Fade to black endo-eyes?

[Maelstrom]

Okay...So how do I do this? Got a lot of great soldering and led tips from my last thread regarding the Ironman Arc Reactor.

Is there an easy non IC method of doing this. I assume it will involve a capacitor of some type. Any online schematics or prebuilt kits out there? I found a lot of LED faders out there, but I think those just fade in and out.

Looking for something that will be on with the switch on and then fade to black when I turn the switch off.

Thanks in advance for any help/ideas!!

Nobody? Come on and help a guy out. At least a point in the right direction or tell me to go sit and spin or something :lol

Since I don't know exactly what you're looking for I can only say that a PICAXE chip could be programmed to ramp up LEDS to full on when a switch is activated, then ramp down to off when turned off. As far as rate goes, you would have to tinker with the program to get the look you want.

These chips are pretty cheap and easy to program. They would work good for many prop projects. Here's a start:

Theoretically, it could be done with current limiting resistors and capacitor(s). I'm assuming you're talking about the effect like in some newer cars, where the dome light stays on for a minute or two, then fades. Of course, without a lot oftrial and error, I couldn't tell you what size capacitor you'd need, considering you'd likely be draining the capacitor at 10mA or more.

Good luck,

Take a look at this

this should work

fades LED in and out (so by pushing fading out and when open fading in)

if you want an fading in by pushing and an fading out by open more work is needed

Here is my solution. More than you asked for, but fantastic.

Let me know how it works for you. Mine is awesome!

If you just need it to fade out then a capacitor will do the job. I did it for my Arnold bust with the help of Tony Plutonij who told me what I needed. You can see the fade out effect at about 2:38 in my video.

I don't understand wiring schematics, but my son did. You need your LED, switch, power, capacitor, and resistor. I can get you more information on how it all wires up when my son comes home.

Thats cool Al......love to do that with mine
