Solve : Cold Cathode Lights - Pulse with music??

1.	Solve : Cold Cathode Lights - Pulse with music??
Answer» Hello, I recently bought 2 Fluorescent case lights for my computer. While installing them, I had an idea; is it possible to make the lights pulse to the music, like lights in a car can? (Clarification: I'm trying to somehow connect these lights to my motherboard so that every TIME sound is produced by the computer, the lights glow according to how loud/soft that is. So that in effect, it would "pulse" to the beat, if music where played). Is it possible to make the lights activate due to sound? Is there an add on module of some sort if not? Thanks, NNJZ (formerly known as Image) EDIT: I've done a bit more searching, and I've found lights with sound modules. But, from I can gather, they light up based on sound detection, causing the lights to brighten from environmental noise. I was interested in a module that would cause the lights to glow due to system noise, so that the lights would pulse to sound generated by the computer even when the speakers are off or muted. I really dont know of any way bedsides the sound module that you can get with some kitsA LED will turn on at 1.5 volts. I don't think flourescent lights can be dimmed very effectively, either.Quote from: BC_Programmer on December 05, 2009, 12:33:26 PM I don't think fluorescent lights can be dimmed very effectively, either. Right. It is hard on them. It has to be a lamp the can be used as a strobe. The strobe pulse width must vary with the effective envelope of the music. You don't want to apply the audio DIRECTLY to the lamp. They make THINGS like that. http://www.eliminatorlightingdirect.com/Lighting_Effects_s/1.htmWhy you would need or want this was going to be my query...

Geek-9pm: Are you saying it would be possible to do with a case light, provided that it is LED? If so, how? The voltage on a loudspeaker has an effective value of about a volt or two at normal sound LEVELS. You could make a voltage couple wish two rectifiers, two capacitors and get a DC voltage that would pulsate from near zero to say four volts. Limiting the current with a resistor, you could drive an array of bright led lamps. I don't know much about the cold cathode things. I believe they do not like to be pulsated, but I am not sure of that.

Hello,

I recently bought 2 Fluorescent case lights for my computer. While installing them, I had an idea; is it possible to make the lights pulse to the music, like lights in a car can?

(Clarification: I'm trying to somehow connect these lights to my motherboard so that every TIME sound is produced by the computer, the lights glow according to how loud/soft that is. So that in effect, it would "pulse" to the beat, if music where played).

Is it possible to make the lights activate due to sound? Is there an add on module of some sort if not?
