I agree AnadY, the most practical gadget here is the call for assistance. It serves an important need. The other three gadgets have value and they're all impressive as homemade products, but the call of assistance was created to improve someone's life. That said, the crock pot was also developed to improve someone's life. The bike proves out the ability to manage fluids, and the camera is nothing but amazing in the creation of its own parts.
Okay, now this is a difficult task. All these creations are freakish. That said, if I absolutely had to make a decision, this would be my least start from the least freakish to the absolute gadget freak in this group; A gadget's call for assistance, the analog camera from 3D parts, the programmable crock pot and Mr shock with his bike. But that's just me.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
