When you’re above a definite age, you most likely consider the ambience of a pre-Powerpoint 35 mm slide display. The wobbly display being unrolled, the darkened room, the cushy hum of the projector’s fan, the moderately grainy image at the display and that unmistakable click-whoosh-clack sound because the projector loaded the following slide. This present day you’ll be onerous pressed to search out somebody prepared to arrange a display and darken the room simply to observe a couple of pictures, so in the event you nonetheless have any slides mendacity round you’ll most likely wish to digitize them. When you’ve additionally saved your projector then this doesn’t even should be that tricky, as [Scott Lawrence] presentations in his newest mission.
[Scott] made a setup to without delay attach a DLSR, on this case a Nikon D70, to a Kodak 760 slide carousel. The attachment is made via a 3D-printed adapter that matches onto the Nikon’s macro lens on one aspect and slides snugly into the carousel’s lens slot at the different. The adapter additionally holds an IR transmitter which is aimed on the digicam’s receiver, with the intention to cause its far flung shutter free up serve as.
The carousel’s unique gentle supply used to be changed with a compact LED studio gentle, which permits for actual brightness keep an eye on and naturally stays great and funky in comparison to the unique incandescent bulb. The sunshine, digicam and carousel motor are all managed via a central person interface pushed by way of an Arduino Leonardo which will mechanically advance the carousel and instruct the digicam to take an image, thereby taking the onerous determine of digitizing massive stacks of slides.
[Scott] plans to make the tool and STL recordsdata to be had on GitHub quickly, so somebody can pass forward and switch their projector right into a digitizer. When you’ve out of place your projector alternatively, a easy 3D-printed slide adapter to your digicam additionally works for small slide decks.
