Awhile ago I threw out an old Hitachi rear projection tv. Didn't know about all this stuff at the time.
Is there any good stuff in those that can be used? Diodes, lenses, etc?

Depends what type. If its really old you'll have a large PBS cube. If its a DLP it will have a small PBS cube, and diodes, but not the type we use. They can be used, but as far as I know no one has made a build with them yet. In all cases there is a huge first surface mirror. Plus misc electronic parts, and do dads.
