Cable Tester V 2

After making the simple Cable tester as a keyring I decided to make a cable tester, that works without a hub, switch or router.

To make this cable tester you need 2 RJ-45 connectors, a battery and a socket to the battery, some LEDs and a small plastic casing.

The Cable tester is simple. If the cable works, the two blue LEDs light up. To test if the battery works, there is a small switch which, when pressed, makes the red LED light up.

The cable tester works.


I still nede to make the casing.
