Creating an environment where faculty and students collaborate to make things, from Calculus models to history game tiles is one of our goals. The other day, Marc Olsen (Math) and Rebekah Keely (student) worked together to create a unit circle for use in the Trigonometry classroom.
Basing their design on a paper model, they created the vector file using Illustrator – Rebekah has mad skill with this particular program – and then cut the file from 1/8 plywood using the laser cutter.
Marc has ideas about version two, which will have a center post onto which can be snapped some triangles, as in the paper model. Download the file on Thingiverse, or grab the PDF here..
Having recently had students spinning yarn, I decided to make another shuttle for our community loom, as the one we’ve got has a crack in it. I snapped a photo of it, brought it into Illustrator, added a few guides, and was able to pretty quickly create a fairly similar copy.
I cut the shuttle out of 1/4 birch plywood using our laser cutter. It needs a bit of sanding and filing, but I think it will make a pretty decent replacement.
The files (Illustrator *.ai and PDF) and instructions are up on Thingiverse, or you can just grab the pdf here: simple_shuttle
In week 4 of Making Social Change, we talked about Indian independence, and about the emblematic role of khadi – handspun and hand-woven cloth – in the movement. Building upon the prototype Erica Tyler (Anthropology) developed as part of the Making Across the Curriculum faculty maker academy of summer 2016, and on our preview event from spring 2017, students created drop spindles using dowels, hooks, and laser cut whorls.
Erica made herself available to talk about “women’s work” in the Archeological record, and showed students how to spin roving into yarn.
With any luck, the community loom will soon have a bit more handspun yarn added to it.
Gena Estep (History, @HistProfG, she of the history game tile project) and some students have started a Feminist Alliance club (@flc_fems), and Luna (student) and I used the laser cutter to cut a stencil of their rad logo…
About two years from our original idea, and after many hours on the greaseboard, and many prototypes and preview events, Sociology 379: Making Social Change has finally been born! We’re joined by twelve brave, multi-talented, fascinating students, passionate about a wide array of social justice issues.
The class meets once a week on Mondays from 1pm – 4:05pm, and we’ve met twice. We spent the first session framing the course and getting to know each other, doing some design thinking with the help of the Making Connections card game from the Children’s Museum of Pittsburgh, and building some low res prototypes.
In our second session, we took a critical look at the “maker movement,” spending some time discussing “Making Through the Lens of Culture and Power: Toward Transformative Visions for Educational Equity.” (Harvard Educational Review, 86(2), 206-232.Vossoughi, S., Hooper, P. K., & Escudé, M. (2016), https://pdfs.semanticscholar.org/fa5b/4e88c78f380b4727d445afa33bea5212a21d.pdf), before students had the chance to begin work on their contribution to our tile project, which is a low risk/high reward, very accessible “first project” in digital fabrication.
Really looking forward to continuing to work with these students, and to learning from this “version 1” prototype of the course!
FLC’s Science Center runs a series of hands-on Friday science activities, and we decided to support their efforts by creating a collectible sticker for each activity. We based the sizing on the hexbin hexagonal sticker specification, and Rebekah (student) designed and cut a sheet of prototypes…
…which were refined to create version 2.0 (Neuroscience: Brainwaves, Polygraphs, Action potentials, and Remote-Control your Classmates, UCD: College of Agricultural and Environmental Sciences recruiting session, Cadaver Viewing, Cyanotyping, Essential Oil Extraction Using Steam Distillation, Infectious Diseases, Fun Science Activities Suitable for Home, The Innovation Center Makerspace, GIS and Geography)
We’ve moved into production, using our vinyl cutter to create the first batch (for Max Mahoney’s cyanotype activity). Gotta catch ’em all!
The last couple of Fridays we’ve had children from the Folsom Lake College Youth Art Academy in the makerspace. In week 1, two of the three groups worked on building pneumatic monsters…
and paper circuits…
…while Max Mahoney had the third group in the Chemistry lab doing cyanotype photography…
A number of the children were attending both weeks of the camp, so we wanted to mix it up a bit for week two. After researching various engineering challenges, we developed and prototyped a building system of laser cut connectors that could be used with standard popsicle sticks.
We were able to cut 578 per sheet, ~41 minutes per sheet.
The children worked in pairs on engineering challenges, beginning with heaviest weight with minimum sticks…
…and moving on to tallest freestanding structure:
…after which they connected their towers using living hinge bridges laser cut from cardstock, and decorated with LEDs, giving us a chance to talk a little bit about circuits and electricity.
The building system worked surprisingly well for a version 1, and we learned some things – specifically, that the pieces were a little small and the tolerances a little tight for some 8 year olds – that we’ll incorporate into version 2. More photos from the YAA makerspace visit.
The folks from Paton Group came out yesterday to train us on the Roland Modela MDX-50 we’ve got in the makerspace.
First impressions…
The machine is well-built, and the rotary attachment is especially nice, with precisely machined aluminum parts and the most amazingly smooth bearings. It’s quiet, at least when milling chemical wood. It creates a LOT of dust, and took a while to vacuum after the part was finished. The lighting cues are nice, and it’s easy to monitor the machine from anywhere in the lab. The software – SRP Player CAM – is dead simple to use. I don’t have much experience machining, but I was able to pretty easily set up and run a job after being shown the process just once. It takes standard .STL files, so it should be pretty accessible to those with some 3D printing experience.
The model I picked – Totoro by joo on Thingiverse – was maybe not the best choice, in terms of size (I didn’t make the best use of the material) and because of where the supports needed to be (between the ears, though I learned that custom supports can be built into the .STL file to solve such challenges), but I am happy with the result overall. The chemical wood is a new material to me, and is easily worked with an X-ACTO knife, sandpaper, and files.
The Innovation Center recently came by several 100 count boxes of 1 mL and 3 mL syringes, and we set about seeing how we might work them into an activity for an upcoming STEAM camp, inspired by this post from @zackboston…
To start, we duplicated the procedure detailed in the Ivydale video above to create the basic model…
…and then set to work seeing how we might use the laser cutter to create the monster form, with the goal of streamlining the production process to minimize taping and hot gluing. I created several iterations in Illustrator, and the laser made quick work of the card stock. Here’s a closeup of the “final” version, which securely holds the syringe without tape, and which requires only a small bit of hot glue to attach the plunger to the hinge mechanism…
Here’s a pdf of the file used to create the monster. It’s sized to cut two ovals from an 8.5 by 11 sheet of card stock. To make the file work on our laser, the strokes have to be set to “hairline” in CorelDRAW, or .001 weight in Illustrator, pure RGB red (255.0.0). Overall, I’m happy with how it’s working, though the small syringes – a 1 mL on the monster and a 3 mL for the remote – make for a sort of dreamy, organic, delayed reaction that only operates on the push…
The basics established, I set to work creating a mix-and-match, interchangeable eyes-and-teeth system, cut from 1/8″ hobby plywood. I’ll upload the vector files of all of these once I get them finished up. With the laser cutter humming, one idea led to another (as they often do), and I started to wonder how a living hinge might be incorporated into the design. The results are interesting, and there’s probably a whole other related project in there somewhere…
Fascinated by living hinges, Nathaniel (student) and I began experimenting, and were able to take an 8 inch paper hinge…
…and stretch it to 80 inches before it started failing!
Next, I dunked a yet-to-be-expanded laser cut paper living hinge in a mixture of glue and water, and then stretched it out and let it dry…
As predicted, the glue and water mixture stiffened the paper, and it kept its shape (mostly) once dry. There’s a lot to be explored with living hinges – jumping off points include Patrick Fenner’s Laser-cut Lattice Living Hinges, a fascinating look at the math behind them, and this Customizable Tessellating Living Hinge by drxenocide. There’s nothing quite like having the tools, materials, and time to work an idea!
