This was my first ever electronics circuit 9 years ago... And now I'm doing my electronics engineering final year dissertation

"Let's plug it in"... Famous last words... I try to make my perf-board projects as pleasing to the eyes like yours but I feel like I will never achieve such greatness...

Yeah, i haven't seen such a perfect circuit in my life.

I bet the music on all of collins lab videos is made by himself on his synthesisers!

Collin man... Your videos are AWESOME. I can't say really why. Most of the time I am memorized till the very end of it, keep up the good work. Cheers!

your videos are the only reason I'm subscribed to this channel...

I really love Collin's videos. Keep on good work Collin!

I love this! thanks for showing us how to make a disco organ.

Grate as usual. The Music the timing to the music The explanations, the “dry” humor its al here and I love it =) Never stop making these please

Hi, please update the link the video description , the current one shows the topic is removed from make website

Thank you again Collin, for another wonderful project. Now to plan for a few more things, order up some parts, and fire up the Metcal...

This dude was ahead of his time

Thats pretty cool... First time in a long time makemagazine makes something cool

your video style is absolutely outstandind!!!!!!

you certainly do create a neat and organized layout ... excellent !!!

I love it when pieces fit in so uniformly, like at 4:53 :)

Love the "to the beat" component placement.

This guy is the reason I subscribed!!!!

You, sir or madame, have deserved a damn badge.

I just made this! It works great! Dimsanda, pin 3 is not technically a power input. It's "virtually grounded". The 12 volts should be the only supply voltage.

Liked your style. And you had good soundtracks too!

Another really awesome project. Thanks Collin! :-)

Hey Great Video!.. Actually i was making one but having a problem deciding the amplification factor!..i mean the Vmax varies with the whole song! So how do i decide the exact voltage amplification??!

Wow this is awesome! Ive got visions of modifying this to include relays or something and then getting it to switch higher power mains circuits. Made a disco light box a while ago that had 3 mains LED circuits in it powered by an old Christmas light sequencer and some bridge rectifiers. If I could get this to switch some relays or something then I could use it to make it light controlled. Also you could wire a mic into it as well and have it so that when 3.5mm jack is plugged in mic disconnects.

wow, i was literally talking to my friend about how he can do this instead of buying speakers with it and now i have something to show him! :)

I have no idea what hes talking about but i like watching his videos!

just got all the parts cant wait to put it together:)

I LOVE THIS, I'M COMPLETELY SOLD, NOW I WANT TO BUILD THIS!

Collin is the new KipKay. These vids are awesome.

simply awesome. great video!

Cool episode, I did enjoy it, but didnt really learn much, I wanna learn how to do this. It seems like the ideas are endless with the lights and all. Thanks!

this is actually a pretty cool project i might attempt this one of these days XD

hey, loved your video. can you please provide the parts list for this project and if possible, a print of the schematic. thanks alot.

@NikySportsPromotion it's a voltage divider with Vout=Vin/2 and a a voltage follower circuit (acts as a buffer), so you draw no current from the divider, which would make it have a different Vout depending on the current you draw.

What if you want a strip of led's?

like the video, but adore the music underscoring the building! What's it called?

Got some good tips out of this, thx. Also, those pcb masks on the wall are pretty cool :)

What I might do is etch a huge circuit board to hold a bigger LED display, and use a lot more LEDs. Cool video!

this is awesome .. i love it so much !!!

where can i get ready made circuit like this i have plenty of LED strips

In sure you could find one on eBay, or radio shack sells a pre made circuit board with components and a much simpler layout

' wow that cooool with LED lights with sound pulse... can come with a control dimmer / speeding / volume or not

Hi. Can I use TL084 and C2383 instead MC33204 and 2N3904? I can't find MC33204 anywhere. I finished this Circuit with TL084 and C2383 but it not work,my LED isn't lighting. I can't find TS921 too,so I don't have virtual ground circuit but I used one 680uF capacitor to make same virtual ground. Some body help me :(

You basically performed a "Deal with it" the geek way when you said "Safety first"! :D Awesome project!

@JohnMPed with the op=amp that there you may be able to use a dynamic mic, but you probably will need another stage of amplification or more gain on the pre-amp section

@JohnMPed ya, you would probably need an amplifier, but you can find simple ones to build out of just 3904 or 3906 transistors. if you want to go all fancy you can use an op amp

That is one awesome project.

Hello Colin, thanks for the video, can you tell me if this configuration will power more than the sets of 4 LEDs (I'd like to put 15 or so LEDs in 3 pots and use them to light a stage)

Hey collin (or anyone), would this work if in place of the audio jack I attached a piezo disk which was in turn mounted onto an amplifier or speaker. Basically my sound set-up has only so many outputs, none of which are available for this to plug in, but if I used the piezo just sitting on one of the speakers would it pick up the sound vibrations and transfer them into the circuit just the same as if the audio source was wired straight in?

nice project...nice camera work !

@qstendious You can put an electret microphone at the signal input pins or you can add a preamp w/ a microphone, if you want a wireless color organ

finishing one of these projects makes you feel so goo about yourself (i'd imagine cause ive never manag to finish one yet)

@Catology there's a place out in orange county that sells the old school color bars. they're made by bowman if I recall correctly. google truck and car shop orange county and you should be able to find it in their online catalog

The IC label sticker is a brilliant idea.

Can I solder on some type of mini microphone and then if I did would it flash the light by the ambient sound in the room and by "speaking" to it? Thanks.

yes you could, I'd use a piëzo and use this as the incoming signal maybe the value for the first opamp should be changed so it boosts the signal a bit more but i think it'll be allright

Cool video. I made one of these with light bulbs over 20 years ago, back when the Commodore 64 with tape drive was high-tech. A color organ was the only way to get lights to flash back then. /John

Great project! I like the music too!

How did u generate the computer visuals

Wow! that was awesome!

Collin, you sir, are awesome. That is all.

This guy should have his own channel.

It's a half way point between V+ and Ground for the op-amps to use as a reference.

I've had my laptop apart before, I'm sure I could make a condensed version of this with SMT parts and put the LEDs in the frame of the LCD screen

im looking to do this but with a much larger scale, say 50 led lights for each section (mid/high/low) and also i want to know how i could seperate them so the mids could be on one wall of my room and the highs on another etc. please help

can it generate visuals from speech? Are there programs like that?

this is soooo freakin' nerdy.. I LOVE IT!!

please tell me what song is at the end when you use it i really want it

Might have to make one of those.

@masterelyt do you know any of the spec changes i would need? (like resistors and all that jazz?)

A quick question, how well would something like this work with a high output source, like say a car stereo?

@supafly377 It just provides 2,5v... the 2 100k resistors function as a voltage divider. the Op amp functions as a voltage follower. Audio signals are alternative, so in reference to 2.5V you get +2.5v and -2.5v. The 2.5v "virtual ground" goes to the "-" of the 3 Op Amps. To get a more LED's you need more OpAmp based filters.

can i ask if this comes with everything, the power supply, the audio jacks etc

Could you replace the led's and the transistor's with vu meters and have a 3-channel audio spectrum analyzer?

Great Project !! What is the voltage of the power supply?

would you be able to implement this for live situations?

what kind of graph is that? like the circuts.

Hey guys, just to clear something up...The schematic is not my design. I don't quite know where it came from, but it was modified by me and a few other users of my website over the years. Originally it may have been based on a old and now defunct kit but I don't quite remember as it is 15+ years ago. Either way, I'm glad you found the info useful and glad you enjoyed the project!

how many holes were in the perfboard you soldered your components to? and does the kit come with the board already?

Its connected to the 12V supply V+ corresponds to the pin of the MC332 (the IC that contains 4 OP's that he used)

Would you be able to put in a dynamic microphone instead of the line in or would it not have enough signal strength to read?

I ordered the color organ kit just to save some time but plan to combine the color organ with the Atari Punk console as the input. Eventually, use as a toy for my 3-year-old grandson.

Hello, I would like to ask if the LED into 5050 article lamp can continue to operate?thank u :)

The treble LEDs flash most. Could you wire it to suppress the treble when the bass is flashing? I think this would give better seperation of the colours.

can this be built using just tl072 opamps?

when he types,does the space bar turn the lights on and off?

What soldering iron do you use?

nice :). how would i make a bigger scale version?

I would love to try this, but with more LEDs for each color... any tips? (im not much of an electrical whiz, so keep it simple please!)

Does anyone know if this 'kit' could be re-purposed to power "el wire" instead of leds?

you mentioned using header pins to use a separate off-board display, if you do, would you make a video about that also? 'cause that would be pretty awesome.

very nice video Collin. I´ve ben looking for something like this to decorate my son room. My question is: Can i put maybe 15 leds for each color ? i know that vcc from transistor don´t support that. but how can i adapt the circuit for that ? Thanx in advance. Keep working !!!

Bre Pettis was always my favorite person from Make.

@GeirMovies Do you hear the leds screaming

nicely done

@23skidoonk THANK YOU! That's just what I wanted but couldn't think of the name. I'm going o do a little dance now.

This guy is the best guy that ever guyed.

Does V+ on the virtual ground mean the 12V supply or the input signal?

Hi, How do we connect the input of the circuit to the speaker actually? the wire from the input needs to be connected to which part of the speaker?

Oh man.. I wanna do this. Does the kit come with instructions for newbies?

@MultiJohn12321 no that's to change the volume right? i mean like it can let you see how loud it is, like an equalizer =D

Can we make the same using LED strips instead of small LEDs... how the circuit will differ. Thanx in advance

@vandorb12

Totally! Just be careful about voltages and power consumption of the LED strips. The only difference would be the LED strips replacing the LEDs, and depending on how bright the LED strips are, maybe a few resistors.

@seandonelan5834

For a longer strip of LEDs, you might want to add a few N-Channel MOSFETs to the LED output of the organ.

Great music. Is any of it available anywere?
