Vintage Headset Conversion to Bluetooth @QuinnDunki

As @quinndunki writes on blondihacks: Because everything is better with bluetooth.

No, I wasn’t kidding. I wear these every day.

Here’s how the PowerBoost and my additional regulator circuit fit into the battery compartment. You can see that I’m using a 9V battery header wired in reverse to supply power to the Earmark’s original 9V battery hookup. I’m trying to be as non-destructive as possible.

Besides the Adafruit PowerBoost, it uses an Adafruit amplifier. Neat
