Every 2 years my local school system had an auction. This time, I picked up a large LED sign for $22.50.
The sign had a power cable, a couple of ports, and a label that read "Data Design Corp." I bought the unit assuming that I wouldn't be able to get any datasheets or manuals for it, but I did some searchign anyway. I ended up talking to a former VP of the company, who told me the company had been sold and dismanteld years ago.
At this point I had 2 options. The first was to try to figure out the connections on the controller board, and reverse engineer some kind of interface.The second option was to ditch the controller board all together and build one from scratch.
