I want to make a simple sound board.

I already found a instructable that plays a portal song using an avr: https://www.instructables.com/id/Portal-Still-Alive-on-AVR-microcontrollers/ I wanna make something just like that, small, minimal, but i want to know how to do it propoerly, can someone point me the way? I wanted to do simples short sound samples, with a button, that's fairly simple, but i'm not familiar with the audio part. I know i have to convert wave sound samples to hex, but the whole process i still don't know right. I am familiar with eletronics and arduino, but this project has limited space. I can use pic's, perhaps AVR, but i got limited time, as this will be a gift. We gona do a potato Glados, with a real potato with copper and zync nails, using a booster/thiefbug as a potato only manage to give 1.2V . Theres is a similar produt on ThinkGeek, we could just buy it, but doing it is way more symbolic. Considering that we live in Brazil, the simples way possible is always prefered, importing stuff takes precious time. I'll probably stick with that avr and modify the code, but any help would be awesome.

Modded Fart Machine, plays the 14-20 kilohertz sound

Ok, because I am not so tech savy in circuitry, I am willing to give my first daughter's virginity and an Island in Dubai to the person that can show me how to build this: Ok, the idea is a Modded fart machine that plays that intensely annoying high pitched sound that only young people can hear, between 14 and 20 kilohertz...hopefully somebody will know how to switch the programmed chips and utilize the fart machine's speaker and remote control system. It would also be quite helpful if you could add a 9-volt battery with a resistor for long life, and possibly put in a more powerful speaker for maximum annoyance.

need some help with my project (boombox)

Hello guys so i have been working on this project for some time (i know its not complicated) and i need some help with it. So i bought this old-school suitcase it was mainly made out of plastic so i glued some plywood  on the inside of the suitcase, ive cut  some holes for the speakers and vuala its semi-completed. So im using 4 mid-range speakers and 1 low-range speakers, so i yesterday i made the first sound test and to say the least the sound quality was terrible (i know it wont be a high quality sound boombox but i have made one some time ago). So my question / request would be if you guys have any suggestions maybe you know some cheap but decent quality amp or know anything about building speakers or stuff like that ( because i have pretty close to none experience in building them) BTW im using lepai lp 838 I would really appreciate any advices or suggestions. THANK YOU! ohh and sorry if this thread is missplaced or if my english is horrible.

How would I build a two way proximity detector with changing frequency based on location to its pair?

 I am looking for a quick instructable that will make two devices that change pitch based on proximity to its pair. It doesn't seem like it would be that hard, but I am not good with stuff like this (with soldering on boards and even knowing what all those things do) but I know enough to know that thats what its going to take. Thanks for your help.  [edit: not really an edit, but more of an after thought, a post script if you will -- Think Geek makes a shirt like this but it uses lights as it gets closer... I want to use sound and frequency)

Where can I salvage a small amplifier circuit to power the skateboard boombox I built? (Yes, you read that right)

There's a slot in between the speakers to mount a tiny MP3 player. When you take it outside, the speakers are very low, and I'm assuming it's because there's no amp. I need something small and easy to hack, because I'm terrible at building my own circuits. And also a decent way to power it. Any ideas, friends?

Free Earphone Buds

Every lose ear buds (the soft part on them), everyone has now you can get free ones from Acoustic Forge http://acousticforge.com/, you just pay S/H and you get free earbuds, if you want to support the Acoustic Forge product : IronBuds, which are fully-hackable headphones you can make a pledge at kickstarter (link on webpage). For donating they will send you a pair (or more) of headphones and you will be supporting new, modular, headphones, each part of the headphones is separate, so you can customize the  bud, headphone, cables, and much more! If you lose or break a piece rather than buying an entire new set you just have to get a single part of the headphones!

My idea is to attach a contact microphone to the wrist to listen to finger-taps and determine which fingers produce the taps. Assumptions: - The tap sound propagates along the bones like in tubes,  - Each finger produces a characteristic sound signal. - Pattern recognition of sound signals identifies the sound and the finger that produces it. Any help? Thanks

Sounds with electronics

So here goes, I am trying to figure out how to make basic sound generating machines. Preferably generating a sound that can be modified with a potentiometer or something of the sort. The principle is simple, these will be for messing around, possibly, if the result is good, using in some random recordings of mine, so most of the machines will have a jack out plug. Anyhow I was wondering, what, in a circuit, actually makes sound, what is the base of all sound generating electronic devices (synth, analog stuff, beepers) what actually creates the wave, the current that is sent to the speakers? Have I just answered my own question by saying current? Is it just the electrical current, and putting random resistors, capacitators, potentiometers and stuff changes the sound that is generated? Any help is more than welcome! and if anything good comes of it, I'll post some sound clips!

Speed of sound question !!

My friend and I were debating : If somebody sitting in the back of a plane cockpit going faster than the speed of sound ( the whole plane that is, imagine it was the SR71 ) insults the pilot at the front will the pilot hear it and turn around to punch the guy sitting in the back? This one might be more understandable: Can someone sitting in the front of a super sonic plane hear the guy in the back, without the help of microphone and all that crap. My friend thinks it is impossible becose the plane is going faster than the speed of sound and the sound from the guy at the back will not go fast enough for it to catch up. I think that is total nonsense Anybody knows the answer ????

G.E. dielektrol capacitor making popping sounds internally Answered

I recently acquired a G.E. 40,000 volt capacitor and initially it was fine but it has started making loud popping sounds inside while charging and discharging. It sounds like there might be arcing inside but it still holds a charge just fine which is quite strange. The sound always comes from the same exact spot and the capacitance has decreased from 1.88 uf to 1.5 uf. I'm wondering if inside the cap there is several smaller ones and maybe a connection came loose during shipping but I really don't want to pull it apart because it's welded shut. Any advice on what I should do would be helpful :) Thank in advance!

I can make the headset, but I wanted to add something to it. I want to be able to put a small device that will play sounds (JARVIS quotes) when you push a button. What I'm envisioning is something like you see in some toys. It has multiple sounds, but one button. It plays through one sound effect when you push the button, the next one the next time you push it, and so on. I've seen ones that will do a sound for each button with multiple buttons, but that's not really what I want. One button, multiple sounds, and it cycles through them. Thanks.
