 How to make a concealed electrical wire detector? Super device DIY! AMAZING!

Homemade non contact voltage tester (Wireless AC line detector using BC547, Simple AC detector).

This is a wireless AC line detector circuit using a bc574. This is a very good simple AC detector for your testing.

Components used in this project:

1.BC547 Transistors x3

2. 3V Active Buzzer

3. 330 Ohm resistor

4.LED

Here's a simple method to make phase tester or break wire sensor at home in no cost, you just need two transistor (547B) Rs.2 each and one LED bulb Rs.1 and one 9 V battery Rs.15

In this video we have made an electric tester in details, which can detect live line/wire and also detect any fault in the live line/wire. It is so simple and easy to use.

learn the science and put it into practice!! Because to operate a machinery it is not enough to read in a book only but practical practice is required.
