用硬盘音圈电机DIY摇摆显示钟

1、DIY基于51单片机的旋转LED数字电子钟(红外线遥控调时)2007-06-05 23:00   在网上看到不少老外做的各种旋转显示屏，非常，我也动手用洞洞板试做了一个类似的显示屏，结果感觉还不错。于是再接再励继续努力，将作品进一步改进，完善后制成如今这个样子。由于刚学51单片机，加上制作电路板软件也是从零开始，的确花了我不少的时间和精力。不过也就是在这艰难的独立制作中，真正学到了不少实在的东西。本项目的关键是如何解决高速旋转的电路板如何供电，如何调时的问题。我采用电机电刷的原理，将旋转轴钻空，通过一只插头将电源的从反面引到前面的电路板上，而这个旋转的插头又与固定

2、在背板上的两个铜片接触的。调时的问题有些困难，一是让电路板在旋转前与机相接，由电脑传送调时数据，这虽然可行但不方便。还有就是用遥控方法，但此方案在调试方面有很大的困难。显示方式上，我采用平衡式的两排，这除了在旋转时能较好的保持平衡外，主要能利用两边交替显示方式，比单排要快一倍。本装置不仅是一个时钟，它还可以动态显示汉字及图案，这就看如何发挥了。其具体制作过程如下：一。旋转电机的制作从制作成本与方便考虑，选用旧电脑用的大软驱上的直流无刷电机，只是对局部进行改造。          就是这种古董软驱

3、  软驱上的直流无刷电机   拆开后的电机                 仔细拆开直流电机，将带圆盘的铝轴从中开孔，让它刚好能插入一个插头。       将旋转轴加工成这样 装配好以后           按

4、拆开时的顺序，反序将轴安装直流电机上。电机装配完成后  用两片铜片做的电刷电刷装好后的侧面图  将电路板上较突出的元件改焊在反面，  电机的电源接法。  从电路板标注的符号看，“”为电源正，“”为电源负，“”与“”端分别与电源正相连匀可使电机运转      将一张旧唱片按电机座的位置开孔，而定位用的挡光板应根据电路板上感光组件的位置确定。        二。电路板的制作本制作品

5、用单片机控制，具体电原理图如下：               用Protel 99设计制作了电路板。      最后得到完成的作品。              遥控器用的是松下车载机的，只用了其中的六个键。

91、60; LED旋转屏原理浅说2008-01-22 11:16          如果你在网上用google搜索“POV led”一词（POV即persistancd of vision），会找到世界各地的各种LED 旋转屏的制作介绍。那些摇晃出的空中图案，漂浮在车轮上的动画，以及形态各异的时钟，一定给你留下深刻印象。看到这些千奇百怪、创意无限的电子作品，除了羡慕、敬佩、感叹外，你是否想过自己亲自动手也做一个，做一个属于你自己的LED旋转屏呢？其实，无论你看到的LED旋转屏如何神奇，如何复杂，其原理都一样，

92、也很简单，说白了就是一个晃动的流水灯。在51单片机最简系统的其中的一个端口P0接上8个LED，就是一个典型的流水灯实验电路。由于没有几个元件，说干就干，把所有元件焊在万能板上，不需花费多长时间，就可完成整个制作。下面是随便找一个流水灯的C51程序#include <reg51.h>void main(void)unsigned int i,ch;ch=0x01;while(1) for(i=500;i>0;i-); if(ch=0x00) ch=0x01; else ch=ch<<1; P0=ch; 将这程序编译下载到系统的单片机上，待LED灯光开始正常开跑后，我

93、们拿着它在手上来回晃动，你发现这光已经不是一条竖直线了，它已经变成了一条条斜线。你可以适当修改程序中的延时，让这一连串的斜线更漂亮些（宽和高基本一致），怎么样，我们的最简LED旋转屏就这样做成了。     高兴之余，发现这与我们的目标好象还有点遥远，我们并不需要这些斜线，怎样才能做出网上的那些大虾那样显示的各种各样的文字图案呢？接下来，我们还得想其它办法，换一下思路，将需要的图案数据一串存在数组中，运行时又将数据一串串读出来，驱动LED，这样就能看到我们想看到的图案了。这是用此思路编的流水灯C51程序#include <reg51.h>cod

94、e unsigned char led=0x01,0x02, 0x04,0x08,0x10,0x20,0x40,0x80;void main(void)unsigned int i,j;while(1) for(j=0;j<8;j+)P0=ledj; for(i=3000;i>0;i-); 运行看一下, 结果与我们的第一个程序效果是一样的，但这个程序的优势在于我们可以按我们的要求，改变数组中的数据来驱动端口上的LED，达到我们预期的显示效果。这可以说是流水灯的万能程序。这样我们迈出了第一步。再来看如何产生需要的图案。现在我们让LED显示数字12为例，我们先作一个表。 &#
