A little thing you can do with an old computer mouse

Hello guys, i had a bit of free time so i decided to use it to do somthing and i made this

(Sorry i tested it on my ps3 since i don't have access to my pc wich is why i have free time)
This is a littel lamp you can use to iluminate your keyboard by putting it in free usb port
What you need :

• led 3v (i recomand white if you are using it just so you can see the keyboard in the dark)

-a little resistance to be safe

-tape

-usb cable of an old computer mouse

-a little thin steel road

First you can remove half the plastique part of the usb cable to make the wires visible and remove the green and white ones as you don't need them for this , second you cut the visible red wires leaving just a little,

third you put the resisintance part in the little part you left visible and the other with the one you cut and cover it with tape like so,

fourth you put the led lamp at the end of the wires (red is positive(+) black is negative (-)),

now you tape it all carfully,

Finely you tape little steel road to the wires.

Well that's it( ofcourse remove any extra parts).

Hope you liked it enjoy :)
