DIY sonar scanner (practical experiments)

A DIY sonar scanner project using phased array technology with 8 ultrasonic transducers to create directional beams. The project demonstrates beam forming principles used in modern technologies like Starlink antennas and medical ultrasound. The implementation uses an ESP32 microcontroller to control phase shifts between transducers, creating a scanning sonar capable of 60-degree field coverage with improved directional accuracy compared to single transducer systems.
