New IDEAS Lab Offers State-of-the-Art Digital Fabrication Tools

 Assistant Professor of the Practice Daniel MollerIDEAS clasroom

Daniel Moller, assistant professor of the practice in integrative sciences, is teaching Introduction to Design and Engineering inside the new IDEAS Lab this fall semester.

Equipped with 3-D printers, water-jet and laser cutters, computer-operated milling machines, and high-tech drills, saws, and workstations, Wesleyan’s new IDEAS Lab is on the “cutting edge” of digital fabrication.

Wesleyan’s new ProtoMAX water-jet cutter created this butterfly out of aluminum in 18 minutes.

This fall, the College of Integrative Sciences opened the adjoined classroom and makerspace in Room 40 of Exley Science Center. While it is currently used by students in the IDEAS (Integrated Design, Engineering & Applied Science) program, by spring 2020 the space should be open to the entire Wesleyan community.

“The space is the heart of our efforts to provide students with a facility to explore their ideas and create new projects,” said Francis Starr, IDEAS coordinator and professor of physics.

The IDEAS program prepares students to succeed at the intersection of design, the arts, and engineering. Students hone skills in identifying which scientific and engineering principles need to be understood to achieve design goals, and use computer-aided design (CAD) software and fabrication tools in the lab to create a solution for their design. Students also develop foundational knowledge in design and engineering by working in collaborative groups on project-based studies.

While much of the new lab equipment was purchased by the University, lighting solutions company OSRAM, based in Beverly, Mass., donated dozens of fabrication tools and parts to Wesleyan this summer. The lab’s professional-grade 3-D printer, computer numerical control router, and vortex dust collector were part of the donation, which collectively are valued at approximately $500,000.

“The donated items allow us to offer students access to a number of tools that they would otherwise not get a chance to experience,” said Professor of Physics Brian Stewart, who spearheaded the OSRAM donation. “We’re also moving closer to establishing an advanced lab in the Physics Department, so the donated vibration-free laser tables, hardware, and electronic equipment will serve as the nucleus of this exciting new departmental project.”

The 75-watt engraver uses a CO2 laser, pulsing at 2,500 cycles per second, to cut into a sheet of wood.

The lab’s water-jet cutter slices through flat sheets of metal, tile, stone, and plastic using 30,000 psi of water and garnet abrasive material.

The IDEAS Lab milling machine uses various drill bits to cut and carve 3-D objects from solid materials such as metal, wood or plastic.

The multi-axis computer numerical control router, or milling machine, uses various drill bits, as well as a 4th axis lathe attachment, to cut and carve 3-D objects from solid materials such as metal, wood, or plastic. After programming the paths using appropriate software, the process is almost entirely automated. “Most of our CNC machines are really designed for cutting material in two dimensions,” Lopez said. “What if you want to actually carve a piece of metal in three different dimensions? This mill is the kind of device that can actually do that.”

OSRAM donated multiple laboratory oscilloscopes, which are used to display and analyze the waveform of electronic signals. Three have already been installed in the Exotic Wave Lab managed by Fred Ellis, professor of physics. “Numerous research groups have already benefited through the acquisition of individual pieces of equipment: oscilloscopes, digital delay generators, and other hardware have satisfied needs or increased capabilities in most of the department’s experimental laboratories,” Stewart said. “This is particularly welcome as our ability to accommodate additional undergraduate students into our research labs is often limited by the availability of equipment for new or exploratory projects.”

In addition to digital fabrication machinery, OSRAM donated thousands of pieces of optical equipment to Wesleyan.

The IDEAS Lab is located on the ground floor of Exley Science Center.

The Next New Things: Presenting Final Projects in IDEAS 170

In December, the students of IDEAS 170: Introduction to Design and Engineering presented inventions of their own design. These final group projects are possibly the next new life hacks everyone will crave: a projector that doesn’t rely on electricity (great for watching movies when the power is out), a chair that folds flat (packs easily and saves space), or a dorm room light that mimics the sun (helps set your sleep/wake cycle naturally).

Additionally, one group of Wesleyan students collaborated with students from Renbrook School in West Hartford. Betsy Flynn, Lower School Learning Specialist at Renbrook, explained: “The Renbrook students brought their accessible playscape design to Wesleyan and pitched their idea to the class on the same day that other project ideas were pitched. Then the Wesleyan team came to Renbrook with several elements of their inclusive playground to get feedback from Renbrook students. They spent an hour together getting to know each other and had a spirited discussion of what each had in mind in their designs.”

On the day the final projects were presented, the Wesleyan students set about creating a one-inch scale prototype of the playscape, inviting their younger collaborators to visit the University to see how their initial ideas had taken physical (albeit miniature) form.

The two IDEAS sections of the fall 2018 semester, taught by Professor of Physics Greg Voth and Assistant Professor of the Practice in Integrative Sciences Daniel Moller, offered 32 students the opportunity to work collaboratively on project-based studies at the intersection of design, the arts, and engineering. The course, part of a new interdisciplinary minor, the Integrated Design, Engineering, and Applied Sciences (IDEAS) program, is hosted and administered by the College of Integrative Sciences (CIS).

Wesleyan (issue 3, 2018) featured the course in its cover article, Putting the Art in Smart Design, following the students through the first half of the course as they worked on individual devices that would hop after a timing mechanism released. A video, “The Big Hopper Reveal,” illustrated their design and engineering work at the semester’s midpoint. The photos and video below, taken at the end of the fall 2018 semester, show the group inventions. (Remember: You saw them here first). (Photos by Cynthia Rockwell)

Students “Hop” into Midterms with Design and Engineering Project Presentations

Students who are enrolled in the fall semester Introduction to Design and Engineering course presented their midterm projects on Oct. 17 and 18. At the beginning of the semester, the students were given a box of materials and tasked with creating a “hopper”—an object that would spring into the air but only after a delay of 8 seconds (and less than 60 seconds) from when the student released the object.

After designing the hopper, and (often) creating multiple prototypes, students used laser-cut wooden pieces, rubber tubes, ball bearings, capacitors, balloons, wire, and other equipment to fabricate their final ideas.

The Introduction to Design and Engineering course, which provides a hands-on introduction to design and engineering, is taught by Greg Voth, chair and professor of physics, and professor, integrative sciences; and Daniel Moller, assistant professor of the practice in integrative sciences. It is part of Wesleyan’s Integrated Design, Engineering, and Applied Science (IDEAS) program, which prepares students to succeed at the intersection of design, the arts, and engineering. Through the program, students develop foundational knowledge in design and engineering by working in collaborative groups on project-based studies. The IDEAS program is hosted and administered by the College of Integrative Sciences.

Wesleyan’s Natural History Collection and Curiosities Featured in Usdan

The exhibit "Shelving the History of Life" will be featured inside the display cases in Usdan Universiy Center throughout the fall semester. The true-to-scale exhibit showcases specimens curated, restored, prepared, and documented from the Joe Webb Peoples Museum of Natural History, the former Wesleyan Museum, and other collections on campus.

The exhibit “Shelving the History of Life” will be featured in the display case in Usdan University Center until fall recess. The exhibit showcases specimens curated, restored, and documented from the Joe Webb Peoples Museum of Natural History, the former Wesleyan Museum, and other collections on campus.

In 1870, Orange Judd bequeathed Wesleyan $100,000 to build Judd Hall, which was designed as a building for the study of natural sciences. Included with this building was the Wesleyan Museum, which housed a prominent natural history collection containing over 300,000 specimens.

In 1957, the museum was closed and specimens were donated to other museums, put into storage in various places on campus, or “temporarily” loaned to local schools. In 1970, before the current museum reopened in Exley, the collection stored in the tunnels under Foss Hill was found to have been severely vandalized, with many specimens lost, stolen, or irreparably damaged.

Within the last two years, several Wesleyan faculty, students, and staff have exhumed thousands of these misplaced artifacts and are working to bring them back for public viewing. A new exhibit in Usdan, “Shelving the History of Life,” showcases many of these once-lost, and now found, relics of Wesleyan’s natural history collections.

“This exhibit is a showcase of the spectrum of natural history objects remaining in our collections, including taxidermy specimens, a wide range of wet specimens preserved in alcohol, skeletons, seashells, fossils, and minerals,” explained Andy Tan ’21, who is one of the cocurators of the exhibit.

Students Showcase Design and Engineering Projects

Final projects for Introduction to Design and Engineering (IDEA 170 in the Integrated Design, Engineering, and Applied Sciences Minor) included a bicycle powered by a chainsaw motor; reusable, lockable shipping boxes requiring no tape; an electricity-producing dance floor; and the “solar rover”—solar panels with storage batteries mounted on wheels and designed for long-term use around the University as a mobile power source for events and solar power education.

Taught by Professor of Physics Greg Voth, who chairs the department, and Assistant Professor of the Practice in Integrative Sciences Daniel Moller, the course offered 16 students the opportunity to work collaboratively on project-based studies at the intersection of design, the arts, and engineering. The course is part of a new interdisciplinary minor, the Integrated Design, Engineering, and Applied Sciences (IDEAS) program, hosted and administered by the College of Integrative Sciences (CIS).

Professor of Physics and Director of the CIS and the IDEAS program Francis Starr noted, “These projects are amazing examples of what Wesleyan students can do when given the skills and opportunity to creatively explore design and engineering. And I think this is why we have already seen about 30 students enroll in the new IDEAS minor in just its first year. I can’t wait to see what next year brings.”

Moller concurs: “IDEA 170 is a great opportunity for students to explore an open-ended design and fabrication environment, to recognize the technical challenges of putting ideas into action, and to learn about themselves as designers.”

Thomas’s Science Paper Examines Earth’s Oxygen Levels over Geological Time

Ellen Thomas

Throughout time, rising oceanic and atmospheric oxygen levels have been crucial to the habitability of environments at the surface of the Earth.

“The Earth had no free oxygen gas in its atmosphere early on,” said Ellen Thomas, the Harold T. Stearns Professor of Integrative Sciences. “The oxygen has been provided over time by photosynthesis of algae followed by storage of organic matter in rocks.”

Thomas, who also is research professor of earth and environmental sciences, examines the timing of oxygen formation in Earth’s atmosphere and oceans over geological time in a study published in the May 2018 issue of Science.

The paper, titled “Late Inception of a Resiliently Oxygenated Upper Ocean,” stems from a multiyear, multinational, multiauthor research effort that explores the time trend and causes of increased oxygenation during the current Phanerozoic Eon, which began more than 542 million years ago. Thomas and her colleagues used iodine geochemistry to determine that the upper section of the ocean became rich in oxygen much later than previously predicted, linked to evolution of oceanic phytoplankton.

The research was supported by a National Science Foundation grant at Wesleyan and coauthored by scientists at Syracuse University and the University of California, Riverside.

The study also is featured in the May 2018 issue of Science Daily and Phys.org.

Robinson Lab Coauthors Study on Compulsive, Drug Addiction Behaviors

Mike Robinson studies how individuals react differently when presented with a junk food diet.

Mike Robinson

Drug and behavioral addictions like gambling are characterized by an intense and focused pursuit of a single reward above other healthier endeavors. Pursuit of the addictive reward is often compulsively sought despite adverse consequences.

In a newly published study, Mike Robinson, assistant professor of psychology, neuroscience and behavior, and integrative sciences explored how our decisions can become narrowly focused onto one particular choice. He and his research team used laser light (optogenetics) to activate the central portion of the brain’s amygdala (CeA), an area normally known for its role in generating responses to drug-related and fearful stimuli.

The study, titled “Optogenetic Activation of the Central Amygdala Generates Addiction-like Preference for Reward,” appears in the May 2018 issue of the European Journal of Neuroscience. Robinson Lab members Rebecca Tom ’16, MA ’17, Aarit Ahuja ’16, Hannah Maniates ’16, and current graduate student Charlotte Freeland coauthored the article and participated in the study.

Giant Glyptodon Emerges in Exley Science Center

Stearns Professor of Integrative Sciences; Annie Burke, chair and professor of biology; and David Strickland, instrument maker.

The Glyptodon, a giant fossil cast that has been in storage since 1957, is now on display in Exley Science Center. Several members of the Wesleyan community helped install the 8-foot-long cast on Feb. 26. Pictured, from left, are Joel LaBella, facility manager for the Earth and Environmental Sciences Department; Bruce Strickland, Instrument maker specialist; Jim Zareski, research assistant/lab manager for the Earth and Environmental Sciences Department; Freeman Scholar Yu Kai Tan ’20; Freeman Scholar Andy Tan ’21; Ellen Thomas, the Harold T. Stearns Professor of Integrative Sciences; Annie Burke, chair and professor of biology; and David Strickland, instrument maker. Glyptodon means “grooved or carved tooth” in Greek. The creature lived approximately 2 million to 10,000 years ago.

The Glyptodon as seen from the front (upper) and back (lower) in its glory days, when it was displayed in the Orange Judd Museum of Natural Sciences, before 1957. Note the skull and hind left foot present, and the armored tail visible from the rear. Copy of 1876 advertisement by Ward, dated 1876, in which he names ‘the Wesleyan University of Middletown, Conn.’, as having purchased a number of his ‘Casts of celebrated Fossils’.

Prior to 1957, the Glyptodon was displayed in the Orange Judd Museum of Natural Sciences. Pictured in the center is an 1876 Ward advertisement, in which he names “the Wesleyan University of Middletown, Conn.” as having purchased a number of his “casts of celebrated fossils.”

For the past 60 years, a massive megafauna mammal thrived in crates buried in Wesleyan’s tunnels and attics. This month, the creature, known as a Glyptodon, has emerged in Exley Science Center for public viewing.

Although the armored armadillo-like animal became extinct more than 10,000 years ago, Wesleyan acquired a fossil cast in the 1870s, where it became a showpiece at the university’s Orange Judd Museum of Natural Sciences.

In 1957, the museum closed and thousands of artifacts, including the Glyptodon, were haphazardly stuffed into crates and boxes and hauled to multiple locations throughout campus.

“After the museum closed, everything was scattered all over, anywhere there was a place to put it,” said Ellen Thomas, the Harold T. Stearns Professor of Integrative Sciences and research professor of earth and environmental sciences. “Just recently, we’ve started to uncover all these lost treasures and we’re working to get them organized and cataloged. The Glyptodon is one of our major finds.”
