Color Organ Triple Deluxe II – Kit and PCB
Color Organ Triple Deluxe II is the return of the classic color organ of the 70′s using LEDs. Color Organ divides sound wave into three bands; low, mid, & high, and lights different color LEDs based on the volume.
Color Organ Triple Deluxe II uses all discrete transistor circuit for authentic “sound to light” function – no ICs, no microcontrollers. Assembly is also very straightforward and beginner friendly.

Notes:
Kit assembly requires basic soldering skills.
You need a 12V DC power supply (AC adapter) (300mA or higher current capacity – such as this one) to operate Color Organ Triple Deluxe II. Use of regulated power supply is recommended, since non-regulated AC adaptors typically produce output voltage much higher than they are rated. (Typical “12V” non-regulated AC adaptors can output about 18V.) If you want to use one of those, make sure to masure the actual output voltage, and only use it if the voltage is lower than 15V. (Try 9V rated ones.)

Hi!
I’m trying to understand your circuit but I’ve some difficulties with the pre-amp part, can you explain how it work please?
Thank you !

Hi! This looks like a really cool project. I had just a quick question:
Would it be possible to use an LED light strip (similar to http://www.superbrightleds.com/moreinfo/top-emitting/nfls-x-series-high-power-led-flexible-light-strip/1464/ ) for each of the high – mid – and low LEDs?
If I understand correctly these LED strips have the resistors already incorporated so I would exclude the resistors directly infront of the LEDs in your design. Do I have this correct? Would there be any other modifications I would have to make?
Thanks!

Yes, if you keep the strips short enough – maybe up to 6 sections (18 LEDs). And remove the current limiting resistors like you mentioned.
To connect longer strips requires some (or quite of) design change.

Thanks! I really appreciate the quick response!

Have build it with the 2n4401 works fine,i wonder if i can remplace q4-6-8 for another transistor like tip31 which support up 3A so i can use lots of leds

I think larger transistor need more base current to work, but it might work if the LED current is about 1A or so.
It’s hard to scale up beyond that, without using more sophisticated technique.

Looking at the schematic, is the polarity of C2 correct? I’m more used to thinking that the positive side should be toward the input signal.
There’s a guy on the instructables site that is having problems; he’s showing the polarity of C2 the other way…

The polarity of C2 is correct. Electrolytic capacitors need to be biased (voltage applied) to work well. While input voltage is AC so it averages to 0 V over time. Voltage at the base of the transistor is positive, so you see why the positive end of the cap goes there.

When you say super bright LEDs do you mean something like a 1W high power LED?

If i wanted to make this circuit control 120vac lights, would i just have to connect a d2w203f or similar relay to the led voltage?

I’m guessing but that should work.

Is there a way to use 2 color organ triple deluxe II’s and change a few components on the second one and have a 6 channel.

You can change the filter frequencies, but since low and high channes are not bandpass filters, they won’t really work as 6 band. What you need are 4 bandpass filters, and a high-pass, and a low-pass filters.
Also, you will need much narrower band band-pass filters for more than 3 band. Which means using OP-amp based bandpass filters will be needed.

Looks like a fun kit. The effects are quite nice, especially with the black PCB as the background.

I think the Kit Contents BOM should actually read 18 LED’s and not 9 as currently listed, given that both the assembled demo and bare PCB have 18 through-hole LED locations.
Cool kit!

Thanks for pointing that out. Thanks!
