So, some findings from the first prototype test!

1.  The Waveshare Li-ion Battery HAT only provides enough power for about 1hr! As expected really. So I'm thinking the easiest is just to use a powerbank, if I can find a small form factor one. Else, I guess something like Pi Sugar
2. 32GB SD card is way too small! I'll got to a 256GB, since we want to storing at least 8hrs of photos and videos
3. The naturesbytes case is fine for testing, but I need to start designing a custom one as soon as I've settled on components

What's next to-do?

1. Change out the Waveshare Li-io battery HAT for a powerbank, so finding a small one that fits into the case
2. Add the classifier model (already tested on a Pi4) and annotate the images with the top detected species
3. Start collecting images to continue training the model for species
4. Start collecting images to train a new model for individual birds (I think might need to up the the camera resolution to do this  really)
5. 4G/5G dongle - that's not fitting in this case, but good to have the dimensions ready for building a new case
