RGB Pixel Clock Part 1

OLYMPUS DIGITAL CAMERA

 

When I first stumbled across the Equinox Clock by Bram Knaapen (http://www.bramknaapen.com/?p=549) I was fascinated by this clock.

Some time later I found some cheap RGB LED pixels on Ebay (50 pixels for 30$ with build in controller WS2811). I ordered one string of 50 LEDs and tested how to control them. Luckily there was already an Arduino library around called FastSPI (http://code.google.com/p/fastspi/). It did not directly support that chip but the protocol for the TM1804 worked perfectly.

Then I was thinking for some time how to mount the LEDs to create a clock like the equinox clock. After thinking about some possibilities and where to get the tools / materials for them I decided to go for some laser cutting service.

The fingers of this design help you to mount the LEDs to have them evenly spaced and pointing in the right direction. It also provides the holes for mounting the Arduino. Here is the design (dxf): clock_base380

and here are some pictures of the cutted design:
