I didn’t like the over hang of the last iteration of the hardware layout. I ended up placing the board side opposite the display, with the straps on the side. This was my original vision of it, besides having everything on one side. But that would be too bulky right now.
I made up a color scheme for the UI and added some view flipping. Everything is still done with the physical buttons. I can’t seem to get the touchscreen to work on the Pi Zero W. This may make the usage more simple, though I suspect most people would assume its a touch screen.
Hardware wise I want to get an IMU onboard, and consolidate the power boards to reduce space. After that I will focus on designing a 3D printed enclosure and fabric straps other than the scraps I’m using here from old backpacks.
I managed to get the Bluetooth connection reestablished, so the commands and data transfers are back. I also added a notification listener to the android app, which sends that information to the display as well. I picked up that piece from tutorial I found.
I’m starting to learn a lesson with this project. If I don’t design an end goal, this will go on, and on, and on. With more and more changes to my whim. I have a good idea, for the hardware, where it would be complete. It’s within reach.
Here is the GitHub link to the code for the wrist device. I will make another post about the companion smartphone app soon.
