Bought seedlings of two tree-eight-year. Roots are naked without earth. If it sticks? Put all the rules of farming. One soon began to show signs of life and the other is not. I waited two weeks. No movement of the kidneys. I decided to help her stimulation. Brought to the garden plot regulated power supply, multimeter. Plunged to the root of the tree a metal pin with a length of 400 mm (minus). The top of the tree connected to the power supply using the crocodile (“plus”). Turned on the power supply and gradually began to raise the current, but it is more 3 ua did not increase it was Thought that the venture won’t work.
STIMULATION OF PLANTS WITH CURRENT
Old things can be treated differently. For someone this “junk” is worthy only of the dump. But if we threw out less garbage, you see, and the ecology of the planet would not be so depressing. During regular maintenance the hostess decided to change the chandelier, and no amount of persuasion that it can be restored, didn’t help. One argument out of fashion. But to throw out the lamp I did not. Adding diffusers and associated parts, hid in the far corner of the pantry. We had to wait long.
Had dinner, turned on the TV and settled down on the couch by the light of an ordinary crystal chandeliers. Light bulbs and the chandelier sparkle and hurt the eyes, the screen “flashes”! Even one bulb is stopping! And no background light color TV to watch harmful to the eye. Had to cover the chandelier with a paper sheet. Watch TV easier, but it’s not the way out, and fire safety is thus broken! Maybe buy a table lamp, noble lamp, can light a candle. Each option has its pros and cons.
Due to the constant rising costs of utilities, including electricity becomes relevant and economical expenditure. Electric lighting in non-residential premises (e.g., closets, utility rooms, etc.) required most often for a minute or two to take out something you need or Vice versa — to put for safekeeping. But to turn off the lights often forget, and the bulb continues to burn without the need sometimes until the next visit of the premises.
To build and repair electronic equipment needs generators low and high frequencies. A simple device, a scheme which offers the British magazine “Radio Electronics Constructor”, replace them at first. The single junction transistor V1 performs the functions of the relaxer. The value of resistor R1 and capacitor C1 determine the value of the audio frequency (about 1 kHz). It change the selection of capacitor C1. Using an isolating capacitor C3 of the low-frequency signal is supplied to the output socket. And since it has a sawtooth form, that contains a large number of higher harmonics.
Among the many toys in the electronics, is able to mimic the sounds of animals, is very amusing. For example, a toy cow, imitating mooing, or a pig, saying, “let’s Go home, I’m hungry!” The first mentioned industrial products, presentable shaped like miniature soft toys (manufacture of our neighbors from China), electronic device emits a sound “mu-u-u” that can be used for a variety of fun devices, adapting a toy, for example, charm signal in the car.
DEVICE FOR CHARGING BATTERIES is a rectifier device with electronic current regulator (Fig. 1). A rectifier manufactured by bridge circuit of diodes V1 — V4 (Fig. 2), and the electronic controller a current amplifier transistor V5. The necessary adjustment select using the divider resistors R2, RZ, providing current from 4 to 6 And at a voltage of 8-15 V.
The ham-hams is well known that, to ensure reliable connection in addition high-sensitivity receiver and a powerful transmitter is needed and a well-designed antenna. There are many types of antennas, however, have to limit ourselves to just two or three. And one of them often becomes a quarter-wave vertical pin or, more precisely, its improved version, which in radio is called the Ground Plane.
