  • So, I play fiddle in a bluegrass band.

    是以,我在一個藍草樂隊中演奏小提琴。

  • Even though it's an acoustic instrument

    儘管它是一種原聲樂器

  • 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。

  • Typically you either use a microphone

    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。

  • an LED and resistor,

    一個LED和電阻。

  • 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

    一個黑色的攜帶固定參考電壓

  • 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。

  • amplifier or PA system or whatever.

    放大器或PA系統或其他什麼。

  • 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。

  • So, onto the microphone

    是以,在話筒上

  • The mic has three wires

    麥克風有三條線

  • 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。

  • which came with no holes in it.

    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。

  • and finally

    以及最後

  • 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.
