Back Up Your Data On Paper With Lots Of QR Codes

1 Share

QR codes are used just about everywhere now, for checking into venues, ordering food, or just plain old advertising. But what about data storage? It’s hardly efficient, but if you want to store your files in a ridiculous paper format—there’s a way to do that, too!

QR-Backup was developed by [za3k], and is currently available as a command-line Linux tool only. It takes a file or files, and turns them into a “paper backup”—a black-and white PDF file full of QR codes that’s ready to print. That’s legitimately the whole deal—you run the code, generate the PDF, then print the file. That piece of paper is now your backup. Naturally, qr-backup works in reverse, too. You can use a scanner or webcam to recover your files from the printed page.

Currently, it achieves a storage density of 3KB/page, and [za3k] says backups of text in the single-digit megabyte range are “practical.” You can alternatively print smaller, denser codes for up to 130 KB/page.

Is it something you’ll ever likely need? No. Is it super neat and kind of funny? Yes, very much so.

We’ve seen some other neat uses for QR codes before, too—like this printer that turns digital menus into paper ones. If you’ve got your own nifty uses for these attractive squares, let us know!

Over-molding Wires with Hot Glue and 3D Printed Molds

1 Share

We’ve said it before and we’ll say it again: water always finds a way in. That’s particularly problematic for things like wire splices in damp environments, something that no amount of electrical tape is going to help. Heat shrink tubing might be your friend here, but for an electrically isolated and mechanically supported repair, you may want to give over-molding with a hot glue gun a try.

The inspiration for [Print Practical]’s foray into over-molding came from a video that’s making the rounds showing a commercially available tool for protecting spliced wires in the automotive repair trade. It consists of a machined aluminum mold that the spliced wires fit into and a more-or-less stock hot glue gun, which fills the mold with melted plastic. [Print Practical] thought it just might be possible to 3D print custom molds at home and do it himself.

His first attempt didn’t go so well. As it turns out, hot glue likes to stick to things — who knew? — including the PETG mold he designed. Trying to pry apart the mold after injection was a chore, and even once he got inside it was clear the glue much preferred to stay in the mold. Round two went much better — same wire, same mold, but now with a thin layer of vegetable oil to act as a release agent. That worked like a charm, with the over-mold standing up to a saltwater bath with no signs of leaking. [Print Practical] also repaired an iPhone cable that has seen better days, providing much-needed mechanical support for a badly frayed section.

This looks like a fantastic idea to file away for the future, and one that’s worth experimenting with. Other filament types might make a mold better able to stand up to the hot glue, and materials other than the ethylene-vinyl acetate copolymer found in most hot glue sticks might be explored. TPU over-molds, anyone? Or perhaps you can use a printer as an injector rather than the glue gun.

Immense Biomorphic Sculptures Snake from Floor to Ceiling at Hamburger Bahnhof in Eva Fàbregas’ ‘Devouring Lovers’

Bulbous, biomorphic sculptures in lavender, tangerine, and blush pink rove throughout the airy Hamburger Bahnhof in Berlin. The largest solo exhibition to date of Barcelona-born artist Eva Fàbregas, Devouring Lovers brings massive, bulging works to the industrial hall, juxtaposing the cold iron structures with soft, pudgy forms. Inviting in color and grotesque in shape, the organic, monstrous sculptures appear alive, as if they could grow and swallow up the remaining space, viewers and all.

In a recent interview, Fàbregas shares that the interactions between space and the body continually inform her thinking and how she conceptualizes a piece. “It’s about the architecture. It’s about those masses that you put inside the architecture. It’s about the humans moving around the architecture,” she says. “For me, my sculptures are not just themselves, it’s all the things that happen in the same space that affect that installation.”

Devouring Lovers is on view through January 14, 2024. You can find more from Fàbregas on Instagram.

Page Through a 19th-Century Embossed U.S. Atlas Designed with Touchable Cartography for Blind Students

About a decade after French educator Louis Braille invented the eponymous system for blind and sight-impaired readers, the New England Institution for Education of the Blind released its own embossed designs allowing those with low or no vision access to important information. Under the leadership of Samuel Gridley Howe, the school, which is now the Perkins School for the Blind, acquired a printing press in 1835 and began to create a variety of learning materials with raised writing for its students. One of those books was an atlas of the United States, which held touchable cartography within its pages.

Paired with descriptions written in standard Latin script—this proved much more difficult to read than braille and never gained the popularity of its counterpart—the maps contain typical information like longitude and latitude, along with the area’s population, climate, and commerce. Solid lines denote rivers, a singular raised shoreline buttressed by parallel lines represents oceans, and clustered triangles are mountains. Printed in 1837 in an edition of 50, this version of the atlas contains just 24 states. Only four copies are known to remain.
