The Young Engineers Guide To University Capstone Projects

November 26, 2019 by Lewin Day 8 Comments

Engineering degrees are as wide and varied as the potential careers on offer out in the real world. There’s plenty of maths to learn, and a cavalcade of tough topics, from thermodynamics to fluid mechanics. However, the real challenge is the capstone project. Generally taking place in the senior year of a four-year degree, it’s a chance for students to apply everything they’ve learned on a real-world engineering project.

Known for endless late nights and the gruelling effort required, it’s an challenge that is revered beforehand, and boasted about after the fact. During the project, everyone is usually far too busy to talk about it. My experience was very much along these lines, when I undertook the Submarine That Can Fly project back in 2012. The project taught me a lot about engineering, in a way that solving problems out of textbooks never could. What follows are some of the lessons I picked up along the way.

The Young Engineers Guide To Career Planning

October 28, 2019 by Lewin Day 41 Comments

It’s often said that engineers aren’t born, they’re made. Or more accurately, taught, tested, and accredited by universities. If you’re in high school, you’re probably starting to think about potential career paths and may be considering an engineering degree. A lot of work goes into a good college application, and it might seem like the hardest part is getting in. However, if your end goal is to get yourself a great engineering job at the end of your studies, it pays to have your head up from day 1!

I Just Need A Degree, Right?

Back in my freshman days, there was a saying that was popular on campus, particularly with those studying STEM topics. “Ps get degrees.” Your college’s grading system might use different letters, but the basic gist was that a pass mark was all that was required to get your piece of paper at the end of your four years. While this is technically true, it’s only really a useful ethos if your aim is to simply get a degree. If your goal is to use that degree to score yourself a plum job in your field, it would be unwise to follow this credo.

This attitude will net you plenty of wonderful memories at the bar, but it will dent your chances of landing a solid job upon graduation. All in moderation!

The reality of the modern job market is that it’s highly competitive. Recruiters can receive hundreds of applications for a single job, meaning the vast majority of applicants don’t even make it to the interview stage. To trim down the pile, various criteria are used to pick out the ideal candidates. An easy way to do this is to sort by grades. Having a low GPA can therefore see your application relegated to the trashcan, before you even get a chance to impress anyone with your carefully honed skills.

A Professional-Level Desk In A Dorm

September 13, 2019 by Bryan Cockfield 9 Comments

Heading off to college comes with its own set of challenges. Harder course material, living away from home for the first time, and dealing with roommates are common hurdles to overcome, but an oft-overlooked issue is the poor quality dorm room desks. For a place that a student is expected to spend a majority of their study time, colleges and universities don’t often provide inspiring areas in the dorm rooms for this task. With a few tools and some time, though, anyone suffering in a dorm can have a much better place to work.

This desk build comes to us from reddit user [lucas_talbert] and is noteworthy for using simple tools and materials to transform the standard, boring desk in a way which won’t upset the facilities manager in charge of the dorm furniture. The backer is a piece of plywood which was covered in bamboo flooring. It was screwed into the back of the desk and secured with L-brackets. A piece of 1×4 was attached around the edges to help hide the LED lights and cables as well.

We like this build for its impressive transformation of an otherwise drab dorm room into a place that most of us wouldn’t mind having as our main workstation, even beyond college. It also uses common materials and is easily removable, both of which are perks when living as a student. The one thing it doesn’t have, though, is the ability to exercise when using it.

College Project Nets 360 Degree POV Display

July 25, 2019 by Lewin Day 14 Comments

Senior college projects are the culmination of years of theoretical learning finally put into practice. For many students they are their first experience of doing some proper, real world engineering. [Melangeaddict] chose to take on a persistence of vision display for his final project, and learned plenty along the way.

The display consists of a row of 48 RGB LEDs mounted on an arm capable of rotating a full 360 degrees, with a simple paper diffuser. This arm is spun up by a belt drive from an electric motor at significant rotational speed, so getting close to this machine is quite inadvisable. Thanks to quality bearings and a careful build, rotating resistance is minimal. An infrared LED is mounted on the frame, and the light picked up by a photodiode on the rotating arm, allowing the images to remain fixed in space without drifting over time. Images can be loaded to the display wirelessly over a Bluetooth interface, which was quite advanced for a DIY project in 2011.

We’re a fan of the 360 degree approach to POV displays, and with the right rotational speed and fast data rates, it would be possible to get some seriously high resolution out of the device. Just be careful not to stick your hands in the mechanism.

There’s a deep well to explore when it comes to POV displays, from three-dimensional builds to vibrating flexible setups. Video after the break.

2019 Cornell Cup Winners Include Autonomous Boat, Flapping UAV, And Leaping Rover

May 15, 2019 by Tom Nardi 5 Comments

For college-aged engineers and designers, finding a problem they’re truly passionate about early on could very well set the trajectory for an entire career. This is precisely the goal of the Cornell Cup, a competition that tasks applicants with solving a real-world problem in a unique and interesting way. From what we saw this is definitely working, as teams showed up with ornithopter-based quadcopters, robotic dinghies, forest fire sniffers, and high-jumping rovers.

With such an open ended approach, individual entries have a tendency to vary wildly, running the gamut from autonomous vehicles to assistive technology. No team feels pressured to pursue a project they aren’t truly invested in, and everyone’s the better for it.

Given such lofty goals, Hackaday was proud to sponsor the 2019 Cornell Cup. Especially as it so closely aligns with the product design focus of this year’s Hackaday Prize. Designing something which solves a real-world problem is definitely part of the formula when the goal is to reach large scale production. And after seeing the entries first-hand during the Finals at Kennedy Space Center, we think every one of them would be a fantastic entry into the Hackaday Prize.

I don’t envy the judges who ultimately had to narrow it down to just a few teams to take home their share of the nearly $20,000 awarded. Join me after the break for a closer look at the projects that ended up coming out on top.

Back To School Online

November 10, 2018 by Al Williams 6 Comments

In 1961, FCC Commissioner [Newt Minow] famously described TV as a “vast wasteland.” But TV can do great things; educational programming, news coverage, and great performances do appear, just not all that often. You can draw the same parallels to the Internet. Sure, it’s mostly cat pictures, snarky comments, and posts of what your friends had for dinner. But it can also be a powerful tool, especially for education. Recently, top-name schools and other institutions have posted courses online for everything from Python to Quantum Mechanics to Dutch. The problems are finding these classes and figuring out which ones are gems and which are duds. A site called Class-Central aims to solve these problems.

The site aggregates class descriptions from a variety of sources like edX, Coursea, and more. Users can rate the classes. Many of these courses are free to take. The recent trend is to offer the content for free, but charge for people who want an assessment, such as a certificate of completion or even a full-blown degree. Even then, the cost is typically far less than traditional college costs.

There’s also news about courses. For example, a recent post highlighted that edX now offers nine online master’s degrees in conjunction with major schools. A computer science masters from the University of Texas, for example, runs about $10,000. A Georgia Tech cybersecurity masters degree costs even less. There are another seven not ready yet, including one for electrical engineering.

Senior Design Project Serves Infinite Drinks

April 26, 2015 by Mike Szczys 6 Comments

If you’re creative, you can make your passion projects count for college credit. Somehow [InfinityTable] managed to use this infinity bartender build called BarT as a senior design project.

There’s a lot going on here, starting with the cabinet which is 30″x30″ and has some custom mirrored glass necessary because of a square cut-out in the middle of the front pane. The two mirrors face each other, with a strip of LEDs in between which accounts for the “infinity” part of the build. This is popular but usually it’s usually just the mirror and lights. In this case that special cut-out is a cubby for a glass. Place it in there and the rest of the build will mix you up a tasty beverage.

There is a second chamber in the enclosure behind the rear mirror. This houses the components that mix up the drinks. Raw materials are dispensed from 1.25L plastic bottles. The extra special part of the build is that since it is a senior project, all the driving circuitry uses roll-your-own boards.
