Step 4: Building the box

Now we've got the plates for the box, we need to put them together.

Before you go and glue parts together, make sure first they fit nicely onto each other. We need all parts to fit nicely.

1. After fitting the plates get the glue gun and glue the first 3 plates together. If you have some trouble holding the plates together before gluing, you can use some tape to hold them together. This way you can put the glue on more relaxed.

After gluing the 3 plates you should have something like photo 2

2. After the glue is dried, it's time to glue in the side plates. First place them and see if they fit nicely.
If not sand the sides a bit so everything fits nice together. Then glue them on their place.

The last (bottom) plate will not be attached yet. We need to put the whole circuit on the bottom plate later and then put it in place.

At this moment you should have something like photo 3 and 4.

LEDs r glowing very dim evn at the maximum volume. Any solution to bump the brightness to the maximum ? Thanks in advance <br>
<p>hello,<br>question is the music coming out from the speakers from the computer right not from a speaker integrated to the box,btw music is so cool!</p>
<p>Hey guys, I've been looking at this for a while and have some Ikea LED lights lying around at home, some RGB ones with a wired remote and have been testing them to see which parts control the positive and negative ones and opened up the splitter to see how it would be possible to have two TIP31 chips to control left and right but after looking into it, I struggle to see how to do that since the connectors to the LEDs have 4 pins each so I'm not sure where to go from this, I could simply only have left or right for all but why do it simply when it can be complicated ^^ Anyway, if anyone can help me out with this then thanks a lot and if the only possible thing to do is buy a new set of LEDs then so be it (but I'd rather not have to). Thanks a lot everyone :)</p>
<p>where is the circuit?</p>
I know this is a dumb question, but how do you keep from burning out the LEDs? Does it just evenly disperse? <br><br>Say i hooked the whole thing up to a cigarette lighter....<br>
Would substituting the individual leds with a led single color light strip, work?
Can i use my broken flat screen to do this?
<p>I made this(pics of the box will be posted later) instead I used 4 LED's (red,green,red,green) with a 12v 3.33a power supply. The reds are slightly brighter due to their lower forward voltage rating, compared to the greens. With this circuit, I tend to keep my volume low but higher on my headset. An with my HD Realtek Audio driver, I'm able to have multiple outputs, allowing me to plug my array in and not have to use a Y splitter. Again, I will soon post pics of my project. </p>
<p>Also, this is one of the best projects that I can say &quot;time well spent.&quot;</p>
Very awesome project. I did get it to successfully work; however, I also have the audio hooked up to an amp and the only way the LED will work is if the volume is maxed. I don't have any way to control the amp volume so it's really loud. Anyone have an idea how to up the signal to the LED's without increasing it to the amp? Thank you!
<p>someone plz tell me what kind of old material does have tip31c ?</p>
<p>u cant salvege that kind of part but there like 1.20$ at radio shack or</p><p><a href="http://www.amazon.com/gp/offer-listing/B0002ZPZYO/ref=dp_olp_new?ie=UTF8&condition=new" rel="nofollow">http://www.amazon.com/gp/offer-listing/B0002ZPZYO/...</a></p>
<p>copy cat u copyed this from the diy popular scinces book </p>
<p>I made it, I use 2 channels, four LEDs each Channels.</p><p>Here is the video</p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/b17zd35TTKs" width="500"></iframe></p>
<p>Very cool! Are you splitting left and right channels from the audio and then using two tip31 transitstors? Are you using a 24V power supply or is there a better way to fire up that many lights?</p>
<p>Yes I am splitting them L&amp;R with 12V powersupply, you can try two parallel the additional LED that you want as long as your power source can support it.</p>
<p>Hey my LED's have an earth in the middle of the + and - ... how do I earth them? I got this working years ago but trying to do it properly now but the lights I got have 3 conections.</p>
<p>Hi man this visualizer is amazing, but regarding the headset cable which is 3.5 jack I already cut it off but i have 4 wires one of them is red, is this red wire needed?</p><p>And is there any other components required like resistors for example? (like the diagram below)</p>
<p>someone plz tell me what kind of old material does have tip31c ?</p>
<p>thanks..can i connect the circuit in 230 volt ac by using ac to dc circuit.....? pls give me the ac to dc circuit.. my email:gokulindianur8@gmail.com</p>
<p>How to connect the phone? If we connect the phone through the audio jack, then how are the phone speakers going to work?</p><p> Please help asap.</p>
<p>I think it only works with external speakers... you will also need a jack split then...</p>
<p>does this project require a pcb layout?</p>
<p>hi, I just made this and burnd 4 of 7 LEDs. I used 2 tip31c transitores and a12v 500ma power suply. Wat did i do wrong? Love the project!</p>
<p>hi, if you find our led strip ,make this kinds of light will become easy ,check our web:www.lslledlight.com for led strip and module ,try it ,it is wonderful to you</p><p>by the way ,you design is so great!!</p>
<p>this is awesome, I want to do this without audio input, instead use a microphone, please someone help.</p>
<p>All you should need to do is simply build a small audio amplifier circuit (like the one attached) and connect your microphone to the IN of the amplifier, and the out of the amplifier to the base of the TIP31.<br>Connect all grounds together and you should be golden.</p>
<p>Why do the LED's not need a current limiting resistor?</p>
<p> <br> <br>Wow what a Great <br> Information about World Day its very nice informative post. thanks for the <br> post. </p><p><a href="http://www.monacopropertylistings.com" rel="nofollow">appartamenti a monaco</a></p>
<p>2 VERY IMPORTANT details left out in the directions that will make or break this project. I signed up just to post this and let others no.</p><p>1. &quot;Any wires&quot; will not do. The thinner the better. This will be absolutely impossible to do with thick wire because of detail # 2.</p><p>2. The wires CANNOT TOUCH EACH OTHER on the tip31, NOR CAN THEY TOUCH ANY OTHER LEG on the tip31, NOT EVEN A LITTLE BIT.</p><p>For example, the negative leg on the last LED light is to connect to the middle leg of the tip31. That wire CANNOT touch the left or right legs or any other wires, not even a tiny hair's-width strand of copper can touch anything else.</p><p>If they touch another wire/leg, you'll notice it will complete the circuit and turn all the lights on and stay solid. When everything is connected correctly, the lights will stay off until the music plays. It took me days to figure this out.</p>
it doesnt work with samsung phones what can i do
<p>One improvement would be to add a speaker amplifier alongside this and have the device put out some audio as well.</p><p>&lt;img src=&quot;http://www.deeptronic.com/wp-content/uploads/2014/02/small-amplifier-3-transistor-design.gif&quot;&gt;</p><p>This is a simple transistor circuit that works decently. If you want quality sound order an OP-AMP and use that (make sure it's 12V compatible).</p><p>Thanks for sharing!</p><p>JesusG33k</p>
<p>they spark together, no frequencies at all..but great job man... i think this one is better..</p><p>Souce : youtube</p><p>https://www.youtube.com/watch?v=Yd3hzYAJzOo</p>
<p>We made our first one of these, but are planning to make some changes. We used the super bright blue LEDs our local electronics shop carried, but they only have a 20 degree viewing angle. We sanded one of them to try to create the diffusion effect, but it just made the LED very dim. I just ordered some new LEDs from here: </p><p><a href="http://lighthouseleds.com/5mm-diffused-flat-top-led-blue-ultra-bright.html" rel="nofollow">http://lighthouseleds.com/5mm-diffused-flat-top-le...</a></p><p>and very interested to see the difference. Also, the info is here in the article, but I still didn't focus on it. We put 6 LEDs in our box like the video above, but it didn't work at all. After some confusing diddling, we finally figured out that we needed a bigger power supply. I found a 24V power supply on Amazon for about $8.</p>
Please tell me the exact number of the transistor the shopkeeper gave me tip31co.
<p>as long as it is TIP31. some had C and A but they work fine.</p>
<p>I'm testing my circuit on a breadboard (just like your linked video). I can't get the LED to respond to the music, it lights up as soon as I plug it into anything, music or not. It stays solid and won't respond to the audio signal. Know what I'm doing wrong?</p>
<p>Check your connection or repeat what you did. It happened to me. I even burned 10 LEDs.</p>
I'm so doing this, but I was wondering. Is there a way to sequence other lights to the individual parts of the tune? Like you have lights for the beats, but what if I want to add lights for the bass, and other?
<p>I am doing something similar! Filters! Look up low, band, and high pass filter designs and split the audio signal to run through each one respectively. Now you have signal for bass notes, mid ranges, and high frequencies. I have a tentative schematic as well. </p>
Very cool. Thank you. ^.^
Hey! Just ordered the components, so exited. I wondered of you could wire the leds up in a pararell connection and not a serial? So that you could use much more lights
<p>I didn't design it, but yes parallel would work and you could also use a lower voltage as well</p>
<p>Do you know if you can use speaker outputs from a receiver instead of the headphone jack? My receiver has A and B outputs, B for extra speakers. Would it be too much power? It is a Technics SA-DX1050. That way I wouldn't have to split the audio and I don't think I can play the speakers and headphones at the same time.</p>
My led are not reacting to audio cable . led are blinking countinously.
i have done everything you did except i cut the adapter cord and attached it to the led and tip35, everything works perfectly except when i plug it in i cannot hear music coming from my computer or phone or anything. what am i doing wrong? <br> <br>
Please tell me the exact number of the Transistor use
<p>Haha, it's amazing, thank you!</p>
<p>How do you get the cloudy look on the plexiglass? With sanding?</p>
