I picked up one of these today via FreeCycle, with 5 packs of film. As best I can tell the film is unusable. I took a few shots today and they’re really yellow and nasty looking.
The camera itself works fine. I’m fascinated by Polaroids. The technology in the film is one thing, but the cameras are always interesting. This one is one of the newer ones where the batteries are in the film pack, not the camera. So the battery is as fresh as the film. Neat idea. In this case, the batteries have outlasted the film.
And the focusing? Rather than some fancy phase-detection system, this thing uses a sonar to determine the distance to the subject. From there, I’m not sure what it does, but here’s how to get at it if you want to repurpose it. I don’t hear anything moving around, like a lens.
This would be quite useful for a lot of things, like repelling animals (varying the intensity of a water cannon based on the distance), parking vehicles in tight spaces, maybe put one on a commuter bike to flash a light when cars get too close.
I see 600-type cameras in thrift stores all the time: I may have to add one of those to the accumulation of cruft.
I wonder how you could make a home-brew instant image system? How would you record a latent image and how would you then make it visible? Hmmmm . . .
