In this episode of DIY or Buy we will be having a closer look at a commercial tachometer (RPM Meter) and test it in order to find out that it is pretty much unusable. Afterwards I will show you how a 3€ IR distance sensor works and how we can use it to build a proper DIY tachometer that functions properly. Let's get started!
