It’s interesting to hack one of your appliances or lighting projects into a whistle controlled intelligent one. The whistled allows you to do so by simply whistling two musical notes. To set it up, you just need to connect your 5.5/2.1mm DC connector on one end and your load on the other.


To grab a sense of how it actually works, check out the presentation video below:




  • ESD protected PCB, covered in transparent heat shrinkable tubing

  • Voltage must be between 4.5 and 18V at the input (barrel connector)

  • Reversed polarity protection

  • Max current of 5A

  • 16 bits PWM output

  • SWD pads for programming

  • Listening range of 15m / 50feet

  • Cortex M4 microcontroller performing 80 FFTs / sec

  • Maximum voltage on the screw terminals is 25 Volts (don't forget the flyback diode!)
