Digital LED signage
« on: March 11, 2016, 07:19:16 PM »
Is anyone an expert on software and hardware to build and control a 4' x 8' LED sign with 7 lines of text?

The middle school where I teach has gotten some very high estimates to convert our existing school sign to digital.  It has power going to it, and that's all!

Ideas?

I looked into digital signs for my church a while back.
It is actually pretty expensive to get an array of LEDs that big. Depending on how good you want the letters to look (80's video game?), you might want about 50 rows of LEDs, and proportionally I guess 100+ columns. That's 5000 bright LEDs to put in place. (And is the sign double sided?) They all have to be addressable of course, so that's a lot of wiring too. Then you need an interface to drive all of them from a computer (or chip, or microcontroller, etc.).
Once all of that is in place, the software wouldn't be too difficult.

You'll also want to build it so it's weather proof. Water always finds a way in.

Probably best to go with the pro's.
