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.
MIT students modified a 3D printer to enable it to print more than one object and print on top of existing printed objects. All of this was made possible by modifying a Solidoodle with a height measuring laser.
