A clock that relies on failure for accuracy

 And now for something completely different - Michael Le Blanc has taken a different approach to creating what is his "Average Clock". Based on the premise that timing crystals and inexpensive real-time clock ICs will equally either lose or gain time over a long period of use - his system then uses a host clock which determines the time by calculating the average from six other clocks. Communication between the clocks and the host is via the I2C bus - and uses simple 4051 CMOS ICs to switch I2C bus (and thus each clock) on the fly. A clever solution in itself.

Furthemore Michael has provided the details and notes to reproduce the system yourself, so visit his interesting site to get started. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

If you're prototyping Arduino projects on solderless breadboards, blown the MCU on your board, or making your own such as the clock installation mentioned above - save time and hassle with our new ATmega328 microcontroller pre-loaded with the Arduino Uno bootloader:

It's the same one as found on our ElevenKitTen and the original Arduino Uno, plus it has a very useful pinout sticker attached to save confusion when wiring it up. So for more information and to order, click here. And we also sell the stickers!
