Mother’s Day approaching!

I just got back from taking my kids to spend a week with my mom, but before I did I snuck into the woodshop for an evening to jumpstart an early Mother’s Day present for her: replacement drawers for her kitchen. She’s been managing with one functioning drawer in there for ages due to broken boxes, busted rails, broken face frames – the kitchen is an early 1970s relic, really. A few hours of work and $20 worth of plywood scrap later, I had them ready to haul to Iowa:

Drawers are a quick build, and a great refresher on some of the woodshop tools.

Over the course of the week we spent at her place, I fixed up her frames, added sturdier drawer supports, installed the new rails and boxes, and put on her old hardware – from the outside you can’t tell anything is different on the ones I finished. I also cut out a sagging cabinet shelf and installed a new one. I left two drawers unfinished, because one of her fronts was missing – I brought the matching front home to bring into the shop and try my hand at copying it. Even with the installation only half done, though, she’s gained a lot of function.

Mother’s Day is just about two weeks away. If your mom has a house full of projects (I suspect this is very common), pop in and use the tools to cross something off her list!

Knit a Working Loudspeaker

knitted speaker

I’ve been working on an embedded speaker design off and on for the last few years, and finally got around to posting an Instructable for it.

I created knitted and non-knitted versions, and am quite happy with how it turned out. The secret is using dipolar magnets and hard drive magnets are a cheap way to do this. (Plus, a really big amp.)

Props to Sache for lending her glue and paper expertise!

CNC Build Club – 2/5/2015 7:00pm

This month’s CNC Build Club meeting will be a demo night.  Bring something to show.  It can be a project you finished, something you made, a work in process or something we might think is cool.

I will be bringing several things I have recently completed.

The bipolar ORD Bot: This is a CNC machine I built for 2015 ORD Camp.  It is a super simple drawing machine with some fun math behind the motion.

The DC Power Supply Interface: This is something I did for Inventables that we will be selling soon.   It really cleans up the wiring when you use a DC power supply on a CNC machine.

The TB6600 Stepper Driver Shield:  This is another Inventables project.  The TB6600 can do a ton of cool CNC stuff.  Now you can interface it to the free grbl CNC controller.

The CNC Club is a monthly meeting of Chicago area people passionate about learning, building and using digital fabrication equipment.  It is held at the Pumping Station One Hackerspace.  It is open to non members.  We also have a Google Group called CNC Build Club.

Each meeting we talk about, build, train on and use CNC machines.  We have 3D printers, laser cutters, CNC routers and vinyl cutters.  Come out and join the fun.

Please RSVP on Meetup.  I will have a CNC or Inventables related door prize to a random person who RSVPs and is present at the meeting.

3D Printed Smallpipes – Part 1

Smallpipes Printing Test RingsScotland is a place that, for the average American, provokes strong reactions. Single malt Scotch whisky. Haggis. And bagpipes. At least in America, the thought of 3D printed bagpipes may inspire fear in some people. Bagpipes were considered weapons of war, and commonly thought to be banned following the unsuccessful Jacobite Rising of 1745. (The Act of Proscription 1746 doesn’t directly mention them, though.) Personally, I’m quite a fan of pipe music, as well as other Scottish folk music, such as the Corries, and the music of Nova Scotia, especially Mary Jane Lamond.

I bought a Highland bagpipe practice chanter years ago, only to discover that the angle I had to hold it to keep my fingers in the right position was torture on my wrists. I figure it would be more comfortable to play when attached to an actual bag. But acquiring a full set of Highland bagpipes wasn’t terribly practical, and that would probably lead to my neighbors breaking down my door and coming after me with torches and pitchforks should I try to practice indoors. Or at least they’d complain to the condo association. So I forgot about that for a while.

Then in spring of 2014 I saw the Dreaming Pipes Kickstarter posted by Donald Lindsay of Glasgow. He was creating a 3D printed chanter with a customized extended range for the Scottish smallpipes, which are, as their name suggests, smaller, and designed to be played indoors. But he was also creating plans for a full set of smallpipes modeled off a 17th century design that could be 3D printed, with a laser cut bellows. And he was also designing 3D printed Highland bagpipe drones. I’ve got access to four 3D printers and a laser cutter at Pumping Station: One. It looked like fun to build. So I backed it.

Maker Art: (Another) Opening Tonight in Pilsen

DSC_6394 group

My knitted-circuit artwork, Electronic Damask, was in a gallery show, NoFi, at Chicago Artists Coalition, October 24 – Nov 13. The piece was a collaborative effort, put together through the volunteer efforts of close to two dozen PS:One members. PS:One really represented at the Oct 24 opening, and I managed to drag most of us in front of the camera for a group photo with the artwork. (Thanks to Everett for the photo!)

If you missed the fun that night, you’re in luck. Electronic Damask has already been tapped for another show, and with an opening tonight in Pilsen, from 6 – 10pm.

This show should be of particular interest to PS:One members. It’s called Technologic and it “celebrates making art through technology”. It features some amazing stuff made with 3D printers, LCD screens, CNC watercolor painting, and of course a certain knitted e-textile.

The gallery, Chicago Art Department, is located at 1932 W Halsted in East Pilsen’s Chicago Art District (#8 Halsted bus runs right past it). Tonight’s opening coincides with the district’s 2nd Fridays gallery night, so there will be other openings all over the neighborhood.

You can find preview photos of the show on the facebook page. Full info is below. The show runs until December 6.

TECHNOLOGIC
curated by Chuck Przybyl

Friday, Nov 14, 6-10pm

An exhibition that celebrates making art through technology. Work featured will include robotic drawing, 3D printing, laser cutting, textile circuitry, algorithmic art, image slicing, circuit bending, and prosthetics. Although often unsung – artists having access to new technologies has historically pushed and propelled creative endeavors. The exciting new technologies of today have been pushing the overall culture of DIY and propelling the Maker Movement. This is a participatory culture that embraces tools and empowers masses of people to innovate and create. Technologic explores and showcases not only how art is currently being produced with new tools, but how fringe technologies can be used in progressive and cutting edge ways.
Viewers also have an opportunity to “go deeper” to gain further insight through series of discussions and workshops as well information on the processes at the exhibit.

Technologic is curated by Chuck Przybyl for Chicago Art Department.
Artists: Tom Burtonwood, Christopher Furman, Harvey Moon, Luftwerk, Jesse Seay, Nathan Davis, Christopher Breedlove, Christian Oiticica, Leo Selvaggio, Antoine Kattar, and Russell Prather

Opening Reception Nov. 14 – 6-10 PM
3D Printing Workshop with Tom Burtonwood Saturday Nov – 15 – 2-5 PM
Panel Discussion  Saturday Nov – 22 – 2-5 PM

Laser cut some simple masks for Halloween

Masks-graphic-WEB

 

There are a lot of online mask patterns that can be printed and cut out with scissors, but it would be much nicer to laser cut one. Let the laser do the hard work. I did these four mask designs tonight; they are perfect for a last minute costume for makers on the go or their kids. Now you can put the roll of toilet tissue back and do better than being a mummy this year. Download the patterns on Thingiverse here.

Moldy Kodachrome under the SEM

201408_MudMask_Contact_012

This past week I had the chance to look at a damaged piece of Kodachrome film using the SEM. Many thanks to Ryan for being an SEM sensei and preparing my sample!

I had recently acquired a box of sixty year old slides from my grandfather, visibly moldy and containing almost no recognizable subjects. The Kodachrome frames are unlabeled except for one: “Pat” written in pencil. I digitized them using a high res flatbed scanner and the resulting images are abstracted, textural, wrinkled, aged, rotten layers of purples and browns. In a few of the slides, a section of a window is visible, a head of a horse, two posed women. Pat turned out to be totally enshrouded in a mold veil, like most of the images. She along with the other photographic subjects had been displaced by  abstracted, festering growths.

Sinewy veins stretch across, interspersed with round sacs and sac covered cylindrical pellets. Some other spherical growth breaks the surface creating a hungry alien mouth form. These images got me thinking about the many complicated layers of cultural artifacts. The film slides are part of my family archive, they indicate 1950’s photo technology, they’re fragile physical objects susceptible to mold growths. What do valued objects/ object of nostalgia become when they are separated from their initial purpose? What does it mean to keep a box of film if the intended images are no longer there? The photographer, the creator of the original image, has been deprived of his control as biological functions resulting from imperfect environment and time have taken over.

In a sense, I hope to continue the life of these objects by pushing them into their new life as veiled, abstracted images, reminders that physical world continually effects our efforts to preserve and keep stagnant. While I don’t know who Pat is, or what she looks like, I have a pretty incredible image of something related to her.

Laser Collage version 2.0: The Eric Carle Method

Squid Attack by Shellie Lewis, paper, acrylic paints, gel medium, Micron pen, vector design and laser, 7.5 x 9.5 inches, 2014.

Squid Attack by Shellie Lewis, paper, acrylic paints, gel medium, Micron pen, vector design and laser, 7.5 x 9.5 inches, 2014.

The next logical extension of the Laser Collage process is something I call The Eric Carle Method. Children’s book author Eric Carle is known for his collage are using his hand painted papers. The main difference is that you are adding paint to the process rather than using ambient papers or recycled materials for the collage art.   Squid Attack 02   I had a clear idea of what I wanted in this design and drew the squid and submarine in Adobe Illustrator using the pen tool. That step took me at least three hours. I used a Gelli Arts soft monoprinting plate to roll acrylic paints onto and made the color combinations I wanted for scene, aiming for a red / blue /yellow primary color scheme. This version pops out and seems more playful. I may try a version with darker colors and low intensity hues to see if it looks more realistic. Today, I was just aiming for a fun picture. My paper was an 80# weight cardstock with a hard, smooth finish. This paper held the acrylic paints well with little to no warping and dried fast. I used the Epilog Mini laser to cut and etch my drawings. The vector cutting was at speed 20 / power 25 / hz 500. Only the slightest edge of the design had a sign of the laser, literally just the plane the thickness of the paper; viewed from above there was no visible scorch. The acrylic paints had some resistance to being etched and I used speed 100 / power 50 to etch the eye and a few lines.   Squid-Attack-03   Matte acrylic gel medium glued the arranged layers together. Boards and wax paper were helpful to press the art flat. I used a Micron pen to fill in the etched lines on the body and for the eye and some thinned white acrylic paint for highlights and reflections. I’m really happy with how my giant squids came out. This was unfortunate for anyone who was at the space today because I went around with them when they were done. It’s not often that someone comes up to you and asks, “Have you seen my squids?” File that under the heading “Because: Hackerspace.”

ShapeOko Building Adventures So Far

Inventables donated a ShapeOko 2 CNC Router “The Works” kit to Pumping Station:One, and we’ve been doing a group build over four sessions so far. It’s been a chance for people to learn about open hardware and CNC firsthand from the ground up, and participate in making PS:One’s next machine. We’ve had participants with various levels of experience working together, and I think everyone learned something new.

During the first session, we assembled wheels and bearings, and attached them to plates for the x, y,and z axes. We started the next session with parts that looked like this:

shapeoko2-6

The instructions describe the z-axis assembly as the most intricate, and they’re not kidding. It took a lot of fiddly work and some mistakes to get here:

shapeoko2-7Here are some of the participants, planning what to do next:

shapeoko2-2We assembled the carriages, then the gantry and machine frame. The machine came together well during this session:

shapeoko2-8I think #1177 (“Minion”) the ShapeOko1 is jealous of its newer, larger, and shiner sibling #5549 (so far unnicknamed):

shapeoko2-1During the third session, we squared and wired the ShapeOko and installed the drag chain (“e-chain”) with some help from Zach from Inventables.

shapeoko2-5During the fourth session, we nearly finished the wiring and made a custom holder for the emergency stop button:

shapeoko2-4Thank you to everyone who helped so far! Our next build session will be Thursday, August 28th at 7pm in PS:One’s shop. We’ll be testing the motors, troubleshooting, and sending the “hello world” job. Come see the machine move!

Thank you Ron (I think) for the Session 2 photos and Allen for the Session 3 photo.
