Build your own multi wire ethernet cable tester
December 22nd, 2008
If you want to build your own multi wire cable tester for less than $10, Andy Collinson (from zen22132) shows you how to do it. Built with three ICs, some resistors and LEDs — the tester will show open circuits, shorts, reversals, earth faults and continuity. It can be used for alarming, Cat 5/6 cables and more.
