Hi all,
I have an opportunity make a little money if I can design a display that
has 5 - 36" tall digits on it. I have always wanted to make one of these
anyway but I wanted to do it with LEDs. Does anyone have any experience
with this type of design. Questions that came to my mind were:
1. What should the width of each segment be? The height will be 18".

2. What should the spacing on the LEDs be? I was thinking about
stagering them for more coverage.

3. How should the current and voltage be made? First calculations show
about 30amps at around 5v per digit. This didn't sound right to me. This
was based on 8LEDs/square inch and each segment being 18" x 2" and this
seems too skinny.

Any thoughts will help before I start spending money on development.

Thanks in advance.
