CANOEING LIKE THE INDIANS
“A canoe made of birch bark… the most convenient and easy means of transportation. The bark of one birch, typically enough for one canoe; they are in a suitable form that float on water easily, like a cork” (John. Catlin, 1841).
Boat of the North American Indians can be fairly easily made not only of birch bark, but of a hard, fibrous plates (e.g. hardboard) or thin plywood. Below is a guide to the manufacture canoes from such sheets.
COUNTRY TURNTABLES
Favorite home gardeners have always been turntables rattles, driven in rotation by the wind — they are designed to repel moles and other rodents that can damage the roots of the garden trees and shrubs. The most popular is the vane attached in front of the propeller. However, there are equally effective and at the same time more simple “burner”, who do not need the device, rotate the propeller into the wind.
OLD BIKE – NEW WALK-BEHIND
During design development we present motoblock tried to solve three tasks. First, maximum use of to manufacture standing for several years without case motorcycle “Minsk”. Secondly, to be able to make at home, with minimal turning and without using expensive parts. Finally, third, we wanted to make a walk-behind tractor, which would be a good mechanical helper in the household with a plot of land: that it was earth to plow, potatoes and other root vegetables to plant, inter-row cultivation of plants run, and the harvest be removed and relocated.
The tillers turned out pretty good, it met expectations and tested to work in severe conditions.
CATAMARAN MATTRESSES
For lovers of hikes of the day off prefer to relax on the water, great interest will present an unusual variant of the lightweight catamaran, published in the Hungarian magazine “Earmaster”. This is a single pleasure “boat” with a rowing treadle, which is based on two beach inflatable mattress They are used without modification or any improvement, therefore retain its traditional meaning. And to go on them in a small swimming — perhaps fishing or just a ride — enough to lay a small wooden frame with attached to it a conventional folding chair, popular with vacationers and retirees.
SUN PROTECTION
If the solar rays fall on the thermometer, mounted outside window frame, it heats up and shows… its temperature, not the ambient air.
MUFFLER – ASSEMBLY DIFFICULT
Interest in homemade silencers due primarily to the poor quality of serial products. It is quite natural Amateur designer to improve their technique. Of course, significantly improve engine power due to the muffler at a given noise level of the exhaust gases is almost impossible, but to eliminate some of the shortcomings of industrial designs is still quite real.
SOVIET LIGHT TANK T-30
SOVIET LIGHT TANK T-30. Scale model 1:25.
Floating tank T-40 serially produced in the USSR since 1940 and was intended to replace the T-37A and T-38. As its predecessors, its design was widely used by the automobile units and mechanisms. The engine and transmission were located at the right side, so the tower with the DShK and DT was shifted to the left side. The tank hull was made of rolled armor plates connected by rivets and welding. The undercarriage of the vehicle consisted of four rubber-tions of rollers on Board with individual torsion bar suspension. For the movement in the water in the lower part of the stern of the hull was installed in a niche of the couple-trehlopastnye screw and two vodorodnoe the helm. By June 1941 the Red Army had 220 tanks T-40. However, the first fights showed the lack of weapons this tank, as it mostly used as reconnaissance and for direct support of infantry. As floating it has almost never been used.
LIGHT CONTROLS THE DOOR
Device for automatically switching-off the lights in the bathroom (dressing) room are designed to seamlessly allow the following situations:
1. In the served room is unoccupied, the door is closed or locked from the outside, the light is not lit.
2. Still in the bathroom (the toilet) no one. However, the door is open and lights are on. This situation occurs when the mean in the bathroom (toilet) for something: for example, a rag or a bucket or to execute the cleaning.
3. Inside behind a locked door is a man and the light in this room must be turned on (lit lamp ЕL1).
GAZEBO IN THE GARDEN
In a quiet corner of the garden of his manor house planted Douglas fir. Three years have passed. The tree grew, grew. And then came the idea to build a small gazebo that over time, the fir in a hot summer day will cover the shadow of its branches. At leisure even made a sketch of the structure. But, as is often the case, the embodiment of the idea was hampered by lack of materials, but rather the allocation of the family budget for their purchase, as the case was not so urgent. But the idea to give is not wanted. Began to ponder how to carry out the construction, so it was not expensive, but beautiful: the house — building rather for the soul, and finding it should be fun.
