DETECTOR HIDDEN WIRING OR HOW TO HAMMER A NAIL INTO A WALL AND SURVIVE.
Hi all. My name is Eugene.
Surely many had to hammer a nail into the wall to hang any picture, and suddenly there will be wiring? Here before me stood such task, how to find the wiring in the wall to avoid damage. And in this video I will tell you how to make a simple detector hidden wiring. So there you go.
For Assembly of the detector we need: three diodes marking part no 2n3904, a resistor with a resistance 1мегаом, a resistor 100 kilo Ohm, the resistor with resistance 220 ohms, any plastic card, led, switch and 10-15 centimeters of copper wire.
The detector will be collected under the scheme.
In the present transistor placed feet, the following: the emitter, base, collector.
Now turn down the base leg back, leg forward emitter and the collector leg to the left and so do all three transistors, it will be our billet. You then need to solder together the three transistor and the leg of the emitter should be soldered to the leg base of the following transistor, or more simply, each right leg is soldered to the middle leg of the other transistor. Then to the leg of the collector of each transistor being soldered to a resistor, which resistance is specified in the video, so these little yellow figures and letters.
Then add in our design the led as shown in the video.
Then to the leg base of the first transistor is necessary to solder the copper wire, we will serve as an antenna, that should work, something like that.
Then take a plastic card and using hot glue to glue our design to the card also solder the switch, sticking a box under the battery and all of our design ready.
And now test. As we see the reaction of zero, yet the gun is not plugged in, but as soon as we put it in the socket, see that the led glows, but the best example I point to the wall where the switch is hidden wiring up. While I am instrument in the area of placing the wires, the led lights up but as soon as drop to the side, it goes out. A very useful thing for those who don't know how in the wall of the cable. And if you liked this video, don't forget to put the huskies and subscribe to the feed, you is not difficult, and I am pleased. All the while.
