MONOCHRON® is a new clock kit from Adafruit! This easy kit is easily hackable to do whatever you wish, it's a clock platform - have fun!

Comes with: clock kit (includes all parts, programmed chips and LCD), coin battery, enclosure, 9VDC power supply for 220V or 110V

The firmware shipped with the kit is for the Retro Arcade Table Tennis for Two as shown in the video below. Adafruit have other clock firmwares available on the project page if you would like to change the display. This clock no longer includes the FTDI Friend + extras for updating the MONOCHRON with new clocks we suggest picking one up if you want to reprogram the clock (Adafruit's tutorial for how to do this is on the MONOCHRON website.

You'll need some basic soldering & hand tools that are necessary to assemble it! The good news is that this is a pretty basic kit and even if its your first soldering project, it shouldn't take more than 2 or 3 hours to put together

For much more information including parts list, instructions, videos, etc. check out the MONOCHRON website

    Beautifuly packed and it's a lovely bit of gear (Posted on 7/03/2017)

  2. Review by Ben - Educational, functional, nice appearance verified purchaser

    The Monochron's a great little kit. The hardware's easy to put together - my 13 year old with one previous kit under his belt finished all the soldering in a couple of hours, then the next night put it all together and the result looks great.

    The board has a small prototyping area and provides access to all the micro pins, which can be handy: we added a light sensor for automatic brightness control (details are on the Adafruit forum).

    Alas, the software is not beginner-friendly - few comments, kind of hard to follow. Fortunately there's a little clock hacker community at the adafruit forum, check out Emuchron.

    Nitpicks: the supplied power supply is for the US and useless in Australia, so budget another ~$18 for a 9V DC plugpack from Jaycar. Also, one of the buttons failed after a couple of days, fortunately Jaycar carry identical replacements (~$1).
