I was once very interested in those TI 802.15.4 SoCs, but those currently in production use an 8051 core and to do anything useful with them requires a heafy investment in development tools (eg IAR which costs 2-3k$). No thank you, ARM for me please.
I recommend the ZigBee protocol only when a design requires interoperability with other ZigBee devices, or when someone wants a ZigBee certification. For proprietary designs or basic wireless communications, modules that operate to the IEEE 802.15.4 standard will do a nice job without the software overhead ZigBee requires.
Using a 3D printer, CNC router, and existing powertrain components, a team of engineers is building an electric car from scratch on the floor of the International Manufacturing Technology Show in Chicago this week.
In November, a European space probe will try to land on the surface of a comet moving at about 84,000 mph and rotating with a period of 12.7 hours. Many factors make positioning the probe for the landing an engineering challenge.
NinjaFlex flexible 3D printing filament made from thermoplastic elastomers is available in a growing assortment of colors, most recently gold and silver. It's flexible and harder than you'd expect: around 85A (Shore A).
