Sound Reactive Cold Cathode

[blackburn]

Hey, guys alot of you may know me (or may not  ) from the PSP section, well i just got a 360 that I modded and everything, but i was wondering, is there a way to hook up the cold cathode's inverter to the point on the motherboard for audio? (Hope this makes since)

[psppunk]

if you can dim cold cathodes then i dont see why not
probably gonna need an opamp

[blackburn]

opamp? i asked ryan0 about it he said to use an lm386 and solder one of the audio outs and a ground point to the audio + and - of the lm386 i just dont know if i need to add 12v to the Voltage Supply on the chip or not, and if i would hook up the ground or the 12v side of the inverter to the Output of the lm386

[psppunk]

an lm386 is a type of opamp chip
im not sure about all that =/

so the cathodes will bounce to the music like the psp mod kinda? if you get it to work a tut would be greatly appreciated :P

[psppunk]

ok, just tell me this... does a scanner use a cold cathode lamp or flourescent or what?
if it uses a cold cathode, ill test for ya =P cause i just ripped open my scanner

[Winterz117]

i dont know if they are cathode lights, but they run on a 12v source so you could use them for a test

[blackburn]

i do believe a scanner uses a cold cathode but it would be very delicate becuase i dont think that it is in a plexi/lexan case like ones you buy from the store are.

[psppunk]

yeah, it is really delecate... im keeping it in its case that the scanner had it held in
now if only i can figure out what the wires on the board the drives it (inverter board?) are for
theyre color coded [black, brown, red, orange] idk if maybe this is a standard thing or anything like that

[blackburn]

im not sure, have you looked online?
