For those who love model trains,
here's a peek at the future - a solar-augmented monorail. Joe Kopacz and his
brother Justin created the monorail from scratch. Joe, a mechanical engineer at
Colorado State University, created the gadget for a school contest. The
monorail includes break regeneration and has solar panels to augment the battery.
The monorail is run off of an arduino uno, which controls the recharging and
other special features - including lights that come on when the monorail enters
I guess the future is now. This is certainly a long way from the trains I had as a kid. Even later on when a buddy of mine got into model trains for a while they were not like this. I have heard a lot about the arduino technology but have not tried my hand at it yet. The solar aspect of this is interesting as well since I am seriously considering some home improvements that would include some solar PV installations. Here in Florida any power sold back to the utility is at the same rate we get charged for it so it is a pretty attractive proposition once all the state and Federal incentives are added in.
I am just not so sure how a real solar train would work out.... :-)
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
