Agar 3.7v lithium-ion battery use Karen to buzzer kam karega aur resistor konsa lagega, 330 ohm's hi rahega kya?
Please reply I will make it.

[@shaikhamiruddin5848]

Please reply
9 volt ki battery jaldi khatam hojati ha, aisa ho k 3.7 li ion battery commonhai aur mobile charger bhi use karsakte hain,main jhalar ,decoration light banata hoon, usme fault pakadne bohut aasan hota hai.

We want the deep observation about the live wire in the wall, because many times we drill in wall for other work, we damaged the live wire, how we can increase the efficiency of this product.

Your explanations are simple easily understood and wonderful. Reminds me of an old saying in my language "If a person can explain in simple language complex things then he is like an aromatic gold flower"!! meaning gold flower is great to look at but no aroma but then imagine how it would be if it has a fragrance also.

[@TEKNOISTIX]

No
That is totally different

[@shrinik1969]

Can this be used to detect body voltage thats AC and will be in milli volts? This can be a great tool for anyone to check how our body is getting charged when we are near electric source. Very good work keep it up

It is based on capacitance
If you touch the antenna it will beap slowly

[@susantpal]

Very well explained. I made the Circuit exactly as per your guidelines. But unfortunately, the LED and Buzzer get active and on as soon as the 9v battery is connected - without any electrical wire nearby. It doesn't stop till battery is removed. Please help in solving the issue.

[@susantpal]

Later today:... I slogged for several hours to find out where I went wrong. Finally, after several experimentations, I succeeded in solving the problem. The circuit is doing exactly the way yours did. I am happy and wish to thank you again for this creative and useful DIY post.

[@sagarmahato5542]

[@shrinik1969]

Another qn..why we need battery? Can the electric pulse that attena picks up and which is amplified by series of transistors- light the bulb? Is that too low current to do the required action?

[@MohitKumar-dn5sh]

Sir ye neutral me kaam kyo nahi kar raha hai

[@TEKNOISTIX]

Jab koi device connect hoti hai tab phase ghoom kar neutral me jata hai
Otherwise neutral me koi current nahi hota

[@francisdias9487]

Sirji, I just watch another video. The circuit is same with 3pair of 3volt batteries. I am confused to know that your diagram shows the collector as negative battery connection, whereas in some videos, the collector is shown as positive. Pls help.

[@tejsgaur1245]

Dear sir mene youtube se kafi circuits dekh ke banaye aur lagbhag sabhi kaam bhi kar rahe hai par is simple circuit men dikkat aa rahi hai ek to ye ki jab isko power dete hai to ye apne aap led aur buzzer on ho jate hai bina kisi signal ke aur kafi loud bhi hai to test karna sambhav nahi ho pata aur jab isko 9v ki bajay 3v de tab ye kam jagke fir signal dene par tej ho jata hai... Aur par ismen neutral aur phase men koi antar nahi aa raha... Iska solution jarur batana aap chaho to mujhse WhatsApp ya email se iski pics aur le lena par kaise bhi isko sahi kijiye.... Kafi pareshan 😩 kar diya hai isne... धन्यवाद 🙏

[@TEKNOISTIX]

There might be some reasons
1. You must put the circuit into a plastic box to provide isolation
2. Reduce the antenna length because more the antena lengrh the more it is sensitive
3. Any wrong connection
4. Defective transistor
