Universal box for flashing LED's to music
Alright, in this Instructable I will show you how to create a box for making any led flash to music.
The difficulty of this is a bit above average of understanding.
BUT, i will try and make this as easy as possible, so anyone can build it!
This box will be universal, and you can hook up any lighting to it (that uses DC-voltages of max 50V and 15A) and make it flash.
I will upload a picture of the wiring later on.
For now, i will explain every wire.http://p.videofy.me/v/1811736<--- Step 1: What do I need?
First of all, we need a set of tools.
A Dremel can be useful but is not necessary.
A Drill.
A Gluegun.
A soldering device :)
Cablestripper, and anything else you think you need. .. like good music.
1. Transistor. (NPN)
These come in all sizes and shapes, from my large one, to 35 nanometer.
2. Potentiometer.
I'm using a slider. One with a knob works just as fine.
3. On-Off switch.
Well, self-explanatory, but it's used to cut power.
4. A box.
To hide it all in and protect with.
5. LED's.
To test and party with!
6. Cables.
Because you can't get enough of wires. Step 2: Preparing the box.
First, we will prepare the box.
We need 6 holes for this particular design. It's possible with fewer, but it requires some homework :)
I put 4 on the short-sides and two on the longside.
The top two will be where you hook up the power.
The bottom two will be where you connect the LED's.
And the two on the side will be the signals going in. (Speaker wires from the stereo or amplifier)
After the holes are drilled, you either drill a hole on the lid for a potentiometer (knob version) or carve a longer hole for a kind like mine.
Aswell as a hole fitting for the on-off switch.
Make sure your potentiometer fits and slides without anything obscuring the way.
When done, glue it in place or use screws.Step 3: The transistor.
Now we are attaching some wires to this intruiging piece of IC.
But before i go into serious B,C,E - writing, here is some info on how it works.
-----
The transistor is like an amplifier.
It uses a small current to activate a bigger one.
When the small current gets bigger, the bigger one gets even bigger.
In this case, the small current is from my speaker-wires. When the base-lines roll it pushes more voltage through the wires, and this is what will make our "bigger" current to make the leds flash, or shine brighter.
This is why it's better to use a transistor for flashing with music, rather than just hooking it up straight to the speakercables.
I Measured my subwoofers Voltage-range, and it goes from 0V -> 12+V and if your LED's are made for 3V, you can imagine the poof they do. Since here we have a voltage-roof.
The transistor consists of three legs (can be more)
The Base
The Emitter
The Collector.
B,C,E.
The current wants to flow through from the Collector to the emitter, but it can't unless we have voltage on the base.
Imagine a switch on a wire. You press on it with your finger, you then control the current inside the wires to flow, or stop.
Now a transistor is smaller. So imagine your finger is replaced with a current. (this way we can make it smaller)
The current turns the switch on. But instead of just I/O, you can push harder, and get more flow, and vice verca :)
When you have it pressed at max, you will get what you have it hooked up to. 12V-car battery, or maybe a 3V-battery? (if you have it directly to your subwoofers lines, there aren't really a max)
---
Just typing this makes my head spin, so let's continue!
My transistors pins from left to right are, Base - Collector - Emitter.
So solder one wire to each pin, and two wires to the emitter (think of it as the pin that emits the power, this will be connected later to the negative pool of the battery, and signal.)
When you are done with the soldering, glue it to the inside of the box. Step 4: Wiring it all.
Here is where it gets VERY messy.
So follow these simple steps and you should make this work like a charm!1 First cable goes through the box from top left corner to the I/O switch (this is the cable you put on the + Pool on the battery)2 From the switch out the bottom left hole. Cut it here, this is where you connect the LED.3 The collectors wire you put through the bottom right hole. (Middle pin) This is where you connect the LED's other wire.4 Drag one wire from the emittor (right pin) out through the top right hole, this will be the negative pool on the battery or powersource.5 Drag the other wire out on the side of the box from the emittor. This will be the negative for the audiosource. (though it's AC "there is no negative")6 Final wire is from the base (left pin) this goes to the potentiometer.7 Then from the potentiometer out through the side hole.Dont forget to solder it all in place.
You can use hot-glue to fix your wires to the holes so they can last a few tugs and don't break. Step 5: Done!
Alright! You are done!
It looks .. like a crab, but it will get the work done! .. But yes, how does it work?
You are in luck, it's universal.
first you connect your LED's. (I'll use 12V-leds in this case) to the bottom wires.
Then you connect the powersource which in this case is max 12V DC.
Lastly connect the audiosource, and turn it on, crank up the volume!!!
Now you will notice it almost only shines brightly.
Mix with the potentiometer (Sensitivity stick) and watch it become more awesome :)
---
Other notes:
It IS POSSIBLE, to use a higher power-voltage to make lower-voltage LED's flash, but you will have to use the potentiometer carefully, so it stops enough power from the audiosource. (which controls the input voltage)
I have noticed that it's easier to make lower-voltage leds flash, than higher voltage.
If you, like me, use the speakerwires from the big stereo, it's not a problem with 12V LED's. since the audiowires spew enough voltage to make them flash, even too much when i crank the volume. 我不是专业翻译。。。所以。。。有些术语我表述不清楚 词汇量也少。。。你们将就看一下吧有英文能力好的朋友可以自行翻译一下
LED闪烁效果音乐播放盒
OK，在这里我会告诉你如何制作LED闪烁效果音乐播放盒。
我对此了解一点，这个难度高于我的水平。
但是我会努力让描述变得简单，让所有人都可以建立它！
这个盒子是通用的，你可以连接任何照明等设备，它使用50V直流和15A并且能闪光。
稍后我将上传布线图片。
现在，我解释所有的线。
步骤1：我需要什么东西？
首先，我需要一套工具。
一个“德雷梅尔”（这个具体是什么我不清楚 是在网上查的Dremel的意思。。。）这个并不是必须的
一个钻
一个Gluegun（不知道这个是什么。。。你们或许懂的。。。）
焊接设备
还有你喜欢的音乐。
1 晶体管NPN
这些元件大小和形状都不同，我用35纳米
2 电位器
我只用一个滑块和一个旋钮，作品效果一样好
3 切断开关
那么，我解释一下，它仅仅是用来切断电源的。（我觉得这个老外有点幼稚。。。或者说他很有童真~~当然我喜欢用后者描述他）
4 一个盒子
用于保护和隐藏所有东西
5 LED
测试和闪烁
6 电缆
因为你没有足够的线。
步骤2：准备中。
首先，我们准备盒子
我们需要6个这样设计的洞。
地步的两个链接LED
边上的2个链接信号（喇叭或放大器）
之后钻孔，你要不就钻在电位器盖孔（旋钮的那种）要不就像我这样刻一个长条
用来开关拟合
确保你的电位器位置合适没有遮盖
完成时，用螺丝固定
步骤3：晶体管
现在我们将电线连接集成电路
晶体管是一个放大器
它使用一个小电流来激活
当小电流越大，大的就更大
在这个情况下，小电流是从我喇叭线解出来的，电压通过导线，使我们大电流二极管闪光，或更亮
这就是为什么它使得一个晶体管闪烁，而不是仅仅让它亮
我衡量低音炮的电压范围，从0V-12V
该晶体管有三条腿（可以更多）
基地
发射器
集热器
目前希望通过集电极到发射级，但它不能，除非我们用基级电压
想象一下，在一个线路开关，你按它，用你的手指控制电流在导线流动或停止。
这就让我目瞪口呆，所以我们继续！
我的晶体管引脚从左到右分别是集电极=发射极=基级
因此要焊接每一根线到引脚，两线发射器
当你焊接完成后把它黏贴到盒子里面
步骤4：把这一些布线
这里很乱
所以我们要寻找简单的步骤，你应该认为这项任务有它的魅力所在
1 第一电缆通过左上角方块IO开关
2 从开关左下控连接你的LED
3 通过右下孔连接LED的其他线
4 找一根电线通过右上方的孔 这里是电池或电源的负极
5 从发射机侧面绕过其他线
6 最后的线通过左边的电位器
7 从电位器通过左侧的孔
别忘记固定所有的线路
你可以用热熔胶补孔
5 完成！
OK！你做到了！
虽然它的外表像个螃蟹 但他能工作！不过 他是如何工作的呢？
你是幸运的因为它是通用的
首先连接你的LED（这种情况下我使用12V的LED）
然后连接电源 最大支流12V
最后打开音量！！！
现在你回发现它的闪烁
混合的电位器可以使它变得更强大
其他注意事项“
如果要使用一个更高的电源电压驱动LED的闪烁 那你必须小心的是义兄电位器
我注意到 和高电压想比这很容易让低电压LED闪光

看了有点太简点了吧，这象初中生的DIY
原帖由 cardin6 于 2013-5-22 13:22 发表 https://bbs.eeworld.com.cn/images/common/back.gif占位翻译1 等待翻译 哈哈 懒惰一下
回复 4楼 soso 的帖子
翻译完了不过有些词汇和术语不理解。。。将就看吧。。。回复 板凳 ddllxxrr 的帖子
是很简单没什么难度对于我这种没接触过电路的人都可以轻松完成不过从这个小教程中我们或许可以得到点启发：就是如何让复杂的东西简单化或者说是让并不是很了解的人都能看懂；再就是细致的程度（包括文字、图片、视频等）；还有活泼的语言。
不难发现国外的教程或者DIY人发出来的东西图片质量普遍清晰的多，视频演示也很清楚，文字叙述方面的确有点童真 不过很生动活泼~~
你觉得呢？ 这照片拍的真高清啊，手痒痒，周末有时间咱也DIY一个:lol 楼主很有效率啊：）
图文结合会看的清楚些 现在对照着看 仍然有些晕 哈
不好意思 要求多了些 应用方面还是蛮可行的。。 楼主发帖辛苦了，谢谢分享！！！！！ Gluegun是热熔枪,就是用来打热熔胶的那个玩意儿. {:1_133:}这这这……
