My hobby right now is making a completely local fitness watch without any screen or distractions. Just logs heart rate, spo2, activity, and sleep using actual Bluetooth standard profiles (HRP, POP, PAMP, etc... Instead of proprietary hacked together custom profiles of most watches). No GPS either because if I want that, I will just bring my phone. Maybe an extension of my job though since I design medical device electronics for work. The only feedback is an LED and good LRA haptics (hopefully). I hope to make it compatible either with whoop replacement straps or standard watch bands.
Bit of a serial hobbyist:
That watch sounds like an interesting project. Have you heard of the HealthyPi Move? It's a open hardware watch with a bunch of biometrics, so maybe there's something in the design or code you could use.
Interesting. I had no idea about this project!
Sadly they are using the Maxim sensor hub with seperate LEDs and data acquisition where i am just using an all-in-one sensor.
Who knows? I am making the development board right now so maybe I will find that using the same part will make it easier lol
Very cool project! I wonder when it is called the "pi" when there is nothing related to Pi or the raspberry/orange/banana pi ecosystem? 😂
They had other non-watch monitors first based on raspberry pi. I think they just kept the name for branding.
not all hero's wear caps
That’s super cool!
