DIY sonar scanner (practical experiments)

Starlink, Medical Ultrasound, 5G and my DIY sonar scanner have one thing in common: Phased arrays. Phased what..? My practical experiments convey the physics behind the manipulation of waves in a playful manner. The result is a real DIY sonar scanner. Check it out!
