Digitize Your Slide Deck With This Arduino-Powered Slide Carousel

If you are previously mentioned a particular age, you in all probability keep in mind the ambiance of a pre-Powerpoint 35 mm slide clearly show. The wobbly display screen being unrolled, the darkened place, the delicate hum of the projector’s admirer, the a bit grainy photo on the monitor and that unmistakable click-whoosh-clack seem as the projector loaded the following slide. Nowadays you will be really hard pressed to come across any one inclined to set up a display screen and darken the room just to look at a couple of pictures, so if you continue to have any slides lying close to you’ll almost certainly want to digitize them. If you have also held your projector then this does not even have to be that hard, as [Scott Lawrence] exhibits in his most recent undertaking.

[Scott] manufactured a setup to immediately link a DLSR, in this circumstance a Nikon D70, to a Kodak 760 slide carousel. The attachment is built by way of a 3D-printed adapter that matches onto the Nikon’s macro lens on 1 facet and slides snugly into the carousel’s lens slot on the other. The adapter also holds an IR transmitter which is aimed at the camera’s receiver, in buy to result in its distant shutter launch function.

The carousel’s primary gentle supply was replaced with a compact LED studio mild, which allows for precise brightness manage and of course continues to be wonderful and awesome when compared to the primary incandescent bulb. The gentle, digital camera and carousel motor are all controlled through a central consumer interface driven by an Arduino Leonardo which can instantly progress the carousel and instruct the digital camera to choose a photo, thus using the challenging do the job out of digitizing big stacks of slides.

[Scott] plans to make the computer software and STL files readily available on GitHub shortly, so everyone can go ahead and change their projector into a digitizer. If you have misplaced your projector however, a basic 3D-printed slide adapter for your digital camera also is effective for smaller slide decks.
