Just like the LockCracking robot, this one is a project featured in Wired.com's dependable GadgetLab. The headline brings back fond memories of Blue Peter and its toilet rolls and sticky-back plaster - Scan Old Negatives with a DSLR and Toilet-Paper TubesPhotographer, and Gadget Master, Claus Thiim has described a neat way to scan hundreds of nostalgic negatives and slides.

Thiim's method eschews slow, bulky scanners and doesn't even think about mail-in scanning services. He uses the fastest scanner he has: his DSLR. Onto the front are mounted an old manual focus (90mm) lens, an extension tube (which moves the lens forward and allows closer macro focusing). Then things get creative, with a couple of toilet-paper tubes taped to an old filter with the glass removed, along with a plastic 35mm slide-mount on the end. The mount is opened at the sides to let the film slide through.
To scan, you just move the film through and snap a frame. If your camera has live-view, you can even check framing and focus from the comfort of the rear screen.
