Thacker) Organization: AT&T Bell Laboratories Lines: 18 Approved: military@att.att.com From: Michael Edelman As mentioned, many of the CCDs used in camcorders and other consumer products have excellent infrared sensitivity. One that's cheap and easy to modify is the Fisher-Price kiddy camcorder, often sold for less than $100. If you open up said camcorder and unscrew the lens assembly you'll notice a small square filter; this is an IR blocking filter. Prying it off makes the camera tremendously IR sensitive, although you've more-or-less trashed the daytime usefulness. It's reverseable, though. I've seen the same module used in the Fisher-Price in other products, such as the Lionel Trains camera. --mike edelman muppet labs medelma@cms.cc.wayne.edu medelma@waynest1
