That recumbent healthy, I think, nobody will argue. Well, for fans of technical creativity it doubly useful as it allows you to gain invaluable experience before the greater constructions. Recumbent, about which speech will go, was designed and manufactured in the workshop of young technicians (syt) of our city, together with members of the group. I must say that the idea of its creation have arisen much earlier, but because the materials and most of the parts (particularly wheels) have prepared himself, at his own expense. However, the wheels and the materials are mostly picked up from an abandoned Bicycle, so that the cost was not so great.THE “TOOTHED” WASHER
To lock in the Assembly of the timber frame elements at a certain angle, usually used bolts or studs. For strength additionally use glue, nails, communication “vpoldereva”. Not less strong, however, get a connection using such a “toothed” washers. The advantage of a significant: parse such a mount is only a few minutes.
Aleko not all go to the country on their own cars, the Majority of vacationers travel by bus, tram or train, and for transportation use a trolley bag And shopping and markets, this device makes life easier and very often simply indispensable, especially for the elderly or disabled But the truck can give one more good feature its easy to convert in a comfortable stable chair and then not have to stand even in a crowded transport the entire long journey.
You never tried to bend metal sections “area” or “channel”? If you had, then you probably know how hard it is, especially if the profile is lengthy. Simple drawing mill, made by me, allows you to run a variety of shaped metal profiles with a thickness up to one millimeter in almost any length. In the case are plastic and metals 3 steel grades and the stainless steel, aluminum alloys and brass.
In the summer of 1970, US spy satellites have recorded the emergence of a new aircraft on the airfield Flight research Institute. This information reached the command of NATO, and NATO has assigned him a codename “Betfair”, which translated to English means “backfire”.
Has long been noted that the viewing of slides, movies, TV shows, as well as any other visual activity (reading, drawing, and examined under a microscope), in unfavourable lighting conditions causes a large overvoltage of view.
Paper is the most affordable and “compliant” material for the manufacture of all kinds of toys — from boats-boats and pigeons until such unexpected figures as a jumping frog, about which we want to telling detail: how it is folded from a sheet of paper and through which it becomes movable.
In a vast range of car alarms has recently introduced a good system Mongoose Duplex 3D models with the function of a pager device, remote audio message to the key FOB that the car owner of unauthorized door opening, engine start, shock the body, etc., a Distance alert in the face of massive urban development (on example of Saint-Petersburg, Russia) not less than 300 m. In the daily operation of the alarm system with a pager is convenient because the alarm comes on, the bidirectional remote control unit (RCU) is a key chain held by the owner of the car (except for a loud audible alarm in the vehicle which can be reprogrammed for quiet mode). Thus, there is no need to jump to the car or to the window each time it is triggered car alarms, worrying for his “swallow” (it is known that the set of sound signals of various alarm systems is no different variety). If it works it is “your” alarms — this will be seen by the alarm on your remote-the keychain remote, and the flash indicator LEDs will indicate a specific area of the triggered zone of protection. It agree, it is convenient.
In the manufacture of printed circuit boards have to drill a lot of holes. This is best done on a drill press. But many radio Amateurs it is? But it is not so difficult to do.
