Interactive L.E.D. sign websites

13 posts in this topic

Thought I would share these with those of you who are unaware.

First we have http://www.internetledsign.com I've been using this one for like a year. We had a thread about it on the old board. I finally paid them a dollar so I could post stuff on the bottom sign. This ones located in Canada.

I recently found out about http://www.notallmine.net/cam.asp which is a smaller sign you can just send two lines of text to. The positive side is that the cam is streaming unlike the above site that takes an image every so many seconds. This ones located in Chicago.

What would be really cool is to have our own thing people could send messages to. No L.E.D boards just a computer monitor with a web cam pointed at it. Create a page with a text box where people can type something in and then when they click a send button it displays it on the monitor the web cams pointed at.

I've only seen this done a couple times before. One was for a glue company. They glued a CRT monitor to a wall and had a web cam pointed at it. Underneath that you could type something and it would display it on the monitor. The gimmick was to see how long their glue would hold.

It would of course take custom coding to accomplish this. I researched freelance programmers but they seem to want an arm and a leg for everything. If we could find somebody that would do it for free or cheap that would be awesome!

If I recall correctly, monitors and tv screens don't take too well to webcams. I seem to remember trying to record a short video of my TV for the fun of it and having it full of non-existent wavy lines and bars.

That aside, you'd have to bump up the font pretty dern large in order to some text on a monitor to show on a webcam if it's zoomed out enough to see the whole monitor. Maybe instead of a text box, the ability to post images?

Yeah, thats right,the progressive scan on some monitors prevent you from recording it...

Oh good... so I'm not hallucinating or going insane just yet... for a second there I was doubting myself.

Thats what happens with CRT monitors not LCD. Video cameras run at a different speed than CRT monitors thus when pointed at one another you get flickering and or horizontal bars scrolling down the screen. See the video camera picks up the monitors refresh rate which is invisible to the human eye. Thats why the monitors in the background of news casts appear the way they do for example. I don't know the exact mechanics behind it but its something to that effect.

But anyway yes it does work as its been done a couple times over the years. I did some heavy researching the other night and was able to locate the old website addresses of the sites.

Here is the one where they glued the monitor to the wall as mentioned in my first post. The glue held for 123 days, and the only reason it fell off the wall was because somebody bumped into it by accident I remember.

That link no longer works so heres the Internet Archive entry of it.

Here is the one where they used an LCD screen. This was probably the first person to ever do this using one. sadly it was only up for less than a year. I remember that I did use it.

Last but not least here is the most important one. As far as i'm aware it was the first ever and had the longest running. Plus it was the most fun in my opinion.

After spending hours researching this I think it can most easily be done with an l.e.d sign. Theres new hardware technology that lets you connect them to the internet. The software might be able to be manipulated and turned into a website so that anybody can send it messages.

Though the whole thing is still pretty complicated and very costly. Then on top of that I don't even know if it will work. :indifferent:

Well, i think could take care of the "sign" part, since i know a lot about electronics, but i think it would just be easier with a cheap monitor and a webcam

getting any of this to work hardware wise is the easy part. The hard part is figuring out all of the programming thats needed and then writing all of the software from scratch to get it to work.

i hav a video camera that u can plug into your tv/computer and it records everything thats on the screen so you dont have 2 zoom in and out 2 get a perfect shot and it makes the quality a lot better. u can then plug the camera right into the usb port on your computer and download the videos. also i have a 36" computer screen in my living room so i could just go on word and make the backround black and hide the toolbars. when someone submits something i can pause the camera, type it in, then play it. it has 1 wire and port 2 plug into the monitor and the other plugs into the usb port but the only thing is im not sure if i can make live feed so we might have 2 write something on the website that says "thank you, your post will be uploaded in a little while" or something like that. lol...just a stupid suggestion...
