Christmas Clock

Anti color-blind clock

I modified this random red/green LED scrolling sign to use a SparkCore as a brain. It now tells the time in UTC and .beats.

Eight Red in a Sea of Green

Since it is red and green, I call it the Christmas Clock. The alternate title is the anti-color-blind clock since I have the background turn on full bright. If you don't like it, you can build your own with the source code from github.

SparkCore LED sign CPU

Like most of these displays it is a row-selected shift register. In this case there are separate red and green shift inputs, with a common clock and latch.

Old LED CPU board

The original board was massively overpowered with an Altera FPGA for some reason.
