In order to organize wiretapping, you can resort to several ways to implement your plan. Electronic tracking devices can be purchased at a store or ordered via the Internet. However, a high-quality industrial design will cost the consumer a pretty penny. As a rule, cheap Chinese devices quickly fail, and they are not particularly distinguished by practicality. One thing remains - to make a bug with your own hands, especially since this is quite feasible, and the cost of components (in order to manufacture one or another audio surveillance device) is essentially symbolic. Anyway, let's get down to business.
Legal Grounds
Of course, it is necessary to understand that special means for listening are the prerogative of special services. In case of violation of the constitutional rights of the individual and proven guilt in an infringement on the secret of private life, administrative punishment will follow. There are cases when it comes to criminal liability. Therefore, do not "abuse" the manufactured product. It is much wiser to use such a device as an additional meanssecurity or use it to exercise acoustic control over the territory of your own home. For example, a home-made bug for wiretapping will be an excellent “informant” if you are not sure about the decency of the nanny you hired or want to know what is happening in the classroom at school. But you never know life situations when the use of listening devices becomes a necessity.
Mobile "GSM bug": an incredibly simple solution
In order to make a bugging device from a cell phone, you need a device that supports the "Auto-Hook" function, you also need a headset (headphones). Nokia 1280 can be considered the most appropriate for such purposes, since the simplicity and reliability of the phone allow us to count on the success of the project being implemented. By the way, a black-and-white screen is a sign of efficiency, the power consumption of the device is significantly reduced. Believe me, such a do-it-yourself phone bug is an excellent substitute for expensive listening equipment. Moreover, literally everyone can do the simple actions described below. Let's get started.
- Go to the phone menu and enter the "Call mode" section.
- Create your personal routine. All items related to light indication, vibration, ringtone volume, screen saver, button press sound and incoming SMS alert need to be deactivated.
- Give a name to the new mode.
- ThroughOn the main menu, find the “Accessory Settings” section, which usually has two sub-items “headset” and “hearing aid”. In each of them, it is necessary to edit the operating parameters and the question of how to make a bug will be practically solved.
- All "accessory" items must be included. Set the newly created mode as active and exit settings.
- Cut the cord from the headphones and insert the plug into the headset jack.
- The display should show activated mode.
We use the smartphone for other purposes
When leaving on a business trip or vacation, you can leave at home a kind of watchman, so to speak, a mobile "guard". And you don’t need to solder anything, and the cell bug is a do-it-yourself converted smartphone. Everything else is just primitive.
- Almost all smartphones are equipped with the "Auto Answer Calls" function.
- Relatively new cellular units have implemented energy-saving mode technology. Therefore, taking into account the known good condition of the device, you can count on 5-7 days of your battery.
- It is possible that the phone is connected to the charger, and a special device with a time relay acts as an intermediary between the socket and the charger. An hour a day is a completely acceptable power supply mode (considering the situation described above).
- Turn off sound notification, light indication and vibration mode in your phone.
- It would not be superfluous to do such an action as installing headphones in the headset jack, since the sound backgroundaround the caller will be an unfavorable signal that will determine the location of the spy device.
- Place the device in the middle area of the living space. Do not forget: the device should not be in a visible place, but a wardrobe is not a solution either. Place the phone on the mezzanine or attach it to the back of a hanging painting.
Bug for wiretapping: do-it-yourself from "improvised means"
As a rule, old phones are not thrown away. Find a long-forgotten "electronic comrade", because it is from him that you will make an efficiently working sound pickup device. It is worth noting that almost any phone can be converted into an eavesdropping device. However, size plays an important role in the "spy life". Therefore, in such a delicate matter as wiretapping, it is better to use small phone models.
Overall flow diagram
- Disassemble your phone.
- Remove the screen and remove all LEDs (keyboard backlight - leave one for visual control).
- Solder the power button.
- Install the device - "Auto-accept a call", because the bug with its "hands" should pick up the phone.
- Replace the microphone with a more sensitive one (electret).
- Build up the antenna (regular copper wire 15-20 cm).
- Solder the battery and fix it on top of the keyboard pad (elastic band, adhesive tape).
- Checking if it works.
The optocoupler shown in the diagram can be replaced with a KT315 type transistor or Western counterparts C9018, C9014. In this case, the capacitor is removed, and the resistor is set with a resistance value of 2, 2 k.
Miniature bug
You can make an FM transmitter with your own hands. A fairly simple circuit will allow you to receive a signal in the radio frequency range of 88-92 MHz. Do not immediately run to the store and buy parts, you may have faulty electrical equipment, from the board of which you can dismantle the necessary components.
You will need:
- Bipolar transistor - 2N3904 or equivalent.
- Resistors - 4, 7 and 330 kOhm.
- Capacitors - 4, 7 pF, 1 and 22 nF.
- Trimming capacitor, nominal value 30 pF.
- Contour coil - winding diameter 6 mm, eight-turn, wire 0.5 mm.
- Material for the board - foil fiberglass.
- 9W Krona battery.
- Electret microphone (most sensitive used in tape recorders).
Assembling an FM bug for wiretapping
- First of all, the tuning capacitor is soldered (middle of the board). The transistor is mounted on the left.
- Moving to the bottom, install (from left to right) capacitors: the first - 4.7 pF, the second - 1 nF.
- Now solder the resistors.
- After - a 22nF capacitor and a frameless coil.
- Finishes the design with wire - antenna, microphone installation and battery soldering.
Bcompletion
Now it is not a secret for you how to make a bug out of your phone and what is needed for this. The variants of GSM and radio products presented in this information review are only a part of the many electronic samples available, through which high-quality acoustic control can be established. However, it should be noted that practicality and quality are achieved through the application of the above recommendations. However, perhaps there will be a "craftsman" who will come up with a more rational way to realize the excellent performance of his inventions of the listening type. In the meantime, we will use what we have. Listen carefully!
