Quilting Desk Is An Absolute Unit

August 1, 2019 by Kristina Panos 10 Comments

Most hobbies come with a lot of tools, and thread injecting is no different. Quilting itself may be Queen Hobby when it comes to the sheer volume of things you can buy: specialized templates, clips, thimbles, disappearing ink pens, and so on. And of course, you want it all within arm’s reach while sitting at the machine.

Years ago, [KevsWoodworks] built an impressive custom quilting desk for his wife. He’d added on to it over the years, but it was time for a bigger one. This beautiful beast has 21 drawers and 6 large cubbyholes for plastic bins. At the wife’s request, one of the drawers is vertical. [Kev] doesn’t say what she put in there, but if it were our desk, that’s where we’d stash all our large plastic rulers that need to be kept flat (or vertical). There’s also a lift, so any sewing machine can be brought up flush with the enormous top.

Fortunately for us, [Kev] likes to teach. He documented the build in a series of videos that go nicely with his CAD drawings, which are available for download. Thread your way past the break to see those videos.

Want to do some thread injecting, but don’t want to spend hundreds on a machine? We got lucky with our entry-level injector. If yours is a piece of scrap or has limited stitch options, replace the motor, or add an Arduino.

CNC Embroidery Machine Punches Out Designs A Stitch At A Time

November 17, 2018 by Dan Maloney 19 Comments

It’s doubtful that the early pioneers of CNC would have been able to imagine the range of the applications the technology would be used for. Once limited to cutting metal, CNC machines can now lance through materials using lasers and high-pressure jets of water, squirt molten plastic to build up 3D objects, and apparently even use needle and thread to create embroidered designs.

It may not seem like a typical CNC application, but [James Kolme]’s CNC embroidery machine sure looks familiar. Sitting in front of one of the prettiest sewing machines we’ve ever seen is a fairly typical X-Y gantry system. The stepper-controlled gantry moves an embroidery hoop under the needle of the sewing machine, which is actually the Z-axis of the machine. With the material properly positioned, a NEMA 23 stepper attached to the sewing machine through a sprocket and drive chain makes a stitch, slowly building up a design. Translating an embroidery pattern to G-code is done through Inkstitch, and extension to Inkscape. [James]’ write-up is great, and the video below shows it in action.

We’ve seen a CNC embroidery machine or two before, but our conspicuously non-embroidered hat is off to [James] on this one for its build quality and documentation. And the embroidered Jolly Wrencher doesn’t hurt either.

Stretching My Skills: How (and Why) I Made My Own Compression Sleeves

May 28, 2018 by Kristina Panos 70 Comments

Have you ever noticed how “one size fits all” often means “one size poorly fits all”? This became especially clear to me when I started using a compression sleeve on my arm. Like any hacker, this seemed like something I could fix, so I gave it a shot. Boy, did I learn a lot in the process.

A little over a year ago, I started dropping things. If I was holding something in my left hand, chances were good that it would suddenly be on the ground. This phenomenon was soon accompanied by pain and numbness, particularly after banging on a keyboard all day.

At best, my pinky and ring fingers were tired all the time and felt half dead. At worst, pain radiated from my armpit all the way to my fingertips. It felt like my arm had been electrocuted. Long story short, I saw a neurologist or two, and several co-pays later I had a diagnosis: cubital tunnel syndrome.

Bumblebee Breakout, A DIY Wearable Connector

March 18, 2018 by Lara Grant 16 Comments

The practice of developing wearable electronics offers a lot of opportunity for new connector designs and techniques for embedding electronics. Questions like these will eventually come up: How will this PCB attach to that conductive fabric circuit reliably? What’s the best way to transition from wire to this woven conductive trim? What’s the best way to integrate this light element into this garment while still maintaining flexibility?

Mika Satomi and Hannah-Perner Wilson of Kobakant are innovators in this arena and inspire many with their prolific documentation while they ask themselves questions similar to these. Their work is always geared towards accessibility and the ability to recreate what they have designed. Their most recent documented connector is one they call the Bumblebee Breakout. It connects an SMD addressable RGB LED, such as Adafruit’s Neopixel, to a piece of side glow fiber optic 1.5mm in diameter. On a short piece of tubing, the four pads of the SMD LED are broken out into four copper rings giving it the look of a striped bumblebee. To keep from shorts occurring while wrapping the copper tape contacts around the tube, they use Kapton tape to isolate each layer as they go.

This connector was originally created to be used in a commission they did out of Koba, their e-textile tailor shop located in Berlin. Fiber optics were applied to jackets for a performance called “All Your Base Are Belong To Us” produced by the Puppetry Department of the Hochschule für Schauspielkunst Ernst Busch.

Peruse more e-textiles techniques and learn how to build a connector transitioning from an embroidered thread bus to a wire and how to knit solderable circuit boards. And make sure to click around Kobakant’s website, it’s full of e-textile DIY tutorials!

Vintage Sewing Machine To Computerized Embroidery Machine

February 21, 2018 by Brian McEvoy 19 Comments

It is February of 2018. Do you remember what you were doing in December of 2012? If you’re [juppiter], you were starting your CNC Embroidery Machine which would not be completed for more than half of a decade. Results speak for themselves, but this may be the last time we see a first-generation Raspberry Pi without calling it retro.

The heart of the build is a vintage Borletti sewing machine, and if you like machinery porn, you’re going to enjoy the video after the break. The brains of the machine are an Arduino UNO filled with GRBL goodness and the Pi which is running CherryPy. For muscles, there are three Postep25 stepper drivers and corresponding NEMA 17 stepper motors.

The first two axes are for an X-Y table responsible for moving the fabric through the machine. The third axis is the flywheel. The rigidity of the fabric frame comes from its brass construction which may have been soldered at the kitchen table and supervised by a big orange cat. A rigid frame is the first ingredient in reliable results, but belt tension can’t be understated. His belt tensioning trick may not be new to you, but it was new to some of us. Italian translation may be necessary.

The skills brought together for this build were vast. There was structural soldering, part machining, a microcontroller, and motion control. The first time we heard from [juppiter] was December 2012, and it was the result of a Portable CNC Mill which likely had some influence on this creation. Between then, he also shared his quarter-gobbling arcade cabinet with us.

The Textile Bench

May 23, 2017 by Jenny List 52 Comments

What’s on your bench? Mine’s mostly filled with electronic test equipment, soldering kit, and computers. I’m an electronic engineer by trade when I’m not writing for Hackaday, so that’s hardly surprising. Perhaps yours is like mine, or maybe you’ve added a 3D printer to the mix, a bunch of woodworking tools, or maybe power tools.

So that’s my bench. But is it my only bench? On the other side of the room from the electronics bench is a sturdy folding dining table that houses the tools and supplies of my other bench. I’m probably not alone in having more than one bench for different activities, indeed like many of you I also have a messy bench elsewhere for dismantling parts of 1960s cars, or making clay ovens.

My textile bench, with a selection of the equipment used on it.

The other bench in question though is not for messy work, in fact the diametric opposite. This is my textile bench, and it houses the various sewing machines and other equipment that allow me to tackle all sorts of projects involving fabric. On it I’ve made, modified, and repaired all sorts of clothing, I’ve made not-very-successful kites, passable sandals, and adventurous tent designs among countless other projects.

Some of you might wonder why my textile bench is Hackaday fodder, after all it’s probably safe to assume that few readers have ever considered fabricating their own taffeta ball gown. But to concentrate only on one aspect of textile work misses the point, because the potential is there for so much cross-over between these different threads of the maker world. So I’m going to take you through my textile bench and introduce you to its main tools. With luck this will demystify some of them, and maybe encourage you to have a go.

Why You Should Own A Sewing Machine

This could probably be any of our grandmothers at work. George Grantham Bain Collection [PD], via Wikimedia Commons.

In our hackspace, we’ve opened a textile room in the last month. We have high hopes for it as a focal point for cosplayers and LARPers as well as the makers of wearable electronics and more traditional textile users. Putting it in has involved several months of hard work bringing a semi-derelict and previously flooded room that was once the walk-in safe for our local school authority to a point at which it is a light and welcoming space, but a surprising amount of work has also had to go into winning the hearts and minds of our community for the project.

Putting it quite simply, textiles aren’t seen as very cool, in hackspace terms. You know, Women’s stuff. Your mother does it, or even maybe if you are a little younger, your grandmother. It’s just not up there with laser cutting or 3D printing, and as a result those of us for whom it’s a big part of making stuff have had to fight its corner when it comes to resources within the space.

Yet not so long ago when I brought a pair of worn-out jeans into the space on a social night and hauled out our Lervia sewing machine to fix them, I had a constant stream of fellow members passing by amazed at what I was doing. “You can repair jeans?” they asked, incredulously. For some reason this prospect had not occurred to them, I was opening up a new vista in clothing reincarnation, to the extent that before too long in our new facility I may be giving a workshop on the subject as the beloved former trousers of Oxford Hackspace denizens gain a chance of new life.
