Recently born, the guitar has managed to acquire its own history. At first it was a simple hybrid between a conventional housing with a wiring diagram. Then came the so-called “Board”: the whole guitar was a actually one exaggerated upper deck. “Board” has received the widest distribution in the world… and gradually disappointed many musicians.
SENSITIVE METAL DETECTOR
The metal detector I designed operates on the beat frequency principle, which arises from the difference in oscillations between the reference and the tunable oscillators (typically the 5th–10th harmonic, whichever is closest in frequency). This design allows the detector’s sensitivity to reach a level where it can detect, for example, a five-kopeck coin buried 10 Read more…
Unfortunately, on vehicles of most episodes of “Zhiguli” are not put neither ammeters nor voltmeters, although sometimes there is an urgent need to monitor the battery condition. Produced by the same industry switches instrumentation is bulky and unsightly, and the price is commensurate with the price of parts developed by me homemade digital voltmeter that allows you to control the system voltage in the range of 10-16,3 V, accurate to 0.1 V.
People sometimes just have no time to twist knobs of the receiver to switch from one frequency to another. Here comes the advance settings of some of the most popular stations, pressed a button and listen to the desired program. In this mode you will be able to work any long-wave radio with a homemade console, designed for several fixed frequencies in the range of SV.
Existing acoustic system (as) furniture type mostly rather cumbersome and expensive. To use them when testing and setting the audio uncomfortable. And in ordinary surroundings while listening to the radio and music are often given preference more simple and accessible to speakers of small capacity, including homemade, produced from scrap materials.
Many people when buying a new and advanced gadget I hope for a long life, but in reality it is not so. Due to the fact that the tablets are technically complex device that causes of failures can be many.
Units, tens, hundreds, thousands… This system of accounts, familiar with first class, it seems to us the simplest and most convenient. However, the decimal system is not the only possible one and not the universal. To write numbers in the binary system needs only two digits: 0 and 1. This is a big advantage system, binary compared to decimal. Thanks to her computers and cybernetic devices have their own language that was ideally suited for electronic circuits, relays, diodes, transistors.
