DIY Pocket binary Alarm Clock

Binary Alarm Clock provides an original and innovative method of displaying the accurate time. Instructables member linux-dude shared his compact binary alarm clock that uses an Arduino Duemilanove (which fits perfectly in the tin) to keep time and control the indicator LEDs. The LEDs are arranged in two rows as you would expect, representing hours and minutes. A small piezo speaker serves as the alarm buzzer, which should be sufficient to wake up most people, though something bigger might be required for heavy sleepers.

So what’s you waiting for???? Grab the ideas and go on to try it for yourself – your own binary alarm clock that fits in your pocket!!!!
