Thread: LED Equalizer

I had an idea as a little project to learn how to solder and stuff like that to create an LED strip that mounts to the top of my box above the subs and either creates flashing patters that go to the beat or that flash up like an equalizer (If you have ever ran a band PA with a feedback detection system like the Berry equalizers, you know what i mean) to certain frequencies. Dunno how hard or long it would take or be, but just as a fun project idea. Anyone care to insight me on where to start?

I run live sound systems and i think that the feedback detection lights are bs. Imo i think the DBX driverack does a great job for feedback detection and elimination.. But i think it would be cool to have an eq like that

Yeah you're right, the Berry ones NEVER picked up the frequency before I heard feedback, or even during. But i meant something like that, a volume detector essentially. FB detection lights are basically volume analyzers I think...but something like that would look cool going to the music, at least I would think...lol

Any idea where a diagram would be or how I would go about making one that would run symmetrical across the top of a 36" box? Lol.

I have been meaning to pick up a cheap microphone and hook it up to a circuit to see what kind of voltage or resistance changes it has when I let it listen to my subs. I am a noob at circuit design, but I have worked with resistors and thermisters and have a lot of books about circuits so I might be able to figure it out. My goal was to make a very inexpensive, customizeable circuit with readily available parts. Most of the kits that you buy come with a pre-programmed chips, or blank ones that you need to program, so they are essentially digitally controlled. I would like to create an analog one if possible. If anyone here has any experience in circuit design, chime in and we can make this happen!

I'd say something with a sound input, then branch it off to sets of VU meters at different frequencies? I was thinking about something like that...

Now I just need to learn how to create a crossover circuit for those...
