Need help building a Nice Camera Obscura
many years ago I visited a purpose built CO on the downs above Clifton Suspension bridge nr Bristol (UK) and it projected the outside scene onto a curve table top - this was good because you could easily view the picture the right way up - The mirrors and lens could be rotated so you could vies 360 deg - often though it would be a great addition to my house

Good cutaway of a tabletop unit can be found at https://secure.wikimedia.org/wikipedia/en/wiki/Camera_obscuraWebsearch finds others.Making it bigger permits bigger images.It's up to you to work out appropriate light hoods and decide what your acceptable tradeoff is between image sharpness and brightness.You could, of course, fit it with real lenses rather than just a pinhole lens.
Make it like the originals. Make it out of wood. You can use plywood and make a nice one or you could opt for thin planks. Alittle more work but can be very nice looking.
