#72 Making the invisible visible: Tools for debugging and re-engineering electronic designs

In this video I show tools to find out, how a unknown electronic device works. I start with a Multimeter, continue with a Digital Storage Oscilloscope (DSO), and end up with a modern Logic Analyzer.
The goal is to build an enhanced electronic load with a nice touch display and data logging. Could have used an Arduino, but decided to use an ESP8266 because I wanted to have a wireless connection on the bench. And maybe, we will be able to replace the display with a web interface?
