so, i'm wanting to make some pretty fancy signs for next year's derby season that will light up. i've got some plans to use some EL wire/tape and the accompanying equipment but i've also got some other sign plans that would probably be cheaper/easier to make using LEDs instead.
so, basic premise is to have a sign that would be able to light up some cut out letters separately and sequentially. i know how to make the sign itself so that's not the issue, what i need is a method to cheaply and easily make the letters light up in sequence.
so it's a 3 letter sequence (let's use D O A as an example) that progresses at the normal speed that you would imagine a large group of people chanting a 3 letter call sign to go. so the D would lights up for a second or two, one-two second pause, O lights up for a second or two, one or two second pause, then the A for a second or two, lather rinse repeat.
i'm imagining that each group of LEDs for each letter would be wired in series, then each group would be wired to whatever circuit would be needed to make the lights cycle. i'm not sure exactly how many leds will be needed per letter, but maybe between 10-20 of them per segment?
i'm going to have several of these types of signs (all 3 syllable chants) so i'd like it to be something that's easy to repeat and not terribly expensive (i'm a derby nut, but there is a line where cost kind of gets stupid)
