We are going to make DIY RJ45 Cable tester for incredible cheap.As you know cable testers are really expensive insturments and for people who always works with network it is an essential part.
I will try to help you to build one of them with basic electronic ways.
We will use basic components and methods.The components is going to be easly find in electronic stores.
Ok Here we go Have Fun.

Greetings From Alaska To TURKEY
Step 1: What we'll need ? Scheme
---How is it work ?----
Basicaly 2 connectors are directly connected to battery and leds but they are not connected to each other so we will use UTP cable as a bridge of RJ45 connectors.So if any of Leds are not working that means our UTP cable is not working properly on that Leds so we can troubleshoot on our cable.
I will give the list in 2 parts first is equipments and 2nd is components.
UTP Cat5 Cable (20cm)
9v Battery Clip
Wall Mount Box
Cat5 RJ45 Female Jack x2
Female RJ45 Mount Plate
So now we good to go Lets Begin...
Step 2: Lets Punch Some Cable !!!
Ok here we go;
* First step is cutting the UTP cable from middle.Like 10 cm is going to be Ok.
* When you cut the Cable from the middle take one of em and cut the covers like 2-3 cm from each side.
* Now you will see the cables will be together you need to seperate them
* You do not need to cut the heads of the cables punch down tool will do that job for us.
* Go ahead and take the cover of the RJ45 Female connector
* As you can see there is colors which indicates the proper location of the cables
* Omg same colors with cables which we cut before :)
* Now locate them in proper location you may want to use screwdriver to keep them harder because they always try to go off
* In that part you will punch some cable This part is the most important and the may be only risky part of our project.The biggest fault in the punch down tool usage is cutter site.Punch down tools mouth has 2 sides 1 of them should be Cutter im sure your tool will indicate clearly too.What we are going to do is we will locate our punch down upon the cable but be sure
****CUTTER SIDE MUST LOOK OUTSIDE****
in order not to cut connection between cable and connector.When you all done be sure there is no cable/s hanging sideways of the connector.If there is some cut them manually
*We are done with first connector.
REMINDER : You will need the same thing 2 times so to other connector you may continue the ways again.
Step 3: Make some soldering
* First of all we need to cut the tips of the cables of our connector which we finished.
*When you cut the tips be sure all in the same lenght because what we want to do is we will connect them each other.
*As i said connect 8 cables to each other and check they all touching anycable.
*Now take your soldering iron and solder the resistor to 8 cables which we connected.
*When your job is done take your 9v Battery clip and solder the positive(+) side to end of the resistor.Dont worry about the negative(-) side because we will use it later.
Step 4: Holes to Plate
I cant give any exact number of drill head it will depend on your size of LED what i did is just i take the LED and tried to match the drill heads from backwards with my eyes.But becareful because you dont want to make bigger holes then LED.They will come lose and if you dont glue them they will fell down into box.
Step 5: Place The LEDs to Plate
Now we will place our LEDs to holes which we drilled at 4th step.I used green and red LEDs and i placed them as 1 green 1 red but its your call.Only important part of that step is just be sure negative(-) legs of the LEDs should be the same way inside or outside.They all needs to be paralel to each other.(Check images you will understand what i am sayin')
Step 6: Soldering The LEDs and All connections together
***When you finished to placing the LEDs what you want to do is stretching the negative (-) legs of the LEDs to each other but in order.Like in the pictures just patch them to lower another LED.And After you finished you must have only 1 enterance for negative legs.Solder all of em together.
Semi Step 2
****Take your RJ45 connection which without resistor and battery clip.And take the whole cover from on it.
*Take the tips of the cables
*Place the connector to the hole on the Plate
*And In order solder them to positive leg of the LED which you want to pick.But be sure you did in order. For example " Top left LED indicates BlueWhite on UTP cable" with that way you can test your RJ45 cables which cable is not working or working properly.
Semi Step 3
****Take your first RJ45 connector which with resistor and battery clip . As you remember we left negative leg of battery clip free.So now we will solder it to shared negative leg of the LEDs thats why we connected them each other.Now you can easly solder negatives together.
*Place the RJ45 To other hole on the plate.
Step 7: Final Touch And Testing
There we are last step
*Now plug the battery to battery clip.
*Take a RJ45 Lan cable which you are using on your internet or anything else but which you dont need to test and plug to connectors.2 sides of the Cable should be pluged in Tester in order to test (im sorry i need to say that much basic ) so if your all leds are shining then you did a good job your soldering and other things are fine now you can go to other step
*If its not be sure all soldering are done well
*My suggestion is use hot glue to prevent touching legs each other.
*Now you can place your Plate to your wallmounth box.
*Only thing is screw the top and bottom and You are done.
Take cable which you want to test and plug both sides thats all you need to do.If some LEDs are not working check which cable color are they indicating and solve the problem of your cable.
