Nicht mehr überraschend, aber immer wieder noch beeindruckend, was man aus Lego alles auch fernab vom kleinen Spaß nebenbei so stecken kann. Hier sieben verschieden Wasserpumpen von Brick Technology.
Building and testing 7 different motorised Lego water pumps. Each electric water pump is placed in a basin. The basins are connected into a circle. Each pump/basin has a water level sensor that adjusts the speed of the pump motor to avoid overflow. Things to consider: Pump type, flow rate, motor speed and pump speed.
