Quote At the risk of dating myself, I feel compelled to say that when I was a kid, I did all the things budding geeks were supposed to do. For example, I made a crystal radio (a simple radio that doesn't need a battery) and a pinhole camera. A pinhole camera is perhaps the simplest kind of photographic device, because it uses no lens. A tiny pinhole in a well-sealed cardboard box is all you need to capture an image on film. http://tech.msn.com/guides/articlepcw.aspx?cp-documentid=4967284>1=10240 |
