Vortex Watch

Description

This watch is a collaboration between myself and Jamal Davis. Our goal was to create a wearable-sized version of the infinity mirror clock projects we had seen around web. It uses its RGB LEDs to indicate time by assigning hours, minutes, and seconds to Red, Green, and Blue lights respectively and overlapping these hues to create primary, secondary, and tertiary colors that represent the time.

Some features:

A 3D printed titanium and resin case
Laser cut/engraved mirrored acrylic face
Battery charging circuit
Fuel gauge to keep track of battery charge level
Two capacitive touch contacts on the side to act as the watch's interface and
A DS3231 real-time clock (RTC) for accurate time-keeping
Different programmable face styles
Set-time, battery charge level display, low-power sleep, and game modes

V6.1 In Progress
nolandoktor • 11/12/2022 at 07:03 • 0 comments

Found/fixed a few mistakes in V6.0 (Bringup log in Git has more details here). Had some trouble with fake fuel gauge ICs from an Ebay/Amazon sellers *big surprise* (picture down bellow showing an OEM chip on the right vs fake on the board). Amazon seller sent 5 ICs each different from the next.
Decided to switch new fuel gauge ICs (MAX17048) that could be sourced from a reputable seller so fingers crossed this version works. V6.1 was designed to use the same ATSAMD21G18 MCU as V6.0 but this will be my last 3 of these ICs.
A V6.2 is in the works and will be the next and hopefully last design which will use the smaller sibling to the ATSAMD21G18, the ATSAMD21E18 of which I was able to source an additional 10 ICs.
V6 is Assembled - More testing is required

V6

V6 is in the works after acquiring some Unobtanium MCUs to test with. Qi was dropped due to constraints with board space and chip supply. Stay tuned!
