MICROCAR FDD
I was born in 1944, and almost from the first year of life I was haunted by a sound — an ominous growl bearings rolling on asphalt. The sound that accompanied the movement on a small wooden carts returned from the war disabled legless…
And at that time was a lot — according to current estimates, over three million. The majority of former fighters of order-bearers disappeared in the vast expanses of our country, but many settled in cities, including the capital of our country. And their only vehicle was at the time knocked together from planks truck with ball bearings, equipped with a pair of rough, reminiscent of the iron wood, which the disabled, starting from the road, causing her to move…
RECOVERY SYSTEM — “ROTOR”
Only four of the class includes one of the most “fresh” categories of model rockets — on the duration of the flight with the rotor — S9. The competition in this category will start only single-stage models, which utilize the principle of autorotation of the main rotor as the only way to “soft” landing on the ground. Autorotation should occur only along the longitudinal axis of the model and result in the erection and operation of the rotor.

SENSITIVE METAL DETECTOR
I have designed the metal detector works on the principle of beating is generated due to the difference of the oscillation model and tunable oscillators (5-10-th harmonic, selects the nearest frequency). This allows to increase the sensitivity of the instrument to the point that it becomes possible to detect, say, a five-kopeck coin in the soil at 10 cm, and a steel manhole or pipe — to 65-cm depth. Performed on the available element base, a metal detector does not require careful tuning and maintenance. Power supply — galvanic battery “Crown”.
THE SOUND CONFIRMS THE COMMAND
Simple circuits sound LEDs turn on electronic devices
In Amateur practice, it is frequently necessary to announce the inclusion of any homemade or industrially produced household electronic appliance, equipment or device — which is unusual, pleasant to the ear (if picked up a soft tone audible signal). This is especially true when the appliances operated with a remote control — an acknowledgement signal confirms that the received command. For example, when the operation control of air conditioning — when it is turned on or the mode is changed as a response to user, sound short and melodious sound signal duration of 1 — 2 seconds.
WHAT IS THE AXE BETTER?
Ax with a straight blade is used successfully in meat cutting, but for chopping wood it is not suitable: there are much more efficient is the blade of the carpenter type, with a rounded sharp edge. It is better enters the wood easily separates the chips. Therefore, the axe of a carpenter blade must be rounded 250 — 270 mm.
TRACTOR KIROVETS-700A
Farm tractor Kirovets K-700A. Scale model 1:32.
The purpose tractors – agricultural works with mounted, semi-mounted and trailed machines and transport, some excavation and reclamation work in agriculture.
July 13, 1962 from the Assembly shop of the Kirov factory has released the first tractor K – 700 “Kirovets”. Leningrad, now St. Petersburg, the plant was not randomly selected for the development and production of the most powerful and today the farm tractor. The oldest Russian enterprise in 1924 was able to start production of tractors “Fordson-Putilovets”.
THE TRICK
You still keep fur hats, wigs and hats on the shelf of the Cabinet? Meanwhile, the creators of these hats is strongly recommended to keep them worn on special mannequins — thus things do not crumple and keep the form longer.
The easiest and quite functional dummy is obtained from a five-liter plastic bottles from under drinking water — you only need to fasten a screw threaded cap from the bottle on a wooden stand, and then screw the neck of the bottle into the cover.
MULTI-STOREY HANGERS
To save space in the closet and to facilitate the selection of clothes will serve as a multi-storey racking. It can be made from a sheet of thick plywood, Plexiglas or any other plate.
