Build DIY sonar systems using ultrasonic sensors and measure how sound behaves. Create echolocation experiments inspired by bats and dolphins. Build resonance chambers to visualize standing waves. Experiment with sound speed in different materials. Use cheap sensors and Arduino boards to detect distance using sound echoes. Turn physics of sound into interactive, tangible experiments you can hold and hear.
Jak zacząć
- 1Source a HC-SR04 ultrasonic sensor (cheap online)
- 2Connect to Arduino or Raspberry Pi with basic code
- 3Mount on a servo motor to sweep distances in an arc
- 4Send ultrasonic pulses and measure return time to calculate distance
- 5Map an area using sonar readings and create a 'sound image'
- 6Experiment with different frequencies and materials

Gdzie się uczyć
Plot twisty
Sposoby na urozmaicenie, gdy podstawy się znudzą.
- Replicate echolocation behavior used by bats
- Create a sonar-based room mapping system
- Build a simple theremin using distance sensors
Ciekawostka
Bats emit 10-200 ultrasonic calls per second—your DIY sonar works on the identical principle they've perfected over millions of years of evolution.
