A very simple hidden wiring detector. Anyone can collect it. All details are basically available. It is assembled using ultra-sensitive BC547 transistors. The power source is 6V, I personally use dead Krona batteries from multimeter. The arrow in the diagram is the detector antenna.
So, about the assembly:
Because The diagram is very simple, I assembled it with a canopy. The photo shows a diagram with a plug for the crown
It was customary to assemble a housing for it, I took a box from under the ballast of wall-mounted fluorescent lamps:
Then I pasted aluminum tape as an antenna:
I found some 1.5V batteries (I don’t know why) a little thinner than pinky batteries. I took 3 pieces, this is a 4.5V circuit that also works:
I dug holes under Light-emitting diode and the switch (the switch has already been inserted):
I stuffed everything inside and soldered the antenna to the tape:
Here is the assembled device:
But at work_))
Works at a distance of approximately 10cm from the 220 wire
But I'm looking for wiring in the wall))
This device is very sensitive, and I have no doubt that it will surprise you, because... it reacts even to weak electricity. field and the touch of hands!!!
I wish you a successful build!!!
