Very simple hidden wire detector. Everyone will be able to collect. All details are in principle available. It is assembled on super sensitive transistors BC547. 6V power source I personally use dead crown batteries from the multimeter. The arrow in the diagram is the detector antenna.
So, about the assembly: Because the circuit is very simple, I put it together in a canopy. In the photo, a diagram with a plug for the crown
It was decided to assemble a body for him, I took a box from under the ballast of wall fluorescent lamps:
Then I glued aluminum tape as an antenna:
I found some 1.5V batteries (I don’t know why) a little thinner than little pink batteries. Took 3 pieces, this 4.5V circuit also works from this:
I poked holes for the LED and the switch (the switch has already been inserted):
I stuffed everything inward and soldered the antenna to the tape:
Here is the device in the assembly:
But in work_)) It works at a distance of about 10cm from wire 220
But looking for wiring in the wall))
This device is very sensitive, and I have no doubt that it will surprise you, because he reacts even to a weak email. field and touch of hands !!!
I wish you a successful assembly !!!
