new fat mod idea and attempt

[Cookie Monster]

you know those leds that go up and down to music, well i'm gonna try a put one in my fat only problem is i don't know what its called so i can't get a circuit diagram. 

[Jumbo]

Ummmm, What?

[gamerdude767]

do you mean they leds go on and off to music (sound reactive)?

[zbblanton]

i think he is talking about those lines of leds telling how high the music goes. dont no whats its called tho.

[gamerdude767]

visualization?

[Cookie Monster]

yer like on the psp viulisations but real with real leds

[gamerdude767]

oh i understand it now couldnt this be done with a pulse vu?

[alentris]

That would be sick going up and down both sides of the trim.

[Jumbo]

I think a VU meter could accomplish this.

[Cookie Monster]

no i think pulse vu is just sound reactive i sort of want

[Cookie Monster]

thank you thank you thats what its called. and hopefully this will work

Jumbo is correct its called a vu (voltage unit?) meter. Usualy looks something like this

you would need to make it smt to have any chance of fitting one in the psp. Not sure on a circut diagram brouse around, you can buy IC's which do most of the job for you.

Ya f00 used IC chip LM324 in his vu meter.

Here is a schematic and some facts on it-

I agree with ghost, SMD would be the best way to go. Maybe even make a PCB for it?

[m@DDm!k3]

that would be a great idea to put on the trim except you're going to have a hard time to find a clear trim or u can just drill holes in there and hot glue them to the wall

[GhoSt]

Some Ic's do almost all the job for you like the one jumbo said or one like this...

soz bout all the white space, I only had paint to work with.

try find a smt one and you will have to mount it onto a pcb, you will need a few other components probably.

ok guys this is what im going for. im alright for space coz i don't have a umd drive but i would still like to make it as small as possible so im making a slimed out virsion of one of these http://www.instructables.com/id/SPVJ48HF3JEUCA5/
