Polyphone .
It's a project that started during course work in university but far too passionate to be restricted by it. Unfortunately not all members of the team were as involved as the software team. Even though this project died a horrible death, it was an awesome experience!
The mission was to create a phone from parts that are not designed to be used in a phone. This restriction moved us away from existing android ready Chinese boards.
Hardware that was used:
- Raspberry PI Zero as a motherboard
- SIM808 as a GSM module
- Digispark as power and buttons controller
- Ready to go screen, battery, charge controllers
The OS for the smartphone was Arch Linux, btw. With its hosted repository for future updates. There already were:
- Custom Window Manager
- Custom Boot Animation (Plymouth)
- Custom Suite of Phone applications (GTK at first, but Qt later)
