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.
The company says it anticipates high-definition video for home security and other uses will be the next mature technology integrated into the IoT domain, hence the introduction of its MatrixCam devkit.
Siemens and Georgia Institute of Technology are partnering to address limitations in the current additive manufacturing design-to-production chain in an applied research project as part of the federally backed America Makes program.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
