We’re no strangers to unusual clocks here at Hackaday, and some of our favorites make time a little more tangible like [Kyle Rankin]’s knitting clock.
Inspired by our coverage of [Siren Elise Wilhelmsen]’s knitting clock, [Rankin] decided to build one of his own. Since details on the build from the original artist were sparse, he had to reverse engineer how the device worked. He identified that a knitting clock is essentially a knitting machine with a stepper motor replacing the hand crank.
Using a Raspberry Pi with an Adafruit motor hat connected to a stepper motor and a 3D printed motor adapter, [Rankin] was able to drive the knitting machine to do a complete round of knitting every twelve hours. By marking one of the knitting pegs as an hour hand, the clock works as a traditional clock in addition to its year-long knitting task. [Rankin] says he still has some fine tuning to work on, but that he’s happy to have had the chance to combine so many of his interests into a single project.

While you could 3D print a lampshade, there’s something to be said for having a more active role in the process of creating an object. [THINKK Studio] has made custom lampshades as easy as riding a bike.
The Lanna Factory was inspired by the cotton ball string lamps sold by vendors in Thai flea markets. Bangkok-based [THINKK Studio] wanted to build a device to let anyone have a hand (and feet) in making a custom lampshade without any experience. Five spools of thread are routed through a “glue case” and onto a spindle holding a lampshade mold. Pedals control the wrapping speed and the location on the shade being wrapped is controlled with a hand wheel on the table.
Once the glue dries, the shade can be removed from the mold and fitted with the appropriate hardware. Giving the user control over the process means that each lampshade will be unique and the final product will mean that much more to the person who made it.
If you’re thinking this would be cooler in carbon fiber, than maybe you should checkout the X-Winder.

Time got a little wibbly wobbly during these pandemic years. Perhaps we would’ve had a more tangible connection to it if [Siren Elise Wilhelmsen]’s knitting clock had been in our living rooms.
Over the course of a year, [Wilhelmsen]’s clock can stitch a two meter scarf by performing a stitch every half hour. She says, “Time is an ever forward-moving force and I wanted to make a clock based on times true nature, more than the numbers we have attached to it.” Making the invisible visible isn’t always an easy feat, but seeing a clock grow a scarf is reminiscent of cartoon characters growing a beard to organically communicate the passage of time.
We’d love some more details about the knitting machine itself, but that seems like it wasn’t the focus of the project. A very small run of these along with a couple prototypes were built, with a knitting grandfather clock now occupying the lobby of The Thief hotel in Oslo.

What’s just a bit thicker than a human hair and has ten times the capability of a human muscle? Polymer-coated carbon nanotube yarn. Researchers at the University of Texas at Dallas created this yarn using carbon nanotubes coated with a polymer and coiled with a diameter of about 140 microns.
Passing a voltage through the fiber causes the muscle yarn to expand or contract. Previous similar fibers have to do both actions. That is, they expand and then contract in a bipolar movement. The polymer coating allows for unipolar fibers, critical to using the fibers as artificial muscles.

Making a natural fiber like wool into something useful like a sweater involves a lot of steps. We might be familiar with shearing the sheep, spinning the wool into yarn, or knitting and weaving, but between shearing and spinning there’s another unfamiliar process you’ll have to go through. Known as carding, it helps align the fibers so they are able to be spun, and of course it requires either an expensive tool, or one you build on your own.
This drum carder is exactly what it sounds like. It uses two drums covered in a metal mesh, spinning at different speeds, which pull the fibers into an orderly shape. Small drum carders like this can run around $600 but with some quality wood and a lathe you can easily make one for a fraction. Making the series of drums is fairly straightforward with a lathe, and from there you need to make sure they are connected with a quality belt or chain and then covered in the appropriate metal mesh.
[kris] notes in the reddit comments section that he’d like for a second version to spin a little faster and be a little more durable, but this is a great working carder nonetheless. From there you’ll want to move on to spinning the wool into yarn, which you can do with either a wheel or an electric motor.

We’re all used to posing for a picture — or a selfie — but there’s something about photo booths that make getting your photo taken an exciting and urgent affair. To make this experience a bit easier to tote about, Redditor [pedro_g_s] has laboriously built, from the ground up, a mobile photo booth named Buzz.
He needed a touchscreen, a Raspberry Pi, almost definitely a webcam, and a 3D printer to make a case — although any medium you choose will do — to build this ‘booth.’ That said, he’s built the app in a way that a touchscreen isn’t necessary, but carting around a mouse to connect to and operate your portable photo booth seems a bit beside the point. On the back end, he used Electron to code the photo booth app, React helped him build a touchscreen UI, and Yarn kept the necessary dependencies in order.
Operation is simple, and every time a photo is taken it is sent to and collated within a previously set-up email service. To set it up, [pedro_g_s] is here to guide you through the process.

As much as we love crazy prototype style hacks, we really enjoy seeing things that get used after their creation. [Marcus] sent us the information about his automatic yarn winder. Noticing that his friends who knit had to go through the monotonous process of winding a ball of yarn each time they started the process, he sprung into action. After finding only a few commercial solutions, which were out of his price range, he decided to build his own. He found a hand cranked version and gutted it to add a motor. Now, they simply need to get it started and walk away. Great job [Marcus].
