Draper 136033 Salara Plug and Play Projection Screen NTSC – High Contrast Grey (84 Inches)

Draper 136033 Salara Plug and Play Projection Screen NTSC - High Contrast Grey (84 Inches)

  • The Draper 136033 Salara Plug and Play Projection Screen is a new generation in motorized projection screens. In your home or office, the Salara makes a design statement. The Salara’s small, elliptical case and domed endcaps are finished in solid white. The Projection Screen mounts to the wall or ceiling with “floating” gunlatch mounting brackets which can be positioned along the back of the case. The mounting brackets make installation quick, easy, secure, and barely visible.

    There is no wiring required with the Plug and Play Screen because you can just plug it into a standard 110V wall outlet and you are ready to go. The included IR Remote allows for convenient remote control from anywhere you can view the screen. An IR Receiver is hidden in the case of the screen.

    When selecting a front projection surface, several factors need to be considered:

    • Gain – a relative measure of a screen’s reflectivity.
    • Contrast – the ability to accurately reproduce and differentiate light and dark characters and backgrounds, or light and dark areas of an image.
    • Ambient light rejection properties – the ability to perform well under normal to adverse audience lighting conditions.
    • Resolution – the clarity of the projected image.
    • Uniformity – the screen’s performance when viewed from various points off the projection axis (both horizontally and vertically), and when the brightness of the center of the image is compared to the corners.
    • Aspect ratio – the screen’s height and width configuration, formatted for the desired projection source (NTSC video, HDTV, WideScreen, CinemaScope, overhead, slide or motion pictures).
    • Textile Backed Screen Surfaces – These surfaces consist of a reflective surface laminated to a woven textile base. The screen surface hangs suitably flat because of the stability of the material and the weight of the bottom dowel. Good for all types of projection. Commonly used for single lens video projection, as well as for CRT video and data-graphics projection.
    • Matt White – The standard to which all other screen surfaces are compared. Matt white vinyl reflective surface laminated to tear-resistant woven textile base. A matt white surface diffuses projected light in all directions, so the image can be seen from any angle. Provides accurate color rendition as well as superior clarity. Recommended for use with all high light output projection devices. Requires control of ambient light in the audience area. Washable, flame and mildew resistant. Peak gain 1.0.
    • Glass Beaded – Brighter on-axis viewing than matt white surfaces within a narrower viewing cone. Some loss of clarity. Not for use with ceiling or floor mounted projectors. Flame and mildew resistant, but cannot be cleaned. Now available seamless in all standard sizes through 10′ high.
    • High Contrast Grey – Grey textile backed surface offers excellent resolution while enhancing the blacks of LCD and DLP projected images, even as whites and lighter colors are maintained. Performs well in ambient light condition. High Contrast Grey’s lower gain of 0.8 allows use with even the brightest projectors; viewing cone of 180&deg. Available on most non-tensioned motorized and manual screens, seamless in sizes up to 8′ in height. Peak gain of 0.8.
    • AT Grey – AT Grey offers the acoustical properties of our popular AT1200, while providing the best optical qualities of both Matt White and High Contrast Grey. It is unique in that it offers both a 180Β° viewing cone and the vivid color contrast associated with high contrast grey materials. Washable, flame and mildew resistant. Available in sizes through 6′ x 8′ or 10′ diagonal. Gain of 0.8. Not recommended for screens smaller than 80″ wide when used with LCD or DLP projectors. Peak gain of 0.8.
    • AT1200 – Innovative and versatile acoustically transparent screen material. Similar in gain performance to standard matt white. Acoustical properties comparable to the finest speaker grille cloth. Peak gain of 1.0.
    • Tensioned Surfaces – These screen surfaces are tensioned vinyl with no backing. Draper offers motorized, crank-operated and permanently tensioned screens with built-in tensioning systems. The advantage: the surface is stretched perfectly flat, resulting in better picture quality. Flatness is always desirable and highly recommended for video or data-graphics projection.
    • Rear Cineflex – Neutral grey rear projection diffusing surface with an on-axis gain of 1.3. Cineflex has high resolution and excellent contrast, even in lighted rooms. For use with any type of projection equipment.
    • Flexible Matt White -Pliable matt white material for use in our Cinefold portable folding screen. It can be stretched, folded and restretched repeatedly without damage. Flexible matt white is an excellent matt white material with a gain of 1.0 and a viewing cone of 180&deg.
    • HiDef Grey – A grey front projection surface that provides greater contrast and black reproduction than standard surfaces, with a lower gain to handle today’s super-bright projectors. The grey color enhances color contrast and black levels in the projected image and also allows for more ambient light in the audience area than traditional surfaces. Available on all tab-tensioned and permanently tensioned screens. Peak gain of 0.9.
    • M1300 – The perfect matt white diffusing surface. Extremely broad light dispersion and spectral uniformity. Panoramic viewing angle and true color rendition. Recommended for use with any type of projector in rooms where the light level can be reasonably controlled. Washable
    • M2500 – Higher gain surface provides good black retention with accurate light colors and whites. M2500 is black-backed, and tolerates a higher ambient light level in the audience area than many front projection screen surfaces. On-axis gain of 1.5.
    • Black-Backed M1300 – Our M1300 viewing surface with a black backing for situations where ambient light behind the screen is an issue. Peak gain of 1.0.
    • Low-Gain Cineflex – New Low Gain Cineflex surface offers a wider viewing cone and added contrast level with a neutral grey tint. This is ideal in applications where ambient light is needed, yet you want to limit your hot spot. This should be considered when you have a bright projector and rigid screens are not an option. Some ideal installs may include churches, training centers, or other large venue need. To order 0.8 Low Gain Cineflex just add LG to the end of any part number for a screen with standard Cineflex viewing surface.
    • Uniflex White – Uniflex Flexible Rear Projection Surface or Front Projection Surface. Draper’s Uniflex surface is ideal for wide angle viewing including edge blending or multiple projection applications. This product virtually eliminates hot spots in either front or rear applications and is ideal to use with short throw lenses. Light control is suggested with this product. Rear projection .7 gain/Front projection .5 gain. To order Uniflex just add UW to the end of any part number for a screen with Cineflex viewing surface.
    • Aspect Ratio
    • AV (1:1) – AV (audio visual) format screens accommodate a variety of projector types and range from square to wide horizontal in aspect ratio. AV format screens are described in terms of height x width, and are furnished without black borders.
    • NTSC (4:3) – NTSC video format screens are specifically designed for use with video/data projectors. Their format is strictly defined as a 4:3 rectangle, and the size is usually described in terms of a nominal diagonal. Conventional models of NTSC format screens are furnished with black borders to frame the image on all four sides.
    • HDTV format (16:9) – HDTV format is designed for high-definition television projection.
    • WideScreen format (1.85:1) – WideScreen format is suitable for letter boxed video images.
    • CinemaScope (2.35:1.00) – Cinemascope is the sizing of many Hollywood feature films and is wider than Letterbox Format or HDTV Format. Film projectors achieve this aspect ratio by replacing the typical standard ‘Flat’ lens with an anamorphic ‘Scope’ lens.
    • Native laptop presentations (16:10 and 15:9) – Accommodates presentations from laptop computers and projectors with 1280×800 resolution.

WindyNation WGN-CWTK-75 WindTura 750 Complete Wind Turbine Kit

WindyNation WGN-CWTK-75 WindTura 750 Complete Wind Turbine Kit

  • The WGN-CWTK-75 WindTura 750 Complete Wind Turbine Kit from Windy Nation allows its user to capture the kinetic energy of the wind to generate electricity. The WindTura 750 is capable of producing 800 Watts of power in 29mph wind speeds and as much as 1100 Watts of power in 35mph wind speeds. This generated electricity can be used for applications such as to feed a grid tie inverter, off grid power or to charge 12 Volt or 24 Volt battery banks. The electricity is captured by three, 35 inch blades which use the kinetic energy of the wind to rotate its 3 phase AC permanent magnet alternator. Electrical power is produced by the rotation of the permanent magnet alternator and is then transferred by 3 electrical wires to ground level.

    To protect itself from damage and failure in high wind conditions the WindTura 750 uses a method referred to as furling. The assembled tail is attached to the yaw mount which is on a 20 degree angled pivot bar. This pivot bar is what allows the yaw mount and generator to rotate away from the wind as speeds gust over 30mph. Once wind speeds exceed roughly 30mph the generator and blades will begin to rotate out of the wind as a result of the rotational inertia of the spinning blades. As wind speed continues to increase the generator and blades will continue to rotate out of the wind until they reach nearly 90 degrees to ensure they are protected. When the wind speed returns to a speed of 30mph or lower the generator and blades will begin to unfurl and face the wind directly again to ensure optimum performance. Without this rotation away from the wind the turbines generator would begin rotating at such high rpms that the current (amps) produced would be too much heat for the generator to handle causing it to overheat and breakdown. To ensure that the furling mechanism works correctly it is important to make sure the tower is installed vertically and it is recommended that a level be used to confirm this. If the WindTura is not mounted vertically then the generator and blades can begin to furl at undesignated wind speeds. For optimum performance it is recommended that the turbine be mounted 20 feet above all nearby objects.

    Please Note:Your Windy Nation WindTura 750 Wind Turbine is designed with your personal safety as the first priority. However, there are still some inherent dangers involved with any electrical and/or mechanical equipment. Safety must be the primary concern as you plan the location, installation and operation of the turbine.

    For detailed installation instructions please refer to the owner’s manual in the overview section and/or the installation videos. Make sure to review installation warnings before installation to ensure a safe setup.
