Since I’m moving in a few months to an apartment of significantly reduced size, I am starting to reduce the size of my collection of stuff. One thing I’ve been carrying around is everything from my college career. I have every syllabus, paper, homework assignment, handout, midterm… in total it was three boxes full of binders. This represents tens of thousands of dollars of education, though, and I wasn’t entirely willing to part with it. I started scanning pages with a scanner. I had a process that was giving me up to 6 scans per minute. The quality of the scans was good, but the speed was not fast enough, and there were too many manual parts to the process. I needed something faster.
I realized that a photo of a piece of paper would be faster than having a scanner do it, and if lit well enough and with a good enough lens, it would be just as good as a scanner. I rigged up a tripod with an extended arm to hold my camera, and I put a white background on the desk and marked some lines where the paper needed to be to be in the shot. Since I don’t have a fancy DSLR with a remote, and pressing the button manually was way too much effort and moved the camera around too much, I rigged up a piece of twine so that by pulling down on the twine I could get the camera to take a shot. I tried pulling the string for a while, which was pretty fast, but still not as efficient as possible. I tied the twine to a ruler and used the ruler as a foot pedal, giving me both hands to move the pieces of paper as quickly as possible. The light sources were just regular white compact fluorescent bulbs, placed to put as much light on the paper as evenly as possible.
The resulting contraption bumped my speed up to 15 pages per minute on average. Sometimes it was higher depending on if I was dealing with loose notes or stapled sheets. Having the shutter controlled by my feet gave me a huge advantage, and I was able to fly through all 3 boxes of papers in a few evenings much faster than I expected. Now I have it all on my computer, which should probably still be sorted, but at least it’s not taking up any physical space, and I don’t have to feel any sense of loss when I recycle my stacks of papers.
