This NTNU project uses neurofeedback to control an RC-helicopter. By analyzing the signals from electrodes attached to the head, it is possible to control the elevation of the helicopter. This is controlled by software connected to an RC-transmitter via a USB-interface. With extended use, it is possible to train the brain to create certain types of brain waves. The training is made more interesting by moving a physical object instead of auditory or graphical feedback. The neurofeedback training is applicable for a number of uses, but mainly focusing on attention ability.

Flying remote control helicopters is really an amazing experience that everyone want to achieve. These toy helicopters are operated through a hand-held device known as transmitter from a distance. These flying objects has gained world recognition within a very short span of time and alluring the attention of people of all ages.

Radio controlled helicopters are real fun devices to have. A perfect hobby for those who love flying. With all the modern software’s and gadgets today it’s become even easier to start flying your radio controlled helicopter. First of all you need to get a simulator that teaches you how to fly your radio controlled helicopter. This is a windows based program and can be plugged into the USB ports with an interlinked transmitter.

Its better you learn using this program before you get a model of your own .It helps you reduce or rather avoid any crashes. The next thing you have to do after you are sure of your flying abilities is getting yourself a helicopter. You have two basic categories to choose from – Nitro or an electric. For beginners a nitro model will do because it’s larger and much easier to work with as compared to an Electric model.

With a nitro Model you can choose from sizes 30, 40, 50, 70, 90. To start with you can go with a low budget 30 size.  Another low budget models that you can use to start off with are Compass Model or Esky, this model is very easy to use, easily available at any hobby store and you can practice in your very own living room.  After you have gained a little experience you can buy the Compass Model Knight 50 Sport, the most durable models in the market.

Once you got the model that you wan the next step is to get all the equipment that you need which is a must to fly your radio controlled helicopter. These equipments include your servos, gyros, transmitters, tail blades, main blades, paddles and field equipments. Your transmitter has to have at least six channels. You can try the new Spread Spectrum available from companies like Futaba. This works on 24 GHz and it does not interfere with any other radio systems, so you don’t have to worry about any interference. This transmitter will cost you around 0 to 0, but it’s definitely worth an investment because you can use this for a lifetime. Next coming to your servos.

Servos are actually devices that convert the electrical signals into mechanical actions. The servo that you get depends on the type of model you have. Generally all models require four servos, one to control the tail rotor pitch and three to control the swash plate. You will need three similar servos for the swash plates and a high speed one for the tail rotor. A gyro is necessary to control the tail rotor. You can get both the servos and the gyros for around 0.Anothe device needed is the blades which are usually available in the kit, but if they are not you can choose from wooden, fiberglass and carbon fiber blades. Next you will need your field equipment which includes the glow igniter, starter wand and motor and a fuel pump. All these items are sold in a kit and can be purchased easily depending again on your model.

Owning a radio controlled helicopter can be a lot of fun but learning how to fly one takes a lot of patience and hard work. It’s a skill game.

Radio Controlled Helicopters Rotorfest 2008 Brandywine Airport West Chester, Pennsylvania Sunday October 12, 2008 IN THIS VIDEO, watch as a scale model of a NOTAR helicopter and two electric radio controlled models take to the skies over Brandywine Airport. Take note of how maneuverable the last two helicopters are - you will NEVER see a real helicopter perform those kinds of maneuvers! Like what you've seen? Well, if you are interested in purchasing DVDs of specific aircraft and/or of airshows, interested in anything and everything related to airshows (where the jet teams will show up, all airshow performers, airshow reports from airshows I have attended, previews of airshows I will be attending, etc.), a much more easier to navigate "version" of all of my videos, and/or everything there is related to aviation - including spotting guides to my favorite airports and military bases and aircraft factfiles, please take time to check out Steve's Airshow World at www.stevesairshow.com .

(PRWEB) October 5, 2002

SALT LAKE CITY - October 3, 2002 - parvus Corporation today announced that its PC/104 1553/Ethernet Interface board is shipping. This Commercial-Off-The Shelf (COTS) PC/104 form factor module is designed to bring both MIL-STD-1553B protocol and NE2000-Plus Ethernet compatibility to an embedded avionics computer system. The board operates over an extended operating temperature range of -40º C to +85º C and is competitively priced at $ 1,575/each in volume orders of 100 or more.

Measuring only 3.550" x 3.775" in size, the 1553/Ethernet Interface (Part Number: PRV-0950X-01) utilizes Aeroflex UTMC's SµMMIT MIL-STD-1553 support chip to operate as a data Bus Controller (BC), Remote Terminal (RT), or Bus Monitor (BM) for a variety of 1553 military avionics and ground vehicle applications. Four 16-bit register locations allow complete access to interface functions through PC/104 I/O space, while test routines enable access to memory and internal registers. The support chip also allows interrupts to be generated and routed to the PC/104 bus.

The Ethernet portion of the board is fully NE2000 and NE2000-Plus compatible and based on the popular National Semiconductor AT/Lantic AT DP83905 chip, taking advantage of this chipset's proven reliability and the maturity of drivers available in most operating systems. The standard version of the board includes a 4-pin, low-profile Molex connector for 10BaseT connections, enabling a standard RJ-45 jack to be cabled out for panel-mounting in a faceplate, endcap, housing, or bulkhead.

APPLICATIONS

The PC/104 1553/Ethernet Interface is specifically designed to work with transformer-coupled stubs in military Local Area Network (LAN) applications, including airplanes and helicopters, as well as space and land-based systems. 1553 technology is commonly used to process data for navigation and attitude,
