I agree Taimoortariq. The razzle-dazzle of a gadget is always a factor. However, in the first round of voting, the winning gadget was the one that was the most helpful, an alarm mechanism for the disabled.
I agree, when it comes to competitions people are more fascinated by the alluring nature of the project. They naturally tend to side up with the project which is more dynamic and fascinating appearance wise. That is a major factor that is usually considered especially by the general crowd.
Good point, 78RPM. There are so many ways to judge Gadget Freak submissions: difficulty of the engineering, simplicity of design, practical application, usefulness. The first voting round was won -- I believe -- on the social contribution the gadget provided to someone who was disabled.
Amorris, I voted for the motorcycle ignition system for that reason. It required the most engineering talent, and the lesson on using quadrature encoders was instructive to many. It's not just clever and cutesy. It is a practical device that actually get things done.
I'd like to vote for the dishwasher idea, but the video lacks explanation. From what I gather the LED is motion activated, so it isn't flashing all the time. It also turns off when the internal temperature goes up (cleaning). It then turns green after cleaning and then goes back to red after the door is opened. Don't dishwashers already include this indicator?
My complaint is that the indicator turns red when the door is opened, but this does not imply the clean dishes were removed. In a familty situation the dishwasher is often used to store clean dishes and it is inly emptied when half of them have been taken out for use (or too many dirty ones pile up on the counter above). The light needs to flash green until it is manually reset to red by the owner, when the washer has been completely emptied.
I'm voting for the Harley! Even though I must ask "Why was a PIC used?"
Mailbox Concept is a nice idea, but the current system showed a lot of opportunity for simplifying. Looks like the volume of space for Mail was competing with the system itself, partially filling up the box. Lots of batteries will become AC current in practice, no doubt.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
