Long time / Arduino Projects

So its been a long while since I've posted anything.  Been busy.

But lately I have been hacking on Arduino projects.  Primarily I have revived my 10x8 7-Segment LED matrix display.   When I built this thing way back in 2004, I drove it with a PC parallel port.   Now I have created a Arduino based controller and coded a Conway's Game of Life simulation.

Each 7-segment display has a 74HC595 shift register on the back, soldered directly to the display using 1/8w 300R as jumpers.  Its all one long shift register, whole thing is driven by only three I/O pins.   Its nice, simple because there is no scanning, but is SUCKS juice.  Very low CPU requirements.
