I think it’s pretty cool how you did that by strobbing a couple of 555 times through an array of shift registers. All emergency Vehicle Lighting has turned to LED Lighting. Those run on the same theory with the addition of adding output Transistors to give it a bigger push. Nice Approach.

Oooohhhh, pretty lights.
You could adapt this to something bigger using cold cathodes and mechanical relays. Think disco floor.

What I like about things like this is that it gives good ideas for beginner to intermediate level hobbyists. Every single thing on here doesn’t have to be a jet pack or something. An LED marquee is really cool, especially if you make it yourself.

thats all they do is whine i mean if u dont like the hack then fine there opinoin but stop bitching about it you know

the stupid whiners and the led hackers need to call a truce. some sort of stupid, whining led hack?

it was a great hack LED’s rule i can see all the flaming of it if it just sat there but the LED’s chase eachother so its a great hack so “steve” shut up and every one else that is complaning about the hacks on hack a day go out and make your own hack and stop complaning about none.

Ben! Good Job :) Very neat little hack. Could you possibly increase the brightness of the B and K by driving each ‘level’ with a transistor and single current limiting resistor, or even simply redusing the value of the resistors you have used? Cool anyhow.

aghh.. the point of something like this is to show people they dont need horsepower for something useful. I would bet that if you asked several hackers how to use a shift register, they would look at you funny. It is always important to not forget the humble 74xx and 555 chips out there.

As a followup suggestion, I am going to contradict myself and post 33 by sugesting another hack using LED arrays. Simplifies wiring, its rather small, and would likely require a small pic.. but would be a fun project.

Hello all,
Thank you for your comments. The constructive and destructive ones are all helpful for my future projects. Yes, the marquee is simple and pretty straight forward in design. The point was to use it as an office sign, and to make it relatively un-modifiable. I didn’t want my friends and co-workers taking a PIC/Microcontroller out of the sign and reprogramming it, or removing wire-wraps. I do appreciate the suggestions though.

I find it amusing that people can create these interesting “hacks” yet they can’t figure out how to compress a video 10s long to under 4MB. :P

That’s a pretty cool project. It’s Strangely mesmerizing. Lots of other uses for it to… getting familiar with shift registers can help you build discrete logic for dealing with serial data (and thus, more involved hacks).

As for the whiners… If you don’t like what you see do something to change it, submit something you think is a more worthy hack, hack something yourself and submit it. If you have a serious complaint send one of the site admins an email… don’t post comment spam. Not only is it annoying for the rest of us but it’s insulting and rude to the person who’s hack you’re commenting in; it makes you look like a lazy insensitive prick.

If you put half the time you spent writing complaints in the comments with actually finding new and interesting hacks to submit maybe you wouldn’t have anything left to complain about.

Great idea!

Even though its a simple concept its all some people need to get them started on an LED project. Would be great to see a project like this which takes it all a little further. Such as a ‘Manual Input’ Dart board scorer. which allows you to use the LED array (or even better LCD, but may be too technical for this sort of project) along with some PIC based maths to work out the scores!

Anyways, Stop bitching and take the project at face value! Every one starts somewhere and need a kick in the right direction sometimes!

wow all this arguing is really childish. Seems to happen with every hack. i happen to like this hack, even if it’s not technically a “hack”. if you don’t like the recent projects here on hackaday, then build something yourself!

Video link is down, do the LEDs scroll, fade or what?

the idea is good, and the hack is very easy but great!
i like this one, regards
