Need a custom sound or vibration device which reminds me every few minutes

I do some concentration / relaxation exercises at times to keep myself fresh and efficient. When I'm at the computer, I have set a small program to sound a sweet chime every 15 minutes. And I can do a short, few seconds to a minute exercise and go on with my work. But, when not at the computer, I can't remember always to do this. When I remember, it's already a few hours or so and the link breaks and it takes more time. Can someone offer to help with a simple (electronic or whatever kind) idea of making a cheap sound or vibration device that can remind me at least once in 15 minutes? I know I can use my mobile, but I have a cheap Samsung mobile that only has 10 alarms, out of which 2 - 4 I already use as other reminders. Thanks for the help. Regards, RS

Guitar Hero 3 For Wii Disk Audio Flaw

I was meaning to post this sooner but completely forgot. Anyway, If you don't already know, Guitar Hero 3 Legends of Rock for the Wii has a disk flaw. The flaw makes the sound in mono instead of the Dobly Digital Surround Sound that is advertised on the box. Activision will replace it for free though. The way you can tell if you have a flawed version of the disk is if you look right above the Activision logo and if theres a little white star there or not. If there is one you have the new version and don't need a replacement. If not you can go here, fill out the form and then they will send you an envelope for you to put your old one in and send back and then finally you get sent a new version. I just thought I'd let you know. Good Luck!--Note-- If you send them a disk thats anything other than the old version of the Wii GH3 game they won't send anything back.

Looking for ideas for a synesthetic exploration project!

I have a project I'm working on, the purpose of which is to create a kind of synthetic synesthesia by taking the information about different people normally interpreted by one sensory system, and transform the way in which the information is presented, such that it is being interpreted through a different sensory system. The most important thing to me is that there is some kind of legitimate scientific basis for the way in which the information is gathered and then reinterpreted. So, for instance, one iteration of this project that I've done was, using litmus papers, I determined the pH of various people's saliva. I then took photos of each individual and also scanned each strip of litmus paper; I then color tinted each photo with the color from their litmus strip, and thus, one could "see" what that person tasted like. What I'm looking for are ideas for sensory data collection. Or, really, even just data collection in general. I'm an artist by trade, and an amateur scientist by interest and inclination, so figuring out ways in which to reinterpret the data isn't something that I need as much help with. Particularly, I'm really stumped when it comes to measuring anything having to do with smell, and in specific, how to measure a given person's ability to detect smells (for instance, quantifying the extent of someone's hyperosmia). I know olfactometers and electronic noses exist, but have no idea as to how they work or how to get my hands on one w/ an art student budget. ;P I got the idea to ask around here for suggestions after stumbling across this instructable for measuring muscle sounds. Thanks for any help or advice you might be able to provide, and I hope you have a very lovely day! =D

Has anyone done this?!?

If you don't have it set up like this already, then try it. If you have a smallish room, try putting your subwoofer in the corner. In my room the bass lights up like the 4th of july compared to when the box is sitting in the middle of my room. I'm listening to it right now and it just sounds wicked. You the bass more than you hear the subwoofer itself moving and groaning at the low notes.

Problems when recording a bass guitar

 Hi, I have experienced some difficulties trying to record my bass with my computer. I get a okay result at first, but when after a while the sound gets more and more weak. It gets weaker, but still gives some peaks where the sound is stronger. Happens with every mic I've tried, even with straight input. Could it be the soundcard? Trying to upload a soundsample.

Tweakin the stereo

How would I go about moving my speakers around to get that much better sound out of it. I drew a little crapjob diagram of where I have all the speakers now. It sounds pretty good, but I know the sub could probably find a better spot than in the floor infront of my tower speaker (although the blending of the bass is rather superb). What if I put it under my desk in the middle?

Strange Planet Part Two

Following along in the last post about the wild world of water, let's see what other natural oddities our Earth has for us. There's a strange sound coming from the ocean, they're calling it a "Bloop." The earth is known for whistling caves, and plopping mud puddles, thunder and earth quakes, so we know the earth is one vocal creature. But the bloop is new, and as of yet unknown. This is what we know: "Although the sound matches the profile of a living animal, it is much louder than any known creature can produce. Any creature that could produce such a sound would have to be many times larger than the largest whale."The story is here.What do you think it is?_BG\\via neatorama\\

Noise cat scarer device with with motion detection

I need a cat/pet scarer device.  Main problem: Indoor housecats scratch bedroom doors during the night.  Observations: I''ve had partial success with a comercial product called "Ssscat Cat Spray Control System". It uses motion detection and a bottle of compressed air, shooting a burst of air on detection. The concept is good, but it's not easily available anymore and was a bit expensive. It seems that cats are more scared of the sound it makes than the burst of air.  Ideas: I was hoping to use a "Pyroelectric Infrared IR Motion Sensor Detector Module" and a small audio speaker to make a static sound (white noise) to accomplish a goal similar to commercial solution. A sound loudness slightly above normal talking sound would be enough.  The sound legth should be about one second. Maybe two LEDs lighting at the same time would also help. I would need about 2-5 such devices. They would have to be battery operated with an on/off switch.  Could such devices be easily built from components? If so, I would need on finding the right components and instruction on building the device. I have only basic skills like soldering and tinkering, but I don't know how to design electronic devices more complicated than simple LED projects.

Weird and wacky electric sounds (theremin, vocoder etc.)

Anyone know of any really cool sounds you can make with electronics?I'm thinking of making both a Theremin ( and a Vocoder (, the first of which seems like a relatively simple circuit, the second seems much harder.there are a few wiring diagrams on the 'net for a theremin, there's links on the wikipedia page (check and you can also buy kits at some electronics shops.vocoder seems like it must be a load harder, and I haven't been able to find any wiring diagrams, and as far as I know, there aren't any kits available. there's a demo of what it does at wondering if anyone has experience with either of these weird and wonderful devices, either using them or making them, or if anyone has any other strange sound makers that should be brought to public attention?hrrmm... wonder how hard it would be to turn that old evolution MK-149 into one of these ?

WTV020M01 sound module need help

Hi I recently bought a cheap WTV020M01 (WTV020SD) sound module from china. i know you get what you pay for but i cant really afford to spend big on that kind of electronics or else i would have. Any ways my problems is i have wired up the component as instructed, loaded up the audio files as per instruction on the micro SD card and connected it to power and hit the play pin. And NOTHING happened. i then tested to see if it was getting power and yes the power was fine. After being frustrated i tried moving around the power connector and discovered that if i placed the power in the reset pin the module lit up as if it was working and all the buttons worked but still no sound. i am not sure that as its a cheap component its a dud or have i just wired it up up wrong, or an i missing something like an amp. any help would be good thanks. here is some links to the component specs;=ETC⟨=en

Guitar Wah Wah Pedal Help!

My VOX Wah Wah pedal (V847) is not working. The bypass is working. However, when I turn ON the wah-wah effect - there is only a clean sound of the guitar and a very THIN sound of the wah-wah, it sounds more like a VOLUME pedal than it does a wah-wah pedal. I believe this is the schematic: From what i've gathered, the problem lies in the capacitors (because apparently capacitors are what create the wah wah? i'm not entirely sure myself) I've replaced the C2 (4.7MF) and C3 (.22MF) What could be the problem? Please help! P.S. are MF, mF, and uF all the same? Thanks.

My Amps! My Amps! *Screams an old crazy man in the deli section*

Yes yes, shhh I want to ask a serious question today. I traded one of my kenwood amps for my parents as their sony surround unit is really shitting out and the sound sounds terrible and the entire control panel on the front is messed up. I just want to know a couple things about the sony to see if I can fix something. The panel, well that's quite interesting to explain and if I posted a video of it you guys would probably think I edited it or something. So imagine this, the bass + and - buttons are beside the treble + and -, two sets of buttons. If you push one of the bass adjustment buttons, it glitches and turns the treble for example, up or down randomly and doesn't do what I wanted it to do. It's like this with all of the buttons and seemed to have happened after we moved here. And I know it didn't get banged around because it was transported in the back seat of a car on blankets to the new house and carefully carried in by me. If I say try to use one of the surround sound adjustment buttons it glitches out and acts like I hit another one that's beside it in any direction. Hard to explain but I'm just damn confused as to why it suddenly happend (dry solder connections?). Damn this post is long and it's only half Bad sound, I will not tolerate it under my household, but on the other hand it was a $400 unit back 5 or so years ago and I KNOW it used to sound good, with a such a profound richness of bass that just punched right through you. Now it sounds like shit, the sound is garbled, distorted when turned up, it's not really noticeable until you turn it up fairly loud. I have/had my technics tower speakers hooked up to it and they sounded like shit when I turned them up, yet on my kenwood they sing like the wedding singer days. Any ideas nachomoma? I'll add another note that for most of it's life it's been hooked up to a pair of 250 watt (peak) optimus floor speakers and whenever we played it, it got HORRIBLY hot and warped the top a bit when it was on, enough to push it in and make it spring back up again with quite a force. I liked this receiver a lot and would like to use it again, but I don't know where all these "degradations" came from and despite my useless amount of amp questions/bickering's about I would really appreciate any ideas from you guys. Thanks.. -Punk

Customized Alarm Clock

What I want to do is this, -get rid of my alarms stupid sounds -insert a custom sound -do it cheap -and make it small enough I can still put it in a custom casing (the casing is the easy part, I'll have no issue making that.) I have looked around and have seen several ways to hack alarm clocks but I can't see how any of them would help me out with this particular problem. The way I see it I will probably need to rewire the clock so that it sends power to an external device when the speakers are supposed to go off. The only other way I can think of is having a small computer with one of those pre-programmed clocks but that would be more expensive than buying the sound recording clocks and a bigger pain to fit into the casing. I also think I heard someone talk about making homemade circuits, I don't know if that would work at all but it's worth mentioning. I would like to be able to find easy to follow instructions that are CLEAR and not super complicated. Any help would be appreciated! BTW, yes, I have looked at the sound recording clocks online and they all look like crap or are way to expensive to bother with.

architecture for grade 4-6, need lighting ideas

I volunteer on Saturdays in Watts/LA for a program with kids from grades 4-6. The program involves 6-8 week "classes" taught by volunteers, and I'm an assistant for a new class on architecture. We're building a structure, and I want to include both lighting and sound. For lighting, I sincerely apologize, I have no experience and not much time, can someone recommend a simple way to let the kids build some different LED effects, ideally AC powered, that they could incorporate into the scaffolding we built last week in first class (the structure will be about 6x6feet.) The second question, I think sound is essential to architecture, I happen to have some sanyo MP3 players, I was thinking of buying small MP3 speakers for each, and then letting kids experiment with what a wash of different sounds and music would sound like within the structure.Amazon MP3 speakers start at 20$. Any other options? I think it would be great to have strpped down speakers so that kids can build the speaker housing to incorporate into the architecture.  I can find + and - on a battery. Thats about the level of my competence.

GE Microwave Makes Humming Sound with Smell

My GE microwave (JE1860SB 002) made a cracking sound and stopped working. After some research, I removed the cover and checked the fuse and it was good. I then checked the thermal flame/sensor and discovered it was burned out. I replaced the thermal flame/sensor and now the unit comes on but makes a loud humming sound and has a burnt smell. The next step (according to my research) is checking the diode (cable) which is attached to the capacitor. It appears I need to discharge the capacitor before proceeding? --- BEFORE replacing the sensor, the unit had been unplugged for over one week….AFTER replacing the sensor, the unit was plugged in for about 5 minutes on Jan 25, 2018.- What is the best/safest way to discharge the capacitor? Is an insulated screw driver or pliers needed or will a rubber handle tool work considering the time it has been unplugged? (Capacitor pictured below) - Should I remove the two connecting wires and diode before attempting to discharge the capacitor? - If the diode is bad should I still check the Magnetron? - If the diode is good, what is the next item to check/test?

Noise cancelling megaphone

Hello all:) I was wondering if I could get some help and advice about a project I've had in mind for a while. The idea is to use a modified electronic megaphone to produce sound that's antiphasic of the microphone input. I want to keep the execution as simple as possible to retain signal quality and keep it something I might be able to do myself with a little studying up. I got the idea when I noticed if you incorrectly wire a couple speakers one can produce output that's 180 degrees out of phase, cancelling most of the sound emitted. Ultimately I'd like to use the device to help quiet the sounds of the power tools I use as a favor to my neighbors and to save my hearing a bit:) This should be doable since I could keep the megaphone near the source. Thanks a bunch for any help, Pete

Velleman sound-to-light kit

A Velleman sound-to-light kit (Radio Shack MK103) is a small circuit board powered by a 9v battery which lights LED bulbs when an audio signal is received by the microphone. I would like to connect this board directly to the headphone (output) jack of my audio device (metal detector), thereby bypassing the microphone input. This would allow visual operation of the detector without the use of headphones. When an object is detected it would illuminate an LED as opposed to sending an audio signal. Is it possible to de-solder the microphone on the circuit board and solder in a 3.5mm male connector which would plug directly into the audio output device? I have never worked on a circuit board before and I have ZERO knowledge of electronics, but the kit is only $8 - so I think it's worth a try - if the electronic wizardry is correct, that is. Thanks in advance for any help! -Bruce

Headphone showdown

I'm currently in a dilemma over the next pair of headphones I'm buying. Does anyone have anything bad to say about certain ones? (Or better yet good things). The three I've narrowed down to are: - Solo HD's  from beats     - These are a tad more expensive, but I personally like them and have heard great things.     - Detachable cord     - Great sound     - Most expensive (119USD) - Skullcandy Lowriders    - I've gotten mixed reviews here, some say that they are crap yet I personally know someone who had a pair of these for 3 years and they were still in one piece.   - A little uncomfortable, but durable.   - Decent sound   - Also the cheapest (40USD) - Ifrogz Vertex    - I have a pair of these which are broken, the cord is a tad cheap but the quality is fairly good otherwise.    - Decent sound    - Mid priced (50USD) Thank You - Nerdman

sound-sensitive LED lights that respond to music, sewn into clothing

Hi there.   I'm new to the boards and off to the big festival in the desert next week.  Every year I make some kind of a flashing suit-- usually they are EL Wire -- which is kind of cool to dance in.  I recently took an Arduino course and I thought it would be great to make a jacket that reacted to sound.   Ideal:  Had a pot to deal with volume (of club music vs. speaking) and was able to power a row of LED's down each arm and possibly down the side of the torso. I have a board- I don't have time to program it- I'm wondering if anyone can help? I'm happy to sew it and all that stuff.  Yes, time is tight , but it doesn't have to be perfect! Let me know. There is some budget- not much but some.

Electric didgeridoo

Bored with traditional digeridoos, Kyle Evans made this electronically modified, Bluetooth PVC didgeridoo. The Bluetooth allows him to not be tethered to a computer and the controls on the sides allow him to modify the sounds in the middle of a performance. It takes a lot of breath to power the 4.5 foot didgeridoo, but with a feedback feature he can keep the sound going and catch a breath, which is a little easier than the typical circular breathing. This took 3 months for him to build at a cost of $300. You can hear a sample of it in action here. You Built What?! The Electronic Didgeridoo

Sound location & motion tracking robot head

Hi guys I hope this is ok to ask about as I have followed Instructables for ages but not used the forum part before. I have a bit of experience of arduino projects and doing basic sketches for them but nothing as ambitious as this so am seeking a bit of advice if possible. I'd like to be able to have a droid/robot's head that can rotate to focus on the direction of a sound, then if it sees a person once looking in the direction it heard the sound, to then roughly track them (move its head) with a camera. I'm fine with motorisation and that side of things, but I'm not sure if this sort of fairly elaborate setup would be possible with an arduino or would need something more powerful like a rasp pi? I'd imagine that I would need an array of several mics as inputs around the bot in a 'circle', and code that can estimate the direction by means of the signal strength from the mics when it hears a noise.  I think this might be something I can manage to do, but then it'd need a suitable camera and a means of tracking and I've no idea how the tracking side of things would work with that. I'd be grateful for any pointers to get me going thanks.  It's not something I could do without help but hopefully doing it bit by bit and with some advice I'd be able to do this, as I would really love to make it work! Many thanks! Jim
