“Gadgets and Gizmos” was the theme for the first HWeekend of 2017 on January 20-22, jointly sponsored by the College of Business and the College of Engineering.
In just one weekend, forty-seven students from business and engineering designed, built, and pitched their idea for a marketable product including temperature based alarm clock, a computer controlled potato launcher, a 3-D printed longboard fender, and a self-playing guitar.
It was the seventh iteration of the popular event that provides students from different disciplines an opportunity to work together in teams. Students came from a variety majors including business, bioengineering, civil engineering, chemical engineering, computer science, electrical and computer engineering, environmental engineering, and mechanical engineering.
“This event is really cool, because I get to do things that I normally don’t get to do in my major,” said Alec Westbrook, a chemical engineering student who worked on the 3D printed longboard fender project. “I mean, how often can a guy that is mixing chemicals all day work with his hands and create something new?”
Mentors for this HWeekend included six industry members from Intel and two from Microsemi.
“People here are really excited about the things they are making,” said Aayush Pathak, a silicon architecture engineer from Intel who attended HWeekend as a mentor. “And to be a part of it and share what I have seen in my school and life — it’s a proud feeling.”
Staff from both the College of Business and the College of Engineering also helped mentor students through the creation and marketing of their projects.
“It’s an incredibly valuable partnership between business and engineering,” said Dale McCauley, the makerspace manager for the College of Business. “The students are getting the chance to build relationships that ordinarily wouldn’t form. If you get business students to understand how engineers think and vice versa, I think that is valuable.”
At the end of the weekend, the students received group awards for their dedication and hard work. The Executors award goes to the team that produces the best engineering execution of their idea to create the most polished final product, the Helping Hand is for the team that contributes the most to other teams, and the InnovationX Pitch awards go to two teams who had the best business pitches for selling their prototypes.
Executor: Temperature Based Alarm Clock team. The team included members Noah Hoffman, Taylor Johnston, Alexia Patterson, and Abdurrahman Elmaghbub.
Helping Hands: Checkpoint team. The team included members Andrey Kornilovich and Graham Barber
InnovationX Pitch: Checkpoint team and Temperature Based Alarm Clock team.
Students spent 30 consecutive hours of engineering design, teamwork, and development at HWeekend on October 8-9, sponsored by the College of Engineering. The theme was “Show’em What You Got!”, and participants did just that, creating some of the most complete projects of any HWeekend. The purpose of the theme was to encourage projects that could be submitted to national competitions.
It was the sixth iteration of the highly successful event that gives engineering and business students an entire weekend to develop an idea and prototype it. Forty-two students participated with majors in electrical and computer engineering, computer science, mechanical engineering, nuclear engineering, and finance.
After some breakout brainstorming sessions and presentations of their ideas, participants split into 10 teams to work on their projects. The diverse ideas included a modified game of laser tag, a guitar that could tune itself, and a smart shin guard paired with a virtual reality environment.
One of the groups returned from the previous HWeekend held during Spring term. That group continued with their effort to build a ferrofluid display using individually wound electromagnets. The other groups were much newer to their projects, such as the mobile coffee heater group, which worked on finding components they could use to heat liquids in a drinking cup.
“The beautiful thing about this is that it’s fast paced and you really see results, even if they’re not exactly the results you hope for,” says Audrina Hahn, a mechanical engineering student, who worked on the Open Laser Tag project.
This event made use of the all-new Buxton Hall Makerspace, the Mastery Challenge lounge, and the Virtual Makerspace, which gave students access to 3D printing, soldering irons, a drill press, and laser cutting.
“It’s really amazing all the resources that we have available to us that are really simple to use and are things that are up-and-coming that we will probably continue to use into our careers,” Hahn says.
Mentors for this HWeekend included eight industry representatives. Martin Held from Microsemi returned to guide teams and answer hardware questions. Multiple mentors arrived from Intel in Hillsboro, including several recent graduates of Oregon State. These mentors split up to help on projects where their experience helped groups work with unfamiliar technologies. One group that benefitted was the motion tracking robot team, which received help with OpenCV from a mentor who revealed a personal interest in assembly programming.
Ben Buford was one of the recent graduates who came back from Intel to provide mentorship. He spent most of his time contributing to the ferrofluid display.
“I love seeing people come up with quick solutions that let them accomplish something and overcome obstacles that they didn’t know existed three hours prior,” Buford says.
Beyond the satisfaction of completing prototypes of their ideas, students at HWeekend compete for two group awards. The Executors award goes to the team that produces the best execution of their original idea to create the most polished final product and the Helping Hand is for the team that contributes the most to other teams. At this HWeekend, the Arbitrarily Tuned Stringed Instrument team was selected for both awards. The team included members Keaton Scheible, Youthamin “Bear” Philavastvanid, Elliot Highfill, and Savannah Loberger.
Danny Dig and his colleagues discovered widespread problems in mobile app development that can cause applications to be unresponsive and “freeze.” After looking at over 1,000 open-source mobile apps, they found two main problems — underuse and misuse of asynchronous programming.
“It’s very easy, if you are not careful, to write a mobile app that is unresponsive,” Dig says. “The number one culprit for a frozen app is that a programmer has written a blocking call, such as accessing the cloud, on the main thread that processes other user-interface events and actions.”
The solution is to move the blocking calls into the background with asynchronous programming. Dig’s team has sent out hundreds of patches to developers to fix the problems in their code, and they have created tools that developers can use to find and fix asynchrony errors. Their webpages LearnAsync.NET and refactoring.info/tools give many examples of asynchronous programming and access to the tools.
“Now what I want to do is help people avoid making those mistakes in the first place,” Dig said.
As part of his educational efforts, Dig will be presenting in Portland, Oregon for the Technology Association of Oregon in June. The cost is $25 for members and $45 for non-members.
The presentation will be a technical overview of why asynchrony is important, it will include descriptions of the common pitfalls and best practices, and he will also demonstrate the tools he has developed.
“I see this as a way of transferring knowledge from research into practice, but it’s also important for me to have a dialog with programmers. I bring back their feedback to the research,” Dig said. “So, this is a fabulous event for me to establish those connections.”
Computer science freshmen, Brett Case, Logan Phipps and Taegan Warren had completed just one computer science class at Oregon State University, but their lack of expertise didn’t stop them from participating in QuackHack. The 40-hour gaming hackathon, held at the University of Oregon, challenged students to take an idea for a game and create a working prototype in a single weekend.
The trio entered the event for the learning experience and to see if they could create something with the basic programming skills they acquired in their introductory computer science class.
To their surprise, the virtual card game they created — in which players build hamburgers and feed them to the opponent — won an honorable mention for Best Scope, awarded to a team that had a reasonable goal and excellent execution of that goal.
“The judges were impressed not only by their execution, but how well the students knew their own skill in going after a project that was equal parts ambitious and reasonable,” said Jeff Bayes, QuackHack organizer.
More than 100 college students from 6 states, 14 universities and 16 different majors participated in the hackathon.
“We didn’t really expect to compete against more experienced people, but we decided we might as well go for it for our own benefit,” Phipps said.
“We just wanted to go and have fun and try to make something,” Case agreed.
To create their game within the short time frame, the team divvied up the programming components of the project. In the end, their separate functions had to come together to make the game work.
“It really makes you appreciate thorough design and pseudocode and flowcharts,” said Phipps. Jennifer [Parham-Mocello], our CS 160 professor, always talks about design, design, design. You
really need to have a large-scale design in advance; otherwise you can end up way over your head or you end up spending the entire time trying to debug.”
The teamwork is also crucial. “We helped each other with our weaknesses and built upon our strengths,” Warren said.
Parham-Mocello, who teaches the introductory computer science class, was thrilled with the students’ success. “This drives home what we teach: design, how to think and how to work in teams. They’re utilizing the principles that industry wants to see,” she said. “It’s not just about banging out code. We’re teaching students the proper way to do things from the very beginning.”
The Technology Association of Oregon (TAO) sponsored an Education Roadshow at Oregon State on May 28 to help students tailor their education to match industry needs. Representatives from AKQA, Columbia Sportswear, Hewlett-Packard, Tripwire and Vadio answered questions about what to expect when entering the workforce and how best to prepare. The event drew 250 students which was beyond the expectations of Danny Dig, assistant professor of computer science, who facilitated and moderated the event.
Maria Powell, who attended the event, said, “Being able to get first hand advice from professionals in the industry is invaluable to me. It not only gives me ideas of what I would like my goals to be beyond college but it helps me to be pro-active about my future right now.” Powell is a senior in computer science who will be graduating this August.
Nicholas Nelson, came to the event with more experience than most students since he worked in industry before returning to school in 2012 to finish his degree. “Our industry operates at such a fast pace, things that seemed common place three years ago when I was still working are likely to have changed. I wanted to be aware of the latest and greatest, and this industry panel did not disappoint. The diversity of panelists provided an excellent glimpse into both the start-up world and the established giants of industry,” Nelson said.
To make the time with the panelists the most effective, Dig polled students ahead of time to find out what questions they most wanted answered. The top two questions were: What questions should a prospective candidate ask during an interview? What kind of coursework and/or research projects are valued by industry? All the questions and answers are available on the EECS website.
“The students loved the event and many commented that these kinds of events make them feel lucky to be at Oregon State. Several of them have continuing discussions with the panelists about jobs and interviewing,” Dig said.
The event fits with the mission of the TAO to grow the technology economy in the region by providing programs and initiatives that support industry promotion, advocacy, professional networks, and talent development.
Dig acknowledged the help of the panelists: Bryce Clemmer (Vadio), Andy Neville (Columbia Sportswear), Andy Doan (AKQA), David Whitlock (Tripwire), Shelly Reasoner (HP) who volunteered their time to answer questions; Tina Batten who helped organize the event; Kevin McGrath, instructor for Operating Systems who gave up a class period for the event; all the students who helped generate questions and took notes during the event; TAO, which started the Education Roadshow; and Chris Scaffidi, associate professor of computer science, who had the vision of bringing the Education Roadshow to Oregon State.
Students in the School of Electrical Engineering and Computer Science (EECS) won three of the four overall awards at the Engineering Expo 2015. Additionally, the Industry Advisory Board for EECS recognized six other outstanding projects.
Boeing Engineering Excellence Award
The Boeing Engineering Excellence Award distinguishes a project team that delivers a robust and innovative solution with a clear focus on enabling potential customers to excel in their markets and missions.
Winner: EyeRobot. Team: Amber Hartman, Benjamin Narin and Kai Ovesen.
This project aims to help people with ALS (Amyotrophic Lateral Sclerosis) or similar diseases in which people lose motor control. Using eye gaze, the Electrooculography (EOG) headset provides an emergency stop for those who cannot physically hit a button. The project is in collaboration with researchers at the Personal Robotics Lab at Oregon State University who are developing a wheelchair that can drive itself using way points set by eye-tracking equipment. The head set measures electric potential across the eyes from two sensors placed on the temples.

An Oregon State University team of computer science and electrical and computer engineering students earned third place at the Intel-Cornell Cup on May 1-2 at the Kennedy Space Center Visitor Complex in Cape Canaveral, Fla.
The purpose of the embedded design competition is to inspire student innovation. Entry into the event is competitive; only 22 teams from across the country were selected to attend. The chosen teams were provided with $1,500 in funding and the latest Intel Atom board which they incorporated into their project.
Auto Safe, the Oregon State team, designed a system to send information about car accidents to other cars in the area. The device includes sensors to detect crashes and rollovers, and a wireless mesh network to transmit information between vehicles. The device can be plugged in to any car 1996 or newer via the OBD II port. (See video below for a demonstration.)
The event was open to the public, so in addition to presenting to the judges, the team explained their project to crowds of elementary students who were visiting the Kennedy Space Center.
“Our project was really fun for the kids because they could drive the simulator. One girl, who had never played a driving game before, stayed for a really long time,” said Ashley Greenacre, senior in electrical and computer engineering.
Meeting students from other universities and seeing their projects was one of the best parts of the event for the team. Chris Harper, senior in electrical and computer engineering said, “We were all using the same hardware, so it was really interesting to see everyone’s different take on it.”
It was the first time Sam Quinn, senior in computer science, had participated in a competitive event. “It was eye-opening to see the troubles that go on behind the scenes,” he said. The team had to deal with last minute networking problems, but rather than be upset by it, Quinn said that he really enjoyed high pressure problem solving.
The hands-on experiences that the students receive by working as a team to design a product is why Kevin McGrath, computer science instructor and advisor to the team, recruits students to participate in the event every year. “There will always be challenges, and how you overcome those challenges dictates the kind of engineer you are,” he said.
In just 30 hours, Oregon State University students created wearable technology projects at HWeekend on April 10-12, sponsored by the School of Electrical Engineering and Computer Science. Thirty-five students spanning several areas of engineering formed seven teams and built projects that ranged from a remote controlled arm to a video game.
The event was organized by Don Heer, instructor in the School of Electrical Engineering and Computer Science, who wanted to provide students an event similar to a start-up weekend or app hackathon, but for hardware. It was the fourth event for Heer who values real-world experiences that augment the student’s classroom experiences.
To build their projects the students had a variety of components available to them including tiny computers, NVIDIA Jetsons, motion sensors and motors, and as access to 3D printers.
“It’s surprising how much this relates to my classwork, but also how much fun I had with it,” said Mark Andrews, student of electrical and computer engineering and math. It was the second HWeekend for Andrews.
About half of the students at the spring HWeekend had participated in one of the previous three HWeekend events that were sponsored by Eaton, Rockwell Collins and Micron.
Two projects: The Hand of Glory by Mark Andrews, Paul Lantow, and Conner Yates; and Go Go Gadget Claw by Tyler Gilbert, Ryan Green, Rattanai Sawaspanich, and Keaton Scheible are featured in videos below. The Go Go Gadget team won the Most Innovative award and tied for the Most Helpful award with the Mechanical Calf Assisting Device team.
Projects like a prosthetic hand and a spinning LED display were completed in just 30 hours at Oregon State University’s second hardware weekend (HWeekend) on October 18-19. It was a feat that amazed everyone involved including representatives from the sponsoring company, Rockwell Collins.
“I’m really impressed with the energy level and enthusiasm and the challenges that they took on. They were pretty big scope projects, and it was amazing what they got done in 30 hours,” said Bob Woods, director of engineering at Rockwell Collins, Heads-up Guidance System.
Instructor, Don Heer, came up with the idea of a hardware weekend based on start-up weekends that focus on software projects. Heer wanted something that would incorporate all branches of engineering to give students an opportunity to have the experience of developing a prototype device under time pressure while working in diverse teams.
That appealed to computer science student, Vedanth Narayanan, who was used to working on software development projects with other like-minded computer science students, but wanted to see what it was like to try and communicate across the different engineering disciplines. After 30 hours of work with no sleep, he was still gushing about the experience.
“It’s awesome to see it all come together knowing that it wasn’t just one group that did it. It was multiple different disciplines that came together,” he said.
Narayanan was part of the largest team of eight students who are majors in electrical, mechanical, manufacturing and industrial engineering in addition to computer science. Sean McGlothlin, a senior in computer science, came up with the idea for the project — an R/C car controlled by an Android app. It could have been an unwieldy number of students to work successfully, but they split into two main groups — mechanical and software — and had a designated leader for each. The team included Aaron Sprunger, a fifth year senior from industrial engineering with vast leadership experience who led the mechanical side. McGlothlin led the software team and the project design for the entire project.
“It was a great privilege to have my idea — something that was just a concept in my head — worked on by a team of very intelligent people, and in less than two days I was able to hold that concept in my hands. I’m really proud of our team,” McGlothlin said.
McGlothlin said the real value of the weekend was the chance to develop skills in project management and embedded programming. “I feel like I learned more in two days than I’ve learned in an entire term for some classes,” he said.
The two awards (Executioners and Helping Hands) both went to the team who built a force feedback prosthetic hand. The team hit all their goals including a sensor suite to give the user both tactile and visual feedback. For example, an LED would turn from green to red in the presence of heat. Team leader, Karl Payne overcame a major glitch when the 3D printer quit printing before the hand was complete. So, with 4 hours to go in the competition he laser cut the rest of the hand, pinning and gluing it into place. The team was also renowned for helping out the other teams, in particular Simon McFarlane was named as a stand-out contributor across the teams.
If there had been an award for humor it would have gone to the Q-bot team whose presentation of their ambitious project of a spy robot had everyone laughing. “It is very proficient in sneaking around corners and going completely astray in its direction and delivering a .2 frames per second video feed which is utterly out of color sync,” quipped Aravind Parasurama.
Throughout the competition representatives from Rockwell Collins were on hand to provide mentorship. Evan Marshall, an Oregon State alumnus and software engineer at Rockwell Collins admits to at first feeling obligated to come help out his alma matter, and was surprised at how much he enjoyed the experience, even sticking it out through the whole night.
“Seeing the impossible happen — that was fun. The people who were here brought all their own energy and that was contagious,” he said. He was impressed with the expertise of the students who knew more about their specialized area than he did, so he mostly helped facilitate discussions and motivate the students by letting them know from an outside perspective they were doing great things.
The sponsorship of Rockwell Collins made the entire weekend, including meals, free to the students. Heer was pleased with the success of weekend, which he plans to hold twice a year, the next one in January of 2015.
“I’m always amazed at the quality of our students and how, given the slightest opportunity, they will go the extra mile to do something innovative,” Heer said.

Oregon State University alumni Janice Levenhagen-Seeley and Jennifer Davidson returned to Corvallis last weekend to host a 2-day event to encourage high school girls to enter technology fields. Both graduates of the School of Electrical Engineering and Computer Science, Levenhagen-Seeley is the founder and executive director for ChickTech, a Portland-based non-profit, and Jennifer Davidson is the program manager.
Participants of the ChickTech event built robots, video games, smartphone applications, websites, light-up textiles, and 3-D printable projects like figurines or pendants. It was an eye-opening experience for many who said they had no idea what went on behind the technology they use every day.
That revelation is just what Levenhagen-Seeley was hoping for. She created the Portland-based non-profit organization in 2012 to foster a more inviting culture for women in technology, and in particular for opening the door of technology fields as a career option for high school girls.
“In high school I really enjoyed math but no teachers or career counselors ever thought to mention to me, ‘You should try this programing class,’ or ‘You should check out engineering as career,’” said Levenhagen-Seeley who majored in computer engineering.
ChickTech involves high school teachers by asking them to nominate female students in their classes who have the aptitude for careers in technology but have not sought out opportunities to learn more.
Phoenix Brooks from Veneta said she was nominated by her teacher at Triangle Lake Charter School and her principal encouraged her to take the opportunity. She chose the workshop on website development because she felt like no matter what career she went into, it would be useful.
“I had never really considered a career in web development, but I’ve always been interested in it and this workshop has given me a lot more insight. I’ve learned a lot,” Brooks said. “I’d definitely do it again.”
Haley Payne of West Albany High School and Audrey Hysell of Lebanon High School teamed up to create an underwater version of the Flappy Bird mobile app in which fish navigate hazards such as fish hooks, anemone and sharks.
“We haven’t yet got the fish to die when they hit something, but we’ll get there,” said Payne with confidence. By the end of the day, they were able to show off their finished app to visitors at who attended the Tech Show.
It is that kind of “win” that Levenhagen-Seeley wanted the high school girls to be able to experience and what motivated her to organize a longer event for the Corvallis chapter. ChickTech’s first event for Corvallis last year was a day-long workshop which was not enough time to create a finished project. Since many of the girls travel from as far away as Newport, the addition of an overnight stay in the dorms made the event possible but also added a new dimension.
“The overnight stay was a really exciting component because the girls were able to bond a lot more,” Levenhagen-Seeley said.
The event was made possible by volunteers from Oregon State, Garmin, Hewlett-Packard, and Intel. Funding was provided by OSU’s School of Electrical Engineering and Computer Science, OSU’s Women & Minorities in Engineering, Garmin, Tektronix, HP, Phase2, Kattare, and Korvis.
ChickTech has three chapters in Corvallis, Portland, and San Francisco, but is expanding nationwide to add 5 chapters next year, and 8 in 2016.
