Only a few models of Optoma have upgradeable firmware. Below is a link to a PDF file to explain the procedure for the HD80 model.
You can actually buy a specially made Ipod projector from Optima (their PK-10).It is roughly the same size as an Ipod and when connected it projects a Stand Defintion picture onto the wall.
If you want to trace onto shoes, use the DIY Photo Projector.
as long as the projector is TV compatable nothing
The only real similarity that I can think of is they both project images onto a wall or projector screen.
A projector is a machine that shines a reflection of an image or text onto the surface in front of it. Example: The music teacher shone the song lyrics onto the wall for the children to see via the projector
A projector phone is a phone that can project its screen onto a flat surface, like a film projector. It might be useful as quick and impromptu technological aide for your presentations when there is no access to a proper projector.
An image is formed in an overhead projector by shining light onto a transparent slide or transparency placed on the projector's stage. The light passes through the slide, projecting the image onto a screen or wall. The lens on the projector focuses the light to create a clear and enlarged image for viewers to see.
The projector had a new bulb;we could tell because the image it was "throwing onto the wall" was bright and clear.
A projector is the instrument used to enlarge the image of a film onto a screen. The film is passed through the projector, which then projects the individual frames onto a screen, creating a larger image for audiences to see.
You will need a cable that runs from the PC to the LCD projector. They usually come with the projector. If you turn on the computer, then turn on the projector, then connect the cable, it should automatically detect and appear on the LCD projector. Otherwise, you will have to configure some computer settings to output to the LCD display.
Data can be shown on a large screen by using a projector attached to the computer. The projector throws the image onto either a white sheet attached to the wall, or onto a special projector screen. If, by a very large screen? (as in the question) a serial RS232 9 Pin cable can be attached between the computer and the large monitor/screen.
A condensing lens in a slide projector is a type of optical lens designed to focus and direct light onto the slide being projected. It helps to gather light from the projector's bulb and concentrate it onto the slide, ensuring that the image is bright and well-defined when projected onto a screen. This enhances the overall clarity and quality of the projected image, making it more visually appealing for the audience.
