DIY Cable Tester Collection

Here is a Do-It-Yourself collection of projects reference that I have found from electronic project websites for building a simple cable tester of your own. A pretty good reference to study the various design for your ideal cable tester.

Simple Cable Tester 3

LAN Cable Tester

HACKADAY project building your own LAN cable tester.

Using only a simple 555 timer and 4017 IC chip. Very similar to the one above.

XLR Audio Cable Tester

Simple tester circuit to test XLR audio cable, using a 9V battery.

Using 4044B IC chip.

IDC cable tester (Arduino based)

This is a IDC cable tester is more advance using Arduino Mega board. IDC cable is often also known as ribbon cable or flat cable. Typically the adjacent wire to wire pitch is 1.27mm.

This project comes with a big Alphanumeric display to test the cable without needing the tester connected to a computer.

Using only a simple 555 timer and 4017 IC chip. Very similar to the one above.

10/16 pins IDC Power cable tester (Arduino with result display)

This is a very nicely done up IDC power cable tester by Tomarus.

Schematic of the circuitry and the Arduino source code is provided. Driven with a dot matrix display module. Very professionally constructed.

Check out this project here,

Another same project replicated by another electronic hobbyist.

IDC Ribbon Cable Tester circuit

This is a less complicated IDC cable tester with using any microcontroller. Simple circuitry that can check for connection and short circuit in your IDC cable.

There is also an explanation of how the circuit works. This can give you a more detail understanding of designing your very own cable tester.
