Public service for all illiteratefags, quoting from the site linked in OP:
Solargraphs are easy to take. All you need is an empty drinks can, some photographic paper and lots of gaffer tape. Put the photographic paper into a drink can camera, cover the lid to keep out the elements, find a position pointing towards the Sun, and fix the camera well. At the end of the exposure period, place shutter tape onto the hole. Find a dark room with a computer. Scan in a 5x7" piece of blank paper (so the scanner knows the area to scan). Now, without developing it, scan the photo paper on a high resolution. Save the negative image on your computer. You'll need to invert and flip the image horizontally.
