Program Spytel Microphone

Dynamic hard capsule, for example, can be drop through the vent pipe from the roof and a flat crystal microphone brought under the door bottom. If these loopholes are not available, use electrical outlets that are in adjacent rooms are sometimes paired. Removing boxes from one outlet to another, access, and through it – to a nearby room. Sometimes it makes sense to drill the wall, making micro-holes, imperceptible to foreign eyes, or use the keyhole. For sophisticated versions of such a specific tonkotrubkovy, or needle-in microphone, the sound is fed through a thin tube about thirty centimeters in length. Program Contact Spytel v.2.0.2 microphone perfect example such a device – an ordinary medical stethoscope coupled (to improve sensitivity) with a suitable microphone capsule, which is connected to a sensitive amplifier. Sometimes, of course, you can do one stethoscope, without any electronics. Very high quality probes are obtained from piezo-ceramic heads, players, or standard pezoizluchateley – electric clock, sonic toys, souvenirs and phones.

Since these devices intersect microvibrations contact barriers, requires very careful to choose their place of application, depending on the specific design features of the wall. Sometimes it makes sense firmly glued to the piezo accessible side of the wall or to the outside glass frame. Excellent acoustic signal can sometimes be removed from water pipes radiators. Improvised resonators Intercept of the negotiations can often be adjacent areas without special equipment, only a coincidence that a glass of liquor on hand (or glass), the rim is pressed tightly against the wall and bottom (butt feet) – close to the ear. The resulting sound is strongly dependent both on the state, structure walls and the configuration of the device material (better – crystal).

There are other options for listening, applying, for example, sent long-range shot 'radiopuli' modulation of the laser beam micro-vibration of window glass, side intercept electromagnetic radiation of radio everyday, non-contact activation of passive microwave emitters … These techniques, however, a professional complex, they are not recommended for use improvised. To create a 'bug' myself, but a great desire, no need to almost nothing. Scheme is better to take out bugs several books (a series of books' spy stuff ") or the Internet. Books contain many mistakes, God forbid, to every other circuit bug worked. Details are best ordered by catalog from Germany choice huge range of prices too. And another negative – must wait 2-4 weeks receipt of order. If you do exactly what the scheme is correct, then immediately buy the SMD components (very small size), if – no, it is best to gather the schema using the normal part, and then transferred to the board.
