[参赛]完成的DAC

参赛作品如下:

自制DAC一(CS8412CP+TDA1541+LT1057)

最终线路图如下:

CS8412的Format为M3=0、M2=0、M1=1、M0=0        (L/R I2S Compatible)
<img src="attachments/dvbbs/2005-1/2005122309679.gif" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-1/2005122309679.gif\');}" onmousewheel="return imgzoom(this);" alt="" />
制作本机使用的洞洞板
首先把电路规划为3部分
即DAC解码部分、运放输出部分、和电源部分
根据洞洞板的大小做如下图的大概规划
<img src="attachments/dvbbs/2005-1/20051223047656.gif" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-1/20051223047656.gif\');}" onmousewheel="return imgzoom(this);" alt="" />
然后制作了一张洞洞板的草稿图~
<img src="attachments/dvbbs/2005-1/20051223126833.gif" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-1/20051223126833.gif\');}" onmousewheel="return imgzoom(this);" alt="" />

续!

在上面根据电路图进行设计元件布局和走线
然后焊接元件

在焊接的时候我采用的是直接用焊锡来走线把洞洞连在一起(超级浪费焊锡的方法)
因为使用了IC插座
在安装时很方便 呵呵~
焊接完成后 先用数字表测量个各点是否连接正确 确认无误后通电
测试电压正常后
插上IC测试
以下是测试时的图片
视频拍的 不是很清晰
<img src="attachments/dvbbs/2005-1/20051223238408.gif" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-1/20051223238408.gif\');}" onmousewheel="return imgzoom(this);" alt="" />

一下是完成后拍的清晰度较高的图片


<img src="attachments/dvbbs/2005-1/20051223430149.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-1/20051223430149.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
<img src="attachments/dvbbs/2005-1/20051223515601.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-1/20051223515601.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

呵呵末尾付上咱和DAC的合影
证明东西是咱做D
(人难看。。希望不要成为扣分的焦点。。。)
<img src="" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-1/20051223849200.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

后感:
    这是本人第一次完整的制作DAC,感觉其实制作出DAC并没有想象中的那么困难(当然这是指做各能响的DAC),只要细心些都不

会出太大的问题。在制作本机的时候我也出了点白痴的问题。。比如说该接地的部分忘记了接地 导致电路发热等D级问题,还有忘记

插上运放而以为电路出了故障,白痴般的检查半天之类。本人并不是学习电子设计专业的能做到此也算对得起自己了~~呵呵~~重在参

与,请大家不要笑话哦~

最后贴张 DAC的临时机壳图~
因为没有数码相机没办法老上清晰的图片只能用视频代替了 请见谅!

用了报废的光驱盒子呵呵~~勉强使用了

两点惊讶,一是洞洞板也能做的如此漂亮,二是明兄竟然如此年轻。佩服佩服!

一般吧,真正想玩洞洞不能用这种垃圾万能板,同学们注意了。要玩就要买好的洞板,这种一焊就掉铜,十分痛苦。
看我做的,哈哈
