On the shelves of sports stores you can often see elegant double sledge for skiing the mountains, called “Chuk and GEK”. The sleds solidly constructed, brightly colored, very attractive in appearance, but… do not use special demand. We do not undertake to judge how good these sleds, what their shop offers, but after the installation of vasodilates D-5 and they, undoubtedly, will be a very interesting self-propelled machine (Fig. 1). Such a construction was offered by a famous Leningrad artist — N. Abramov. In our opinion, the use of sledge “Chuk and GEK” as a basis for creating various children’s trails in machine — sensible initiative. It should be noted that the possibility of their “motorization” is not limited to the offer, which did N. Abramov: in addition to wheel with spikes, can be applied to the screw or the propeller (in the latter case, it will microaerobic). Finally, why not try it instead of the internal combustion engine to set the motor power cable or contact wire?

Near the base camp in the district of Tsugaru passes along with the tourists, I have built mini-hydroelectric power plant with a capacity of 15 W and voltage 220 V. This is sufficient for night camp lighting energy-saving lamps or LEDs. Day also can charge batteries of cameras and camcorders that can connect a radio or tape recorder.
“Oriole” — so I called built for the son of the electric car. The design idea came to me about two years ago, and much credit for this journal “modelist-Konstruktor”. Several months of estimates, calculations, dozens of layouts, hundreds of paintings and drawings of the body has led in the end to be quite rational, in my opinion, the solution. In the process of development of electric vehicles important issue was the problem of using abundant materials, parts and components, and as it seems, I managed to solve it.
Has long been a regular reader and subscriber of the journal “modelist-Konstruktor”. I want to share one interesting result of technical creativity. Sometimes people ask for a drawing apparatus, a photo of which is posted in social networks is decided and for this reason also more to say about it.
What kind of “aerobatics” not started accidentally discharged the cargo to be hoisted, it will reliably keep a simple but effective lifting device, manufactured by the Leningrad pioneer D. Potemkin. The device consists of a loop sling and guide the rifle with a basic platform and hook. A sling is passed between the replaceable pin of the rifle, grabs the goods at the place of the intended center of gravity and jumped on the hook.
If the village is unthinkable without the tens and hundreds of motorcycles, mopeds and bicycles, in the Northern part of the country, where winter lasts nine months of the year, the role of these public vehicles is increasingly performed motonarty. Without waiting for the industry will be able to meet the needs of northerners, many lovers of the snowmobile technicians design and make your metal samples, sometimes not inferior to industrial.
