Multifunctional Multimedia Carts
November 30, 2008Having a projector in your classroom offers all kinds of possibilities for connectivity, including a laptop or desktop computer, interactive whiteboard, interactive tablet, document camera, video player, digital microscope, etc. If you have these peripherals set up on one cart and properly connected, it’s just a matter of knowing what to switch around to use what you need with your projector at any given time.
The first thing that teachers ask about if they are connecting a computer to the projector is the speaker volume. Neither a computer nor a projector provides audio loud enough to be heard throughout a classroom. For that you will need external speakers on your multimedia cart. A number of effective speaker systems by Altec Lansing, Logitech, and Creative Labs (among others) work well with a laptop and are loud enough for a classroom, but check the output power watt of the system. A 3-watt external speaker system will not be much louder than the internal computer speaker. As a rule, a 12-watt speaker system is loud enough for a classroom, but won’t blast through the whole school. It’s hard to find a 12-watt without a subwoofer, but it’s possible. Check the sale flyers for local discount and electronics stores for special deals or shop online. Make sure you check the specifications to be sure it will work with your computer.
Another way teachers are using projectors is to use it in place of a television for playing videos and dvds. Your vcr/dvd can be connected to your projector with a couple of adapters and a composite video/audio cable. You’ll need to purchase the adapters from Radio Shack or another electronics store. The parts you will need are an inline 1/8″ mini-jack coupler (catalog #274-886 @ Radio Shack), a audio Y-adapter (catalog #274-883 @ Radio Shack) and any composite audio/video cable (the one with the red, yellow and white connectors).
To connect your dvd/vcr to your projector, plug the audio cables (red and white) into the Y-adapter and the video (yellow) into the projector. Connect the coupler to the single plug on the Y-adapter and on the open end connect your speaker plug. The other plugs on the composite cable are connected to the dvd/vcr using the color codes for audio and video output. Once you make these connections properly, the projector will project the video from your dvd/vcr and the speakers will play the audio from your dvd/vcr.

Okay, I am originally from Florida so I have to start this one with “Go Gators!”
