Nicely done. I build one also for my final college project back in the 90s. It was only a 3 channel for use in a car application. It was powered by 12VDC and drove 3 different 12VDC color neon tubes. I had to use a condenser mic for input and not a line in level. My project seems small by comparison. Great job and thanks for sharing.

How absolutely fantastic. Thanks for being awesome!!

Are you interested in a much more elaborate analog color organ? My brother & I spend many years building a pair for a disco setup. There are 3 distinctions from yours. First, we did not mix the stereo channels. Each side has separate processing. Secondly, for each audio filter output, there are 2 light channels, one getting brighter with the level, & a second getting dimmer. This gives almost the same light level at all times, but from different lights. Third, there is a problem with audio having more dynamic range than lights. During quiet or loud passages, the lights "freeze up". We solve this with automatic gain control that continuously adjusts the gain to give "active" lighting. For 2 stereo channels, 3 filter bands, & the normal & inverted lighting, we get 12 light channels. Rather than mount the lighting in a central display (as you have done & was done in the '70's), we put spot wash fixtures throughout the room, driven by SCR's. Later these were replaced by single-color LED lamps. In addition, we modulate colored fluorescent tubes (using magnetic amplifiers constructed from old burned-out Variacs), also distributed throughout the room. If you are interested, I have circuit schematics & some videos of setups I have done.

Woah! That's cool. I'd definitely be interested (especially in how you solved the automatic gain control). My email is mark@markv.me.

This is simply fabulous. A real 3d sound and light experience, not on a screen. Could you share it's influence on you in the past year. Perfecto!

Excellent. Crazy PWM control and the use of Sawtooth signals is Outstanding. Perhaps a Video on your power supply build, I'll download the sch. Cool

Nice. One of the best I have seen. Could you post a video on how to build it or a link to a DIY build?

very cool, more people should see this and learn electronics

WOW, this is awesome :D

very nicely done

Sweet project Coaster. Could you please do a video of your shop and the equipment you have on your shelves? Thank you.

Could this be modified to drive the colors of a computer monitor playing a movie/video?

Hello, nice project, what program did you use to make the PCB? Thank you.

@COASTER1921

Altium Circuitmaker. Totally free and no limit on number of projects if you're willing to make them open source. Further, the program it's based on is the most popular in industry so if you're going to work as an EE for a company it's a great skill to have.

thanks, I will use it.

that nice can that be used on a car sound system

Being a 77 year old retired person with lost of in-house time on my hands I would like the info to create this magnificent color organ from the past, I also would like the files necessary to get the pc board and parts list. cheers and thanks for the great reflection to my past years.

I've uploaded the gerber files to my website markv.me if you wish to make your own. I couldn't find my old schematic files but can get the resistor and capacitor values from my current board. You will need to use a service like smartprototyping, pcbway, OSHpark, or jlcpcb to get the PCB manufactured. I didn't make any assembly files so all components will need to be soldered by hand.

Would you be willing to give me all the information i need to recreate this project with my sis. It looks like i would be a lot of fun to do.

Hey! This is a awsome project and I was wondering if I could ask you some questions about your project.

@@fartlord111 I used Altium Circuitmaker. It's pretty good and the professional version widely used throughout industry. That being said, recently, I've been recommending kicad over it as the learning curve is slightly lower and the compatibility is nearly as good. Further, Kicad is open source and free with no limits. As well as just being overall faster. The BOM materials aren't as good, but as a hobbyist that doesn't matter at all.

Nice Job, I have an analog color organ I designed on KZread as well.

Nice. Would you be willing to sell the main board?
