While traditional film cameras can be constructed from little more than a light-tight container, a pinhole, and a piece of light-sensitive paper, replicating a digital camera out of everyday household objects presents a far greater engineering and optical challenge. Yet, this is precisely the kind of inventive puzzle that architecture student and viral content creator Nikita Merkushin loves to solve. In a recent project that has captured the attention of photography enthusiasts and tech fans across social media, Merkushin successfully built an oversized, fully functioning digital instant camera using a combination of cardboard, a magnifying glass, a mirror, and an ordinary office flatbed scanner.
Known online by his handle @noizebro, Merkushin shared a viral video detailing the unconventional build, offering viewers not only an entertaining look at DIY engineering but also a surprisingly educational refresher on the fundamental mechanics of how all cameras capture images. At its core, every camera relies on a simple premise: a lens gathers and focuses light, projecting an optical image onto a light-sensitive surface or digital sensor. Merkushin’s oversized contraption took this basic optical physics lesson and scaled it up into a whimsical, working prototype.
To create the lens assembly, Merkushin utilized a simple magnifying glass, demonstrating the foundational physics of optics by first using the glass alone to project a crisp, inverted image onto a piece of paper. From there, he constructed a custom housing out of cardboard, carefully shaping it to fit directly over the top of a standard printer-scanner combination unit. He mounted the magnifying glass securely at the front of this cardboard shell, serving as the camera’s primary optic.
Solving the geometry of the device required a clever workaround. Because the lens was positioned perpendicular to the flatbed scanner bed rather than parallel to it, Merkushin had to direct the incoming light downward. He achieved this by angling the rear interior of the cardboard housing and mounting a mirror inside it. This mirror successfully intercepted the image projected by the magnifying glass and reflected it downward onto the glass surface of the scanner bed, bridging the gap between traditional optics and digital scanning technology.
Once fully assembled, Merkushin took his bulky, handmade creation out into the real world for a test run. Operating the device involved capturing scenes by utilizing the scanner’s digital capabilities to transfer the resulting image files directly to his mobile phone. Furthermore, because he utilized an all-in-one printer-scanner model, the setup allowed him to bypass a purely digital workflow and print out physical, instant photographs right on the spot.
While the resulting device is undeniably oversized, awkward to handle, and entirely impractical for everyday street photography or casual snapshots, the experiment serves as a brilliant physical demonstration of core photographic concepts. It vividly illustrates how a lens projects light onto a sensor to form an image, translating abstract optical theory into a tangible, moving spectacle.
Beyond its educational value regarding lenses and sensors, the quirky camera also offers a fascinating real-world demonstration of how digital shutters operate. Unlike a standard camera sensor that captures an entire scene simultaneously or rapidly reads out pixels in fractions of a second, the flatbed scanner mechanism operates by slowly moving a light bar down the length of the document bed. Because the scanning process takes time rather than happening instantaneously, any movement occurring within the frame during the scan becomes noticeably distorted.
This mechanical limitation mirrors the behavior of a rolling shutter found in many modern digital cameras and smartphones. While a camera’s electronic rolling shutter functions at vastly higher speeds than a mechanical office scanner—allowing most subjects to be captured without obvious warping—extremely fast-moving subjects can still suffer from a characteristic distortion known as the "jello effect." In contrast, high-end global shutters expose the entire sensor simultaneously, avoiding this kind of motion skew entirely. Merkushin’s scanner camera takes this rolling shutter phenomenon to an extreme, exaggerated degree, providing a visual explanation for a technical concept that many photographers encounter in digital imaging specifications.
Merkushin is no stranger to going viral with inventive, DIY engineering projects that intersect with photography and visual media. The resourceful architecture student previously constructed a unique film camera mounted on top of a bicycle helmet, designed to automatically capture a photograph every time his jaw dropped open, triggered by a simple pull string. His broader portfolio of creative experiments frequently explores the boundaries of optics and spatial projection. In another widely shared video, he utilized a bike-mounted projector system to cast the illusion of a running horse galloping dynamically down public city streets.
For those inspired by the experiment but seeking something a bit more portable than a cardboard box strapped to a printer, the market offers various commercial alternatives. Photographers fascinated by the charm of instant results combined with digital convenience can turn to hybrid digital instant cameras and specialized instant printers. These modern consumer devices pack the spirit of instant photography into pocket-sized form factors, sparing enthusiasts from having to lug a flatbed scanner and a magnifying glass down the street.
