Watch this video for instructions on how to make your own projector at home!

 

A projector is a device that projects images onto a surface, usually a whiteboard or wall. The objective of the video below is to show you how to make simple projector at home.This YouTube video goes through step by step instructions on what's needed and what needs to be done in order to properly construct an effective DIY projector.The first thing that has to be done is acquiring items such as wood, wire hangers, paint, some type of screen fabric (a bed sheet would work just fine) and reflective material for the lens (aluminum foil will do). The second thing that is needed is a mini video projector which will work nicely. This video goes into detail on what the components of this projector are and how to assemble them using just a few basic tools. The third step involves cutting out the two pieces of wood that will serve as the base for the projector and then screwing the pieces together. Before mounting the wooden base on top of home made screen fabric, screen needs to be painted with a paint that has been already chalked up with white chalk so it doesn't smudge.

The image which is being projected from the projector needs to have a black background. The next step involves putting together a frame which is made of wood and hanging the lens from it. Next, you will need to tape the bottom frame onto the top frame so that they will be perfectly aligned. An under construction look should be given to your underground project so that passersby won't notice it. The last thing that has to be done is placing your screen on top of your projector and the picture should begin projecting itself onto it. At this point, you can start taking in all those funny movies and shows you've always wanted yourself to watch while they are being projected onto a screen projecting them directly into your eyes.

Inputs / Materials Outputs / Products Unit cost ($) Raw material

Cost of production = ? + ? + ?+ ? = $252.07/unit. The unit selling price per unit is $425/(100 units)=$4.25/unit, which is above the desired target selling price of $3.50/unit.

Manufacturing overhead is added at a rate of $3/unit. The new manufacturing cost per unit is $8.25/unit.

Both the target selling price and desired profit are achieved at 100,000 units per year:

Thus, the total profit from sales of 100,000 units is $350,000 (= ($4.25 x 100,000) - $252.07).

A common display resolution for projectors in both business and home use is 1024x600 pixels at 60 Hz interlaced. The price of a projector used in classrooms and office environments ranges from $150 to over $200.

Most projectors have a light source that is not adjustable, and is usually on or near the image plane, which limits the distance of the projection (they cannot be used outdoors). Television sets have adjustment knobs for outputting the appropriate amount of light to illuminate a picture. A projector's light can be restored to its original level by adjusting the bulb's temperature or other effect.
