Dear Reader: For our first annual Valentine’s special edition of Gadget Freak we pulled out some of our most precious Gadget Freaks from the Design News archives. Just click on the link to review Gadget Freaks that address affairs of the heart. Dick Neubert, Engineer and Gadget Freak editor
Avoiding Doggus Interrupt-Us Planning a romantic evening at home? Les designed a remote control door opener so you don’t have to manually let Fido out of his cage. The system consists of a clevis mounted to the shaft of a solenoid and the door latch of the cage. Get Build Instructions | Post a Comment
Extra long-lasting Dripless Candles A candlelight dinner? Relax and enjoy the lambent halos and silhouettes. With electronic flame flicker there's no hurry – the candles never burn down and they won't get wax on your tablecloth. But use real ones around the hot tub. Get Build Instructions | Post a Comment

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.
