12 Nov 1947 rose in the air the Ka-8. This aircraft was the first design of the legendary Soviet designer N. I. Kamov. The helicopter was a simple construction of steel frame and two inflatable cylindrical cylinders. The ka-8 was equipped with an engine capacity of 27 horsepower, which allowed to reach the speed of 80 km/h and weighs about 320 kg For the movement said two coaxial screws with a diameter of 5.6 m, rotating in a different direction.

12 Nov 1952, made its first flight of the legendary turboprop strategic bomber-missile carrier Tu-95. Even today this aircraft is considered one of the fastest turbocharged aircraft of today. It is logical that by 2015, the Tu-95 was subjected to many modifications. The service bombers arrived in April 1956.
In 1949, the design Bureau of Andrei Tupolev designed the first Intercontinental bomber Soviet Tu-85. April 11, 1951 issued a decree of the USSR Council of Ministers for the immediate beginning of the development of a high-speed bomber. On October 31, 1951 was approved drawings of the new project. 20 Sep 1952 first instance of the Tu-95 is unassembled arrived at the airport in the city of Zhukovsky. And on 12 November 1952 the crew of a test pilot A. D. the Flight made its first experimental flight on the prototype.
As you can see, the design and Assembly of the first “carcass” was made as soon as possible. This contributed to the tense situation between the Soviet Union and the United States (read cold war). Unfortunately, not without tragic incidents. So, on may 11, 1953, during the tests on the aircraft as a result of the destruction gear of the third engine caught fire. Before reaching the airport about 40 km, the crew left the aircraft. Unfortunately, 11 people managed to save only seven. Died and the captain ad Flight, tried throughout time to save the bomber. The plane lost a third engine, a corkscrew and crashed into the ground near Noginsk. Was soon assembled second prototype, and in 1956 the serial Tu-95 entered service with the air forces of the Soviet Union.
The aircraft is equipped with four engines NK-12. Each satellite contains two coaxial metal four-bladed propeller AV-60K. The modification of the NK-12MP power at takeoff and about 12,000 horsepower. She is still the most powerful turboprop engine in the world.
Interestingly, 30 Jul 2010 Tu-95 has set a world record for the duration of the non-stop flight among production aircraft for 43 hours bomber flew about 30,000 miles.

12 Nov 2014 successfully launched the project Pi-Top. On the popular kraudfandingovom service IndieGoGo with great success came to an end raising funds to create a series of homemade notebooks. The laptop casing is printed on a 3D printer. The device is a single Board computer Raspberry Pi with three expansion modules, including the controller power bridge HDMI-LVDS controller and the keyboard and trackpad. The composition of the Pi-Top comes with a 13.3-inch LCD panel with a resolution of 1280×720 pixels, battery and a USB Wi-Fi/Bluetooth, and the trackpad and keyboard. In addition to the notebook, each donator received STL files. Therefore, he can independently modify and print the chassis of the laptop according to your taste and mood.
The emergence of a project such as the Pi-Top, demonstrates that the subculture of computer enthusiasts will not go away. On the contrary, it is just growing and growing.
