In a haze of coding, caffeine, circuits, teamwork, snacks, and sleep deprivation, around 120 students from Calvin and other universities worked for 24 hours straight, developing a wide range of software and hardware computing projects. The students were competing in Calvin’s first “hackathon,” a marathon software and hardware development competition held from February 8-9 by the CalvinHacks student organization.


As the sun set on February 9, a team of Calvin students emerged victorious, their project—PlantBit—scoring first place. A combination of a smartphone application, an arduino board, a Google Home, and a moisture sensor, PlantBit allows its user to remotely turn on and off grow lights for their plants, while also providing data on the moisture of the plant’s soil.


“It was inspired by the massive amount of succulents I keep in my room,” said team member Lauren Ebels, a biology and computer science major. “I have a whole bunch of grow lights for them, but couldn’t set them to be on when they’d help the plants the most.”


Over the course of the 24 hours, the team divided and conquered: Junior Shion Fukuzawa programmed the remote control iPhone app, Seniors David Widjaja, Megan Koh, and Toussaint Cruise set up the hardware and control database, and Ebels connected the Google Home to the control database.


“There’s a sense of accomplishment,” said Fukuzawa, a math major and computer science minor. “At the end you have to submit something no matter what, and the fact that you worked as a team for 24 hours and actually made something is pretty satisfying.”


“CalvinHacks was a really fun event, and was unlike anything I had ever done before” said Caleb Schmurr, a Calvin junior electrical engineering student whose team worked on a project using an e-ink screen to display information from a Google Home.


“I liked getting the chance to spend time working in an environment that encouraged and supported creative uses of technology,” Schmurr added. “We were able to use our programming abilities gained from either coursework at Calvin or other experiences to create a really unique project.”


Among a multitude of other creative submissions, Calvin teams also designed a web-based video game, a sign language video detection user interface, and an app for tracking grocery purchases.

Calvin engineers take second place at Disaster Shelter Design Competition

Calvin College placed second at the 7th Annual Disaster Shelter Design Competition, sponsored by Samaritan’s Purse International, April 19-21, and hosted on John Brown University’s (JBU) Siloam Springs campus. Nine teams from eight universities designed and constructed a rapidly-deployable emergency and disaster shelter, which a panel of judges with expertise in emergency management, engineering, logistics, and manufacturing, evaluated for possible implementation in relief efforts worldwide.

 

“It was a lot of fun. We got to test our prototype against other schools and other designs, simulate a lot of scenarios, and ultimately we got to see how well our process and ideas came to light in physical form,” said Kyle Sutton, a senior civil-environmental engineering major at Calvin.

 

Sutton, along with fellow senior civil-environmental engineering majors, Kyra Black, Cameron Carley, and Nate Veldboom, made the 13-hour drive south for the competition. The group, known as Team Dwell, brought with them their handiwork–a project they’ve been working on for their senior design project this year.

 

The competition scenario they participated in was based on the 7.8 magnitude earthquake in 2015 that affected more than a million people in Nepal. The shelters were required to address the local climate in Nepal, as well as their mountainous terrain, by retaining heat and transporting easily as well as by being water resistant, cost effective and culturally appropriate. The shelters were also required to be able to house a family of four.

 

“This competition gives Samaritan’s Purse access to some of the region’s most innovative engineers, construction management and architects, as students provide practical solutions to real-world problems,” said Mark Terrill, associate professor of construction management at John Brown University, and competition coordinator. “Not only does the competition combine classroom learning and real-world application, but it’s also really fun to watch.”

Each team’s disaster shelter prototypes endured durability testing – including earthquake sustainability, heat retention, overnight habitability, wind turbulence, and water resistance. In addition, teams competed in an emergency shelter construction test, where they were evaluated on their ability to quickly design and construct emergency shelters from given materials.

 

Teams were scored based on their shelter’s performance in individual events and on their presentations detailing their shelter’s schematics, design, and materials. In addition to Team Dwell’s second place overall finish, they also took top honors in the Best Camp Plan, Best Report/Presentation, and Lightest Shelter categories.

 

A team from LeTourneau University took first place overall and John Brown University took third place. Other universities who participated this year include: Dordt College, Pittsburg State University, Gyeongsang National University, Murray State University, and University of Arkansas at Little Rock.

As astrophysicist Neil deGrasse Tyson makes his way to Grand Rapids this month, the Grand Rapids Public Museum sets the mood with a number of family activities in March all centered around science.

 

This week, the GRPM hosts its annual celebration of engineering week with school groups participating in an integrative Science Technology Engineering and Mathematics experience featuring activities from science and engineering. The week culminates in a public day Saturday, March 5.

 

“Basically all the stations that the school groups go through during the week are available for the public on that Saturday,” said the museum’s Marketing Manager Christie Bender.

 

Saturday’s programming focuses on STEM applications to create real world solutions to human problems and needs. Stations include creating underwater submersibles, design bridges, exams biomedical devices, manipulate robots, experiment with water systems and create concrete cookies using household ingredients.

 

“There are also special audience interactive events on the fifth where they can help drive an underwater rover that is in Florida waters from the Museum’s Theater,” Bender said. Underwater researcher and scientist Chris Olstad,and Grand Valley State University Professor Mark Gleason will be hosting live presentations at 10:30 a.m. and 11:15 a.m. from thirty feet below the water’s surface in Florida waters.

 

The GRPM also will be continuing its new, ongoing program Science Tuesdays, focusing on Zoology for the month of March. Stations will include hands-on activities, microscopes, animal x-rays, honey bee information and live animals every week. Today and March 8, animals from the John Ball Zoo will be at the GRPM from 10 a.m. to 2 p.m. Blandford Nature Center will bring in animals on March 15 and 22 from noon to 1 p.m. and 2 to 3 p.m. Dr. Rebecca Vincent will have animals from noon to 4 p.m. March 29 and she is also scheduled to be the guest speaker at 6 p.m. that day. Vincent will discuss wildlife rehabilitation. Presentations are free with general admission.

 

Also this month, the Grand Rapids Amateur Astronomical Association with the GRPM will be hosting the Winter Star Party March 11 and 12 at the Cascade Recreation Park, 3810 Thornapple River Dr. SE. The program is from 7:30 – 9 p.m. both days.

 

GRAAA members will have telescopes set up to allow public viewing of the crescent moon, Jupiter and various other sky features visible only during winter and early spring. During warm weather season, these features are below the horizon making them unable to be seen. Those attending this event are encouraged to dress for cold weather and to bring flashlights, binoculars and telescopes if available.

 

This event is weather dependent and will only take place if the sky is clear. Status updates will be posted on the GRAAA website, graaa.org.

 

For more information on these events, upcoming exhibitions or other activities at the Grand Rapids Public Museum, visit grpm.org. The Grand Rapids Public Museum is located at 272 Pearl St. SW.

 

Neil deGrasse Tyson comes of Grand Rapids March 21. He will be at DeVos Performance Hall, 303 Monroe Ave. SW.
