DIY Sonar Scanner Ep. 2 (STEM, RMT tricks)

In this part I reversed the working principle of my DIY sonar scanner the phased arrays are now receivers. I show how that works and what electronics I designed to tackle the challenge. You liked STEM and here is another bit of that for you. Please enjoy and share with a friend!

Give my sponsor Aisler a try: https://aisler.de
They manufacture locally and are still competitive!
