\\***//_ Project: Speaker mod | Updated 5/28 -- LOTS OF PICS !!!! --_\\***//

does anybody else think thats a lot of power to pull from one USB
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

just a thought

 

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

 

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 -

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

 

Little update!

 

i like the idea, i think it will look really really nice with all the LED glow and such! rock on

 

Keep modding,..

I really want to see the outcome of this..

 

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.

 

Ques what?! Today.., I really used first time my (fake) dremel and I think I'm in love

I opened my Coce bottle using it, did some nice cuts to the plexis and now I'm going to play whit it again

edit.

Woa! This was my 100th post

 

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



edit. wups 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

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

 

nice idea, well executed so far!

 

LISÄÄ KUVIA....

 

Just you wait.. Tomorrow I'm gonna do all the wireings and such.

But here's one pic, but it won't show to you anything new and stunning...

 

Time for an update!





I used again my mobilephones led to show the glow, BUT soon...

 

This is awsome man, i really want you to put up pics when this mod is ready

 

UPDATE!
