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: aisler.de
They manufacture locally and are still competitive!

Scanner code: github.com/bitluni/SonarScannerV2
Browser based simulator: shadertoy.com/view/NttyW8 (janky and only UHD but ship it!)
