Product reliability is designed. It is produced and managed. －Qian Xuesen 1. Circuits Are Designed. Don’t Just Draw, Be a Designer. An electrolytic capacitor soldered next to a heat sink causes the related circuit parameters to drift, resulting in unstable machine parameters; the inconsistency in the color of green LEDs makes them look unattractive. Each … Read more
Since the advent of microcontrollers, controlling robots has become increasingly easier. However, before such excellent tools were available, how did engineers make robots move? Analog Computers 1 Before digital computers were invented, people built analog computers using vacuum tubes, capacitors, inductors, and resistors, which could perform many simple calculations and control tasks. An analog computer … Read more
