Clocks have taken many forms of the years, starting with shadow clocks and sundials in Egypt around 3500 BC. Obviously, these could only tell the time while the sun was out. Water Clocks followed which could track time in the dark. Water Clocks are basically a bowl with a hole in the bottom. This bowl was set in a container filled with water. The water entered the bowl at a consistent rate and graduations on the inside of the bowl showed how much time had passed.
Mechanical clocks followed, as did quartz and the atomic clock. We have now entered a new era in time-telling, the Bamboo LED Clock. [Pascal] brings us this funky fresh chronometer all the way from Germany.
The front face is made from a bamboo pizza plate and gives the clock some modern minimalist pizzazz. A 1-meter long LED strip is attached to the circumference of the plate and contains 60 individually assignable RGB LED’s. An Arduino and Real Time Clock are responsible for the time keeping and coordination of the LED’s.
As you can see in the photo, 2 of the LED’s colors are used. The single red LED indicates the hour. The strip of blue LED’s show the minutes. If you’d like to build one of these [Pascal] has shared the Arduino code on his Instructables page.
That’s pretty cool, though I’d have only one LED lit blue for the minute, instead of all the prior ones as well. And you could have green for seconds.
This begs to be either a round shield or have some sort of logo on it…
Nothing says esthetic sensibility better than a circuit board nailed to your wall.

Gahh! I have the Gcode ready to mill mine out of bamboo worktop! Why do people keep beating me to it!
The design is like the BlinkenClock:

Is it just me or is this simply an atmega+DS1307 (or, better yet, DS3231) clock? I’m not sure what’s the hack. Actually I’m not sure why is this any different from any other digital clock.
