Adafruit MONOCHRON Clock kit - Open source clock platform, make clocks!

MONOCHRON® offers a versatile clock kit perfect for tech enthusiasts. Outfitted with a 128x64 LCD (KS0108), this clock is highly modifiable. The ATmega328 processor is preloaded with an Arduino bootloader for easy customization, paired with a beeping/blinking alarm and a 10-minute snooze feature.

A robust, laser-cut black acrylic enclosure houses the components securely. Timekeeping is reliable with the battery-backed DS1307 real-time clock, preserving time settings across power outages. Choose between European/US and 12/24-hour date displays, making it globally adaptable.

Built with open-source hardware, every design aspect is yours to modify. Embrace DIY innovations with the substantial mod space and soldering prototyping area. The kit includes all necessary parts, a coin battery, enclosure, and a dual-voltage 9VDC power supply.

Experience retro gaming with the pre-installed Retro Arcade Table Tennis for Two firmware, or explore alternative clock firmwares available on the project page. Basic soldering skills and tools are needed, yet assembly remains accessible, even as a first project, within a few hours.
