Thanks for the responses. That's more or less what I thought, but it's nice to have confirmation. I thought ColRay's camera looked shorter than I would have expected, so that makes sense. Both cameras on this thread look similar to what I envision, though more elaborate. DWThomas, I'm curious about your tripod mount. That's the part I can't quite figure out (in my mind, I haven't started building yet). Is that a special part (the one with the four flanges)?
