The second clock kit from ladyada & Adafruit Industries, we present MONOCHRON!
We wanted to make a clock that was ultra-hackable, from adding a separate battery-backed RTC to designing the enclosure so you could program the clock once its assembled.
128×64 LCD (KS0108) – we special-ordered the black and white display
ATmega328 processor (we even stuck an ‘arduino’ stk500 bootloader on there too)
Laser cut enclosure in black acrylic
Beeping/blinking alarm with 10 minute snooze
Battery backed-up real time clock (DS1307) keeps time even when power is lost for years
European/US 12 or 24 hour time display as well as date
Completely open source hardware, all firmware, layout and CAD files are yours to mess with
Plenty of space for mods, a prototyping area for soldering stuff in
