Useful modding - a spectrum analyzer + clock. We came across two 5x8 LED matrix, virtually occupying five-inch drive bay, and I decided to make a spectrum analyzer based on their sound.

通过51单片机串行转并行，扩展IO口，实现四个步进电动机的控制。(By 51 microcontroller serial to parallel IO expansion port, to achieve four stepper motor control.)

基于m16的温度控制系统，主要用ds18b20(failed to translate)
