Alternative to Document Cameras

How many of you have a digital camera or have access to a digital camera that came with a RCA cord that you have never even pulled out of the box?  You know... that cord with one small mini jack on one end and 3 different colors (white, yellow, red) or one yellow RCA connection on the other end.

Do these cords look familiar?
These cords are usually found on all digital cameras, allowing you to not only connect the camera to a digital screen, but also an LCD projector. Doing so allows you to produce the captured images on a larger-than-life scale.

What you will need:
1. Digital camera with video output
2. LCD projector with video input - input directly on machine or on wall connection for ceiling mounts
3. Cable to connect the two (1/8" mini jack to RCA - see pictures)
4. Lots of batteries or a well charged battery for the digital camera. Even better... use an AC adaptor if you have you have one.
Connecting directly to a projector:

Connecting to a ceiling mount projector - use wall connection:

Power on the digital camera and the LCD projector. Press the "Menu" option on the projector or using the remote, then choose "Input." Select either the "Video" input. The digital camera's contents will appear on the screen.  You can use the zoom in/out features to display zoom in or out on objects such as butterfly wings.

Instantly share/project pictures taken with digital camera to an entire class or large group.  Connect the camera to the projector or TV. Turn on the camera. Select "video" for input on projector or TV. Press the play mode and pictures on the camera will display on the screen. No need to huddle together to squint and look at images on the small camera display. Pictures can be displayed on TVs or project your pictures on large screens for everyone to enjoy!

Ideas for using document cameras in the classroom

  1. Brilliant!
    And using the Macro Mode (tulip icon setting) on most cameras, you can get a sharp focus really close up to objects almost like a low power microscope.
    But if you want to be really adventurous you can try pointing the camera down the eyepiece of the microscope. If you have steady hands you can even get a decent picture.
