In this episode of DIY or Buy we will be having a closer look at my broken AC/DC current clamp which can be also called a current probe. The job of such a current clamp is simple, visualizing the current waveform on an oscilloscope. So in this video I will explain how such a current clamp functions and how we can make a DIY alternative in order to find out whether it makes sense to DIY such a tool or whether we should stick to the commercial solution instead. Let's get started!
