自制计时器，构造简单

这个要加油……能支持的只能是帮助选择加工原料了

<P>偶然看到这个资料，转贴如下：</P>
<P>&nbsp;</P>
<P>In official competitions, people have to put their hands on a pad before and after solving the cube. That's what starts and stops the timer. The official timing device is the <A href="http://speedstacks.com/"><FONT color=#0000ff>Stackmat</FONT></A>. I had to find a similar tool in order to get used to it and compare my times to others' times.<BR><BR>If you've got an old flat USB game pad you don't use, building a BurgerMat is quite inexpensive (I bought a new one for 10 euros). Remove the screws and get its electronic guts, that's all you need. Install it between 2 slices of bread. You want the two buttons under your hands, so you'll have to prolongate buttons 5 and 6.<BR> </P>
<P>&nbsp;</P>
<P>Plug it to your computer, write a small piece of code, and you'll have a very nice and cheap device that automatically computes averages and more (download a Java prototype source <A href="http://grrroux.free.fr/workshop/burger.zip"><FONT color=#0000ff>here</FONT></A>). By the way, this pad is much more sensitive than the ones I tried at the French championships. You'll find a video showing it in action somewhere on this site.<BR><BR> </P>
<P>&nbsp;</P>
<P>大致意思：</P>
<P>&nbsp;</P>
<P>官方比赛中，选手用双手触碰控制计时器的启动停止，而计时器则使用 Stackmat，但是作者找到了一种制作相似工具的方法。</P>
<P>整体思路是找一个旧的USB游戏手柄<FONT color=lime>（前提是废弃并且按键依然有效）</FONT>来做一个计时器<FONT color=lime>(Burgermat，不知道怎么翻才传神)</FONT>，首先是拆开并且拿出电子装置，就是所有需要的元件。<FONT color=lime>（晕，说得这么含糊……大约是把按键开关和导电橡胶等等拆出来，原文没给图，我觉得大概是按键那部分，我正好有一个断了按键冒的USB手柄没舍得扔，汗，楼主在北京的话我就直接送你了）</FONT>把按键放在两个面包片之间<FONT color=lime>（汗，面包片？冬天还好，夏天发霉了怎么办……）</FONT>，由于需要两个按键控制，所以安装的时候要延长按键5和6的导线<FONT color=lime>（思维很严谨，这也要提一句，不明白的是，为什么是5和6……）</FONT></P>
<P>&nbsp;</P>
<P>连接电脑，写一段小代码，这样就会有一个非常便宜并且扩展性很强的装置了，此处下载源码<FONT color=lime>（真不敢相信这么强大的东东是用面包做的，下次找些烤馒头片来……味道可能会比面包好些吧）</FONT>。这个计时器比作者在法国锦标赛<FONT color=lime>（牛人一只？）</FONT>上用过的计时器都灵敏<FONT color=lime>（面包的缘故？）</FONT></P>

<P><FONT color=lime>(本人不懂编程，属菜鸟一个，添加的文字仅供娱乐，如果你觉得也有价值，我真的感激涕零)</FONT></P>
