Movies are more and more Stirring into the familiar. Confident, film theatres are useful. However with Netflix, video-on-demand, Hulu and Blu-Ray, the competence To possess an exceptional cinematic training is no longer confined to a darkened space abundant of general public moulding elsewhere, texting and talking. The biggest bar to most homely theatres is the prohibitive expenditure. So why not generate a projector? Building your own projector can save you a parcel of income and build surprisingly high-quality results.
Instructions
1. Obtain a used overhead projector. These hefty beasts can recurrently be purchased used from faculty districts or other polity surplus avenues. The most leading naked truth is the wattage of the light-bulb. While 250 watts Testament chore, seek away a 400 watt bulb. The brighter the bulb, the larger. The glass surface field of your overhead projector should be slightly larger than the LCD watchdog you intend to capitalization.
2. Remove the LCD from the scanner enclosure. The LCD itself is bare fragile, so lay the monitor face down on a towel or other soft surface while removing the nonessential components.3. Strip the LCD monitor of the back-light components. The circuit boards affixed directly to the monitor are vital, but much of the material backing the LCD is unnecessary for the final projector. This the most bad component of the procedure, so employment last caution. Popular LCD personal computer monitors own a screwed-on enclosure. Remove the screws and receipts off the plastic backing.
As a general rule, do not remove circuit boards attached directly to the LCD's edge. The back-light will be a separate set of components that must be gently removed. Once the LCD is free it will look like a clear panel with circuitry, including the power connection, attached to the side.
4. Being careful not to scratch the screen, place the LCD on top of the overhead projector. Include spacers, such as washers or wood blocks, on the four corners to raise the LCD at least 2 inches above the glass surface of the projector.
5. Connect the LCD and fire it up. Testing the LCD at this point is important in order to ensure that all the necessary circuitry components have been included. Turn the monitor off quickly, as it remains prone to overheating.
6. Tape the UV filter between the overhead projector glass and the LCD. This will protect the LCD from light damage over time.
7. Attach a fan to the surface of the overhead projector. Without constant airflow, heat will build up very fast against the surface of your LCD. If this happens, the screen will quickly brown and become disabled. A simple component board fan, available at any electronics store, can provide the necessary airflow. Affix the fan with electrical tape to the side where air can most easily flow into the space between the projector and LCD.
8. Build an enclosure. An enclosure for your new projector can protect your components from dust, pets and accidental bumps. It can be made of wood, cardboard or metal. Make sure to include plenty of ventilation.
