And if the industry had long ago mastered the production of sets of furniture, then pick up otnositelnye lamps is almost impossible, despite the abundance in the shops all sorts of chandeliers, sconces, lamps and floor lamps. The reason is simple: the headset lights are not made.
Snowmobile, manufactured by V. I. Shadrin is not motonarty. The author of the design set out to make winter “Rover” of the Izhevsk motorcycle plant with minimal alteration to improve performance on snow-covered path.
The problem is small but not invented, and most importantly – serious. The negative influence of draughts on human health obviously, and there was low back pain, and sciatica, and lumbago in muscles. The clinics, staffed by modern professionals usually equipped with office chairs and armchairs.
At school, for more than 40 years, engaged in the construction of various mechanisms to facilitate workplace and at home. (In the journal “Inventor and rationalizer” was placed in my article “power saw and pump”, which caused a lot of queries.)
Modelers in different disciplines often have to deal with the problem of determining the speed of rotation of the parts, screws, shafts, and even cassette recorders. That’s what the device advises to use well-known Polish engineer, Janusz Wojciechowski.
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.
Development and manufacture of printed circuit boards for a single instance of a homemade device with a higher density of mounting becomes sometimes a problem even for the experienced radio Amateur. I have also found the opportunity to do without any preliminary layout of printed wiring conductors, and even without soldering electric and electronic circuits. I replace all of that… wrap.

Anti-aircraft guided missiles (AAGM) is located at the junction of rocket technology, electronics, precision mechanics and chemistry, and are the most complex class of missile weapons. Because of this, none of them in the years of the Second world war were brought to combat use, though the development and testing of such systems was carried out in England, USA, Germany and Japan.
