Undergraduate Researchers Win Big at “Energy Challenge” With New Turbine Converter

International Future Energy Challenge winners, Jonathan Baker and Christopher Hamilton created a low-cost wind turbine that transfers a maximum amount of energy to a battery. How did they do it? They contribute their success to time spent doing undergraduate research.

Baker, Hamilton, and two fellow electrical engineering majors spent over a year preparing their “low-cost wind turbine energy maximizer” for the International Future Energy Challenge in Australia last July.

The two-some invented a three-phase AC/DC converter (also known as “The Pegador” to its creators) to make the energy produced by wind turbines more efficient. The Pegador took home first prize.

After enjoying the success of placing first, Baker and Hamilton garnered success among engineering peers from universities worldwide.

Their participation in undergraduate research is what they claim to be the ultimate stepping-stone for future success within the scientific community and public-at-large.

“Going from book knowledge to tangibility experience has really accelerated my future career,” Baker said. “I’ve graduated with not only an honors degree, but an actual invention and experience.”

“Today’s engineering students want to make difference in the world … they want to make the world a better place through technological innovations that save lives and help clear the environment.” – Issa Batarseh, professor and director of the School of Electrical Engineering and Computer Science. Batarseh also oversaw the project.

There is no release date for the turbine at this time.


UT-Austin Students Collaborate With Indian Counterparts on Third World E-learning

Engineering Students at the University of Texas at Austin recently worked with students at a university in southwest India on the already well known One Laptop per Child program. Five Seniors in the Department of Electrical & Computer Engineering (ECE) at UT-Austin collaborated together in two teams with five students at Amrita University in developing a prototypical solar charger for the computer, along with power management software, and in developing a low bandwidth e-learning system for delivering lectures to students in remote areas. The e-learning system will continue to be worked on in the coming year by a new team, while students who participated in the program last year credit it with helping improve communication and teamwork skills.

The senior design sequence is designed to help ensure that students graduating with an ECE degree are adequately prepared to enter an international workforce and become part of teams working on complex projects. This two-semester sequence teaches students skills such as risk and project management and allows them to explore professional-grade tools for capturing their designs and supporting the collaboration. In addition to the multi-institutional option, senior design projects can also be multi-disciplinary, leading, for example, to teams that blend EE and mechanical engineering students.

During the pilot offering of the multi-institutional senior design option, five students at UT and five students at Amrita University in southwest India divided into two cross-institutional teams. Both teams targeted the One Laptop Per Child platform. One team developed the prototype for a solar charger with power management software. The other team developed the prototype of a low-bandwidth e-learning system designed to deliver lectures to remote locations in third-world countries. A new multi-institutional team will continue work on the e-learning system during the 2008-2009 academic year. A participant in the pilot offering reports, “This project taught me how to deal with an international team. Dealing with the cultural, lingual, and time differences made me more confident and improved my communication skills. We got to know the people in India and became a wonderful team with great spirit and enthusiasm.”


Dissecting an IP Phone “Magic Cable”

Originally posted to the ASEE internal Information Technology blog by Sean Stickle:

As discussed at lunch, I have long believed the Polycom Power-over-Ethernet cable to be a fiction: at best, a misunderstanding on the part of the sales agent; at worst, a ploy to make extra money off customer ignorance. So I decided to take apart one of the magic cables and see what mysteries it held. Unfortunately, the cables didn’t show up with the phones. So I dissected the next best thing: one of the power cables that was bundled with the phones.

Here are the interesting results of my investigation.

Warning: these pictures show graphic dismemberment of a relatively expensive power cable. No otters were harmed during the filming of this investigation.
