The water treated by an electric current, acquires new properties: some of it manifests itself as a weak alkali solution and the other acid. When activated in this way the water felt on animals and plants, it was found that the liquid with alkaline properties were the stimulator, and one that bears signs of acid inhibits the growth of microorganisms and cells of living tissue.
Records of poultry ka large poultry farms and in the farms is no easy task, without automation is not enough. This operation can be performed using the microcalculator B3-23. It is necessary only to add the connector through which the electronic device is connected to the sensor (see Fig.) — associated with a movable strip contact pair S1 (see diagram).
The magazine “Amaterske Radio” (Czechoslovakia) proposed scheme is a simple audio probe to detect logic levels; low (logic 0) and high (logical 1). The device consists of a bitonal multivibrator, is made of two elements of D1.1, D1.2 chip D1, and two keys, collected three transistors V2—V4 (see circuit diagram).
For school discos and Amateur recording magazine “Funkamateur” (GDR) offers a scheme of five “anal stereomixer (Fig. 1). It is designed to connect two stereophonically (X1, x2), two stereos, (XS, X4) and one microphone (X5) for a soloist or a master program.
Device, a scheme which offers the journal “Funk-shau” (Germany), is used to create different sound effects together with musical instruments. It is made in the form of a set-top box or a separate box to AMY. Is indicated in the diagram of transistors can be applied to domestic couples: KT315 KT361 or КТ3107/КТ3102 with any Read more…
It’s tempting to assemble a simple Telegraph device and to communicate using Morse code. Reliable two-way communication is needed in the conduct of military sports games and competitions, in a tourist campaign and in summer camp, it is interesting to set it up at home or at the cottage.
The electric signal amplitude decreases rapidly — within 2-4 s after pinch the strings, it accounts for only 20-30% of the maximum level. At the same time changing the tone color of the sound. This circumstance restricts the possibility of using the electric guitar as a solo instrument. That’s why natural “voice” strings replaced its electronic similarity with a constant volume level. For the first time such a device has used the group “the Beatles”. Now the same email attachment to AMY is known as disturber (deformer), or “FUZZ”.
“I know, I know— says a reader, after reading the title.— Yes, but neither “alive” nor “dead” water does not happen. Tales!..” Is he right? A few years ago, the magazine “Inventor and rationalizer” announced that we have developed a device that allows you to do “live” and “dead” water. And if you speak the language of chemists, water with a very strong acidic and alkaline reaction. It turned out, ordinary water can be decomposed as two components with opposite properties. According to statements of many who have experienced their actions, “living” water beneficial to the complexion, softens wrinkles, improves hair growth, reduces hair loss, is a good remedy for burns. But “dead” water bad acts on the mouth, reduces gum bleeding.
Many motorists available means, to improve the performance of various components of your machine. Considerable help in providing them electronics. To take at least a variety of electronic ignition system, which “M-K” repeatedly told. Today we offer the owners of “Lada” and “Cossacks” to build a simple electronic voltage regulator (ZRN), constructed in Kharkiv by B. Krutikova.
What motorist don’t care how secure your vehicle against theft or intrusion by unauthorized persons? Here, as a rule, comes to the aid of electronics. However, most electronic devices designed for protection of vehicles, often complex and expensive; moreover, they often need isolated from the body of limit switches. This limits the wide application of such “watchmen” motorists.
