    i wire my own ethernet...that said it has been awhile. but i udnerstand that you have a couple wires left over when all is said and done when it comes to data transfer. i think two hot and two grounds. however, your dad could be on the ball when it comes to the voltage question.... you might need some clever resistors in the circuit to allow the led to light up. alternatively, maybe you cna leech power from the other wires without affecting the patch cable ( not sure if this is possible) i recommend searching for the instructable of the lamp that runs on old school phone lines

    really nice result, only left to find out a way to use also as eth plug

    my dad told that it is impossible to light the led with the ethernet wire

    If you wired your own Ethernet cable, you might be able to put the cables around the LED, allowing it to function as a cable, and still light up, oh and freakyqwerty, you probably could if you tap the leads to TX or RX, or both (with two different colors), then you might be able to actually see the transmitting and receiving of impulses, might look cool, heres a diagram

    However!: I have NOT tried this, SO...I'm sorry if you do and it
    a) doesn't work
    b) breaks lol
