I'm building a hackpad, WOOO.
DaOS is a built from scratch kernel. Originally built for Hackclub Boot, it continues its legacy here.
This is my NZQA scholarship technology project. It is a small device which can fit in your pocket or bag, and will track your tramping, hiking, walking, running, cycling, skiing, etc. It uses a Ublox max-m10s gpu module on a fully custom pcb, with an esp32-c6, battery management system, power management system, serial connection and 2 usb ports for 2 different reasons (one is charging the other is flashing firmware which can also be done from testpoints in case there is too much signal interference). It has a web ui, which you can use with an account to look at your past trips/exercises it can connect to your phone with bluetooth to set if you're starting a tramp or stopping a tramp and also upload to the server and look at your past trips/exercises as well.
