A little birdie told me this is what's inside:
A Nordic nRF BLE module
A TI class-D audio amplifier. This drives the "output coil". It's not even wired up correctly -- there's a DC offset issue caused by not following recommendations in the datasheet.
A little tamper detect switch! Easily bypassed, though.
A TI BGA lighting controller for the LEDs.
This is what it does:
Plays back "songs" stored as... triple-encrypted WAV files.
Interferes with your (analog) headphones, if you wear it just right
Has a light!
Transfers money away from stupid people
It's complete woo-woo.
And it's design is based on a previous product that is supposed to fight cancer
