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
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
