White led fader

VoLCoM · 27th December 2003, 05:04 AM

I have a question, i'd like to know how to make a led fader with a white led that would be flashing, is anybody have ever seen an Ibook, i'd like to do the same this as they did in the front next to the open button...anybody has a schematic or something like that?

a led driver and a lm555 should do the trick...or the real simple way, a driver and a flashing led in series with the white led.

Apple is also famous for dead pixels in their powerbooks -- word to the wise -- don't purchase your powerbook mailorder -- get one you can actually examine. Otherwise a great machine.

VoLCoM,

I'm not familiar with the Ibook, are you after a fade-on, fade off.... effect rather than simple flashing ?

VoLCoM · 27th December 2003, 03:44 PM

this circuit is for my amplifier, when the power will be on, the led will slowly turn on and off, like on ibooks

ohh...so you just wanna slowly fade on...off??
