I have built a few of these over the years and found that adding a red LED into the ckt allows you to see the light in noisy areas and if you use the light only it does not disturb workers in an office environment. You can add an on/off/on three position switch for switching between the light or tone. The video is very well explained. Good job.
This is a continuity tester not a cable finder .
I agree with you! I used this title because i am using it to find cables.
Continuity tester is what I would call your gadget a signal generator and receiver is a true cable tracer
It's not a very good one. You don't want to pump 12V on any voltage sensitive equipment. A better design would use a transistor or FET for turning on the speaker a capacitive sensor.
Very good! I am very curious how you can use this to find cables that are already terminated in patch panel!
Don't worry, you will learn soon!
Serious?
You wand the port on the panel... Duh
I think you meant a cable that's patched into a switch already????
When I search for a shorted 12 volt circuit to ground on semi-trailers , I place a 12 volt buzzer inline . A live 12 volt line to one side of the buzzer and the other buzzer wire to the shorted circuited wire . The sounding buzzer will stop after tugging , pulling. , or unwrapping the harnesses , then repair . If the annoying buzzer is too loud place electrical tape over the buzzer sound vent . 6/7/23
Instead of a buzzer a 12 volt an incandescent lamp may be used , this lamp will put more of a current draw on the circuit than an LED lamp . Use alligator clips on these fixtures . A small amount of tape quiets the buzzer significantly .
How would you use this in coaxial cable setuup
I have used it sometimes with coaxial cable. I connected the cable finder to coper wire and foil shield of the coaxial cable.
U use 9 volt battery or 4.5 volt ??
I used for the tutorial a 6 to 9Volts Buzzer so i used a 9Volts Battery.
Does it matter where to connect the red and black alligator clip?
No doesn't matter!
Is this only good for finding short circuits?
I am using it as a cable finder due to it's small size and cost but only for low voltage cables.
Where do you get a buzzer box?
On Amazon search for 6-9 Volts Buzzer!
The knipex tools are nice
Yes i like them a lot.
I like your Dremel. Is this Stylus?
Yes! I forgot to add it in the description.
This seems the same as using your multimeter!!!
Great trick for a cheap cable finder. Thanks!
Thank you very much for your feedback!
This is perfect for alarm technicians looking for open circuits. Thank you
You are welcome!
Verry useful...thanks...
You're welcome! Thank you for your comment!
Or buy a multimeter...
You are right with the multimeter you can do the same. The only problem with the multimeter is that the “beeb” is not loud enough. On the other hand this cable finder has a buzzer and it ‘s easy to hear it in a noisy environment. Also it is small and cheap!
How to used 50 meter testing this please tell me bro ?
What do you mean?
The most reliable way to detect a short circuit.
It is reliable and cheap!
Nothing compares to a professional wire tester.
I agree. But also the price is not compared!
Love it!
Thank you!
Thanks! Looks easy. I will try it!
It is easy! Try it and you will have it always in your tools!
This video just only cable tester not Traser
I am using it many years in order to locate cables. It's small, inexpensive and has always a place in my tools!
It's not a cable finder. It's continuity tester.
Yes and i am using it in order to find cables...
I would have soldered wires takes a second lasts forever
That is so true! Thanks for your comment!
The most VFM tool.
I agree!
Excellent! 🙏
Thank you!
Ωραίος φίλε...
Σε ευχαριστώ!
Thats not a cable finder. Thats a cheap ass homegrown continuity tester. Something built in to even the cheapest multimeter. Stop wasting everone's time.
This is not a cable finder. It is nothing more than a continuity tester
It is indeed, but i am using it everyday in my projects in oder to locate cables. It is small and inexpensive. Thank you for your comment!
The video spends too much time in what is obvious.
In general i am trying to create step by step tutorials that anyone can follow. You are right though that sometimes maybe it's too much...
