Overhead Projectors

Archive for the ‘Used Overhead Projector’ Category

I don’t know want to use them on Overhead Projectors. I need it to change the color of light for a science project. I need blue, green, and red. Purple is okay too instead of blue.

I know there’s a Michaels and AC Moore where I live. There’s Office Depot and Staples, as well. Help?

Hi,

When I was in college circa 2001, my college lecture hall used a Overhead Projector (OHP). But that OHP was not the normal type of OHP that uses a transparent paper (a.k.a. transparency). The normal OHP has a yellow or white lamp situated inside the ‘body’. And you would place the transparency above that ‘body’ and the light from the lamp would project through the transparency and unto mirrors and then onto the screen.

The OHP I want to find does NOT use transparency, in fact, it can project unto a screen anything within it’s view. i.e. objects, or paper.

For instance, you just need to put a paper under the view, then the OHP will reflect that image unto the screen. So you just need to write on that piece of paper and voila, the item is up there on the screen. You can obviously be able to adjust the focus and etc. If i remember correctly, there is no ‘body’ on the OHP, just a flat surface where you put the object/paper and a white flourescent or somekinda white lamp and with the mirrors and such.

My lecturer used it instead of transparencies because it was easier and convenient and cheaper. because u dont need to print it on transparencies. I want to buy this OHP for my work now but I dont know what it the name to search for it.

Please if you could tell me the name or where I can buy it, I’d appreciate it a lot. I dont need an integrated projector for laptops, computers, etc. Just a simple OHP that I am looking for. Thanks.

That was called an "opaque projector." They were handy. You can probably still find these at art stores or online.

Is there a simple (and cheap!) way to make an Overhead Projector for showing some transparency images on my wall? I figure all I’d really need is a light box underneath with a mirror and lens over it to project the image. Were could I find a lens to use (if this method would even work of course)? Would this produce clear images or would it be fuzzy?

those projectors had special lens on base, and the upper part had two lens’s. along with super brite projector lens.
I am willing to bet there are a lot of schools that have a storage room full of them.
