This is fully assembled clock, no soldering required! It will work out of the box (just set time and date).

Xronos Clock is not your average Alarm clock.

It’s open source, hackable and customizable device. It has a stylish look, hand made, and it Talks! Heck it will even tell you temperature inside your room.

Xronos has 3 cool looking durable arcade buttons that give you simple access to many of it’s features such as:

  1. Dual Alarms: Alarms have both simple Daily or Weekday setting as well as a more customizable selection of days of week when. You can even choose any of 10 Alarm tones be it a buzzer, a melody or special effect such as train, thunder or police siren.
  2. Change display color to Green, RED or Orange.
  3. Adjustable Display brightness -12 or 24 hour mode
  4. Celsius or Fahrenheit selection for temperature sensor
  5. Ambient light sensor automatically adjusts display brightness
  6. Easy access to micro SD card, backup batter and FTDI
  7. Optional Wireless RF module allows clock to receive data from remote sensors (such as outside temperature and humidity)**
  8. Optional IR Receiver with remote

Xronos has internal backup battery that will allow it to keep time if you forgot to plug in … if it’s just for an hour or … for a year or two! All settings are saved to flash memory (EEPROM), so you don’t have to worry about power loss. All your alarm settings and preference will be there when power comes back on!

High efficiency durable US Compatible Power Supply is included*!

Since all audio files are kept on microSD card inside, you can even change alarm tones, or replace voice prompts with your own .

I make Xronos clock by hand, meaning soldering, assembly of the laser cut acrylic enclosure, paint filling, etc. Thus quantity is limited.

There are currently two varieties, one with yellow middle button and one with orange. Please choose which one you like during checkout!
