Lit LED Clock?????

Very Nice
Is there a way to change the color instead of red? Or would you have to buy a different display?

Wow, nice job!!

It uses a red blurry filter to display it in red. You can pull the red filter of the white 7 segment housing. Than try to get hold off same matrial but than in blue or green. The lights itelf are bright, a bit to the red, yellow lights. But a blue/green filter will function perfectly.

Thanks, DutchMaster, I may try that.

Yup! The computer looks good! I like it. The alarm clock didn't fare so well though. lol

Cheers!

Usually, each of the display digits are modules, kind like an IC. If you can solder, try changing the red modules to modules of another color... Amber, green, maybe even blue. Filtering any existing red LED display to produce blue colored numbers will simply not work: there is no appreciable blue spectra in any red LED.

http://www.digikey.com/scripts/us/dk...1&Cat=28967682 is a fairly complex array of choices, but the choices get narrowed down fairly quickly by choosing size and color.

Warning: Common Anode and Common Cathode displays are not interchangeable. Research the display module you already have.

Points to learn when researching your existing modules:
Common anode/cathode, Forward Voltage, module contents (is the module giving all digits or just one?), pin arrangements. Best chance for success: a module which is the same manufacturer, using the same basic part number but only a character or two different.... that difference might only be the color.

Post here, some peeps can help. I know how but usually forget I posted things like this, I may not read it real quick-like.... Maybe email or Private message will get thru. Just remind me what the contact is about if or even when you do that.

Is that third wire for dimming?!? Yow!

Well...

LED does not mean Light Eluminating Display, AFAIK because Eluminating is spelled Illuminating.

LED = Light Emitting Diode

Thanks Cody. I was only giving it a guess with bad spelling on my side.

Cheers!

Yeah DunBar could be right about that, but cheap alarmclocks have only lights in the white segment packages which is actually non color specific. But when you buy the IC componenst they already have a filter build in the leds that show the right color. In that case you should get the right color displays. Most of them have a common cathode, but again you cant rely on that.

and the display is most commonly termed as the 7-segment LED display.
