In this episode of DIY or Buy we will have a look at peristaltic pumps and find out whether it makes sense to DIY our own version of it or whether we should just stick with the commercial buy option instead. Along the way we will create a stepper motor driver circuit and a suitable 3D print for our DIY version.
