Step 2: key chain step 1 : disassembling and cutting the cable
the standard network cable consist of multiple parts, the only two parts we will be using are the insulation and the wires (4 wires to be exact).
disassemble the cable, identify the parts and keep the parts mentioned above.
the minimum length of cable we can use is 10cm because that gives a little tail popping out of the rubber protection. you may use more if you want a longer tail.
choose the color of wires you want and cut them to the desired length.
