Open lev is an open source acoustic levitating device. It operates by an analog oscillator that produces a square wave of 40khz. Which is then amplified by a full bridge rectifier.
Open lev is Similar to Arduino/Atmega based Acoustic Levitation Build with the exception that there is no programming required. Instead it can be tuned for maximum efficiency with a trimmer potentiometer. This allows for adjustment at different altitudes (sound travels faster or slower). Since the speakers are fixed the tuning allows for a standing wave to be optimize
The Circuit is completely analog and requires no programing
Open lev aims to provide an SMD an THRU kit hole versions for individuals that want to experience the standing wave Phenomenon Up close.
