Comment on Using the railway network as a flatbed scanner

Comments

Ward Cunningham and I did something similar back in 2008.

We were both at a startup in Portland and our office was along the railroad tracks east of the Willamette. We were up on the 4th or 5th floor right above a lot of train traffic including Amtrak.

I brought in some extra Mac gear I had including one of the early iSight cameras which back then was an external device you stuck on the top of your display and connected to the Mac via FireWire. We set it up and rolled the desk over to the window in the office and turned the camera around pointing down at the tracks and Ward got to work hacking something up to do a slit scan.

It was a fun little project; the speed of the trains affected the horizontal compression of the images. We could tweak the software to expand or contract the size of the image by adjusting the number of slit scans per unit of time. Of course, that affected the exposure but I recall the camera having some automatic adjustments that gave us trouble.

That's about all we did with it. Just a quick afternoon hacking project. Neither of us thought much about it at the time so we didn't save anything.

A few years ago I took a photo out the window of a Shinkansen going 150 mph and was amused that everything in the foreground tilted significantly to the left because of this effect. This is about as close as I'll get to seeing what it's like to get sucked into a black hole.

That sounds more like rolling shutter effect: https://en.wikipedia.org/wiki/Rolling_shutter
