Creating Bar Codes

I'm messing around with a project for fun and I'm wondering if any of you guys know a great way to make a realistic bar code/UPC image with the thick and thin, black, vertical lines aligned up horizontally? I tried this approach into creating one, but it just wasn't working for me. Here's the method I tried to use (in case some of you have a similar method).

1) Layer 1, start with a white background (hope I didn't lose anyone with this step ;P).

2) I added a Noise filter with the settings of Monochromatic and Gaussian Blur at 400% on Layer 1.

3) Then, I applied the Motion Blur filter 90 Degrees and had the distance set to 999 pixels.

4) Then, I tried to do some adjusting with Curves to brighten it up because before this point, it was just a black and gray image.

And this is where I came close, but no go. I haven't been able to turn the gray into a solid white and I tried using the Magic Wand tool to just select the gray areas and fill them in with white, but that didn't help cause it was blurry and it wasn't all one shade of gray. Any help or if you know another method is doing this will be helpful. Yah, I could just use the line tool and just create thick and thin vertical lines all the way across, but just wondering if anyone else had a better method. Thanks in advance.

well...If I need a barcode, I just simply draw it myself.. It really isn't THAT much to do..lol. Just marquee some random thickness bars, and in the end 'crop' them vertically to match. And make a begin-bar and an ending-bar. And add the numbers there under them.

Either that, or just use a font. I have a barcode font, and it's ok.

hehe yeah! marquee tool
or pencil

Yah, I know that I can just go in and draw them with the Marquee tool, but if there's an easier (lazier) way, then I'll use that. ;P

Well, ok, I'll go in and draw them, but that'll have to wait until I get back home tonight from work. Just tried doing it that way to see if I could that portion done before I had to leave which was like 15 minutes ago. Thanks anyway, guys.

sweet jesus how much easier than a pre-defined brush/shape could you get!

Barcode fonts...

if you know how to make a single row marquee, fill it with b&w noise, deselect and strech it, you have a unique fake bar code.
