Only a few electronics principles can cause a gasp of amazement. Generally if you want to please a crowd, you have to push some serious voltage and get some arcs going. Another experiment, however, never fails to impress: the Seebeck Effect. For those who need a reminder, the Seebeck Effect allows you to convert temperature differences directly to electricity without any mechanical bits in-between.
Sean Hodgins, a student at McMaster University in Hamilton Ontario, felt like the impact that the Seebeck effect can have on people deserved making a cool way to s......
Some say the person who invented the second wheel never got the credit he/she deserved. Who rides on a single wheel after all?
Researchers at The University of Tokyo's Department of Mechano-Informatics have proven that if you put your mind to it, you can make a single wheel do a lot for you. Their quadrocopter wheel performs the trifecta of motion—flying, floating on water and rolling on land.
Called the Multi-field universal Wheel for Air-land (MUWA for sanity), it uses four variable-pitch propellers. Yes, unlike what you've seen until now, the propellers......
The first thought I had about iPhone 5S's fingerprint sensor was that it would nicely round out individual data scraped and hacked by government agencies. But I don't care much about that. Perhaps I should, considering news reports that indicate prevalence of act-before-you-think procedures. That's another conversation, however.
What if a hacker got hold of your fingerprint? We leave fingerprints everywhere, but they usually don't get collected for easy distribution or association with a lot of our personal data. Well, at least not outside the agencies we h......
