My intention is to turn my Samsung Gear S3 Frontier Smartwatch into a Smartbracer. In the process, replacing the 380 mAh battery that sits within the watch's housing, to a 3000+ mAh battery that resides in a pouch in the bracer.
I have a couple older Smartwatches (Pebble, and Pebble Steel) I will use as guinea pigs for this project. I have already ordered 3.7v 3000mAh battery to test with the Pebbles, and a 3.85v 3000mAh battery for the Gear S3 if my idea pans out. I will prioritize the hardware portion of the project until I have a working concept. Then I will team up with a leather worker on the Bracer part.
Enjoy this project?
