Electronics enthusiasts or those looking to learn
more about electronics may be interested in a DIY world clock which has been
created using a little Arduino programming, Arduino development board and a
handful of LED lights all enclosed in a custom-made wooden frame.
The DIY world clock can display time by spelling it
out as you expect, or can use the letters as a matrix in order to show the time
in digital format. The LEDs on the world clock face can also be configured to
form an “analog” clock if you prefer and the system can also reveal
temperatures and humidity as well as play simple games such as Game of Life,
Simon and Tetris.
In stand alone mode the clock runs off it’s built in
temperature compensated real time clock with an accuracy of ±2ppm from 0°C to
+40°C When running as a slave off a Master Clock time is synchronised on every
30seconds past the minute. Summer/Winter time is also automatically adjusted by
one of my Pragotron Master Clocks on the BSTin (D7 Nano) pin. A manual switch
can be added instead if quick summer/winter time change is required. There is
an option for PIR control so the clock automatically turns off when no one is
in the room. The Clock measures 500mm x 500mm weighs 12lb (5.5Kg) and is
designed to be wall mounted.

clock jump over to the Brett Oliver website.
