LED Sign

A few years ago a relative, Ernie I think, gave me a sign that someone was throwing out. It was large and had a car repair place advertisement. Well I removed the guts, got it working, reprogrammed it and put it in my own cabinet. The problem now is that it is too big to fit in the window.

As I was testing it out our cat Bling or as I call him stinky, decided to attack the sign. He normally attacks my laptop computer screen climbing on the keyboard as he does it.

I had to rearrange the guts to make the sign smaller. I moved the logic board to be behind the sign board. The transformer did not fit so I put that on the back side. The brown board has a 555 and a 4017 that resets the sign after 20 seconds so the car advertisement does not come up like it used to.
