Open Source Computer Controlled Loom Weaves Pikachu For You

The origin story of software takes us back past punch card computers and Babbage’s Difference Engine to a French weaver called Joseph Marie Jacquard. Jacquard created a way to automate mechanical looms, giving weavers the ability to change a loom’s pattern by simply switching punch cards. This invention not only made it possible to produce detailed fabrics in a vastly simplified way, it was an extremely important conceptual step in the development of computer programming, influencing Babbage’s development of the Analytical Engine amongst many other things.

So, when [Kurt] saw his son’s enthusiasm for weaving on a simple loom, he started thinking about how he could pay homage to the roots of software by designing and building an open source computer controlled loom. He knew this was going to be difficult: looms are complex machines with hundreds of small parts. [Kurt] wrestled with wonky carriage movements, cam jams, hook size disasters and plenty of magic smoke from motor control boards. After a year and a half of loom hacking he succeeded in making a 60 thread computer controlled loom, driven by an iPhone app using Bluetooth.

As well as writing up the story of this build on his blog, linked above, [Kurt] has also has made all of his design files, PCB layouts, firmware and code available on GitLab.

We’ve featured a few weaving hacks over the years, including this cheap, simple 3D printable loom and a Jacquard inspired bitmap display.

Fun, informative build video after the cut.

The E-Waste Apocalypse Looms

What does post-apocalyptic technology look like? Well, that kind of depends on the apocalypse. Regardless of the cause, we’ll need to be clever and resourceful and re-learn ancient crafts like weaving and pottery-making. After all, the only real apocalyptic constants are the needs of the survivors. Humans need clothing and other textiles. Fortunately, weaving doesn’t require electricity—just simple mechanics, patience, and craftsmanship.

If it turns out the apocalypse is scheduled for tomorrow, we’ll have piles and piles of e-waste as fodder for new-old looms. This adorable loom is a mashup of old and new technologies that [Kati Hyyppä] built at an artist residency in Latvia, a country with a rich historical tapestry of textile-making. It combines a cheerful orange telephone with an old cassette player and some telescoping rods from a radio antenna. [Kati] reused the phone’s hang-up switch to trigger tunes from a deconstructed toddler toy every time the receiver is lifted. Check it out after the beep break.

And yeah, you’re right, it does use batteries. But the looming part doesn’t require power, only the music. In case of apocalypse, just scrounge up a solar panel.

If you’d rather be prepared to have to make your own clothes someday, print this loom beforehand.

Poetry Is The Fruit Of This Loom

We’d wager that most people reading these words have never used a loom before. Nor have most of you churned butter, or ridden in a horse-drawn wagon. Despite these things being state of the art technology at one point, today the average person is only dimly aware of their existence. In the developed world, life has moved on. We don’t make our own clothes or grow our own crops. We consume, but the where and how of production has become nebulous to us.

[David Heisserer] and his wife [Danielle Everine], believe this modern separation between consumption and production is a mistake. How can we appreciate where our clothing comes from, much less the people who make it, without understanding the domestic labor that was once required to produce even a simple garment? In an effort to educate the public on textile production in a fun and meaningful way, they’ve created a poetry printing loom called Meme Weaver.

The Meme Weaver will be cranking out words of woolen wisdom at the Northern Spark Festival taking place June 15th and 16th in downtown Minneapolis. If any Hackaday readers in the area get a chance to check out the machine, we’d love to hear about it in the comments. Take photos! Just don’t blame us if you have a sudden urge to make all of your clothing afterwards.

Make A Bit Of Cloth With This 3D Printable Loom

When the hackspace where this is being written created their textile room, a member who had previously been known only for her other work unexpectedly revealed herself to be a weaver, and offered the loan of a table-top loom. When set up, it provided an introduction to the art of weaving for the members of all different interests and backgrounds, and many of them have been found laying down a few lines of weft. It’s a simple yet compelling piece of making which  captivates even people who might never have considered themselves interested in textiles.

If you are not lucky enough to have a friendly hackspace member with a spare loom when you wish to try your hand at weaving, you may be interested in this Thingiverse project, a 3D printable rigid heddle loom. It’s not the most complex of looms, the heddle is the part that lifts the warp threads up and down, and it being the rigid variety means that this loom can’t do some of the really fancy tricks you’ll see on other types of loom. But it’s a functional loom that will allow you to try your hand at weaving for the expenditure of not a lot of money, some 3D printer filament, and some PVC pipe. If your hackspace or bench has an area devoted to textiles, it may find a place.

We’ve shown you a few looms on these pages over the years, but mostly of the more mechanised variety. A Raspberry Pi automated loom for example, or a CNC Jacquard loom.

3D Printing With Yarn And Silicone

This one is apparently a few years old, but the idea looks so good that we’re left wondering whatever happened to it.

[Seyi Sosanya] made what amounts to a 3D printer, but one that prints in a unique way: wrapping yarn around pillars and then post-dipping them in a silicone glue. The result is a tough, flexible 3D mesh that’s lightweight and looks fairly resilient. We’re not at all sure what it’s good for, but watching the video about the project (embedded below) makes us want to try our hand at this sort of thing.

So what happened? Where did this project go? Is anyone else working on a glue-plus-fabric style printer? Is anyone doing this with carbon fiber and epoxy? We can also imagine that with the right adhesive this could be used less like a loom and more like a traditional FDM machine, although weaving the layers together may provide additional strength in what would be the Z direction, and for that you’d need the supports.

One Man, A Raspberry Pi, And A Formerly Hand Powered Loom

[Fred Hoefler] was challenged to finally do something with that Raspberry Pi he wouldn’t keep quiet about. So he built a machine assist loom for the hand weaver. Many older weavers simply can’t enjoy their art anymore due to the physical strain caused by the repetitive task. Since he had a Pi looking for a purpose, he also had his project.

His biggest requirement was cost. There are lots of assistive looms on the market, but the starting price for those is around ten thousand dollars. So he set the rule that nothing on the device would cost more than the mentioned single board computer. This resulted in a BOM cost for the conversion that came in well under two hundred dollars. Not bad!

The motive parts are simple cheap 12V geared motors off Amazon. He powered them using his own motor driver circuits. They get their commands from the Pi, running Python. To control the loom one can either type in commands into the shell or use the keyboard. There are also some manual switches on the loom itself.

In the end [Fred] met his design goal, and has further convinced his friends that the words Raspberry Pi are somehow involved with trouble.

Computer-Designed Portraits, Knit By Hand!

Artist [Petros Vrellis] has done something that we’ve never seen before: his piece “A New Way to Knit” lives up to its name. What he’s done is to take the traditional circular loom, some black thread, and toss some computing at it. And then he loops the string around and around and around.

The end result of following the computer’s instructions is a greyscale portrait. Where few black strings overlap, it’s light, and where more overlap, it’s darker. That’s the whole gimmick, but the effect is awesome. As you zoom in and out, it goes from a recognizable face to a tangle of wires and back. Check out his video embedded below.
