LM386 amp buzz? Answered

Should be an easy question :-) I built my first 386 based amp, and it works great, except for input volume control. Almost every schematic has 10K pot at input (connected to pin 3 on 386). Problem is when I turn pot all the way down I hear buzzing noise, especially if source is off. Also it doesn't cut source volume noticeably so I tried using 10M Pot, and it works except buzz is now super loud. So how would I control volume?

Laptop Fan Buzzing? Answered

Hello Everyone, Need some advice here. I have noticed a slight buzzing sound in my fancy gaming laptop's fan recently. Its only audible when the fan is on its highest speed and then you wouldn't notice it if your volume is up. I'm fairly certain the problem is that the fan is slightly off balance. Here's why: 1). I completely dismantled the laptop and cleaned it of all dust and particles, so its not clogged or impeded in any way. 2). The sound stops if you tilt the laptop approx 30 degrees in any direction. (The sound actually gets louder until the 30 degrees is reached, then it completely stops). My question is: What should I do about it? Is it really much of a problem? Do I need to replace it? If I do, my warranty literally expired 1 week 1/2 ago, is there anything I can do about that? I feel cheated by the timing personally.

Guitar Amp Static

Following up on my other thread with soldering, I managed to get my circuit for a distortion pedal all wired up.  I've got the clean end working, and nothing at all on the distorted end, but I'm not concerned about that just yet.  On the clean end, I get a really annoying buzzing sound, like when you turn the amp on with a cable plugged in with no guitar on the other end.  What would be cause of this?  Possibly outside interference since I haven't actually put this into an enclosure yet?  This is the schematic I followed.. https://www.instructables.com/id/Simple-overdrive-effect-pedal/step2/The-schematic/ and the sound from my amp is similar to this.. http://www.youtube.com/watch?v=ZUeRLC4z8f4 No, it's not the amp that's the problem because it works fine without the circuit.

LED Lamp Buzzing (not a bulb)

About a year ago, I came across this LED lamp that was on sale at my local Target store. It caught my eye because it had a little tray at the base of the lamp along with a USB port for charging my devices. Since the first time I plugged it in and turned it on, it makes a buzzing noise. At first it didn't bother me, but now that I am spending more time at my workbench it has become annoying. I understand it is kind of common for LED bulbs to do this because of the dimmer switch being outdated, however this lamp is not dimmable nor is it a "bulb" so to say. It's about 7-9 SMD LEDs on a circuit with a rocker switch. If it makes a difference, I do have my lamp plugged into a surge protector and don't have anything plugged into the USB port located at the base of the lamp. What can be done (other than throwing it away, of course) to stop the buzzing noise coming from the lamp? Thanks in advance!

Advice for a buzzer element

Hello I am developing a small device which requires  a sound alarming. The idea of the device is to be attached to your phone for example and if you wonder where your phone is, the device will turn on the sound alarming in order to give you information for its location. So, I am searching for a buzzer element which: - consumes up to 3.6 V; - is small (diameter up to 20 - 25 mm) and thin of course; I decided to use a buzzer element similar to this one http://www.digikey.co.uk/product-detail/en/CEB-20D64/102-1126-ND/412385 but I am not sure if it will do the job. I am concerned about something else, I have a buzzer at home which produces sound of high frequency and when you close your eyes it is absolutely impossible to find out where the sound comes from. Can somebody help me, please? Thanks a lot!!!

electromagnet gauge makes buzzing noises?

Hi, i've been working on a project that involves reusing the electromagnetic needles commonly used in 90's era ford gauges. i can get it to work fine, but it seems to cause a buzzing noise as it is doing the work. there are three pins, ground, power, and signal. right now i just have it working off of 5v. when i have it going, and you hold the needle with your finger, you can feel it vibrating. i'm using an arduino nano, a npn transistor, and the gauge with a PWM output. do i just need to put a capacitor in? or how do i keep it from buzzing like it does? its not a loud buzz, but you'd notice it if you were in a quiet room.

Display buzzer

I am not good at designing electronics. Could someone point me in the direction of a suitable circuit to do this... I have a device with a backlight on an led display, the backlight is normally on but can be switched off sometimes the backlight flashes to alert the user. on for 1 sec, off for 1 sec approx. I want to add a circuit to it without changing the existing circuitry when the backlight comes on I want a buzzer to sound for 1/2 sec if the backlight is on then nothing happens, nor should it buzz when the light goes off. So: 1. switch on device, backlight comes on, Buzz 2. backlight is on for length of time but no buzzing 3. backlight starts flashing 4. goes off, No buzz 5. goes on, Buzz 6. repeat from 4 until the backlight stays on this circuit and buzzer is going to have to be very compact to fit in the device. I might substitute a phone vibrate for the buzzer. Any suggestions ?

Need a schematic design for a simple circuit.

I was wondering if anyone here could help me design a particular circuit. The "device" would need a single button. When said button is pressed a buzzing sound would occur ( kinda like in game shows, you know that wrong answer sound?) then wait for five minutes and automatically buzz again by its self. Press once (BUZZ) wait 5 minutes buzzes again without the need to press again. I am perfectly capable of reading schematics and building prototype circuits. I just have no "nack" for design as of yet. Any help on this issue would be greatly appreciated. Thank you for reading my post. PS: I am a little rusty on some of the symbols, therefore a legend would be great.

My NST is buzzing- how do I stop it?!?!?

Hello, I am in the final steps of perfecting a Tesla Coil that I started a few months back. I only got the spark gap to fire in one test run. Every other time, the circuit does nothing, and my new 10 kv neon sign transformer buzzes loudly and ominously. I'm really worried that I'll burn it out. Why is it malfunctioning? How can I fix the problem?Update: After a little experimenting, and checking all connections, I've found that the one time that the spark gap fired happened because of a wiring error (i connected the gap in series to the transformer instead of parallel); this resulted in a spark across the gap, but no oscillation. I'm starting to think that the capacitor's are the problem. I originally believed that the required capacitance was .003 uf, but I recalculated that and found that it was actually .0079 uf. This could explain why a spark couldn't jump. I'll order some more, and see how that goes. Thank you all.

Need help with guitar ground wiring! Answered

 Earlier this year I bought a super cheap Squier Affinity Telecaster. A couple weeks ago I opened it up to change a tone cap. Every thing seemed fine, all the pickups worked the tone control worked the switch worked and the volume control worked but I noticed that there was quite a bit more buzz and it would stop whenever I touched anything metal on the guitar. Ground problem right? Anyway, I thought I had accidentally snapped the bridge ground wire or the main ground wire (the only ground wires that weren't 7 strand). So I ordered some 7 strand luxe cloth wire and replaced both of the ground wires. I tried the guitar again, the buzz was quieter but was still there and it reacted the same way as it had before when I touched it. The buzz stops when I touch the bridge, anything in contact with the bridge (i.e. strings), and the control plate. The buzz is very faint and the reaction to me touching the guitar is even more faint.   My soldering skills are pretty poor. I think it's likely that my solder joints are the problem but I would also like to know if there are any other possible causes because since the first time I have redone the solder joints a number of times.  If my soldering is the problem what is the best solution to the problem other than connecting myself to the guitar via wire every time I play? And what is the best way to improve my soldering skills for future projects or even this project? Thanks, Adam

very strange speaker amp problem?

I have two 5v speaker amps. One i made myself and another I got from my cousins junk box. Anyways, when I connect the speaker it has a very very loud buzzing. The strange part is when I touch almost any terminal in the circuit with my finger the buzzing stops and it plays normally with very little buzzing. The amp I made I have followed the circuit schematic exactly and triple checked everything. I have tried grounding the parts too but that didnt work so I know its not a grounding issue. Another thing, while I was making the amp I tested it and it did the same thing but it started working when a 10k resistor popped out of its place and was sticking straight up in the air, it was originally connected to ground. please help.

Loss of temperature sensation in fingers? Answered

I've never had this problem until now...here's the story. Well, I was outside the other day, and it was freaking cold out. Probably about 9 degree's F. I was wringing cold water out of a towel (long story) and the cold really hurt my fingers. First my fingers felt cold, then nothing...just this buzzing sensation. Realizing that wringing water out of a towel with bare hands at 9F is probably a stupid idea, I rushed indoors and defrosted my hands with warm water. But all I felt was buzzing, not warm water. Hmm. So today I was melting wax in a soup can in boiling water, and I touched the tin to see how hot it was. It didn't feel hot, so I just grabbed the boiling hot tin of wax and poured it into my mold. The wax dribbled onto my fingers. I didn't even notice it! Later that day it occurred to me that maybe i was having trouble feeling how hot things are, so I experimented. I ran hot water over my fingers, but it didn't feel hot at all. It just feels like my fingers are buzzing or something.  Stranger still, if I IMAGINED that the hot water is cold, it suddenly feels cold! If I imagine it's hot, I get that buzzing sensation. It's probably just a temporary condition, so I was wondering if it's ever happened to any of you folks?

Servo Help!

First of all, I'm not the best with Technology projects, just putting it out there in case its an obvious answer. Anyway, I have an arduino project that im working on. All it is is a servo that spins after 24 hours, I thought it would be a simple project (I've worked with arduino a little bit) and I wired it up correctly, I'm sure of that, but after I coded the program, the servo wouldn't spin! It just made a dull buzzing sound. At first  I thought it was my program, so i tried just about every basic "sweep" program i could find online about servos. Every program had the same result, a faint buzzing sound and no spinning. Next i thought, maybe the 5v wasn't enough to power the microservo, so i used a external 9v and ended with the same result, buzzing, no movement. Can Anyone Help me?! Please! Is it just a simple solution? Or is my arduino micro controller not working! Please help me because i would like to enter the project in a contest that ends soon! Thank You!

Fastest you have ever been.

I have a car, but no permit or license. One day, my brother told me to bring him something while he was at work. I was driving down the street going the speed limit or a little over and under. I turned onto the main road Speed limit, 50mph, and just went 50 or so the whole way. and when i got back onto the highway, this guy is following me to my bumper basically, so in the non passing zone just getting on i am going about 25mph, as you are getting on it is 35mph limit, as soon as it reaches 50mph, i jam the gas, it goes into passing gear and in no time i am doing 80mph. and on an S-curve still doing 80. On the stretch i am doing about 60mph, and decided i should just stick to the speed limit. Got a story? A Nice Morning Drive It was a fine morning in March 1982. The warm weather and clear sky gave promise of an early spring. Buzz had arisen early that morning, impatiently eaten breakfast and gone to the garage. Opening the door, he saw the sunshine bounce off the gleaming hood of his 15-year-old MGB roadster. After carefully checking the fluid levels, tire pressures and ignition wires, Buzz slid behind the wheel and cranked the engine, which immediately fired to life. He thought happily of the next few hours he would spend with the car, but his happiness was clouded - it was not as easy as it used to be. A dozen years ago things had begun changing. First there were a few modest safety and emission improvements required on new cars; gradually these became more comprehensive. The governmental requirements reached an adequate level, but they didn't stop; they continued and became more and more stringent. Now there were very few of the older models left, through natural deterioration and . . . other reasons. The MG was warmed up now and Buzz left the garage, hoping that this early in the morning there would be no trouble. He kept an eye on the instruments as he made his way down into the valley. The valley roads were no longer used very much: the small farms were all owned by doctors and the roads were somewhat narrow for the MSVs (Modern Safety Vehicles). The safety crusade had been well done at first. The few harebrained schemes were quickly ruled out and a sense of rationality developed. But in the late Seventies, with no major wars, cancer cured and social welfare straightened out, the politicians needed a new cause and once again they turned toward the automobile. The regulations concerning safety became tougher. Cars became larger, heavier, less efficient. They consumed gasoline so voraciously that the United States had had to become a major ally with the Arabian countries. The new cars were hard to stop or maneuver quickly, but they would save your life (usually) in a 50-mph crash. With 200 million cars on the road, however, few people ever drove that fast anymore. Buzz zipped quickly to the valley floor, dodging the frequent potholes which had developed from neglect of the seldom-used roads. The engine sounded spot-on and the entire car had a tight, good feeling about it. He negotiated several quick S-curves and reached 6000 in third gear before backing off for the next turn. He didn't worry about the police down here. No, not the cops . . . Despite the extent of the safety program, it was essentially a good idea. But unforeseen complications had arisen. People became accustomed to cars which went undamaged in 10-mph collisions. They gave even less thought than before to the possibility of being injured in a crash. As a result, they tended to worry less about clearances and rights-of-way, so that the accident rate went up a steady six percent every year. But the damages and injuries actually decreased, so the government was happy, the insurance industry was happy and most of the car owners were happy. Most of the car owners - the owners of the non-MSV cars - were kept busy dodging the less careful MSV drivers, and the result of this mismatch left very few of the older cars in existence. If they weren't crushed between two 6000-pound sleds on the highway they were quietly priced into the junkyard by the insurance peddlers. And worst of all, they became targets . . . Buzz was well into his act now, speeding through the twisting valley roads with all the skill he could muster, to the extent that he had forgotten his earlier worries. Where the road was unbroken he would power around the turns in well controlled oversteer, and where the sections were potholed he saw them as devious chicanes to be mastered. He left the ground briefly going over one of the old wooden bridges and later ascertained that the MG would still hit 110 on the long stretch between the old Hanlin and Grove farms. He was just beginning to wind down when he saw it, there in his mirror, a late-model MSV with hand-painted designs covering most of its body (one of the few modifications allowed on post-1980 cars). Buzz hoped it was a tourist or a wayward driver who got lost looking for a gas station. But now the MSV driver had spotted the MG, and with a whoosh of a well muffled, well cleansed exhaust he started the chase . . . It hadn't taken long for the less responsible element among drivers to discover that their new MSVs could inflict great damage on an older car and go unscathed themselves. As a result some drivers would go looking for the older cars in secluded areas, bounce them off the road or into a bridge abutment, and then speed off undamaged, relieved of whatever frustrations cause this kind of behavior. Police seldom patrolled these out-of-the-way places, their attentions being required more urgently elsewhere, and so it became a great sport for some drivers. Buzz wasn't too worried yet. This had happened a few times before, and unless the MSV driver was an exceptionally good one, the MG could be called upon to elude the other driver without too much difficulty. Yet something bothered him about this gaudy MSV in his mirror, but what was it? Planning carefully, Buzz let the other driver catch up to within a dozen yards or so, and then suddenly shot off down a road to the right. The MSV driver stood on his brakes, skidding 400 feet down the road, made a lumbering U-turn and set off once again after the roadster. The MG had gained a quarter mile in this manner and Buzz was thankful for the radial tires and front and rear anti-roll bars he had put on the car a few years back. He was flying along the twisting road, downshifting, cornering, accelerating and all the while planning his route ahead. He was confident that if he couldn't outrun the MSV then he could at least hold it off for another hour or more, at which time the MSV would be quite low on gas. But what was it that kept bothering him about the other car? They reached a straight section of the road and Buzz opened it up all the way and held it. The MSV was quite a way back but not so far that Buzz couldn't distinguish the tall antenna standing up from the back bumper. Antenna! Not police, but perhaps a Citizen's Band radio in the MSV? He quaked slightly and hoped it was not. The straight stretch was coming to an end now and Buzz put off braking to the last fraction of a second and then sped through a 75-mph right-hander, gaining ten more yards on the MSV. But less than a quarter mile ahead another huge MSV was slowly pulling across the road and to a stop. It was a CB set. The other driver had a cohort in the chase. Now Buzz was in trouble. He stayed on the gas until within a few hundred feet when he banked hard and feinted passing to the left. The MSV crawled in that direction and Buzz slipped by on the right, bouncing heavily over a stone on the shoulder. The two MSVs set off in hot pursuit, almost colliding in the process. Buzz turned right at the first crossroad and then made a quick left, hoping to be out of sight of his pursuers, and in fact he traveled several minutes before spotting one of them on the main road parallel to his lane. At the same time the other appeared in the mirror from around the last comer. By now they were beginning to climb the hills on the far side of the valley and Buzz pressed on for all he was worth, praying that the straining engine would stand up. He lost track of one MSV when the main road turned away, but could see the other one behind him on occasion. Climbing the old Monument Road, Buzz hoped to have time to get over the top and down the old dirt road to the right, which would be too narrow for his pursuers. Climbing, straining, the water temperature rising, using the entire road, flailing the shift lever back and forth from 3rd to 4th, not touching the brakes but scrubbing off the necessary speed in the corners, reaching the peak of the mountain where the lane to the old fire tower went off to the left . . . but coming up the other side of the hill was the second MSV he had lost track of! No time to get to his dirt road. He made a panicked turn left onto the fire tower road but spun on some loose gravel and struck a tree a glancing blow with his right fender. He came to a stop on the opposite side of the road. the engine stalled. Hurriedly he pushed the starter while the overheated engine slowly came back into life. He engaged 1st gear and sped off up the road, just as the first MSV turned the corner. Dazed though he was, Buzz had the advantage of a very narrow road lined on both sides with trees, and he made the most of it. The road twisted constantly and he stayed in 2nd with the engine between 5000 and 5500. The crash hadn't seemed to hurt anything and he was pulling away from the MSV. But to where? It hit him suddenly that the road dead-ended at the fire tower, no place to go but back . . . Still he pushed on and at the top of the hill drove quickly to the far end of the clearing, turned the MG around and waited. The first MSV came flying into the clearing and aimed itself at the sitting MG. Buzz grabbed reverse gear, backed up slightly to feint, stopped, and then backed up at full speed. The MSV, expecting the MG to change direction, veered the wrong way and slid to a stop up against a tree. Buzz was off again, down the fire tower road, and the undamaged MSV set off in pursuit. Buzz's predicament was unenviable. He was going full tilt down the twisting blacktop with a solid MSV coming up at him. and an equally solid MSV coming down after him. On he went, however, braking hard before each turn and then accelerating back up to 45 in between. Coming down to a particularly tight turn, he saw the MSV coming around it from the other direction and stood on the brakes. The sudden extreme pressure in the brake lines was too much for the rear brake line which had been twisted somewhat in his spin, and it broke, robbing Buzz of his brakes. In sheer desperation he pulled the handbrake as tightly as it would go and rammed the gear lever into 1st, popping the clutch as he did so. The back end locked solid and broke away, spinning him off the side of the road and miraculously into some bushes, which brought the car to a halt. As he was collecting his senses, Buzz saw the two MSVs, unable to stop in time, ram each other head on at over 40 mph. It was a long time before Buzz had the MG rebuilt to its original pristine condition of before the chase. It was an even longer time before he went back into the valley for a drive. Now it was only in the very early hours of the day when most people were still sleeping off the effects of the good life. And when he saw in the papers that the government would soon be requiring cars to be capable of withstanding 75-mph headon collisions, he stopped driving the MG altogether.

Fly Powered Planes

Flies generally buzz about and don't do much besides feed the local spiders, but here's a a couple ways to put them to work by powering tiny airplanes. Check out the models below from the 70s or the video for something more recent to show you that, yes, this crazy idea actually works. Insect Power via Neatorama

How can I build a giant ball like a big hamster ball?

I am looking into creating a virtual reality experience controlled by something like the VirtuSphere (www.virtusphere.com).  I know there are giant hamster balls out there, but they are inflatable so I don't think they would be strong enough for what I want to create.  Also, solid balls would be waaay too expensive (like the BuzzBall or a Zorb).  Ideas?

Want to make a Light-up Timer, Looking for help/information?

I work with students that are disabled. Several are deaf. I would like to make a small timer that lights up or blinks instead of buzzes. The timer would need to be small like hand held size. If there is anyone that could point me in a direction... OK, the right direction. Thanks
