Musical Lights

Hey, I recently saw; and i want to make that. I read the schematic at (that link doesn't work, use this one:  for it, but, I'm still quite confused. The parts that are the most problematic to me are the high, low, and mid pass filters. i  don't understand what they are, and how there made. If anyone could help me, thank you.

led to music? Answered

Ok... i have been looking into this for the past month tried to use a TIP31 transistor to make my led light strips flash to music in my car by using my sub amplifier as an audio out source...... and it would not work so i was wondering if you someone could help me out to make a box that would allow for audio in from my amplifier that would have a circuit that would perform the task of making my led light strips flash to my music. thanks.

Noise or Music?

The "Bose" sound system is based on chamber resonance like that of musical instruments. This is the difference between a whistle and a flute. The mouth piece of a trumpet is raw without its additional plumbing. The noise of a piezo-electric sounder is raw, but chambered to resonate...better. A trumpet is basically an acoustical waveguide device. Consider this and lets see if you can "WOW!" the crowds with your sounds. The trumpet mellows the sound of the mouth piece by reflecting the sound repetitively off the inside walls of the horn. The angle is low so the acoustic wave reflects many times along the length. What works for you?

Music Transfer box????????

At school they showed us a video of a device that supposedly you could place on a cardboard box and music would play through the box. How can I make this? I was thinking on using a piezo element. Any ideas????P.S. you would plug it in to a headphone jack.

Lights Responding to Music

Hey Guys, I know there are a couple hacks that show how you can make a single LED or even a couple react to music (the bass makes them bright...) but I cannot find a way to make a string of lights react to music.  I want a longer string of lights to be able to do this so I can put them around a table, does anyone have a solution? Thanks

Arduino Music Lock

Had this idea for some time and ill possibly do it when i learn more electronics stuff. But for now, i'll share the idea! So imagine you have a secure locked door. Theres no keypad or keyhole anywhere on or near the door, but there is a microphone setup on it. The only way to open the door would be to play whatever song or series of notes that are programmed into the "lock" with a musical instrument. Since there are several lock-based instructables here that use arduino boards, would it be possible to use one with whatever required components to make a lock that opens with music as a key?

So as you can see in the video at the end of both songs I am having a issue with it cutting/shorting out. All i can think of is the tip31 transistors im using are overheating maybe? but what is really wierd is it shorts back to the speakers?? I have one transistor driving the blue leds and one driving the red leds. the red leds are being powered by a 9v supply and the blue is 15v( dont remember the MA but they both provide plenty. They are wall warts. When i  plug in the 9v power supply it makes a high pitch buzzing noise.... If anyone has any pinters i would appreciate it. Thinking of adding more transistors.... I cant figure out how to link it so just copy paste the link below into your browser...; and i'm following this diagram cause it does not have a switch like the others.

Music Making Software? Answered

Hey everybody. Just a few questions about music making softwares. First off, if you make a song from (the software's) loops and pre-determined notes, can you still copyright that song? Or do u owe the company money, or can u not copyright it at all? Also does anyone know a really good software I can buy thats relatively cheap? I don't want to spend $400, but I'm willing to go up to $100 or a bit more. Lastly, does anyone have any good guides for getting into this type of music making?

Music Video Help?

Me and my friends are making a music video for a class we chose the song "A Dirge For The Underground" by Attica! Attica! We have most of it  done, but we are having problems with the last shot, we are doing of an explosion (not with actual bombs, just implying there are bombs). We don't mean like Die Hard, Action Movie, Jump to the Ground at the last second explosion, but the explosions you traditionally see when a building explodes, lot of smoke and debris as opposed to fire and a slightly sooty hero/heroine. It's just going to be blowing a lot of immediate debris and smoke blowing outward and then smoke drifting up. Best idea we've had so far is rent a big ass fan and set up a temporary business of cleaning out fires lol. We unfortunately do not have access to the media lab so digital effects are unfortunately not an option. Any better ideas (that don't damage the location, the owner would be pisssssssssssssed)?

LED Lights and Music

To get a general idea of what's going on, I'm a CAD student and we are studying Electricity -- I was looking at a recent instructables guide that showed how to make a box that lights up to music. Well I was planning on doing something similar with a few twists. 1) Dependant on the frequency, there are certain LEDs that will light up 2) The ability to plug in a MP3 Player (Zune is my test subject) 3) The addition of two (2) small speakers around the size of maybe 2 inches My questions pertain to what exactly will I need to do here and where I can find information on the parts required for this project. By all means please try and refrain from giving me specific parts (If it requires a Transistor with some requirements [If a transistors do have any differences] please just say Transistor with x requirements). I don't mean to sound rude but I really want to try and figure things out on my own, but I'm not sure where to really look. I would grab bits and pieces off of these Instructables (Which are all very nice) but I want to actually know why to use a Transistor by reading up on it. If anyone can also mention to me a good place for speakers of smaller size I would appreciate that as well. Assuming I'll have problems with connecting certain things like a plug for a Zune -- if you are willing to lend your help please just mention it as a response. Thank you all a head of time!

simple electronic music keyboard

To all: I teach music in Elementary school. In my classes we play the recorder. In some of my classes I have some very special needs students. So they have been pushing on paper buttons that represent the recorder. They do a grate job. I would like to try and make something that can play the same pitch as our recorders and not have to change their set up very much if at all. Now they have a large black paper with circles of colored paper with note names on them. The push down on the note names as we (the rest of the class) plays the song. They are not able to play (hold the recorder) well enough to join in due to their special needs. They do seem to be getting it though. They can push the buttons at the right time. I thought if I could hook up something underneath their buttons with a small speaker etc........ What can I do that won't cost very much??? Thanks. Carmine

FM Transmitted Music: iPod --> Receiver

How best to move a servo to music?

Hi All! I have a quick question, I want to move a servo in time with music and was wondering how best to do that with an arduino. I found someone on Instructables who made a talking skeleton open its mouth when the volume of the music rose above a certain point but just remapping the analog in signal from my wave shield is not moving the servo as smoothly as I would like, it just sort of jitters around. I guess this makes sense as the voltage changes quite a bit to create an audio wave form. I have a wire from R7 on my wave shield plugged into an analog port. Would the MSGEQ7 chip be the best way to accomplish my goal or is there another way? If anyone is curious I am attempting to move the arms of a portal turret in time to the turret opera.

How to make an alternating music box?

So I want to make a music box that has several phrases that belong to the same song and have it alternate between them (verse/chorus/verse/etc..). In order to do this I will build a few separate movements but it's the stopping of one and triggering of the other that I need help with. I'm new to electronics and have been learning as I go with this project but I am unsure how to make something that can do this. My idea is that one movement will repeat probably 4 times then stop when another starts and so on. The movements are simple: a power supply (two AAA batteries), a potentiometer, and a motor that turns the "roller" which plucks metal tines. There is another question I have about this project: The tines and the "picks" on the rollers are connect to LED lights so each time one is plucked, the LED light turns on. This is simple enough to create ( but I want the lights to each stay on for a little bit longer than this contact lasts..maybe just a second. I am not sure how to accomplish this. If anybody can help me with either of these two question, that would be greatly appreciated. I plan to publish the entire process on here with credit given to those who help me so don't be shy! Even if you aren't sure your idea is correct, all thoughts are welcome. Thanks!
