[参赛]完成的DAC

明9002

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）

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="" />

小钳子

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！

xiwei

虚心学习啊

gxnnzyz

收藏一下，试一试

连环腿

可否给上个详细电路图，想做

穷光胆艺

我也想做一个

juaninito

老弟很厉害啊，有条件的时候，可能你是中国的钢铁侠

仁客

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

牛人不少，厉害
