A laser cutter to do press-fit assembly with 3D from 2D, a sign cutter to plot in copper to do electromagnetics, a micron scale, numerically-controlled milling machine for precise structures, programming tools for less than a dollar, 100-nanosecond microcontrollers. It lets you work from microns and microseconds on up, and they exploded around the world.
有一台激光切割机，可以将2D的东西成型为3D的东西 符号切割机， 还有一个微测量器 一个数字监控的制表机 还有一些价格低于一美元的编程工具 100纳米秒的微控制器，从微米到更大的计量单位都可以 这些正在全世界迅速埋蔓延
