If you wanted an expensive camera when you were a kid, you’re in luck. Used film SLRs are super cheap now that everyone wants digital cameras. Of course, in reality, you also want a digital camera. So do what [befinitiv] did. Make a film cartridge from a Raspberry Pi that can convert your camera to digital. (Video, embedded below.)
In theory, this sounds like a genius idea. The practical aspect is however not perfect. For one, the small image sensor used means the camera is quite zoomed in. Also, the shutter button is not integrated, so the shutter is open all the time. You might think it doesn’t matter, but remember that the way a DSLR works means that if the shutter is open, there’s no viewfinder.
Still, the packaging is neat and we wondered if it might entice someone to go a little further. You can find the design files in OnShape.
It seems clear you really need a larger image sensor, although we suspect you could mount a wide-angle lens or an adapter to help some. You can also put optics inside the camera, but that would cause more packaging problems. We also don’t know if the resulting image would be better or worse than what you got on a film negative.
We think of digital cameras as relatively new technology, but they have quite a history. Or hack a camera for full spectrum.
