GeekTechnique wrote an interesting article on how you can turn your digital camera into an infrared camera. Detail and informative. If you have an old unused digital camera, why don’t you try the tutorial?

First of all, I know this has been done before (with webcams for example), but I thought it would be nice to give you an extensive insight view of how I transferred my old digital camera (which would probably fetch only $30 on ebay or such) into a infrared camera. The whole idea is just that a lot of people probably have old cameras laying around, collecting dust, so why not make one of your old cameras an infrared one?
