I want to make a simple USB light for my laptop. And no, i don't want to buy one because i want to make one-to learn a thing or two.

I was thinking of a simple LED, but I don't know how to do it. Embarassed
I there some thing simple? (no transformators,capacitators...)
I consider this my first hardware hack and i would like some help starting off.
Thanks for reading Wink

Pick the LED you like:

Look in the description for the 5 Volt resistor (the needed resistor is
different for some LEDs)

Wire the resistor and LED as shown here:

Connect it to 5 volt power from your USB cable:

By minutes... Laughing

I should also mention that places like Radio Shack also sell LEDs in small quantities, and please be aware that the store the links are from is my store. Just in case you read this and think there is some shady self promotion happening here... Cool
