是以，我在一個藍草樂隊中演奏小提琴。

轉承詞

情態副詞

Typically, we're amplified at our shows. Fiddle is one of the most difficult instruments to amplify.

通常情況下，我們的演出都有擴音器。小提琴是最難擴音的樂器之一。

通常情況下，你要麼使用一個話筒

Which is what I have here--a little clip-on microphone--and you can hear me talking through it or you use a pickup

這就是我這裡的東西--一個小夾子式麥克風--你可以通過它聽到我的講話，或者你用一個拾音器。

which is embedded here in the bridge. A microphone typically sounds kind of more like what the instrument actually sounds like in person.

這是在橋上嵌入的。麥克風的聲音通常更像樂器本人的實際聲音。

While a pickup sounds kind of more, I don't know, "tin canny."

而拾音器聽起來更像是，我不知道，"錫罐"。

But problem is that sometimes I don't want the sound to be coming out of them

但問題是，有時我不希望聲音從它們那裡發出來。

Sometimes I want to be able to tune my instrument, or talk to my bandmates without the entire audience hearing it.

有時，我希望能夠調整我的樂器，或與我的樂隊成員交談而不被整個觀眾聽到。

It's really easy to find mute pedals for pickups.

要找到拾音器的靜音踏板真的很容易。

It's a little bit harder to find mute pedals for microphones, but they do exist.

要找到麥克風的靜音踏板有點困難，但它們確實存在。

But as far as I can tell, there's really nothing out that you can buy that mutes both a microphone and a pickup together.

但就我所知，你真的沒有什麼東西可以買到，可以讓麥克風和拾音器一起靜音。

There are some really really expensive preamps that are like a thousand bucks that will do that also.

有一些非常非常昂貴的前置放大器，好像是一千塊錢，也能做到這一點。

But I didn't want to spend a thousand bucks just for a mute.

但我不想為了一個啞巴而花一千塊錢。

And, of course, probably somebody watching this will tell me right away that they know exactly how to find this

當然，可能有人看了這個會馬上告訴我，他們完全知道如何找到這個

but I couldn't find it after extensive searching so I decided to make one myself.

但我在廣泛搜索後沒有找到它，所以我決定自己做一個。

Alright, the parts are here. Let's do this.

好了，零件都在這裡。我們來做這個。

So, what do you need to make a dual-channel mute pedal for a mic and a pickup?

那麼，你需要什麼來製作一個用於麥克風和拾音器的雙通道靜音踏板？

Two guitar cable jacks, an input and output mic jack, a three channel switch, one channel for the mic, one for the pickup and one for an LED.

兩個吉他線插孔，一個輸入和輸出麥克風插孔，一個三通道開關，一個通道用於麥克風，一個用於拾音器，一個用於LED。

9-volt battery and battery connector, some small bolts, a box to put it all in, and the makerspace at your local library

9伏電池和電池連接器，一些小螺栓，一個可以將其全部放入的盒子，以及你當地圖書館的創客空間

which has plenty of wire, soldering irons, drill bits, and so on. All in all it's only about twenty or thirty bucks if you already

其中有大量的電線、電烙鐵、鑽頭等等。總而言之，它只有大約二十或三十美元，如果你已經

own the tools or can borrow them from friends or go to a makerspace

擁有工具，或從朋友那裡借來，或到創客空間去。

I started off by finding the wiring diagrams for mute switches.

我首先找到了靜音開關的接線圖。

I don't know much about circuits beyond what you learn in high school physics, so these circuits are very very simple.

除了在高中物理課上學到的知識外，我對電路瞭解不多，所以這些電路非常非常簡單。

The pickup is the easiest one since it has only two wires

拾音器是最容易的，因為它只有兩根線。

One in black carrying a fixed reference voltage

and the other in red carrying the signal from the pickup

另一個是紅色的，攜帶來自拾音器的信號。

by connecting these two wires together you stop the signal from reaching the

通過將這兩根線連接在一起，你可以阻止信號到達。

I tested this all out with alligator clip cables to make sure things worked and the pickup was successfully muted.

我用鱷魚夾電纜對這一切進行了測試，以確保事情順利進行，並且拾音器成功地被靜音了。

One with a fixed reference voltage and the other two carrying copies of the signal from the mic.

一個有固定的參考電壓，另外兩個攜帶來自麥克風的信號副本。

The copies are inverted relative to each other and are later combined in a clever way to help minimize interference from other nearby

這些副本相對於彼此而言是倒置的，隨後以一種巧妙的方式進行組合，以幫助最大限度地減少來自其他附近的干擾。

electronics. Anyway, because the copies of the signal are inverted if we connect the two signal wires together the signals interfere and don't reach the

電子技術。總之，由於信號的副本是倒置的，如果我們將兩根信號線連接在一起，信號就會受到干擾，不能到達

PA system, muting the microphone. I tested this out too just to make sure it was working test 1 test 2 test

擴音系統，使話筒靜音。我也測試了這一點，以確保它的工作，測試1測試2測試

1 test 2 test 1 test :and it worked. As a theoretical physicist,

1個測試2個測試1個測試:而且成功了。作為一個理論物理學家。

I'm constantly amazed when something actually works in real life the way you predict it should. Oh, yeah

當一些東西在現實生活中真的像你預測的那樣運作時，我不斷感到驚訝。哦，是的

And of course there has to be a nice red LED that lights up to show when the mute is on.

當然，還必須有一個漂亮的紅色LED燈，在靜音時亮起顯示。

The LED has a very simple circuit: just a 9-volt battery supplying power and a resistor so you don't blow out the LED. and

該LED的電路非常簡單：只有一節9伏電池供電和一個電阻，這樣你就不會把LED炸壞。 和

I tested this too, just to make sure, because I don't know what I'm doing.

我也測試了這個，只是為了確保，因為我不知道自己在做什麼。

The combination of that click together with the light going on is so satisfying. So now to put this all into the box,

咔嚓聲與燈光的結合是如此令人滿意。所以現在要把這一切放進盒子裡。

這是在沒有孔的情況下出現的。

So I spent entirely way too long measuring and re measuring to figure out exactly where each of the holes should be.

所以我花了太多的時間來測量和再測量，以弄清每個孔的確切位置。

I only had one box and I did not want to mess it up.

我只有一個盒子，我不想把它搞亂。

I learned that step drill bits like this one are good for drilling big holes and thin materials as long as you have enough space

我瞭解到，只要你有足夠的空間，像這樣的階梯鑽頭很適合鑽大孔和薄材料。

On the other side for the bit to go through without hitting stuff.

在另一側，讓鑽頭穿過而不至於撞到東西。

Oh, and this shiny plastic box is ugly and

哦，這個閃亮的塑料盒很難看，而且

scratches and smudges way too easily. A quick visit to the kitchen scouring pad gave it a sleek brushed look, though

刮痕和汙跡太容易了。在廚房裡用洗潔精刷了一下，就有了一個光滑的拉絲外觀，不過

it still scratches kind of easily. Then it was time to get rid of those alligator clips and properly solder the connections together.

它仍然很容易刮傷。然後，是時候擺脫那些鱷魚夾，正確地將連接處焊接起來。

This was my first real time soldering and I'm sure I broke all sorts of soldering rules.

這是我第一次真正意義上的焊接，我確信我打破了各種焊接規則。

But I tried to look things up online and stay organized with different colors of wire and make sure I put the necessary wires through

但我試著在網上查找資料，用不同顏色的電線保持有序，並確保我把必要的電線穿起來。

the necessary holes before soldering them. And the heat shrink tubing maybe isn't necessary, but it is incredibly satisfying to put on.

在焊接它們之前，要先打好必要的孔。而熱縮管也許不是必要的，但它的作用是令人難以置信的，讓人滿意。

Here's the LED circuit, soldered and still working and a little while later, here's the pickup being muted

這是LED電路，已焊接好，仍在工作，過了一會兒，這是拾音器被靜音的情況。

I soldered the microphone connections and could actually put the switch into the box and put the LED in and test that everything was still

我焊接了麥克風的連接，實際上可以把開關放進盒子裡，並把LED放進去，測試一切都還在。

working. And I'm delighted to say it works. All in all this took me around eight or nine hours to build

工作。我很高興地說，它是有效的。總的來說，這花了我大約八、九個小時來建造

including filming myself while building it and if I did anything differently it would be to get a metal box.

包括在建造它時拍攝自己，如果我做了什麼不同的事情，那就是買一個金屬盒子。

The plastic one is just a tad flimsy and still too easily scratched. So here's the finished product.

塑膠的只是有點脆弱，還是太容易被刮傷。所以這是完成的產品。

It has two inputs, either for my mic or my pickup or both and

它有兩個輸入，可以用於我的麥克風或我的拾音器，也可以用於兩者。

one button that I can push to mute both of them together. That's all I wanted.

我可以按一個按鈕，讓它們一起靜音。這就是我想要的一切。

I don't know why this doesn't exist, but I had to make it myself.

我不知道為什麼沒有這個東西，但我不得不自己做。

I am so pleased with this. I'm really excited.

我對這一點感到非常高興。我真的很興奮。

It's such a simple stupid little project.

這是一個如此簡單的愚蠢的小項目。

But I'm super excited that I made something that didn't exist or I couldn't find and it's exactly what I want,

但我超級興奮的是，我做了一些不存在或找不到的東西，而且這正是我想要的。

and that's what's so satisfying about it. I highly recommend that you try projects like this.

而這正是它令人滿意之處。我強烈建議你嘗試這樣的項目。

It's really satisfying--you learn stuff and you end up with a product that you're proud of and

這真的很令人滿意--你學到了東西，你最終得到了一個讓你感到自豪的產品，並且

that you're gonna use actually in your, you know, your hobby of playing fiddle in a bluegrass band.

你會在你的，你知道的，你的愛好是在藍草樂隊中演奏小提琴的時候實際使用。
