Good day to all! ... I did not remain indifferent to a simple lock on the jumpers! ... I apologize to the author of this miracle ... for him 3 minutes to hack ... In the 90s, the guys developed an anti-vandal in the "problem" copying of a key card. The principle is simple: a card from two halves of plastic with 30 mini conductors closed in a ring. It is stitched on a stray with a mirror arrangement of coils with the ability to create a large impulse, as a result of which the corresponding "ring" is broken. The principle of the castle to the disgrace is simple. In the “receiving device”, a cutout under the card of which is located at the bottom of the lock, a card is inserted with the corresponding encoding of the lock, the location of the “broken” and the remaining whole short-circuited rings, when the card is completely immersed in the receiver, the mikrik is triggered and when the card and lock coding coincide completely, the electromagnet works.
... by supplying power to the lock circuit only when the card key is inserted, battery power is possible ...
garage out of the way
country house ... Another advantage: the card is not afraid of demagnetization and is quite resistant to mechanical stress.
... Sorry, but in order not to feed the Chinese ... they are so fucking good and still a little secret only in vlichka)
There is also the experience of efficient garage heating with oil working out with the possibility of receiving a certain voltage in parallel ... About the "partisan bowler" from which it was possible to power the radio, I think every time I heard it ... But my opinion is that the principle of MHD is more interesting. ..
