Hey, this is pretty cool! Here's inventor Bram Knaapen's
Arduino-powered Equinox Clock, which ditches the traditional
hands interface in favor of customizable LED displays. Inside, a
video that demonstrates the Equinox Clock's main features, and
an overview of its specs.  Here's the demo video:  And, courtesy
Knaapen's web site, here are some specs:  For people interested
in how the Equinox clock was made a short description:  The most
important parts: Arduino Mini Pro USB-Serial converter 12x
TLC5940PWP (SMD) Led drivers DS1307 + battery to keep track of
time Loads of circuitboards (12 black ones and 60 white ones)
The clock works like this: In the bottom of the clock (behind
the infinity symbol) is an arduino mini Pro. The Arduino is
connected to the first of a total of 12 black circuitboards.
These black circuitboards all have a TLC5940PWP led driver. By
using Molex picoflex cables and connectors I daisy-chained 12 of
these led drivers. Every black circuitboard has 5 connectors for
the white LED circuitbo
