    does anybody else think thats a lot of power to pull from one USB :worried:
    i was gona do a mod and use USB power but i was told you shouldn't draw alot of power through the USB port or it would kill it :duh:

    just a thought :thumb:

    Nah wouldn't pull alot.. its only a few l.e.d's.. Think things like webcams, cordless mouse receiver thingy's would probably take more..

    If it does mess up your USB though.. you know it was to much :rock:

    Thats why he has the recistors (I dunno if its correct)...

    The recistors give only the power threw, that the leds need...

    You should paint the mesh blue, or something else...

    Everything OK except I believe the long leads on the LED are positive (+) and the short leads are negative (-). You seem to have them reversed.

    BTW keep the grill Shiny!

    Thank you that you confimed my connections and that that the long leads are + and shorts ones are - :D

    BTW. I'll keep the grill shiny and I'll add some nice "bling bling" details :hip:
    Hmm... Should I mod also the subwoofer :) Nahh! I wont :yawn:

    i was looking at your diagram, and i've realized a problem. you have a 47 ohm resistor in front of 8 leds. running off 5 volts, you would need a 12 ohm, .5 watt resistor.

    E = I * R
    1.8 = .16 * R (if each led draws 20mA)
    R = 11.25 ohms next standard resistor = 12 ohms
    P = I * E
    P = .16 * 1.8
    P = .288 watts next standard value = .5 watts

    at 30mA per led,
    E = I * R
    1.8 = .24 * R (if each led draws 20mA)
    R = 7.5 ohms next standard resistor = 8.2 ohms(if i remember off the top of my head)
    P = I * E
    P = .24 * 1.8
    P = .432 watts next standard value = .5 watts


    so, unless i'm seeing this completely wrong, and i like to think that i'm not, then the resistor you chose is MUCH too big. please correct me if i am wrong

    There's no actually 8 leds. There's only 2 of them becouce the I've split the wires to go only 2 leds so I would need that 47ohm resistor.

    ok. but if you're going to have 4 sets of leds like that, then you should still use the sizes i posted. if you're going to only use two per resistor, then yes, 47 ohm resisotor will be the one.

    I thought that if I connect the wires like this it would be more secure.

    [​IMG]

    edit. wups :D The longer lead is (+) and the shorter one is (-). Little misstake.

    It doesn't see in the pic, but every led has it own resistor (100ohm).
    I woun't be able to do the wireing tomorrow (actually today) because shops are closed and can't buy the new 8 resistors :grr:

    And! I did something today. I drilled all the holes to the speakers for wireing.
