Ethernet and USB On-the-Go peripherals, coupled with compact size, are the key features of two 68K/ColdFire families from Freescale Semiconductors. Though the chips are designed for applications like industrial control, home automation and environmental monitoring that require small size and low pricing, they still have 256 Kbytes of Flash. The two, 32-bit families run at 60 and 80 MHz, delivering 2.1 MIPS. One version offers a USB 2.0 full-speed Host/Device/On-The-Go Controller, while the other provides a10/100 Fast Ethernet Controller with Ethernet PHY. In volume quantities, the 3.3V lines list for $5.49 and $7.99.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
