Need your help People! (led sound mod)

[ApheX]

Ok, i've been modding a mates psp for him. been fine so far but i've been having some troble with the leds. i'm using the new sound board from wiredinput with red leds. i'm going to have 4 but for the moment i just need 2. for some reason they keep burning out.
i've checked to see if there is any place the could be a short but there is nothing i could see that could cause that. i'm using the 5v point just below the right specker connection and using the wifi swich as the ground. it all works but after a little while they burn out.

Do i need to add a resistor to the 5v point, say a 10ohms one. Hope you can help.

put more then 10 ohms on the out put of the board red leds suck they can only take 2.7 volts unlike the rest witch are typicly 3.7 and reds burn easy

nice one, i don't suppose you would know how much i would need? i only have 10ohm ones at the moment. could link a few up.

try putting the leds in series instead of parallel and use no resistor it should work perfectly fine ..... if you need a circuit diagram let me know....

[ApheX]

but wouldn't that mean one of the leds would be brighter than the other?

[folklord36]

yes it will just burn the first one faser and then when it burned the other will not get current dont do that ive done that before

ok, i'm gonna try three 10ohms and see if that will work. now i've got to wait for the new leds to turn up. thanks for the help, i'll keep you posted.

Hey people! used the 3, 10ohm resistors and it worked. if i was to add another 2 leds to the soundboard would that mean i will need more resistors or would i have to remove one?

[DUKE]

just leave the ones you have on there and just add more LED's

cheers mate!
