Not only an AC detector, it will react to any interference. The counter is of no use as it's never reset, any MOS gate would give the same result. Decades ago, leaving opened a MOS input drove to its destruction, inputs weren't protected as they're today. You can't rely on this fixture to detect mains. Another point is that alternative current isn't more dangereous for the same voltage, a contrario, because you can feel it, which isn't the case of continuous current. Continuous current makes an electrolisys of blood and produces bubbles in the veins driving to an emboly.
He has used EMI to induce current through unshielded wires but ... The tester may not work across a highly shielded wire or across a magnetostatic shielder
These no-contact detectors never work through shielding. No matter what the design. That is why competent electricians will always use a Safe Isolation Procedure. But a detector like this is an invaluable tool for almost anyone to have handy.
Video is very good. I bought a renhotecic brand test pen not long ago, and after using it for a while, it feels very good to use. It is recommended that friends in need can try it.
nice but better if you place the LED not at the end but let it in and place it befor the sensor it will flash on large part of the pen also pointing will be better add a light switch thank u
Good hein but chize wo ho jo dur se connect kare ,deewar ke par b,jese gore banate hein detecter,kyu ki deewar ke andar jo wire hoti hn unka current check kare ki ya break kaha par hein or LED ki jagah beep ki voice ho so better
He forgot to include a push button. The life of battery depends of the battery you are using, more capacity-more time. This circuit have about 10 mA over 5 Volts this means about 50 mW
Это фейк! Я сделал и у меня тоже при соединеннии к элементу электропитания, как и у автора ролика, сразу загорается светодиод. Как только прикасаешься руками - он гаснет Маленький нажим пальцем - диод гаснет, чуть ослабил давление - диод горит - Круто! It 's fake! I did and at me too when connected to the power supply element, as well as at the author of the roller, the LED immediately lights up. As soon as you touch your hands - it quenches the Little Finger Pressure - the diode quenches, slightly eased the pressure - the diode burns - Cool! I
You deserve a thumbs 👍. Your a silent genius. The world needs people like you. Thank you for your work of art.
Bahut achha video banaya ... editing bhi bahut achhi hai....
Very good project you made only install transistor vertical then later flat with pcb surface and battery holder readily available in market
So nice the world's best teacher thanks

Salam Walekum Nisar Sir yadi Audio ke sath samjaya jata to aur bhi achcha Hota Very Good

Vou fazer um desses👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻
Nice, the best brother. I make it and succesfully, thanks for you're idea.
Superb will work on 12v car tester ,👍

Muchas gracias por tu ayuda 😊.
nice but better if you place the LED not at the end but let it in and place it befor the sensor it will flash on large part of the pen also pointing will be better
add a light switch
thank u
What tools will I need in order to build this?
Does it work for detecting wire in a wall.
This sensitif from your hand?
Supperb nisar bhaiya
Very good. I will try to do it. Thank you very much
Muchas Felicidades Joven Por Su Canal
I used in the past different transistors and it was detecting static from meters away.
can it find both ac and dc voltage
A wire break hua he ke nahi usaka tester he.ya battery or sell bhi check kar sake?
Good hein but chize wo ho jo dur se connect kare ,deewar ke par b,jese gore banate hein detecter,kyu ki deewar ke andar jo wire hoti hn unka current check kare ki ya break kaha par hein or LED ki jagah beep ki voice ho so better
Excelente projeto!
Grato!
Shalom!
Thanks for sharing!
Can i replace bc547 with 2n2222?
bc548
Is it fake because the light raised to touch everything not only electric floods?
not necessary, it works as suppose to, the problem is because it is too sensible, so everything with a charge energy will make it light.
seriously what kind of soldering iron is that? its nice and great vid
A ceramic one. Quite a bit expensive but longlasting.
It is only 100 rs
Awesome it's really fantastic make something new it's awesome
How long the battery will work without switch ?
He forgot to include a push button. The life of battery depends of the battery you are using, more capacity-more time. This circuit have about 10 mA over 5 Volts this means about 50 mW
Que voltaje detecta? Y de que potencia son las resistencias?
greetings ... I am missing a switch so you don't discharge the battery
I have one question can we do without battery am not a electrical student .......
मोगेम्बो खुश हुआ*प्रमोद जाधव*चेंबूर,मुंबई
*Nisar Bhai kitna Sabar karwawongy jaldi se jaldi videos upload karny ki koshus karo Please*
Wow! Nice idea.
Genial tu aporte ni bien tenga un fibron usado lo hago.
add cell socket and switch for long life.
Bhai jan moo ma zaban nahi ha kia
Nice and easy. Good job!!!
Can i use bc458?
Tech Nisar Allah ne aapko bolne ke liye muh bhi diya hai
Sir I am in need of non connected pen testers in bulk quantity. Can u supply the same. Please send me the details of your products n prices.
Can you make it detect 12vac or 24vac?
I tried it but its not working can you guide me what will be yhe reason ?? Thanks in advance
Very good idea
Very Useful bro nice
HOLA VARIAS VECES ARME ESTE CIRCUITO Y NUNCA ME FUNCIONO ,CUANDO CONECTO LA BATERIA EL LED QUEDA ENCENDIDO
Doesn't work for me
24 volt detector ke liye kya karna padega sir
Seu canal e massa
Veery good but you don't explain the show the resistance when you put it
Solo te falto un micro pulsador para la batería y listo!
Good video I got a question is this only work with AC ? or it will work detecting DC to?
it can only detect alternating current as ac can generate magnetic field in an open circuit or single open wire
Trangister ka no ragistence ki value kya h
Very Very Good
Its works for DC voltage???
Nope
Sweet! :)
Fake one....it's not working
Very nice
Nice bro
👌👌👌👌👌👌👌👌👌
Face circuit not working bro??😂
Beleza.pura
Ye transfer kase sold kiye.
Nice !!Like !!
Display wali ghadi se multimeter banao
Looks like the range is so short that wires in a wall would be completely undetected.
2n2222a too?
Sir Jee aapne Jo voltage detector tester banaya hai isme transistor ka value nahi dikhaya hai.kripya parts ka value dikhakar video banate.
Harsh. .. You can try s9014
Diya hai bhai value bc 547
Bhai use bc547
Nice video
Sir i want 5000 pcs of Voltage detector sensor can you make for me ? iwill pay good amount
I can use BC548
मस्त
If I connected the antenna to the knipex pliers would it work(when I cut the cable under power it destroys the tongs)
Please sir 1m 100k 220r how watts
1/4 watt resister is enough. Switch may be fitted at the back end to increase the battery life.
Good video.......
👍👍👍👍👍
Yes 220r Kay hair 220e ya 220 one hai
aap kaha se ho
Waow nice
Good
superbbb
No entendi el diagrama soldaduras cables no se ve bien
Nice...
👍👍👍👍👌🏿
Sir ya m ne bunaya ha lakin is ki light dim on ho rhai ha jasa m battery connect krta hun
Or ya newtral ka btay ga
Sar aap to modal no .bej do me
Aap se conte karna chathahu
Me bi bnaya he par nhi chal rha he

Thanku sir very nice.... nice...ni...
Bhai koi project sahi hua kare to dalo karo nahin to kisi ka bakt kyo kharab karte ho fake video daalkar kisi ka bhi aaj tak project nahin bana
What is this 1M and 200R
200 R=200 ohm
1M =1 mega ohm
= 1000000 ohm or 1000 kilo ohm...
Maury smart anurag maurya BH
Can we make anything to check earphones?
good
Thanks From Jayprakash Raut MUMBAI
Bol ke samjate to acha hota
Too much to ask for the schema is not
nizzzz
Now I'm very happy with it all the
It works :D
3volt not working this circuit
first
Bc548 see kam how sakata hai
