Mr. Hotdog Posted January 12, 2007 Report Share Posted January 12, 2007 I would Like to build a large red LED sign using ultra-bright red LEDs that have a wide viewing angle. I'm looking at 12” high letters, up to 12 characters, power supply and PLC to constructed unit.Schmatics and a parts supplier would be most helpful.

Herman the German Posted April 12, 2007 Report Share Posted April 12, 2007 ??? Did I get that right? The symbols are supposed to be one foot high? If so, I'll think about a schematic. Second question: Just numeric display or alphanumeric? Quote Link to comment Share on other sites More sharing options...
