oh, hi i have two 5mm blue leds trhat i got from radio shack, i plan on powering them both up in my mouse.

I realize i can get the power direvtly from the mouse, from that little...chip thing.

However, i fear that too much power going through there (two leds) could short out the mouse, or something.

So, does anyone know if i can hook both up directly, or i should send both going down into a resistor, then into the chip.

I plan on soldering the leds to the chip, if not to a wire then to a resistor then to the chip

We need to know the voltage rating for the leds. That is the minimum info and usually with that one can judge if the resistor is needed.

Sure, (this is Zero*Star) i have two blue led's the specs on them are:

5 volt, 330 mA, 300mcd

So, my question is now, do i need a resistor, and if so...what kind?

my first tip would be to get a voltometer. Ther're cheap. you can get a cheap one for $10 USD that will do more than you need. Power on your mouse and search for the +5v and ground. They should be two of the wired going through the cable. because they are 5 volt LEDs you'll need to wire them in parallel but you won't have to worry about resistors.

+5 ````` ground

Ignore the ``````
