Home Made Voltage Detector/Tester (Non Contact)

[@ignatiussilveira4257]

You deserve a thumbs 👍. Your a silent genius. The world needs people like you. Thank you for your work of art.

[@vikrantshinde8433]

Bahut achha video banaya ... editing bhi bahut achhi hai....

[@kabandajamir9844]

So nice the world's best teacher thanks

[@shindvs]

Very good project you made only install transistor vertical then later flat with pcb surface and battery holder readily available in market

[@CrazyCoupleDIY]

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.

[@adamsala9291]

Superb will work on 12v car tester ,👍

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

[@harshsinha8406]

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

[@spacial2]

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.

[@CrazyCoupleDIY]

So true

Nice, the best brother. I make it and succesfully, thanks for you're idea.

Supperb nisar bhaiya

[@wilsonventura5696]

Muchas gracias por tu ayuda 😊.

[@newlife5169]

I used in the past different transistors and it was detecting static from meters away.

[@farasasfar8799]

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

[@wmp877]

Does it work for detecting wire in a wall.

[@hobokaru1350]

What tools will I need in order to build this?

[@sandywoolf2883]

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.

[@pocketoutdoor]

This sensitif from your hand?

[@Jaswinder_singh473]

Very good idea

[@CutieGirl-v7k]

can it find both ac and dc voltage

[@electronicshelpcare]

Wow! Nice idea.

[@asokghosh2876]

Very Very Good

[@pabloapa812]

Que voltaje detecta? Y de que potencia son las resistencias?

[@mominahmed2849]

Very nice

[@amarandos2]

Very good. I will try to do it. Thank you very much

[@sk-ww7jk]

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

[@vishnushankar1412]

How long the battery will work without switch ?

[@Raedva.1964]

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

[@rintupramanik4980]

Nice video

Thanks for sharing! Can i replace bc547 with 2n2222?

[@carlosalba007]

bc548

[@vikrantKumar-gh9xn]

Nice and easy. Good job!!!

[@leyology9613]

Can i use bc458?

HOLA VARIAS VECES ARME ESTE CIRCUITO Y NUNCA ME FUNCIONO ,CUANDO CONECTO LA BATERIA EL LED QUEDA ENCENDIDO

A wire break hua he ke nahi usaka tester he.ya battery or sell bhi check kar sake?

greetings ... I am missing a switch so you don't discharge the battery

[@Ankursamanta]

Is it fake because the light raised to touch everything not only electric floods?

[@Hudsonkem]

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

[@joseluisrodriguez5302]

A ceramic one. Quite a bit expensive but longlasting.

[@dhimanmondal3842]

It is only 100 rs

[@vijayakumarangadigadag1663]

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.

[@rameshrk7531]

I have one question can we do without battery am not a electrical student .......

[@mrprojects6036]

I can use BC548

[@Pixel_Tech]

add cell socket and switch for long life.

[@davidds13]

Doesn't work for me

[@MCsCreations]

Sweet! :)

[@krishnamoorthy.n9874]

Fake one....it's not working

[@surendrabanjare9894]

I tried it but its not working can you guide me what will be yhe reason ?? Thanks in advance

[@faisalmahimi568]

[@choendecce0056]

Its works for DC voltage???

[@addy.is.live1]

Nope

Ye transfer kase sold kiye.

[@nageshgaikwad8895]

24 volt detector ke liye kya karna padega sir

[@lukmankan6452]

Please sir 1m 100k 220r how watts

[@jaganathanv3835]

1/4 watt resister is enough. Switch may be fitted at the back end to increase the battery life.

[@AshokKumar-sc3ou]

Veery good but you don't explain the show the resistance when you put it

[@juncusbufonius]

Looks like the range is so short that wires in a wall would be completely undetected.

[@tusharvirmani66]

first

[@harshmobile2658]

Sir Jee aapne Jo voltage detector tester banaya hai isme transistor ka value nahi dikhaya hai.kripya parts ka value dikhakar video banate.

[@manashbayan3433]

Harsh. .. You can try s9014

[@arjunmohod6022]

Diya hai bhai value bc 547

[@srijandas2748]

Bhai use bc547

[@65castellman]

Solo te falto un micro pulsador para la batería y listo!

[@db5972]

No entendi el diagrama soldaduras cables no se ve bien

[@kamilpol630]

It works :D

[@davidweinreb595]

If I connected the antenna to the knipex pliers would it work(when I cut the cable under power it destroys the tongs)

[@alzaid90]

aap kaha se ho

[@1miltond]

Good video I got a question is this only work with AC ? or it will work detecting DC to?

[@khusenpradhan3386]

it can only detect alternating current as ac can generate magnetic field in an open circuit or single open wire

[@sarveshkumaryadav5399]

Waow nice

[@dhavalpatel4946]

Face circuit not working bro??😂

[@yadrammeenayadrammeena5558]

Yes 220r Kay hair 220e ya 220 one hai

[@akshitchetani3336]

Sir i want 5000 pcs of Voltage detector sensor can you make for me ? iwill pay good amount

[@maurysmartanuragmaurya6832]

What is this 1M and 200R

[@manashbayan3433]

200 R=200 ohm 1M =1 mega ohm = 1000000 ohm or 1000 kilo ohm...
