Well... a PINHOLE camera, that is!
Some leftover oak, a piece of 0.003" brass sheet stock, and some scraps of laminate to make the "springs".
Let's see, if my calculations are correct...
The film holders are from ebay: $5 for three of them. The trickiest part was making the back so it holds the film holder securely but changes out easily. The other "unknown" is whether I got the focal length correct -- I won't really know until I take some pictures. I've never made anything like this before so I'm sort of winging it! I started with 6", but if I don't like that I can always "adjust" it (on the tablesaw!).
I have a friend who has some darkroom equipment, and my film just arrived today, so hopefully I'll have some pics to show soon! (I know, I know... "no pics, didn't happen!" :lol: )
