I'm impressed with this project! I built something similar a couple of years ago but it wasn't as polished. This is a prime example of a well-executed open-source hardware (OSHW) project.

I also noticed, like others here, that the tracker's size is a problem. My cat managed to remove the collar with my smaller tracker in just two minutes. I've been considering designing an even more compact tracker, integrating it into the collar itself. It would include a battery, GPS, LoRa with an antenna, and a microcontroller with power management. I'd use a small Heltec LoRa+Bluetooth transceiver for this.

Your work has inspired me to revisit my old project. Thanks!

I made something similar for my dog. Arduino Nano, GPS module, LoRa module, 18650 battery, and an antenna. I then had a "base station" using ESP8266 with a LoRa module and antenna that would forward the GPS data to the cloud. I was in a heavily wooded area and the LoRa signal would start dropping around 1000ft. I didn't know free SIM data was a possibility via Hologram.io or I probably would've gone that route.

I really don't like the idea of attaching a lithium ion battery to my dog's neck, and I never learned how to design PCB's, so I'd also like to revisit my project with some improvements.
