I built most of the vehicles are based on commercially available motorcycle or bike noisy and power hungry internal combustion engines. It was with one hand comfortably, and the other is very troublesome, as the quality of the engines met rarely and had a lot of energy, and most importantly, time to spend on their completion and debugging. That’s why you always attracted to the idea of use as power unit of electric drive. Knowing that there are pros and cons, first and foremost, difficulties with the power source, the version of electrocycle always left “for later”. But first the absence and then the high cost of gasoline has forced to revisit her.

CORD SKATER
This cord pilotage has an excellent management system and has excellent maneuverability, which allows it to perform the most complex maneuvers. And most importantly – it never loses connection with the pilot due to robust tension cord at any point of the flight hemisphere. The design of this model is quite original and in many ways not consistent with accepted standards. In order to design such models, it is useful to get acquainted with the principles of determination of main parameters cord pilotage.
SOLAR STEAM TABLES
The picnic, which happened to be with friends, will be remembered not only by the abundance of impressions, positive EMOTIONS, but also the uniqueness of what and how food fueled its organizers. After all, improvised marching steam tables this time served… cardboard box from under the computer, pre-laminated on the inside with aluminum foil. And as unconventional source of energy has made itself the southern sun.
THE MOUNTAIN BREEZE
Not so often at the winter tracks and the hills will meet snegohodnomu homemade equipment for children. This is mainly well-known industrial design of the “Chuk and GEK”. On some have low-power internal combustion engines. For all its obvious advantages, they also have disadvantages. However, avoiding discussion on the topic of “for” and “against”, look at the unusual layout of sled-monoskis with the motor.
“SCHEMATICA” CLASS B1
Proponents of class rezinomotornaya expense of building a traditional model B1, do not turn the page of the magazine, seeing the drawings of equipment, by the external signs relating to the child “schematical”! Overcome the neglect of long ago you passed the scheme and read the material. You may find many interesting things.
WALL GREENHOUSE
Every gardener seeks more efficient to heat your greenhouse. One of the best methods of utilization of solar heat, nakaplivaetsya! on South or East wall of the stone house. To build eliteplace is quite simple. Primarily along the walls of the house dig a trench depth of 1.1 m and a width of 0.8 m. It forms the track along which you can walk among the plants. The rest of the greenhouse is a garden.
STRAPS LUGS
Which only tricks nor embark on the owners of automotive vehicles to prevent wheelspin, maximize traction from their mechanical helpers. Here and further weight gain traction at the expense of baletnogo of the goods and the transition to large diameter wheels and use of special (wide) tires with special raised tread, and even such non-standard technical solution, as a partial filling of the pneumatic chambers with water (“modelist-Konstruktor” No. 2, 1993). And, of course, vehicle wheels lugs, and a wide variety of designs.
ONE POTATO, TWO POTATOES
“Potatoes are often called the second bread. Only easy this bread gets. Especially without the use of nepamirstama tillers and small tractors, with the only hope for a spade, Yes a spade. About a year ago, “modelist-Konstruktor” sort of decided to help by posting a good development of the tracer-the potato made from water-gas supply pipes. But then seems to have forgotten the promise to return to the topic of mechanization in the cultivation of labour-intensive crop, which is a pity. V. Ivankov”.
SNEGOKAT FOR SPORT AND RECREATION
In the winter time of the year for motorsports fans there is a period of relative calm. The reason is the bad conditions in which falls the driver, drove on snowy, sometimes icy road on your two-wheeled friend. But on the road you can only travel on a specially prepared (spiked wheels) motorcycle.
POTATOES IN DUTCH
The experience of potato growers says the Dutch technology of cultivation of root crops is the most efficient, and the work is minimal. And rows of clean, smooth, and the harvest excellent. And the basis of all — well organized boarding and, of course, good equipment. I offer readers a short story about the technology and the design of small hand harvester — experienced assistant growers. It can make any novice homebrew.
