Where do you get your electronic components?

thanks guys, I like digikey. Some good prices.
I'm lighting the buttons on an xbox 360 controller and I need resistors for the led's.

Haha I just don't need 100

i have resistors out the ***, what value do you need? wattage?

not exactly sure yet ordered the LED's but don't have them yet and i need data sheets to figure that out.

Speaking of this, anyone know how touchy they are? Let me explain...

I'm putting an LED behind each of the ABXY buttons. each the corresponding color. (red, green, blue, yellow.)

Each of the different colors has slightly different voltage and voltage drop, but the same recommended current and I carefully picked them to be as close to equal light intensity per voltage.

Under these circumstances considering the voltage is only around 3 volts. do you think I'll even need resistors wiring the LED's in parallel? I'm thinking I'll only need them to fine tune the light levels to match I actually have a light meter but I'm thinking I'll just have to eyeball it with the light being different colors. plus my meter is only in foot candles, Milicandeli might be too fine.

uh huyuck! so funny, ur like a comic genius man!

He wasn't kidding. I have one right down the street that sells singles of everything you could imagine.

Question:

Before you ask me to post this on an electronics forum... I have. They are smaller and take forever to reply. so if any of you know anything about it don't hesitate to share.

So my basic understanding is that the supply voltage will be 3v ± a little if i'm using batteries, or 2.4v if i'm using the rechargeable battery I bought. I ordered the LED's but I don't have them yet so i don't have very specific info about them but here is what I do know:

1 Blue: Forward Voltage Min/Typ - 3/3.2V @If=20mA

1 Yellow: * Forward voltage: 3.3 V Typical * Forward current: 20mA

1 Red: * Forward voltage: 3.3 V Typical * Forward current: 20mA

1 Green: Forward Voltage (V) : 3.4~3.6

How would you wire these so that they light at the same time from the same power source. I was thinking they should be fine in parallel with resistors just to equalize the light output between the different color lights.
