First of all what is a peristaltic pump ? Well, it is a type of positive displacement pump used for pumping a variety of fluids, they are also commonly known as roller pumps since inside we have rollers that push or suck the liquid inside an elastic tube. Taht's what DIY king YouTube channel presented in his video. He made a homemade version of this devide using some acrylic sheets, PVC tubes, some metal bearings, silicone tube and some screws. To spin the inside rotor he used a geared DC motor so it would have decent torque. He shows us all the process to make this. He also designed a PCB to control the DC motor and change speed and direction using a potentiometer.
