  • Whistle Synth Pi

    July 8th, 2021
    music, tech, whistling
    I made my whistle-controlled synthesizer into a stand-alone device:

    Melody example:

    Bass example:

    Playing bass by singing falsetto:

    It consists of:

    • Raspberry Pi 3 computer ($35)
    • Case ($7)
    • USB sound card ($8)
    • Keypad ($10)
    • 3.5mm to 1/4" cable ($4)
    • XLR to 3.5mm cable ($7)

    It also needs a micro SD card, power (2A, USB), and a microphone. I'm using ones I already had, but it doesn't need anything fancy. If you wanted to make a special-purpose device, I think you could get the materials down below $20; there is nothing especially expensive here, and I'm not using most of the features of the Pi.

    The code is open source: github.

    On the Beach

    I really like going in the water and this beach is a great place for building sand castles and boogie boarding. I also like trying to float on top of big waves. I'm not very good at it. I only float on the flat waves.
