Still reading? Great! Let's start building. OVERHEAD PROJECTOR FULL
The hardest part of this build was the software, because I couldn't find one that would fulfill my expectations: - FREE - NO BANNER - WinXP x32 / Win7 圆4 / Win8 compatible - digital zoom compatibility - full screen mode - save picture - portable (no installer) So I had to write my own software, (don't worry, I'll give it to you, for free) Edit 1: The source code for my software is available on GitHub. USB cameras are now quite cheap (my " Canyon CNR-WCAM820HD" was around 30€) so why not just build your overhead/document camera ? Actually the build part is super simple, even more if you use for the base an old overhead projector, which makes this camera even better, because you can light the object underneath and possibly make some internal structures of the object visible. But unfortunately they aren't so cheap! Alternative to them is a old school Opaque projector, overhead projector and but they are becoming rare, saving the projection to digital format is annoying (take a photo), and also the lamp generates quite a mount of heat. Document camera or also called overhead camera, is a great tool to have in class, to better display some small 3D objects or documents.
