HOW TO – Make your own Ethernet “splitter”

Chris writes – “With an Ethernet “splitter”, you can simultaneously connect two computers (or other network devices) on one Ethernet cable. You can buy Ethernet splitters for approximately $ 20.00 USD but you also can make your own. Context: One office, one ethernet jack and two computers, or One living room, one ethernet jack and one HTPC and one XBox. If you can’t realistically (without tearing apart walls or renting a scissor lift) pull one more ethernet cable from the patch panel to the office / living room etc. you can consider the use of an Ethernet “splitter”. I’m assuming all the four pairs of the ethernet cables are properly connected within the ethernet wallplate and the patch panel.” – Link.
