Introduction: Easy Acoustic Levitator
Today I will show you how to make an easy acoustic levitator using ultrasonic sound produced by an HC-SR04 rangefinder and an Arduino. It can float small balls of styrofoam. Its a fun and easy project to make with your kid or have a creative gift for a maker in your family.
Step 1: Materials Needed
Step 2: Tools
- Desoldering Pump/Wick
- Soldering iron
- Computer with Arduino IDE
Step 3: Desolder Transducers
Take your desoldering pump, soldering iron and ultrasonic module. Desolder the two transducers. If you need help doing this see step 3 of: The Ultimate Guide to Desoldering
Step 4: Prep Arduino
Step 5: Finishing Up
Power up the Arduino and place the sensors about 1/2-1/4 inch apart.
To place the styrofoam ball use a teabag.
