Build a Microphone plug

Unfortunately, the Zaurus doesn't have a microphone built-in. But you can build a very small microphone plug which fits into the earphone connector in the top right corner of the Zaurus. You only need a 3.5 mm plug (mono) and a very small microphone which is soldered directly onto the contacts of the plug and fits in its housing.

顶一下。

其实，这个麦克，还有其他的包括USB HOST线、电池，自制出来都没有太大问题。
但关键，就是怎么在做得效果好的同时外观还漂亮，能跟机器配得上，这就有一定难度了。

MIC也算有用，有时也需要录音什么的。
不过，我是做工程的，这个Microphone接口，配上合适的接口和软件，可以作为数字示波器用，这比较有意思。

呵呵，是很有意思，但是采样频率怎么办？几十K吧？能用的地方不多啊……

用在串行通讯上可以了。
工程上跟搞研究不一样，一般看看信号好不好，有没有，就可以了。
最便宜的手持示波器，单色的，采样也低，要1500左右。

找了一条手机用的3.5mm的我耳机和麦克风线，可以在z机上录音和播放。
需要找个在z机上看录音波形的软件，类似Audition，功能不需要那么强，就可以当示波器用了。

linux下面有不少类似Audition的软件，如：
zynaddsubfx - http://zynaddsubfx.sourceforge.net/

Is an amazing multichannel, realtime 'analogue' synthesiser with fx using an FLTK gui. Does CXX00 range, overclocked, have enuff processing umph to run this? I need to find out!

seq24 - http://www.filter24.org/seq24/

fantastic, slimline GTK MIDI sequencer

specimen - http://gazuga.net/

virtual sampler, GTK based

audacity - http://audacity.sourceforge.net/

但是都没有z机上编译成功的版本。

由于工作的关系，经常调试各种低速率的数据信号（RS232）和音频信号，主要是检查是否有信号和信号质量。在办公室都是做个探头，用计算机声卡来采集。
如果z机上有waveform viewer或者edition的软件，那出去做工程就方便很多了。

这是老问题，为什么要用小z？

1 重量轻，便于携带
2 电池使用时间长

我是工程的，调试个BA的端口得一个大楼上下跑，没空调，没电梯。带个便携在现在上海这高温下，恨不得把便携扔了。

小z现在用minicom来调试串口／485什么的，很爽。
还能当电筒用。

小z的minicom不好找，附上。
需要USB串口转换器，在卖USB网卡的柜台上一般都有卖，买之前测试先。把USB转换器接上C1000的USB Host Line，看系统信息，如果出现USB Serial Port，说明装载成功了。

直接从dsp中读数据，分析一下，写到文件里就可以了吧~~~~这种需求不需要图形界面，而且编程也很简单。真需要界面的话用python/ruby之类的写一个也不难。
