no

i want to know how to wire them together

i just wanted to say that it does work if u connect led's to the speaker directly it just has to be a 3.7 volt one .. .. . i used one of the normal led's from radioshack here are the specs for it

5mm
3.7 volt
20mA
2600mcd

there you go guy's dual channel mod

im a little bit confused if this tut will work for external and internal speakers(or both) because i plan on putting my psp in a car hehe and im asking if i can get a clear picture of the ground and 5v of the psp in the tut(the pic wasnt clear and i dont wana hit the wrong spot) one last question if radioshack 3mm leds will work or 5mm on it? ill wire the leds in parralel so ya help me!!

you need a diffrent set up for external

yes sir it is for external you don't need to add resistors to the chip just connect the chip to the internal headphone jack

thanks how about the ground and 5v...i need a pic! lol ima edit this later to put a pic u can edit k?

got the ic at my local electrinics shop for us0.50, got 30 k ohm resistor but no 191k ohm resistor,just 180k and 200 k ones, just wanna know can i use those( 180k/200 k ones) instead of 191k?

robin1989:- please dont say hehe, huhu and haha constantly

MaO · « **Reply #189 on:** May 22, 2007, 08:06:14 AM »

can i also use 30k ohms 5% in stead of 30k ohms 2%

yes all the % does is a the variance of resistence means it could be 5% higher or lower

i got teh pics can u mark wer i should get the ground and 5v from??
and wat resistors do i need? 10 or 10k ohms

and btw on the headphone jack wer do i get the + and - so that i could solder it to the chip

zal · « **Reply #193 on:** May 22, 2007, 10:02:43 PM »

tried already, because i have no 191K ohm resisitor,so i replace it with 180K,

unsucessfull,gotta find 191K and try it all over again....

awdracer2, this is mainly to help you, but it will help alot more, i got this help from

~ and im passing it on...

Heres where u get power on the motherboard:

now if you cant see, the red circles are negative, they are mainly all the gold parts on the motherboard, and the one place to get power (positive) iis in the top right, with the blue circle (may be hard to see) but its near the arrow that says Power 2.5 Amp

heres a close up of the area to get power, notice the little solder dot, u can solder directly to there!

hope that helps

thanks alot all i need is the headphone jack soldering points! muhaha but the 2.5 amp positive is 5v right??

i was wondering if this work if the volume is right the way down it its using the psp's internal speakers

Loser777 · « **Reply #197 on:** May 28, 2007, 04:42:55 PM »

I've heard this question asked before, but I've never seen an answer.
Does anyone have the wiring diagram/places to solder for the external speaker single channel mod?

yay i knew it! i did a test like a week ago after i jus woke up with a pair of dead headphones and tested wat connected to wat and those 3 connected to the earplugs

Loser777 · « **Reply #200 on:** May 30, 2007, 03:57:53 PM »

Sorry for asking so many questions, but I am really serious about doing this mod. The blue is - and red is + for two diff channels right? I only need to connect one red and one blue?

Could someone repost the single channel diagram?

Prolly my last question. How much light will pass through the triggers if I don't drill them, only sand them and glue a smd/smt on?

Pretty much the same amount as if you drill em.

Can someone post the diagram for Single Channel again? I just finished soldering the SMT's phew... and I soldered the HPJ to speaker + and speaker - on the chip...

Well, after asking what I should do with some new sample SMT ICs I received,
https://www.acidmods.com/forum/index.php?topic=4928.0
Cyber asked me if I could get SMT Audio Amp ICs, and after some searching, I believe I have found what I was looking for. On order right now I have 3 SMT audio Amp ICs, 2 are stereo, and one is the smaller SMT version of the LM386 IC, so once they are shipped I will start figuring out the exact setup to use to accomplish the sound mod with these ICs. I also recieved some samples of OP AMPs(These arer even smaller than the ones in the thread above) but apon a second look at their Data Sheets I am not too sure they will work

Loser777 · « **Reply #206 on:** June 03, 2007, 04:37:44 PM »

Did my version...
http://youtube.com/watch?v=ZQY5bTK_57A
I'm going to add another LED, but should I wire it in series or parallel? I don't have the wiring diagram...
I am also not sure about adding more LED's, because I kinda want to add more, but I'm not sure about the whole brightness issue...

T3KN1K4L · « **Reply #207 on:** June 06, 2007, 02:50:06 PM »

OK, got my Audio Amps in today, now I can show you all what I'm working with...
First a comparison with the standard LM386 and the SMT LM386

And this one is the SMT Stereo Audio Amp(It's the same size as the SMT LM386)

This weekend I will sit down and get the stereo amp working...

SYSTEM aka (Cyberpyrot) · « **Reply #208 on:** June 06, 2007, 04:20:17 PM »

wow those are way smaller you could probably get 4 in the psp and have internal and external audio dual channels
