'i do not get any sound when i view the videos what am i doing wrong
Topic by deedee808
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!

i need to know how to make a circuit the will emit sound with levels as high pitched as a dog whistle i been looking around but i can't seem to find one which allows you to control the frequency along with the pitch and tone i'd appreciate any advice and or help on this along with any information leading to any good instructables on here that fit the discryption thank you to every who gives the feed

I was wondering if anyone had any simple sound circuts with variable pitch? It doesn't have to be very fancy just beeps and boops ( beeps and boops are preffered actually) Ii just need something that can create sounds with variable pitch and of any length

This is a rather interesting website... It converts the first 10,000 digits of pi into sounds.Here is the website!It will come up with some keys. You then select a note for 1's, then one for 2's, then one for 3's, and so forth. It's hard for me to explain, just give it a shot. There are instructions on the website.

I am making a robot, and want to make it say "mole-e." I want it to be a clear reference to "wall-e." There is a long story behind why I want "mole-e," so I won't go into that. I am planning on making a very simple mp3 player that is triggered by an Arduino. Basically, I know HOW to make the robot produce sounds, I just don't know how to make it say "mole-e." There are mp3s and oggs readily available of the "Wall-e" sound bite, but does anyone have a clue as to how I can sythesize it to say "mole-e?" Any software reccomendations or tricks? Can I record it and then edit it to sound like "wall-e?"

Hey homeboys and girls. This is Bilal checking in from Eric's dining room table. So it's true, I did have a bit of trouble with Airport Security. They made me miss my flight checking out all my crazy scary gadgets. It would be irritating but hey, I'm sure loads of people haven't seen a metronome before. Gasp! It ticks! Arriving in SF would have been quite unsatisfactory without a brief car chase so thankfully security obliged us with a short run with their tiny electric cars. Never fear, Eric, Christy and I made a swift getaway to the hills. Go Volvo go! -BG (thanks for breakfast Eric)

Hello, I recently purchased this item from ebay. It's a "30s Light Sensor Record Device Module Music Box Sound Chip For Greeting Card" It comes with a pre-recorded happy birthday song. Now I want to change that song and I am pretty sure it can be done somehow, because I can see some connections available, except I am not sure what they mean and how to use them. The seller responded that there is no documentation and if I want certain sounds I have to send them the files and they will record them for me before shipping... which is ridiculous... I want to be able to change the songs when I please. The connections marked on the board say: TG1 TG2 TG3 GND VDD PW1 and PW2 Any suggestion could help.

I bought a cheap answering machine, but it's too big for the container I want to put it in. What parts can I use from it? I just want it to record a sound and play it back when a button is pressed. Also, I salvaged a part from a touch lamp. How can I incorporate this for the power?

Could a certain sound frequency cancel out smell? as in the sound waves dissolve the smell molecule? i need to do a lot more research on this... but if it actually heads in the direction of a product where a non-hearable sound kills all the smells i copyright the idea as of now if you steal my idea and make money i will kidnap you and shred all the money you make until it is liquid and inject it into your bloodstream.

Good Afternoon everyone, A friend of mine asked me to help him build something and I sort of hit a snag in the process. I know how to make LED's flash to the beat of music but what he wants is so that way when there are sounds around him the LED lights flash with the sounds around him (Such as if he was at a party, the LED lights would flash with the beat of the music even though they weren't connected to it.) Is this possible and if so what would I need to build or get? Thank you! Sincerely, Khris

I looked up at bat detector, a device that converts ultrasonic signals into audible sounds. Most bats produce high frequency calls which are often higher than a human ear can pick up. A bat detector picks up the frequencies and then converts the sound into a lower, audible frequency. I was thinking if I could get a bat detector, I use it to capture the ultrasonic sounds.While bat detector could pick up these high frequencies, it would be interesting to see how it will pick up the faintly heard, to human ears - sounds of the industrialised areas/city or even at isolated/quiet areas. The bat detector I want to use is this - http://www.magenta2000.co.uk/acatalog/B ... _Bat4.html I'm thinking of hooking up the bat detector to a digital recorder and a binaural microphone and capture the sound through those equipments. I would greatly appreciate your suggestions/opinions on this matter.

Is there a machine or something you can make where you can plug in sound effects files and then as you push different buttons it will play the effects on cue? I have been searching and can't seem to find anything. Thanks for the help.

Hey there fellow modders/hackers/builders. I am in need of your help. First off, my keyboard is broken so I may miss some mistakes. Now to my problem, I have an idea for a project but have run into a problem... How do you add a single sound to a project? I just need one sound to play when a button is pushed. After some Google searching, I didnt find anything that could help me. So if any of you know of a way to fix my problem please please let me know. Thanks in advance!

Guys, does anybody know how to make an "Active Sound Generator"? It produces an amplified engine sound and the car sounds louder. In retail it costs about 2000€ that's why I would like to built my own Active Sound Generator. Any car fans who can help me out?

I need a simple cheap way to make a laser during sound fir a project. I don't want something complex like the stormtrooper blaster, but a simmilar sound would be neat. I can fit 3 9v batteries into the case. Also note I will be using a momentary switch to power LEDs fir a flash effect, and I don't want to gave to turn it down. Simple and small is what I need. Whatever works gets best answer and credit in my instructable.

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 ????

Hey all, Here's an idea maybe one of you solder-jockeys can help me out with: Ever have a sound that you'd like to find the source of, but your ears can't tell you where it's coming from? I'd like to build a circuit to do that. I was thinking of something like three electret microphones with op-amps between them in differential mode. That would give three signals that would be, presumably, the ratio of sound coming from each mic. (And, therefore, an indication of direction.) Of course, I'd also like to get an adjustable bandpass filter in there somewhere to isolate just the sound I'm looking for. That's the part that complicates all designs I've thought of. And then, if I could somehow figure out distance too, that would be the ULTIMATE! Here's one possible use case: A car makes a funny squeal noise a highway speeds. The mechanic takes out this device and magnets it inside the hood. He runs a control wire back to the cabin. Once the car is in motion and making the desire noise, he adjusts the BP filter using potentiometer(s) and a pair of headphones. The device tells him where (relative to itsself) the sound is coming from. Your bill is less because the problem was diagnosed quickly without a lot of guesswork. Thoughts?

Hey, my friend is a drummer and he's trying to install LEDs inside each one of his toms that would come on when he hits the tom. He doesn't know anything about electronics so he asked me and I don't know much either so I'm asking all you awesome people at Instructables. What I want is a simple sircuit that will not cost me above £5 that will allow me to do what I mentioned above. I have a soldering iron and can solder stuff easily so I just need the parts and (preferably a stripboard) layout. He will be using a max of 16 red 2v 20mA LEDs in each tom so the circuit will have to be able to supply either approx. 32v 20mA if in series, or 2v 320mA if in pararell. So, any recommendations?

I'd like some instructions on how to make a button that plays the same 2-3 second audio sound when it is pressed. It should be able to last for a pretty long while if you know how to do that. I want it to look like it's DIY and not from a factory but also good enough that someone would put it on their desk. I need the cheapest possible way to do this as well as instructions for a dummy who doesn't know much about technology. Thanks to anyone who can help!!

Hello!! I am planning several Halloween props that will benefit bigly from sound effects. For instance...I'm working on a mantel version of the demonic grandfather clock in Disney's Haunted Mansion. It would be awesome to have the sound of the ominous ticking, backed with a chime, that the "real" clock has. This could be an audio loop of just a few seconds. Some of the other parts of my scheme would be enhanced with short loops of sound effects or mood music...a minute or two at most. I don't have a background in electronics, but I can follow directions. Any advice on constructing a few, small sound effects modules? Thanks!!

I'm just curious about the people out there who are interested in ambient/experimental music and creating their own. What programs/microphones do you use? What things do you find yourself often recording? Do you manipulate the way your recordings sound to achieve a certain sound? I've just started recording with Bi-Naural Mics. When I want to do field recordings, I use I mini disc recorder. I offer all of my works free to listen to on Jamendo (maybe I should make an instructable on that site)!

At the current moment, I am in possession of a Casio Rapman (with VOICE EFFECTOR) that is in pristine condition. At the moment, my question is how would I go about changing the sounds of the different settings for the keyboard in order to make a 4-bit chiptune set instead of the early nineties vision of what things should sound like. Anyone know their stuff?

Whenever I play music out of my computer, a thing keeps popping up called Realtek HD Manager saying that I've plugged something into the microphone socket! I've checked both of them (Front and back) and nothing is in them! So I disabled by going: Start > Run > 'msconfing' > Startup, then disabling it. It told me to restart my computer for the changes to work, and when I booted it up again it had no sound, so I turned it back on and rebooted the computer and it still dosen't work! And yes, I have checked all the obvious things like if the sound's muted. Thansk, Flannel UK

Acoustic method could quickly catch counterfeit coins.You might assume that counterfeiters only bother with high-value bank notes, but there is a chance that some of the coins jangling around in your pocket right now are fake. If Mototsugu Suzuki gets his way, it may be that jangling that gives them away.Suzuki, a researcher at the Tokyo Metropolitan Police Department's Criminal Investigation Laboratory in Japan, has developed a way of examining coins based on the sound they make.In Suzuki's method, coins slide down a slope and then fall onto a brass block. The sound they make on impact is relayed via a microphone to a computer.Although the human ear cannot usually tell the difference between real and fake, a computer can. Genuine 500-yen coins showed four distinctive peaks of natural resonance frequencies in the 5-20 kilohertz range. This was not the case for fakes; some fakes produced only three peaks, while others showed four but at different frequencies to genuine coins.In addition to helping detect counterfeits, the sound data could be used to build up a database of fake coins, suggests Suzuki. This might help law enforcement officers to prove how many coins one counterfeit operation is responsible for. This would make for an awesome Instructable! Start with these two Instructables and get dropping pennies! https://www.instructables.com/id/Build-a-dsPIC-Oscilloscope-and-Spectrum-Analyzer-/https://www.instructables.com/id/Low-speed-AVR-oscilloscope/
