The length of the model car  is the smallest in the world is only 0285 mm, more or less the equivalent of a grain of sand.In order to achieve such a model of formula 1 car it took less than 4 minutes.. It was made ​​up of 100 microscopic layers, each consisting of 200 lines as microscopic.

The process, already well known in the scientific community, called "two-photon lithography." It is a laser beam focused on a liquid resin to make it solid, leaving behind a line of solid polymer great few nanometers. Compared to printing techniques 3d "traditional", the laser can create solid material throughout the liquid material instead of working by adding layer upon layer

It was created by Vienna University of Technology's equipment, in Austria.

It seems there are methods to increase accuracy of the GPS location to cm using a reference station network.

Real Time Kinematic (RTK) satellite navigation  is a technique used in land survey and in hydrographic survey based on the use of carrier phase measurements of the GPS, GLONASS and/or Galileo signals where a single reference station provides the real-time corrections, providing up to centimetre-level accuracy. When referring to GPS in particular, the system is also commonly referred to as Carrier-Phase Enhancement, CPGPS.

"By crossing airships with airplanes, Solar Ship is planning to build a craft that can carry heavy loads long distances with a tiny carbon footprint. Filled with helium, they soak up rays from the sun to provide the energy for forward motion and fulfill its original design challenge – carry 1,000 kilograms (2,205 lbs) of payload 1,000 kilometers (621.4 miles). The craft is heavier than air, and uses a combination of helium filling its interior and its lifting body delta wing shape to stay airborne. Solar Ship shows plans for a range of different size craft for different duties."

Hi,

Tired of cutting your fingers during the testing stage of your quad.

Then make some thin cardboard short propellers.Your fingers will thank you.

What do you think about making a variable pitch quad  with Trex 600 tail rotor assambly parts.

It's using a outrunner motor and a servo for each 70cm blade.

It's also for sale(around 400$)

The Buran spacecraft (Russian: Бура́н, IPA: [bʊˈran], Snowstorm or Blizzard), GRAU index 11F35 K1 is a Russian (Soviet) orbital vehicle (in Russian terminology: "орбитальный самолет", - "orbital airplane") analogous in function to the U.S. Space Shuttle and developed by Chief Designer Gleb Lozino-Lozinsky of Energia rocket corporation. To this day Buran remains the only space shuttle vehicle from the Soviet Buran program that was launched in space before the program closure. The Buran completed one unmanned spaceflight in 1988 before the cancellation of the program in 1993 and was later stored in a hangar at Baykonur cosmodrome before a hangar collapse accident in 2002 destroyed both the hangar and the orbital vehicle. ^[2]

Flight into space
The only orbital launch of Buran occurred at 3:00 UTC on 15 November 1988 from Baikonur Cosmodrome Site 110/37. It was lifted into orbit unmanned by the specially designed Energia rocket, which to this day remains the heaviest rocket running on liquid fuel. Unlike the Space Shuttle, which is propelled by a combination of solid boosters and the Shuttle's own liquid-fuel engines sourcing fuel from a large fuel tank, the Energia-Buran system used only thrust from the rocket's four RD liquid-fuel engines developed by Valentin Glushko. From the very beginning Buran was intended to be used in both fully automatic and manual mode. Although the program accumulated a several-years delay, to this day Buran remains the only space shuttle to ever perform an unmanned flight in fully automatic mode. The automated launch sequence performed as specified, and the Energia rocket lifted the vehicle into a temporary orbit before the orbiter separated as programmed. After boosting itself to a higher orbit and completing two revolutions around the Earth, ODU (engine control system) engines fired automatically to begin the descent into the atmosphere. Exactly 206 minutes into the mission, the Buran orbiter landed, having lost only five of its 38,000 thermal tiles over the course of the flight.[4] The automated landing took place on a runway at Baikonur Cosmodrome where, despite a lateral wind speed of 61.2 kilometres per hour (38.0 mph), it landed only 3 metres (9.8 ft) laterally and 10 metres (33 ft) longitudinally from the target mark.[4] The unmanned flight was the first time that a spacecraft of this size and complexity had been launched, completed maneuvers in orbit, re-entered the atmosphere, and landed under automatic guidance.-

The second Boeing-built X-37B Orbital Test Vehicle, or OTV, left Cape Canaveral, Fla., at 2:46 p.m. PT, atop an Atlas V rocket, Boeing said.
"History was made in December when the X-37B became the United States' first unmanned vehicle to return from space and land on its own," Craig Cooning, vice president and general manager of Boeing Space and Intelligence Systems, said in a statement today. "The success of that mission validated this reusable and effective way to test new technologies in space and return them for examination."

Boeing on Monday unveiled a potential new eye in the sky, this one powered by hydrogen fuel.

The Phantom Eye, an unmanned aerial vehicle from the company's Phantom Works division, is expected to make its first flight early next year. Boeing is pitching the demonstrator UAV as a "first of its kind" aircraft that "could open up a whole new market in collecting data and communications."

A decade into the 21st century, surveillance drones are nothing new considering the now long-running successes of aircraft such as the Predator and the Global Hawk. What sets the Phantom Eye apart is the hydrogen propulsion system. Although hydrogen has been bandied about for some time as an alternative energy source, it has yet to progress much beyond the novelty stage.
