. I want the lift action to be triggered by the lateral movement of wave or stream water flow then it resets the cycle again. Attached is some teflon parts but I need help with spring setup and triggers.
