It's been quite a while since I stopped working on the Person Locator Project in December 2022, so my first task is to review how much I had actually accomplished at the point that I had stopped.
This is the cover image that I had for my project draft:
And my original proposal:
"I am going to build a cellular based person recognition device with geolocation. I will use a Nicla Vision board with the ML model developed using Edge Impulse. The Nicla Vision will interface with a Swan Feather board and send notifications and location via the Cellular Notecard."
Looking at the existing hardware I can see that I had already made changes to the original hardware implementation plan. The Swan Feather board wasn't really required since the Nicla Vision board can directly interface to the Cellular Notecard and that allowed me to use a simpler carrier card and reduce size and power. I also noticed that I had started to add a momentary pushbutton and three 3mm LEDs. These parts had not been wired yet so I'm not exactly sure what I was intending - I guess the pushbutton for facial recognition image capture and the LEDs for status.
Here is the 3D printed case - the LEDs are not installed:
And the boards mounted on female headers on a protoboard. The NoteCard is mounted on a NoteCarrier-B (no longer available) and the Nicla Vision is above. The dual antenna is for cellular and GPS.
The protoboard wiring - currently just the I2C communication interface and power/GND connections:
The bottom of the case has some mounting holes for adapter mounts and some clips on the sides to retain the protoboard:
A closeup of the Nicla Vision showing male headers that I added for test points and the last 2 on the right jumper the power together when running on battery - I need to add header pins for the LEDs and pushbutton:
And finally a side view under the NoteCarrier where there is space for a LiPo battery -the battery connector is on top to the left:
Next I'll need to review the state of the existing hardware - I hadn't really gotten beyond initial testing - so this is where most of the effort will be to finish this project.
