Repackaging digital camera in old film camera body.?

I know why ?  Old film cameras are just cooler looking and maybe just the novelty of it to make people wonder.  ( I know it has been done commercially.)  Ok what type of problems will i have with the lens and focusing.  I know I will have to have the shutter stuck open ( or removed)   Will the digital camera part be able to focus after the light passes through the older lens.  What other problems will I need to address reference focusing the digital camera?

I hate to throw stuff away so I scavenge lots of electrical parts, resistors, capacitors, digital displays, etc... I have rarely found a use for any of them which makes me crazy because I guess I'm compulsive. So what we got here anybody know any practical projects? I was going to try to wire up a load of step up transformers in series, and create a stun weapon but hey I again dont have a clue. The displays are so cool that throwing them away is just as crazy. Maybe somebody has a way of turning them into a solar collector or something. I guess thats it, anybody?

Why are my pictures over exposed when taking pictures of running water?

My camera keeps telling me the 'subject is too bright' when trying to take pictures of running water. To get thet 'smokey look' the shutter needs to be left open for say 3 seconds or more but my camera says the subject is too bright consequently the results are over-exposed. Even on a very dull day with ISO at a minimum and a dark filter on my lense. What am I doing wrong?

Hello Instructables. I had a question for my newest project. I am looking to make a Digital taste interface with Arduino like this http://www.nimesha.info/digitaltaste.html#dti.

Does anyone have a better idea as to control current at ranges that low?

digital camera? Answered

I have seen somewhere a cut down digital camera rehoused in a wooden box. the thought strikes me- I have several redundant Olympus lenses could I successfully take a point and shoot digital camera, remove the lens, mount the camera body in a box and add my Olympus lenses to the front to make an exchangeable lens digital camera? I realize I would need to get the lens to CCD distance right but that doesn't seem to be all that difficult - I can engineer an adjustable mount if necessary. it seems a pity to have all these lenses and nothing to do with them. Opinions guys?
