Electronics work is nearly complete for the wrist mounted life tracker. It’s achieved 100% functionality, and honestly much quicker than expected.
It was fast enough that I plan to expand functionality beyond initial goals.. Just not sure exactly WHAT to expand it’s capabilities to yet..
Right now functionality of the device includes:
- Properly connecting to a given WiFi network.
- Pulling down and displaying NTP converted to my local timezone.
- Displaying formatted time to user via OLED display.
- Presenting user with options of food/activities they want to log, able to be jogged/scrolled through with a rotary encoder.
- Ability to upload log entry to webserver. Initiated by pressing the button/stem of the encoder.
- Processing of log entry and transfer to “permenant” cloud storage.
- Operates as intended via 3.7v battery power.
Without expanding functionality, there’s still a good deal of work to get the device ready for actual use. Primarily, I’ve drafted a new version of the 3D printable housing, it’s the same width but twice as long as v0.1, it also features strap cut outs which should allow for simple straps (velcro?) to hold the device in place on your arm.
v0.1 
v0.2
The biggest hold-up for printing at the moment seems to be an exposure setting which is causing surfaces which require supports to become messy and uneven.
I’ll need to run off some print quality tests to see if I can dial in my exposure times and get better dimensional accuracy..
More to come…
