Xronos Clock Kit v2.1
Xronos (from greek Χρόνος [kronos] which means Time) Clock is not your average alarm clock. It’s an open source, hackable and customizable device. It has a stylish look, is hand made, and it talks!
Xronos has an internal backup battery that will allow it to keep time if you forget to plug in. All settings are saved to flash memory (EEPROM), so you don’t have to worry about power loss and all your alarm settings and preferences will be there when the power comes back on! Since all audio files are kept on SD card inside, you can even change alarm tones, or replace voice prompts with your own (though only ones that follow Xronos' naming convention).
Xronos has three cool looking durable arcade buttons that give you simple access to all of its features!
