I need a set of 4, 6-digit (hh:mm:ss) 12 hr clocks, using 1-2" tall LED segments for the displays. One clock must be a master and the other 3 slaves,s o thay are always synchronized. A wireless connection would be great, but I realize it is unllikely due to cost constarints. All clocks must run on stanard 110 V power. I am looking to be as economical as possible! Commercially availbale clocks are priced in the thousands, I am looking to spend a tenth-or-two of that! Email me at [email protected] if you think you can help me out!
