By adding more on-chip memory and functionality to Hitachi Semiconductor's H8/300 series 8-bit microcontroller, engineers produced a new series of devices that are said to be capable of replacing 16-bit MCUs in cost-sensitive applications, such as print-head motor controllers. The H8/3318 model has a 60-KByte ROM to store complex programs and a 4-KByte RAM--the largest on-chip RAM of any 8-bit MCU--to handle the larger storage requirements of such programs. The company claims that design engineers will find the new 8-bit H8/3318 capable of doing the job of a 16-bit MCU or even 32-bit MCU in many applications. Such cost-sensitive applications include fast, precise motor control systems for printers and plotters. Hitachi Semiconductor (America) Inc., Product Code 4176.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
