DIY Help (camera lucida)

This one may be out of left field. My instructor has required us to build a camera lucida before the end of the term. She refuses to give us any instruction, saying that if you can find instructions to build a bomb on the internet, you can probably find this too.

So far the only site I've found that clearly shows how to build one is here, and despite the picture of the guy sitting there using it, I can't see how it's supposed to work. Don't these things usually incorporate a mirror or prism somehow? I have no idea, and the end of the term is creeping up on me.

Has anyone ever built one of these, or know how they might be built with common household/hardware store materials? I think there might be bonus points if you can figure out how to build one to attach to a microscope, but all things considered I'm not feeling too ambitious.

And it seems like all is dying, and would leave the world to mourn

    The wikipedia page seems to give a reasonable description of how it works, and the first two external links have photos and tips.

    But maybe you tried this already? The wikipedia page is the first thing that comes up in Google. From what I can tell, you can just clamp a prism at the correct angle so that when you look in it it looks like your subject is already on the paper.

    The link you provided is more helpful if you click on the image gallery link, and then go to the second image:
    http://www.motherearthnews.com/multimedia/image-gallery.aspx?id=68018&seq=1. Also the second page describes how to actually use it. If you have access to lab equipment, it looks just like a standard lab clamp and holder.

    Yeah, I did see both those pages. The confusion isn't with what the instrument is supposed to do, but with how those instructions will get me the same result without a mirror or prism. Or the hope that perhaps someone can find better instructions than I was able to. :/

    Did you see the second page of the link you posted, and the second image in the gallery? They seem detailed enough. It uses plexiglass instead of a mirror or prism.
