Student interns just wrapped up three days in the Innovation Center working in teams to solve a business challenge as part of the CCC Maker Makermatic program. Created by our friends at Sacramento City College Makerspace to meet the internship goals of the CCC Maker statewide grant, and coordinated locally by Seeta (FLC’s Innovation Center Internship Opportunities Specialist), the program was an opportunity for students to propose solutions for business challenges in partnership with Solid Ground Brewing, a local brewery and restaurant. Solid Ground also makes wine, and winemaker Scott came out to the Innovation Center to provide context and listen to student presentations.

The night before final student presentations, Max (Chemistry), CJ (student and Makerspace Facilitator) and I worked to create a gift to present to Solid Ground at the close of the event. We decided to design a beer flight sampler display, with custom-etched flight glasses. CJ fired up Safety Scissors (the name for the smaller of our two laser cutters), and we worked out a design that combined Solid Ground’s logo and Nova, our own space bunny logo/mascot/spirit guide.

Collaborating

Here Max is evaluating different etching parameters. We didn’t have any beer in the space, so we filled the test glass with a combination of soy sauce and water to provide a little contrast while we worked out the details.

Prototyping a Flight Glass Etching

After a few rounds of prototyping – size, placement of thumb and finger indexes, type – we cut, glued, and assembled the pieces.

The glue dry, we sanded away the laser burn marks, friendlied up the sharp edges of the plywood, and sealed everything with cutting board conditioner.

Flight

Each glass has a number etched into Nova’s (our space bunny mascot’s) faceplate, corresponding to a numbered position on the flight corral.

At  the close of the Makermatic event, we took Scott over to the Spider Shed (our nascent brewhouse) to talk about ways we might work together with Solid Ground, and to sample some kombucha Max had kegged from one of our brew days.

Keezer

Max has been perfecting some procedures using Atomic Absorption Spectroscopy (AAS) equipment in the Chem lab, and we talked with Scott about the potential to have students work with local breweries to provide water quality analysis as part of our larger FermSci efforts.

Atomic Absorption Spectrometer

We like traditions in the Innovation Center (things like Builders’ Rights – see ROSTOCK MAX V3 BUILD DAY – PART TWO), and Scott became the first brewer/winemaker to sign our (nascent) keezer!

Toward the end of the party, we walked down to the Harris Center for a preview of some of the visual effects and technical theater magic that will be part of the show, which opens in a couple of weeks.

The show promises to be a technical tour-de-force, with shadow puppets, real-time motion capture, facial recognition, live compositing, and other visually stunning techniques. The Falcon’s Eye Theatre always puts on a wonderfully creative production, and this one looks to be pushing the envelope. Can’t wait for the show!

A few more photos from the event…

Today we got a look at the first prototypes of our mycelium-based 4″ planting pot project. Here’s how they looked, still in the forms.

20190221_103744

The “good” one – the one where the 3D printed PLA positive didn’t deform during the vacuum forming process – is really solid and feels done.

20190221_103819

The second one didn’t want to release from the form, which was not surprising, given how much deformation occurred during thermoformer’s heating cycle, so I had to cut it free from the pot, and use few paper clips to keep the top section attached to the more substantial base.

20190221_105257

Into the dehydrator at 100 degrees Fahrenheit for about three hours, and we’ll see how they feel after that.

20190221_105459

For this iteration, we used oat hay as the substrate, into which we mixed rye berries inoculated with King Oyster mushroom spawn. Since we set up v1, we’ve received a food processor, in order that we might more finely chop up the substrate, and we also have some other substrates in the shop, including rice hulls and various wood chips. V2 next!

Sometimes it seems like there are too many things happening in the Innovation Center to keep track of. This week felt like that. Here’s a recap:

Students in our new ECE course Making for Educators started working on their cardboard pinball machines, which they’ll finish up in our next class session.

Pizza Box Pinball Day 1

Max (student and amateur mycologist) harvested and cooked some pink oyster mushrooms, and pasteurized and inoculated some oat straw, packing it into our first two 4″ pot prototypes, which we made using a 3D printer and our vacuum former.

Mycelium Roundup

Some snazzy new stainless steel fermenting vessels arrived, and Max Mahoney (Chemistry professor and makerspace champion) assembled one in preparation for another brewing day as part of our fermentation science efforts.

Fermenter

Our staff hosted a Palentine’s Day Crafternoon event.

Finally, visitors from both College of Alameda FabLab and Lichen K-8 came out to tour our space and talk about making…

A busy week, and the semester is just getting rolling.

Toward the end of last semester – after lengthy and vigorous and unflinching hacking of red tape – we offered the first workshop – Beer Science: Measuring Beer Bitterness – as part of our ongoing Fermentation Science efforts. We started the day in the Chemistry lab, where Max Mahoney (Chemistry professor and makerspace faculty champion) described the chemistry of beer, and led students through a procedure for measuring beer bitterness.

20181109_122745

Here’s how Max describes it:

The goal of this workshop was to expose students to a quantitative and qualitative analysis of beer bitterness. The chemistry of hops and bittering compounds was presented along with a discussion of the chemical procedures involved in this analysis. The following procedure was used to quantitatively analyze beer bitterness. Three beers were selected containing different levels of the hop-derived bittering agents. Students sonicated the beer to expel carbon dioxide, performed a liquid-liquid extraction of the hop acids with iso-octane, and measured the UV and visible absorption spectrum for their sample. We used the visible absorption spectra to help classify the style of beer. The UV absorption was used to quantify the concentration of hop acids and thus the bitterness of the beer (measured in IBUs).

Chemistry students of all levels were able to learn advanced analytical methods used in the beverage industry to analyze beer bitterness. General and organic chemistry lab techniques were utilized including UV-Vis spectroscopy, usage of micropipettes, and liquid-liquid extraction of organic compounds.

The Chemistry lab portion completed, we went over to the Innovation Center for some blind taste tests. Students sampled various beers, and then used PollEverywhere to report the perceived bitterness of the sample, the results of which we compared to the lab-derived values.

The event was a terrific success, and students were engaged and enthusiastic. We’ve got additional interdisciplinary FermSci workshops and projects planned for this semester, including more beer chemistry, sauerkraut making, curriculum development, and a partnership with a local employer for integrating IOT technology into kombucha fermentation.

You Are Here

We are here.  Diane Carlson (Sociology) and I are co-teaching v2.0 of Making Social Change, a hands-on course at the intersection of making and Sociology, in which we explore social movements and the ways that they use tools to enact change. We teach the class in the makerspace, and we’re working with a brave cohort of interesting students. We’ve been tweaking and adapting the content, activities, and flow, building on what we learned offering a prototype of the course in fall of 2017.

So far, we’ve spoken with Ivan in South Africa, a friend of Diane’s and an ANC activist who fought against apartheid…

Victoire (Communication and Media Studies) dropped by the lab today, and shared an idea she had about creating a puzzle as part of her Group Communications class in the fall. She brought with her a piece of paper with the “Everybody, Somebody, Anybody, and Nobody” story on it, and talked about turning it into a puzzle. We quickly got to prototyping, first on paper, kicking around ideas about the sizes of the words, the individual pieces, and the puzzle overall. We fired up Illustrator to create version 1, which we laser cut on 1/8″ hobby plywood.

Victoire Designs

We immediately agreed that the pieces were too small, the words not legible enough. Back to the drawing board, where we more or less quadrupled the size of the pieces, and changed the letters from vector outlines to raster engraves.

20180809_154858

This version felt more or less right, and then I remembered a project Jeremy (Making Social Change student) had done maybe a year ago, spray painting plywood and then laser engraving that for a white-on-black effect. We happened to have a piece of prepared plywood, which turned out to be the best of the bunch.

Puzzling

After test driving the puzzle, Victoire was satisfied with how it felt, and she was able to set up the laser job and produce enough puzzles to take with her for the first day of class in a couple of weeks.

20180809_161535

Victoire walked in with an idea, and walked out with a v1 prototype about an hour and a half later, feeling super charged up and empowered. Priceless.

As part of the planning for some infosec workshops to be held this coming fall, we decided to prototype a hard drive destruction process using thermite. Max Mahoney (Chemistry) supervised the thermite making, using aluminum powder and iron oxide, with some magnesium ribbon for a fuse. We loaded that into nested clay flower pots, and sandwiched the hard drive between two cinder blocks.

Turns out we didn’t quite kill it.

Data Intact

For our next attempt, we’ll use more thermite, and remove the casing to make the platters more vulnerable. Pretty fun for a first attempt though!

Turns out there isn’t any such thing.

The space – the community, really – feels different these days.  The point at which it becomes difficult to keep track of all the creative things happening is the point at which the community seems to have achieved a level of momentum, of (sometimes shambolic) vibrancy. I open my office door and am surprised by the buzz.  Daily.

Clarity (Making Social Change student and now Innovation Center employee) has continued to work on sharing the laser intaglio process with artists from the college’s printmaking course, here using Illustrator’s Image Trace functionality to achieve a sort of low-resolution abstraction of a photograph of a family pet.

This morning I stumbled upon (or perhaps became re-acquainted with?  Clarity might in fact already be working on it, but it’s sometimes difficult to keep all of the ongoing projects straight) this DIY Printmaking Press project via @joshburker on Twitter.  The files for the press can be downloaded from Thingiverse, and I can’t wait to get one of these tiny marvels printed and up and running in our space!
