Here's a weather instrument - the Dodecahedral Barometer -
that can actually determine how tall you are by reading the barometric pressure
between your head and your feet. Mark Thoren
notes that his gadget was inspired by the release of some new electronic
products. The first is a Serta model 270 barometric pressure sensor that recently
came on the market. The sensor is inexpensive and accurate to the point of
being suitable for weather stations. The other items that make this gadget
possible are some new HP displays that make the gadget's readings visually
this Setra pressure sensor pricing starts at $1738.00 I wouldn't call that inexpensive.
What I would call inexpensive ($58) is the TI eZ420-Chronos Development tool which includes a MSP430 series micropower microprocessor in a watch case with Bluetooth link to your PC. Besides a built-in temperature sensor, a 3-axis accelerometer, it also includes a pressure sensor which can read the height of your head, right out of the box. Mind you it wouldn't be accurate enough for serious weather measurements of barometric pressure.
Imagine being able to illegally download a physical product the same way you can with music and videos. That’s basically what’s happening with 3D printing and digital manufacturing, with huge repercussions in the intellectual property domain.
Ford will be the first automaker to commercially use Alcoa's tough & fast Micromill aluminum alloy process and materials, debuting on several 2016 F-150 truck components. Alcoa will also license its Micromill process and materials technology to Danieli Group.
