type of led?

i only want to replace the standard orange led by a blue one. what kind of led is the original one? (thickness, voltage etc...)

tnx

it's a 3mm which runs at 5V(supply voltage) in combination with a 330ohm resistor, don't know about it's forward voltage since it isn't important to know.

So if you put in a blue one you'd better replace the resistor with a 100ohm one or else it might not shine as bright as it is supposed to.

Just replace it with a 3mm 3.3v led, thats somewhere around 6000mcd. Oh, and you don't need to worry about replacing the LED, it's plenty bright. Here a picture.

It's actually brighter then the original orange.

Heres the orange

yep, i agree, the blue ones i use are fookin way brighter than the origianl ones, simply remove old led and insert new on.

how come everyone always loves blue

Because it looks sexy on black. Bright green looks nice too.

done!

just bought a 3mm blue led (no idea what voltage it whas)

it's not as bright as it looks, but it's ok... maybe replacing te resistor will help.

3mm. Woops . I put a 5mm in mine and bore out the plastic light thingy a bit to fit it. Also Janneman, I found something with a bit of reading. You should NOT need to replace the resistor. The board will adjust the power stream depending on the LED or something. Forget where I read it, but it's reasonable. I've tested many LED's with voltages all over the place and they all shine the same brightness (all the same 5000 mcd too).

Mmmhh I doubt that...

but yet again it just takes the multimeter to find out for sure

but you see, the multimeter wouldn't work like an led. If the led can barely handle it, it'll just lower the voltage. But multimeters can handle anything and those points have a max of 5v with the resistor (I believe). So it'll just give you the max. It's like the LED works as a resistor. I'm not sure. Check www.kracker-inc.com. That's where I heard that before.

EDIT: http://www.kracker-inc.com/modules.p...p=viewtut&id=4 It's around the picture where he shows the pin header used as a wire splitter.

i also took a 5MM Bright White one...no complications yet

Sorry to reply to an old thread but I thought I'd offer my input.

The board can't 'detect' and 'adjust' the amount of voltage sent to the LED. It's 3.3v at the point where it reaches the power LED (fed from 5v system power through a 330ohm resistor). That never changes.

In the pictures you linked to, he is using the pin header (quite crudely, but it works) and a 2 pieces of bare wire (probably the legs he cut off the new LED) to make a series of parallel connections for LEDs. This should work without too much loss in brightness, but it may be a long-term risk to the power supply having all these LED's draw so much amperage. I say it's worth the risk, since ... well... it looks COOL!

Eh. I didn't know if it was true. I just assumed so because I've used many different leds and none have burnt/blown out even thought the voltage is all over the place.
