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
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
