問題在於，動手做本身是有趣的

and if you've got a really good idea,

you could probably do it.

你可能可以實現它

Now, there are different styles of making things.

現在，動手做有許多方法

And there's inventing,

The best kind of making things involves

動手做東西最好的方式

not just following directions from people

不只是遵從那些

who have done things before,

做過的人給的指示

but actually going out there,

更應該突破它

figuring out how to make something,

想想如何製做一樣東西

doing the design yourself,

自己設計

and then actually building it.

然後真的把它建造出來

Now, I don't have a lot of time,

現在，我沒有很多時間

but I want to get you started

不過我想要啟動

on your own invention project, maybe.

你們自己的發明計劃，可以的話

So what I'm going to do live and real-time

所以接著我要做的是一樣

and something that scares me, is,

會動的、即時的、嚇到我的東西

because it is live and real-time,

會動又是即時的

is I'm going to make an audio speaker

所以我要做的是一個擴音喇叭

out of stuff that I found in my kitchen

材料是我來紐約的前一晚

on the night before I came to New York.

在廚房找到的東西

Okay.

好

So what I've got here is a block of wood.

所以我找到的是一塊木頭

I've got some sand paper.

我有幾塊砂紙

I've got some pieces of notebook paper

然後有幾張筆記紙

folded up into a rough "Z" shape.

我把它摺成 Z 字形

I've got two magnets.

我有兩個磁鐵

And, I've got some wire.

還有一些漆包線

Now, this wire is the key part.

嗯，這些線是關鍵的部份

The four things that I need to make my own speaker is

要做喇叭 我須要的四樣東西是

a diaphragm,

振動板

a coil,

線圈

a support,

電源供應器

and a magnet.

還有一個磁鐵

So first thing's first.

所以重要的先做

Let's start doing it.

我們開始吧

What I need to do is wind a coil.

我現在要做的是捲線圈

And what I'm going to do is take this wire

我想做的是用這個漆包線

and wind an entire voice coil from it.

捲出喇叭線圈

Now, unfortunately that's going to take a really long time,

現在不幸的是，這會花很長的一段時間

and I don't have much time,

我沒那麼多時間

so I'm just going to give you the flavor of it.

所以我是要給你一些它的概念

I'm going to take 30 gauge magnet wire

我要做 30 口徑的電磁鐵

and I'm just going to wrap it tightly together,

我只是要把它緊緊地纏在一起

and I'm going to do about 150 turns

大約要在 3/4 吋的木桿上

on a 3/4 inch wooden dowel.

纏 150 圈

Now why would I do that?

為什麼我要這麼做？

Because I want to get my coil to have about 4 ohms of resistance.

因為我想要讓我的線圈 大約是 4 歐姆的電阻。

If you don't have enough resistance,

如果你沒有足夠的電阻

you can do something bad to your amplifier.

你可能會損害到你的音訊放大器

And then once that's done,

接著在完成以後

I'm going to glue it all together so it's nice and tight.

我要把它穩固地黏在一起

Now I don't nearly have 150 coils there

現在我還沒遠遠不到 150 圈

so I made one in advance

所以我事先做了一個

and I'm going to use that one.

我會用它來代替

So where is it? Here it is.

在哪呢？這裡

What I'm going to do is simply hot glue it

我要做的只是簡單地 用熱熔膠

to the back of this yogurt cup.

把它黏在優格杯的背後。

And I had to eat a lot of yogurt while I was experimenting,

我在做實驗的時候 可能要吃很多優格

so I feel like I've got all the calcium I need for a while.

所以我覺得我吸收的鈣 已經夠我撐一陣子了

Now, the next thing I'm going to do

現在，下一件事

is take these magnets and glue it in the center of this dot.

就是把這些磁鐵黏在這個點的中心

Hot glue, by the way,

附帶提一下，熱熔膠

a hot glue gun, it's the greatest maker toy you can possibly have.

熱熔膠槍，真是你拿得到 最偉大的製造者的玩具

I don't care what the 3-D prototype guys say,

那些 3-D 模型我不放在心上

I love my hot glue gun!

我愛我的熱熔膠槍！

What I'm going to do next

接著我要

is take these little "Z" stand-offs, see?

拿這個 Z 字的支架，有看到嗎？

And I'm going to put some glue there.

我要把它黏在那裡

Look how fast that bonds!

你看看它黏得多快！

My god, this is great stuff!

我的天，真是個好東西！

And I'm going to do that,

接著我要

and then I'm going to glue this.

我要黏這個

And I'm going to center that coil right over those magnets

然後我要把線圈對準中心

so it's just above it.

讓它就在磁鐵的上面

And now it's done.

完成了！

Now this needs to dry.

現在要等它乾

So you know how Martha Stewart would take the cake

所以你們都知道瑪莎．史都華（Martha Stewart） 會從烤箱

out of the oven, it's pre-made?

拿出蛋糕，那是事先做好的？

We're going to do that,

我們也要這麼做

So this is the one I made earlier today.

這些是在這之前我做好的

And it's the yogurt cup,

這是優格杯

the stand-offs,

支架

and everything else.

還有其它東西

Now you can experiment with different things.

In fact, I did.

事實上，我做了一些

I made one out of a coffee cup lid.

我用咖啡杯蓋做了一個

I made one out of a Tostito.

用 Tostito 脆片做了一個

The Tostito looks like a speaker, doesn't it?

你可以看 Tostito 就像是一個喇叭，對吧？

So, you can imagine how good that works.
