How do I make an RJ-45 connector into a hardware loop back device (is that an ethernet jammer in your pocket) ? (or how the hell do you boot an Indy with out an ethernet cable)

Required supplies:
2 strands (short) of coper from any normal cable (such as CAT-5)
1 RJ-45 head
Crimper (or other device to punch down the head)

To create the pocket sized wonder with many uses you simply connect pins 1-6 together with the first strand of copper. Then the second wire goes from pins 2-3.

(Also: don't forget your TIA/EIA wiring colors! Those colors are magical and make this work!)

If you have a fluke tester it will report the device as having a short on pins 1-6 and 2-3. This device is a way to have other devices treat it as if it has layer one connectivity.

The many uses of this are almost never ending.
Some ideas:
