The simplest DIY hidden wiring detector

Hello, dear readers and homemade products!
Perhaps some of you have already had the sad experience of solemnly hitting the power wiring while drilling the walls. The consequences of such activities, in addition to the beautiful fireworks, can even be very sad. So, before performing the installation work, it is advisable to clearly determine the position of the cable routes in the walls.
In this article, the author of the YouTube channel “DIY Pro” will tell you how you can make a hidden wiring detector.
 The simplest DIY hidden wiring detector

This homemade product is very easy to make, and even a schoolchild can easily repeat it.
Materials required for DIY.
– Li-ion battery 6F22, 9V (crown)
– C945 transistor (set of transistors)
– Resistor 1kΩ (set of resistors)
– LED
– Solder , copper lacquered wire 0.5 mm, wires.
Tools used by the author.
– Electric soldering iron with temperature control
– Tweezers
– “Third hand” with illumination.
Manufacturing process.
So, the main elements of this device will be three C945 transistors. C945 transistors can be replaced with 2SC3198, 2SC1815, KSC1815, KSC945C, KTC3198, C1815.
These transistors are available not only in TO-92 package, but also in SMD (planar) version, which will allow miniaturize the board more.
 The simplest DIY hidden wiring detector The emitter, collector and base pins are located as follows.
The simplest do-it-yourself hidden wiring detector An ordinary red LED will serve as an indicator. The long leg (on a new product) is a positive contact.
The simplest DIY hidden wiring detector Also required a 1kΩ resistor and a “crown” battery connector. The polarity, unlike a battery, is reversed.
If you often assemble or repair various electronic circuits, it is better to purchase resistors, capacitors, and other frequently used elements in the form of such sets . < br> The simplest DIY hidden wiring detector  The simplest DIY hidden wiring detector The antenna requires a piece of copper wire 0.5 mm in diameter.
