its pretty simple, you run speaker wire to the LEDs through a mixer to make certain lights light up for certain frequencies to simulate the different instruments. the current from the speaker wire will make the lights pule to the different sound.
@nathantinnion LEDs typically need 1.6 volts to get them to light up and the can typically only handle about 20mA (.02 amps) max. If you have a 12V supply and you need 1.6 V to light the LED you still have another 10.4 volts to deal with. You need to insure that you put a resistor in line with the bulb to reduce the current drawl available to the bulb. No resistor POP! 12 V - 1.6V = 10.4 Volts. R=V/I Therefore, R= 10.4 volts/0.02 amps = 520 Ohms. ECELab used a 1K.
I love the interference you recognize when this one sound gets louder and louder, I guess it is from the leds that goes with the frequency and it changes slightly with it, Or, well, fascinating.^^ Hey, could you put some links to the circuits into your description?
@Trace314 sweet. i have done a very basic circuit and it works but cant seem to get low pass filters etc to work with it. blown alot of leds but good fun so far.
Hey I am currently working on a electronics project and I really liked what you did hear. So did you design this your self? Also was the a program that you use to sync the music or does it act as a equalizer?
Nice vid.You gave me the idea and i just had to build myself the same thing.Didnt use bottles tough.I made this kind of fake led neons. Looks awesome only thing bothering on your project are the wires...I love clean look :)
Try using silver tape, or reflective tape on the inside of the top, to shine it downwards into the water.electrically, i couldn't tell you. did you use a type of capacitor/resistor combo to create a passive crossover? for each light?
very nice project, really cool effect. Can you upload diagram or tutorial. How do you make lights blinks in different times ?? you do that with frecuency separation ? Thanks in advance
Any chance I could see a schematic? From what I could see at the end the circuit looks simpler than what I could come up with, and I like simple. Awesome with the highlighter liquid, looks cool.
hey mike nice circuit noticed that you have used an adder circuit... but i jus wanted to know what value of Vdd for the op amp that u have given pls reply thanks great stuff ...
mike6789k Hello! I know this video is very old, but I'm also doing a similar project. What are the cutoff frequencies you used for the bass and treble? Also, did you use any special techniques to eliminate sound in the circuit? Why did you use amplification with a BJT rather than the op amp itself? Thanks!
@mike6789k that you include the formulas for calculating the R/C values based on the frequencies, because they aren't that easy to find (took me several hours of searching, and reading a electronics textbook to find them.) O, and very last thing, I don't think a detailed guide on placing the components is needed, as the schematic is pretty explaining for that, but the component values, and model numbers for some stuff (transistors, op-amps...) are needed for the majority of people begging for it
Nice. I did something similar to this myself, but I only did 2 frequencies because i found that the bandpassed LED seemed to always be on for music that wasn't techno. Since I can't see the model numbers or specifically what you're using, I'll take a guess. OP Amps configured in High pass, Low Pass, and a band pass configuration with what looks like a "preamp" op amp for gain? It's what I did lol. Nice work though :)
Awesome effect, I've actually been working a project like this for my motorcycle. I was wondering if you knew of a website with a schematic for that or something similar?
@cunje01 cool! you got the low pass filter down great, but i suggest improving the response of the high pass, looks great, i'm sure it's a hit at your frat parties! :)
Mike - Hopefully you are still checking this. I am working on a large project for my daughters dance comp. group. I already have setup a 72" diameter revolving earth that can be remote activate. Now I am working on LEDs to match the music. I have been working with the schem. you laid out - Thanks! I thought I would start out with basic freq. and then build off. I got the high pass to work but the low (on all the time) and band (not on) have issues. Could we discuss through email?
@mike6789k Thank you so much. i started researching how to make something like that, and looking to find the formulas, and instructions on how to make a low/band/high pass filter. i was planning on making it soon... as soon as i stopped procrastinating. One problem i had, however, was that i'm not sure about the schematics you had given, as they were quite the same as the ones i found while researching them. Are they, in order from top, to bottom a High pass, Low pass, and Band pass filter? Also
Let me guess: Active crossover circuit with LEDs for separate frequency ranges, so blue for bas, red for medium and then green treeble? That's simply awesome!! I'm looking for good schematics to make this for my PC's lighting, but only bass and treeble, so the red fans for bass and case's white for treeble. Do you have the schematics? I thing I'll manage the rest (can be a web link).
@Mike6789k Hehehe, i saw you post about "if you want to pay $40 for all the components that you can buy individually for under $10 then be my guest!" i think some would pay... even a lot. Also, what else did you put in the bottles? Green is highlighter fluid, I'm guessing blue is just tonic water, and the red is what?
Oh okay. Yeah I've been looking up alot about filters and discovered RC filters is what i need to be looking into. Now did you build those into that circuit you have there??? My deal is reading the schematics that have loops in them. I just don't quite understand how the voltage and current travel throig
Travel throughout the circuit as a whole... Its got so,ethingthingmto do with some equation thats set equal to zero... Butnyeah RC filters! Did you build them yourself into the cicuit?
Oh the fluorescent dyes are just excited by the UV LEDs; different dyes give different colors, like dayglo colors in sunlight. Ultimate would be Qdots which are excited at 405nm and never bleach with HUGE quantum yields!
@mike6789k Can you make a video of your other project? I'm about to build a so called sun jar but I'm unsure whether to go for the usual frosted glass or clear glass with tons of tiny glass shards.
If anybody wants to do this without building a semi-complex circuit, just use a power resistor, full-wave bridge rectifier, and high-power LED to replace a speaker. Computer speakers and car amplifiers already have active frequency filtering built in. Start with a high resistance first and increase volume to max, then decrease resistance until LED achieves normal brightness. Diffuse the light to avoid eye damage. Heatsink high-power LED's.
@glasscube the filters arenistortion caused b't quite what i'm worried about... it's more the distortion caused by the leds being inline to speakers.....
Question about your schematic, I noticed you connected your negative supply of your op amps directly to ground. Don't you lose signal that way? Since you can't have any negative output out of the amplifier?
I study Renewable Energy Engineering and I am having the analogue electronics class and this seems like a cool stuff to do in class. How can I make the circuit? Can I know? :)
could I do this with passive electronic realization (low cut/high cut filters, excluding op amps) or do I have to do it actively and use op amps to find the voltage gains??? I am also curious how you set up the left and right channels. Did both the left and right channels get combined into one input as a summing op amp? Thanks for any responses!
I know you say not to message you about "where is the schematic?", "what parts do I need?", "what are the resistor values" but it might be helpful to everyone if you even just took a good picture of the board and posted a link to it. I am trying to create this on a larger scale and I am having trouble with the schematic.
Arduino is the way to go..., I'm already gathering components around to make a 6 band spectrum analyzer, first with 3w white led (2 per band) and later 3w UV (too expensive for first prototype, so I'll be adding those later)
@nathantinnion Sure! I will be away on business for the week but I will attempt to post when I get back. The link you posted was the ticket. However, I have to agree with Mike. The various filters are really dependent on the music and how you have them set. Techno music works great because they hit every frequency under the sun.
oie una pregunta veo que en la parte de atras ocupas un protabot o algo asi me podrias pasar como lo hidsiste supongo que es para aumentar la energia o algo asi plis grax
Mike, I am trying to make the circuit, i am having a hard time, mostly with capacitors and resistors values. I bought a breadboard already, the 741 amp,the transistors and a bunch of r's and c's but cant get it to work. I dont have much experience in electronic circuits. If you could help me i would really apreciate it.
The schematic is here: uploderx DOT net/dphrag/SCHEMATIC1___PAGE1444.jpg It is entirely analog, as you would know if you read the description, so no arduino. Also, He has said repeatedly that he would not be make a guide.
I have never seen music sync leds work so well with the actual syncing part. really cool stuff
that is probablly the coolest thing ive seen in a long time.
Gorgeous lights. Dig the color selection, well done.
very cool, the camera quality also gives it the pulsing glow effect +++
its pretty simple, you run speaker wire to the LEDs through a mixer to make certain lights light up for certain frequencies to simulate the different instruments. the current from the speaker wire will make the lights pule to the different sound.
Hey man how about a tutorial on how this was done, i'm amazed....BEAUTIFUL
Wow, great job. That is very impressive. Neat song.
Song : Les Petit Pilous - Wake Up
Thumbs up :)
@nathantinnion

This is so awesome! I'm just learning, but hope to be able to make like this soon! (and thanks for the schematic)

Hey, could you put some links to the circuits into your description?
Excellent choice of track to demo it :)
@Trace314 sweet. i have done a very basic circuit and it works but cant seem to get low pass filters etc to work with it. blown alot of leds but good fun so far.
this is one of the better ones i think.
now play it in a Ruben's tube XD, and wonderful work on the music sync led's!!! :D

Schematics please, love this project
Excellent work!! It1s like so pretty! *--* what are the resistor values??
Any chance I could see a schematic? From what I could see at the end the circuit looks simpler than what I could come up with, and I like simple. Awesome with the highlighter liquid, looks cool.
hey mike nice circuit
noticed that you have used an adder circuit...
but i jus wanted to know what value of Vdd for the op amp that u have given pls reply
thanks great stuff ...
@Seok J. Min you need a individual op amp for each led with some x-over points on each led
@warlock0110 It's Snapple bottles. You can see the "S" on the green bottle.
Thanks for sharing these schematics!
this is the best demonstration I've seen please tell us how!
mike6789k Hello! I know this video is very old, but I'm also doing a similar project. What are the cutoff frequencies you used for the bass and treble?

The jars thing is a pretty cool idea itself.
Best vid on youtube for leds to music! great job! Can you please post a schematic for this? or a link for hack a day project?? THanks!
wow, I love what my bass does *.* nice music ^^
@mike6789k that you include the formulas for calculating the R/C values based on the frequencies, because they aren't that easy to find (took me several hours of searching, and reading a electronics textbook to find them.)

why pink water have diferent texture than the others?

oh my goat!!!!!!! this is super cool !!!! teach us come oh man!! yahoooo
nice work.. keeps me inspired for my avr fft moodlight ;)

@Trace314 im glad someone did, u able to post how u got ures working?
this is really cool thanks for the video!
cool!....nice effect u got there. can u show me how u did that?
this looks freakin sick!!!

good work!! you used active filters for frequency separation??
Nice work ! :)
YOU DESERVE A SUBWOOFER SIR
Very cool maaan! But I have a question.. Can you tell me the value of the resistors and capacitors?
Thank you very much!
This was originally poster a long time ago and the links no.longer work. Nice project can't find online
Oh okay. Yeah I've been looking up alot about filters and discovered RC filters is what i need to be looking into. Now did you build those into that circuit you have there???

i dont know how to build it...but im here for the good music :D
@mike6789k Can you make a video of your other project? I'm about to build a so called sun jar but I'm unsure whether to go for the usual frosted glass or clear glass with tons of tiny glass shards.
so you just have a 3 way converger or splitter or whatever its called with 9 volt leds? cool ill have to try this one.
If anybody wants to do this without building a semi-complex circuit, just use a power resistor, full-wave bridge rectifier, and high-power LED to replace a speaker. Computer speakers and car amplifiers already have active frequency filtering built in. Start with a high resistance first and increase volume to max, then decrease resistance until LED achieves normal brightness. Diffuse the light to avoid eye damage. Heatsink high-power LED's.
Perfect song to show it off! Looks really cool, got any code you feel like sharing? ;)
that was AWESOME....
PLEASE! GIVE US SCHEMATICS or a photo of the circuit!!! we're waiting since 2009 for you to make a tutorial!
this is perfect bro you are the one
@glasscube the filters arenistortion caused b't quite what i'm worried about... it's more the distortion caused by the leds being inline to speakers.....
Did you design/figure this all yourself or did you use a premade design?
Question about your schematic, I noticed you connected your negative supply of your op amps directly to ground. Don't you lose signal that way? Since you can't have any negative output out of the amplifier?
Dude dude dude dude, please please a how to video, that would be the coolest home project!
thanks and one more thing..
whats the volage gain aprroxx at the end of each op amp..
are the resistor and capacitor values in each adder the same
that is so cool how much to build one ?and post to the uk?i want one
THIS IS AWESOME!! may i ask what song this is?
wow , i love this one
how much you sell this for ?
if not so expensive , i love to have one
Great idea simple :] too
Plus it only requires a few of the fitlers and some opamp, mosfet, and low pass xD
this is a esetian in de electronic study's , conect 1 led in the terminals for de speaker, and the lamp is a combination for H2O + Cl caseiro :)
I bet this guy throws a boss party
Badass how did you make it?
I'd love a schematic if you have one, I'm currently doing something similar with a micro and I'd be great to cut costs and do something purely analog.
hi very good your video
I loved the music which is me Desis
I study Renewable Energy Engineering and I am having the analogue electronics class and this seems like a cool stuff to do in class.
How can I make the circuit?
Can I know? :)
@Living4DaMusic according to the description he uses ultra violet LEDs and UV reactive water.
I like..... any chance you could assist me with setting up something like this in a PC case... using LED lighting. Just red lighting????
This is soooo cool I want to make something similar! :DD
Woow i love it!!
Dude itz so awesome....can u make video on how to make it? please
could I do this with passive electronic realization (low cut/high cut filters, excluding op amps) or do I have to do it actively and use op amps to find the voltage gains???

this is so cool. Grat for my biz! how do i do this?
by the looks he used 3 low pass filters (maby low pass with high pass) and that chip is used to amplify signal.
I would like so much you show me how did you make them? a tutorial? please. I love it.
I want to know how that was done, would be a great pc case mod/party item
Hey, can u teach us how to do this?
It's Awesome! :D
for the UV-effect you can change the original led's with uv-led's
you just have to hook the leds up to the subwoofer/ speaker. that's how the skytec 10" blue LED PA speaker works
@nathantinnion

Is each each light programmed to be tripped by a certain voltage or beat or is it computer programmed?
