DIY camera

Thought this interesting, but perhaps not a subject for APUG -

When I was a child my parents gave me a toy that was basically DIY optics projects. It included a telescope, binoculars, and a 35mm camera with telephoto lens. It was all plastic that snapped together. Unfortunately, I never successfully assembled the camera - but it did help me learn.

There are very nice sets for analogue plastic cameras, like:
"DIY Recesky Twin Lens Reflex TLR Camera Assembly Set".
They can be found on Ebay for about $15.
Real fun and better than a Lomo.

And that new(-ish) Konstruktor 35mm SLR.
