This is a great skill to know especially if you decide that you want to persue a networking career sometime in life. For those who have NO intentions on becoming a networking specialist, this is a great skill to have that will save you hundreds to pay someone to come out and do these things for you. You may need to shorten cable, change the location of the cable to a more convenient spot, or you might have moved, and now you are having trouble figuring out where you need to route your cables for your network.
Step 1: Materials Needed
CAT 5 Cable (Length is custom to your project but its smart to have a few samples ready for practice)
Connector/Cable Boots (they make matching color boots for your color of CAT 5)
RJ-45 Crimping tool (found @ lowes or home depot)
A word on your tools:
The crimper i have is a combo tool made by IDEAL that included a RJ-45 die, and a 6 wire Tele. Cable Connector die. it also included connectors for both types of cable and costed me about $50.00 give or take. this will be the most expensive part of your project, but in the long run worth every penny.
