I love stories where people make changes in someone else's project without thinking of or knowing of the damage they could do. I unplugged an extension cord that ran to a copier so I could move a desk to another area and then I was going to replug it. Harmless right.
Well someone else had already disconnected the copier and had a computer plugged in. I pulled the plug and heard one of the book keepers say, "Oh no. I just lost March." I was tempted to quickly reconnect before I was found out, but confessed and had to indure icy stares for a good week or so.
Growing up on a small farm in Eastern Oregon, I learned how to fix a lot of things with tools/supplies at hand (I have a pickup and baling wire story). It's served me VERY well in this career and in my hobbies.
On the southwest corner of the campus at Worcester Polytechnic Institute (Worcester, MA) stands a stone building used some time ago as a magnetics and electricity lab. It contains no magnetic materials. Read a short history and see a photo here: http://www.wpi.edu/about/tour/skull.html. The street-car line no longer exists. I cannot vouch for the veracity of stories about the Skull society and any "secret" ceremonies.
I heard a story about engineering students who created a wireless robot that would crawl through metal pipes. The robot would into the pipe, but at exactly the same point it would stop communicating. Turned out the pipe formed a nice waveguide and acted like a dead short for the RF, so communications ended abruptly. My memory is a bit hazy, so maybe some other waveguide effect caused loss of comms--I'm not a microwave guy.
Some cars are more reliable than others, but even the vehicles at the bottom of this year’s Consumer Reports reliability survey are vastly better than those of 20 years ago in the key areas of powertrain and hardware, experts said this week.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
While many larger companies are still reluctant to rely on wireless networks to transmit important information in industrial settings, there is an increasing acceptance rate of the newer, more robust wireless options that are now available.
