A white, house-shaped clock with the words "TEMPUS NECTIT" written in faux Roman script in black on a strip of silver at the base of the "roof." a white power cord extends from the left of the enclosure, and the center of the clock is a 22 pin knitting machine wheel with one pin covered in silver metalic. A white plastic peg extends from the bottom right of the enclosure to hold the feedstock yarn.

Tempus Nectit, A DIY Knitting Clock With Instructions

April 5, 2023 by Navarre Bartz 1 Comment

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.

Knitting Clock Makes You A Scarf For Next Year

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.

Interesting Substrate Used To Position LEDs Of This Word Clock

March 6, 2012 by Mike Szczys 5 Comments

[Ivan] decided to build a Word Clock as holiday gift for his parents. He pulled it off, but as you can see above, it meant a lot of point-to-point soldering. One small piece of proto-board is used to host the power supply and a few integrated circuits, with the rest of the device mounted on an interesting choice of material.

The substrate that holds the LED array for the display is a plastic mesh. You’ll find the stuff in any craft store, it’s meant for use in yarn work. It comes rated in several different sizes designated by holes-per-linear-inch. This is fantastic because it makes precision spacing a snap. The face plate itself looks great, especially when you consider that all of the letters were cut out from a piece of black foam board by hand. This bezel was then put in a picture frame, with a bit of tissue paper as a diffuser.

They tell us that the code was written in assembly for an ATtiny2313 microcontroller. It uses a DS1305 RTC chip to keep time and you might be interested to see how the communication protocol was implemented in assembly. The project is based on [Doug’s] Word Clock which we covered in this links post.
