I recently bought a Bell Spinfit bike speedometer for $16 at Kmart, a store near my house that I usually loathe for being out of the most common items. The AG12 1.5 volt battery out of the box had about a day's worth of power left so I tried a few stores for a replacement. Best Buy, famous for untrained and unknowledgeable sales people, didn't have it and urged me to go to CVS, which had some batteries that looked close, but did not exactly match the AG12 designation. I later discovered AG12 is a Chinese battery number. A guy at CircuitCity at least had good advice - try RadioShack. In my experience, the sales people at CircuitCity are superior to Best Buy's. I don't go to Besy Buy much anymore.
Being the persistent SOB that I am, I decided to go back to Kmart and get some satisfaction. After all, it sold me the defective battery. The speedometer was installed and working so I was reluctant to put more time in to return it. It's a nifty item and Kmart has for $1 less than Amazon. The Kmart store manager (Kim?) gave me $4 to buy a new battery, a fair settlement. So I strutted down to Radio Shack 400 feet away and the sales person instantly knew that an AG12 was an Energizer 386, the one I refrained from taking a chance on at CVS. I paid $5 for it. So a couple of gallons of gas and an hours later and a buck poorer, I was up and running. I usually use Radio Shack for niggling purchases like this, but maybe should try some big ticket items there, too.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
