Hey George thanks for you'r responce, The purpose of this huge MTC display is for real-time musical analysis. it is to be shown in front of an audience of 150 people. In other words, instead of shouting to the audience "we are in the middle of the second movement of the symphony.." they can see the time on the clock that corresponds to the printed analysis they have in their hand. Up to now I've been using a custom made display hooked up to a home C.D ROM display that just copies the L.C.D display to larger dimensions. But I want to move into the 21st century and hook a laptop's output (from a sequencer) that plays an MP3 strip to a display that shows the time on one hand and on the other plays the audio throw the audio output to the P,A system. So much for the "why I need this" , as for the diminutions it’s a total size of the current box I have now the led rings are smaller 12X6 each digit. And I only use the two middle pares Mm:Ss I don’t need the hours or frames. Can you think of anyone that can help me or point me in the right direction???? Or can you think of anyone that can custom build this for me? Why is it such a big project? HELLLLLLLLLP!!! Tanks Jason
