My surround sound system wont stay on. What's wrong with it? Answered

I have a Sharp sd-at1000 surround sound reciever, and while trying to hook up a speaker(front left if that matters) it sparked and turned off. Now when I turn it on it says "Hello" on the lcd and stays on for about 1 second before turning back off. From what I've found through research it seems to be a output transistor. Does this sound right? Looking at the circuit board I couldnt find anything that looked bad. Any ideas? Thanks in advance!

can you hack a toy to change it's sound & light funtions?

Is there a setup were you can hook up a toy to a computer & change the light & sound effects? I know the chip is small & covered over but a black epoxy, but is there a way  to get to it, touch an exposed wire running out of the chip to download new effect? Is there a substance to melt the curios black cover over the tinny chip?

Require assistance building a circuit with sound and lights for the Aperture Science Handheld Portal Device.

Last week, I constructed a prop ASHPD for my cosplay outfit for the Tokyo Game Show- being a generic male test subject. Considering the time crunch I had, I was not able to put as much detail into it as I would have liked. None the less, it came out pretty good. Now, I want to improve upon it. One of the upgrades I want to apply, I have no experience with. The layout of the circuit that I want is as follows: On/Off toggle switch. This is simply to preserve battery life. The device will also have 2 single press buttons, one for the blue portal, and the other for the orange portal. Upon pressing the blue button, a blue light will illuminate, and play the sound file associated with the firing of a blue portal. Once the button is released, the blue light needs to stay on, however, upon pressing the button again, it will play the sound again, without chaning the state of the light. The same needs to happen with the orange button- it turns off the blue light and turns on the orange light simultaneously, while playing the sound file associated with the firing of the orange portal. Again, pressing this button again needs to play the sound file again, without changing the state of the illuminated orange light. I currently own the toggle switch and the 2 buttons, as well as 2 rod lights designed for placement in a computer. I don't know if I will be able to cut the motherboard pin connector off and just solder the wires to the circuit. I'm assuming so.

LED sound sensitive Equaliser. How to do it?

I have this idea for a house project. I want to build a LED sound equaliser that would spread on an area of up to 40x80 cm. That would imply LED positioned at a distance of 4cm one of each other; 20 columns of 10 leads each.  I would then like to cover each separate coloured led with an opaque plastic square to give the panel the grid-like look that an equaliser has, panels that will illuminate with different colours due to the light coming from the LEDs underneath them. This (the finished panel) would go positioned under a the glass from a coffee table, giving it a rather nifty look when the music it`s playing (almost all the time).   I know what i want to do with the actual table, but i dont really know where to start with the LED panel (done some amateur electronics a long time ago, but i could say i`m at the low novice level).  Would that even be possible, having to connect 200 leds at the same time? Please let me know if there are any projects that could help me (regarding the circuit/ power supply/ recommended LEDs), and share with me any of your ideas that could help me reach my goal.

PC speakers to car speakers?

Hi everyone, I am at a dilemma, I have 2 old PC stereo speakers, and since the rear set of speakers in my car are broken, I was thinking it was an easy transplant. However, when I took them apart, I saw that these speakers are 9V, and the car ones are (obviously) 12V, so I was thinking if it is going to fry them right away, or is it going to sing for some time and then fry them OR if it is going to be just fine. Also, these are a bit smaller (65mm in diameter) than the car's original ones, and since they are a generic brand and have no wattage rating inscribed on them, I am thinking that they require less W to power. Since the car ones are about 50W and my stereo can supply 4x50W, would that cause a problem one day if i uknowingly cranked up the volume, would that fry them aswell? I am not using anything big, just a simple stereo, with a simple output, no special equipment whatsoever. Thanks ahead everyone! EDIT: I just looked and found an inscription on the transformer in the back of the main speaker: I/P 240V ~50Hz O/P 9V ~500mA That gives me like, what 4.5W? Is that each or altogether? I am thinking these are too old/weak for this :o

Field report: Mads Hobye as an Artist-in-residence at Instructables

Mads Hobye was granted an artist-in-residence at Instructables for September 2012. Instructables is a web-based documentation platform where passionate people share projects they do, and how to do it. Because of the creative nature of the website, Instructables also have lab facilities for their own co-workers and for artist-in-residences. During September, Mads had the honor to use their lab to build and document multiple prototypes to be shared on their website. I choose to put my focus on building interactive noise machines, since this ties into my PhD and my interest in creating non-trivial internal complexity. I have been working long into the night most days and it has been really interesting to have the chance to focus on one thing at the time. Although the primary purpose of the stay was to explore the potentials of designing interactive sound machines, a couple of other side outcomes were also planned. First, to see how Instructables organized their creative workspace and get inspiration for organizing the upcoming Connectivity Lab at Medea. Second, to see if Instructables would be a suitable platform for documenting the creative practices at Medea. Take aways from Instructables as a creative workspace Although Instructables primarily is a company running a website, they have quite extensive lab facilities. This consisted of a small lab at the office (sewing, electronics and woodwork) and two blocks down they had a whole space filled with laser cutters and 3D printers. This is located right beside the Techshop, which is a full-fledged lab for everything from metal to 3D printing. I have picked up the following things that struck me as really good ways of structuring lab work: Documentation table: A documentation table with lamps, camera and a white sheet of paper as background enables people to quickly document their projects with a nice white background. It was interesting to see how this improved the overall quality of the documentation. Suddenly a breadboard and some wires became a piece of art or a pedagogical platform for show and tell instead of an unfinished project. Show-and-tell meetings: Twice a week they meet at two o'clock to do a show and tell. Here they take a round and everyone says what they are working on in one or two sentences. This is a really easy way to get everyone updated and it takes no time at all. If you are not present you can email out one sentence telling everyone what you are doing. Once a week it is about the specific day and once a week it is about the coming week. Have everything in the same lab: The separation between the labs has confirmed to me the importance of having everything in the same space. It takes time to walk two blocks to lasercut which limits the creative process of iterating between e.g. lasercutting and soldering. Instructables as a workspace was one of the most easy going creative loving workspaces I have ever had the chance to be a part of. Although I never got to know the formal rules, you had a clear sense that people had the freedom to prioritise their own work day and combine it with creative side projects (as long as they documented them of course). Instructables as a knowledge sharing platform for the Medea Connectivity lab Instructables works well for sharing individual recipes for others to use, but what came as a surprise to me was the ability to create groups as individually branded websites. This enables a group of people to collect their recipes under a common theme or brand. We will use this as a common platform to share the knowledge created in the Medea Connectivity Lab. This way people can get an overview of the projects done in the lab. This will become a mandatory part of using the lab in the sense that students and co-workers will be encouraged to document their projects and publish them in the group. So far my experience with posting instructables has been quite interesting and overwhelming. Where projects normally ends as interesting portfolio documentation, the detailed documentation of the build process enables others to recreate your designs or their own versions of them. So far this has resulted in multiple people making their own version. One example is the Arduino implementation of the touche shield (https://www.instructables.com/id/Touche-for-Arduino-Advanced-touch-sensing/). This was published in May 2012. As of now, I know of ten people who have recreated the design and just as many has made suggestions for improvement. Another project has been rewritten by an enthusiast in Dubai. It now runs faster and uses less memory. You can find the preliminary group for Medea connectivity lab here. Non-trivial-internal Complexity as facilitator for curiosity = making noise machines As a part of being an artist-in-residence at Instructables, I took it upon myself to build of couple of noise machines / music boxes. My interest was in designing objects that would enable people to explore the world of sound synthesis and for me to get a better understanding of how the different interfaces enables different interactions and sound qualities. This is a part of an ongoing investigation on creating interactions for curiosity. It has been an intense experience. Trying to build as many interfaces as possible within one month. I have tried to make all of them stand-out as finished, while still being hackable pieces. Everything I have done is published on Instructables for others to experiment with. All of the projects consist of a few basic components: An interface and sometimes a screen or a led matrix. The basic sound component is either a Gameduino or a software synth written for the Arduino platform. You can find an overview of the results here and I will introduce them in this article as well. Although arduinos are good for simple action reaction interactivity, there are a limited amount of examples that work with more complex interactions. Here I mean beyond game design’s way of working with narratives, but more in the sense of adding personality to your projects. Personality not as much in the way of looks (e.g. putting an Arduino into a teddy bear), but more in the way of complex interactions that makes you curious about its devices potential possibilities. My interest as an artist-in-residence at Instructables were to design different machines that would spark the user’s curiosity. Here, simply put, curiosity lies between the extremes of chaos and predictability. Where chaos becomes uninteresting (from an interaction design point of view) because of its uncontrollable nature and order becomes so predictable that the interaction itself slides into the background of the end-product of the interaction itself. One such example is the light switch. As an adult you usually do not notice your interaction with it. The core question then became how to make people who are interacting with it drawn by their own curiosity of not being able to decode the interaction pattern, all at the same time having a sense that their actions are the main contributor to the sounds. Most of these machines would have been simpler to make as software programs on a computer or even as multitouch applications on a smartphone, but I wanted to have an aesthetic criteria as a frame for my experiments: I wanted to create simple tangible interfaces that would inspire curiosity. The objects themselves should welcome the user to try out and explore their interfaces. Last, I wanted each experiment to be self-contained. Instead of them becoming interfaces for a laptop, they should be the ones who created the music. The end results are still crude and mostly serves as interaction enclosures with future potentials, although they do hint at different interesting interaction qualities. You can find an overview of the boxes here. The singing plant plays with a classic trick of sparking people’s curiosity by adding unconventional interaction qualities to a familiar object. The Kaosduino serves as a platform to explore the complexity of touch on x-y surfaces. The Matrix machine serves as a platform to explore the potential of emergent sound patterns converted from particle systems. The algorithmic noise machine serves as platform to explore the boundaries between chaos and order through complex bit shifting algorithms. Better ways to debug the internals of the Arduino board As a side project, I decided to improve on the debugging capabilities of the Arduino platform. This was in line with working with internal complexity which can be hard to comprehend as the code grows. The program enables you to visualize realtime data on the Arduino board. You are usually stuck with the standard serial output. As the complexity of your Arduino code grows, this makes it impossible to comprehend what is actually going on inside the board. To solve this I have created a little library that will enable you to create your own custom GUI for your Arduino projects. Watch this video to get a demonstration of a basic hello world with a potmeter and a diode: The following are a few key features of the tool: Custom design your interface from the Arduino board: You define which sliders, graphs and buttons you need for your interface. You do this in your Arduino sketch which means that the GUI program acts as a slave to the sketch. All information is stored in your board. Visualize and manipulate realtime data: Whether you are making an RGB light controller or a robot arm, getting a graphical feedback is crucial to understand what is going on inside the board. This enables you to understand whether it is your hardware or the code that is causing problem. Further, the sliders and buttons enable you to tweak the individual parameters in realtime. This way you can see what effect different thresholds have on the interaction. Use the same app for all your Arduino projects: I have made tons of small apps for different projects. My problem is always to find them again a year later. Because we save everything in the Arduino, I only need to keep one app around the Arduino and it will automatically configure the app for the current project. Prototype the interface before you turn on the soldering iron: Because you can design the GUI as you like it (within reasonable limits), you can prototype the interface before you have made a physical interface. This also enables you to divide the tasks between multiple people, e.g. one person is working on the hardware and another person is working on the code. When you have made the physical interface the Guino will integrate seamlessly. You can find the instructables for the Guino interface here.

Speaker + resistor = joy? - help a mom replace a $299 6.5" OEM auto speaker

Hi All, I come to my dear instructables seeking some basic understanding.  Let me just preface this by the fact that I have no problem getting dirty or cracking things open to try to understand them better- probably  better at taking them apart than putting them back together - but I try...(hubby kids that I always end up with spare parts too). this leads me to my current problem. The right front speaker in my 2001 sienna minvan decided to blow after much to much green day playing. Yesterday I just couldn't take the awful hissing anymore and popped off the panel to pull out the speaker. I'm kinda used to my old cars where I could pop down to best buy and pickup a new set. Not so with Toyota - OH NO they have special 2.2 Ohm speakers that are proprietary to Toyota. So I went to the dealsership and was told that a new right front JBL speaker replacement  (model 6689) was going to cost me $299. - you read that right $299 for ONE 6.5" door speaker. I found a website briefly outlining how to take a plain 4 ohm speaker, get a 1.8 Ohm resistor and be done with it.  -  http://oneilengineering.9f.com/photo5.html - So there are a few questions that I need answered by someone with experience. 1) Is it that simple?  - I may opt for decent replacements and I'll do both door ones so they match ... 2) I can't see from that fellows photos exactly how the resistor is attached - is it just soldered in place bridging the two end where the + /- leads are attached? any existing ibles with closeups? I couldn't find any. is a resistor directional? 3) I read somewhere that if I'm adding the resistor -  that heat will be generated from reducing the current - Is that true? if so - do I have to shield it somehow? Thank you for any help !!!

Leds with sound sensor and motion sensor? Answered

I'm planning to use an arduino uno to control 16 white 10mm leds that light up according to a sound and motion sensor. I'm planning to place them in a cloud and make the leds respond to thunder sounds. What sound and motion sensor do you recommend?
