ProCiv sleeping mask has no amplifier and 180mAh battery. It's not enough. This is 10X louder and will last for 48 hours when used with a 2500mAh battery.

This is only a schematic, no module available as it's for a personal project and uses the existing ProCiv module plus Adafruit modules.

  1. Component List:
    • Adafruit 2000mAh Li-ion battery
    • Adafruit 259 Charger
    • Adafruit TS2012 Amplifier
    • Adafruit 40mm 3W 4Ohm speakers
    • ProCiv bluetooth sleeping mask & module

Here is a video of the completed upgrade:
