Computer program learns physics

From Wired:"In just over a day, a powerful computer program accomplished a feat that took physicists centuries to complete: extrapolating the laws of motion from a pendulum's swings.Developed by Cornell researchers, the program deduced the natural laws without a shred of knowledge about physics or geometry. ...Condensing rules from raw data has long been considered the province of human intuition, not machine intelligence. It could foreshadow an age in which scientists and programs work as equals to decipher datasets too complex for human analysis."LinkThe software has a long way to come, but apparently it's showing a lot of promise.What do you guys think? If computers can do physics better than humans, does that make human physicists obsolete?

Survey on Physical Computing and Microcontroller

Dear user, I need YOUR help in order to get some insight into the substance of microcontrollers and physical computing. The basic question that needs to be answered is, what the problems are that occur in the process of physical prototyping, what the reasons for these problems are, and how these problems can be avoided. The results will be used in a bachelor thesis, that deals with this topic, trying to find out how easy - or difficult - it is to enter that particular field. I kindly ask you to follow the following link and to participate at this survey. http://www.kwiksurveys.com?s=NJDNHK_210fb8e2 Thank you very much in advance!

Graphical User Interface Library for Physical Computing in Processing

Visit our blog:    http://blog.butterflui.org/?paged=3 The subject of physical computing, especially in the field of robotics, is a fascinating area that has already begun its triumphant in universities, schools and hobby applications and is developing with impressive speed. It is highly interesting that Pyhsical Computing and Robotics, more than any other area, can merge many different areas (engineering, design, psychology, biology and many other areas). Our target groups are mainly users with robotic and physical computing affinity: engineering, programmers, mechatronics engineers, product designers, interaction designers, communication designers, robotics, interface designers, developers, electronic engineers and artists. There are people who want to monitor and control the input and output of their system without major effort in which they rely on an interface library. Robot experiment sets are increasingly being used in short-term projects in schools and universities to provide basic knowledge on physical computing. Our analysis of current sets shows us that existing features don’t cover all aspects of robotics. The aspect that has been neglected so far according to our research, is the controlling and monitoring of experimental physical computing projects through a graphical interface.

3D Domino Physics Simulation!

Just for fun, I made this little video. And these What do you think?Anyways, I made that using a Physics simulation DLL for Gamemaker.Rendered and everything on my Computer, I got Framerates a bit lower than 1(what do you expect with over 1000 Dominoes?), But the recorded video output is much faster than that.Enjoy!

Physical Space Installation Game

Looking for people who are interested in helping out on the electrical engineering side and/or set design of a installation game. Various people in the industry (theme parks and video games) should stop by during the exhibition and credit will be provided. On the electrical side it would be helping out with networking of Arduino boards to run each "gag" and be linked into a show control. On the set design side - help with the set design of the piece, lighting, and construction. The installation will take 3 players and have them "break into" a vault with various high tech security (lasers, pressure sensors, computers needing to be hacked, etc). Other examples of this type of work would be "The Tomb" and "Operation Spy" by 5wits, La Fuga by Negone (in Spain), interactive haunted houses, and theme park attractions. Message me if you have any questions. Thanks!

Omniversity : Beginners Guide to Arduino & Physical Computing Workshop

We're launching the Omniversity, housed at the Manchester Digital Laboratory. The MadLab has been one of the country's most successful hack and creative digital culture spaces, attracting thousands of visitors to the region and bringing in national and international talent to lead free workshops and events. Every evening is double-booked with free community-driven events around open platforms and professional development. Building off the back of this success, and the huge network we've built, we're offering the Omniversity - an expert-lead series of training programmes, designed to be affordable and lead by industry veterans and in-the-trenches professionals, rather than full-time tutors. We'll be teaching people platforms from the near-future, without the cost overheads that more formalised training providers impose. This brings us nicely to the course of the Beginners Guide to Arduino & Physical Computing... Physical Computing’ and Arduino devices have made physical interaction affordable and available to non-experts. Whether creating interactive installations, information systems, prototyping products, or making new interfaces, there is a whole world of DIY electronics, interaction design and rapid prototyping available through this platform. But what can you do with an Arduino? Here are some of our favourite projects using the Arduino- Joe Saavedra's SOBEaR, the responsible robot bartender, Sosolimited’s HBO Snow Window, & last but not least the MadLab/HACman collaboration : Project-A-Sketch To find out more & book onto the course please see here > http://omniversity.madlab.org.uk/booking/?regevent_action=register&event;_id=7&name;_of_event =Beginners+guide+to+Arduino+and+Physical+Computing Hope to see you soon!

How to connect physical pushbuttons to a computer for use in a soundboard program?

I plan to do a project that will use 28 arcade style pushbuttons to activate 28 different sounds on a computer. Any ideas on products out there I can use to connect all 28 buttons to a computer, preferably with a USB cable, so it can be used in a programming language such as C++? One idea I had was to take apart a QWERTY keyboard, but I still want to be able to use my regular keyboard to use my computer. Alternatively, is there a way for two keyboards to be connected to same computer, but one of them only activates a specific program? i.e. trying to type in notepad with it wouldn't work?

See What's Really Happening in Physics -- arXiv.org

If you are curious about what "real physicists" do, or what the current "hot topics" in research are, take a scan through the "recent postings" at the Physics Preprint Archive. Started for the High Energy Physics community in 1991 at Los Alamos National Lab under the name xxx.lanl.gov, and with a purely e-mail interface(!), arXiv moved to Cornell Univerisity with its creator in 2001.The archive includes preprints from all areas of physics research, not just HEP, as well as computer science, mathematics, and quantitative biology. "Preprints" are a way for the research community to get their results out for everyone to read, during the often lengthy period (months, sometimes!) between submission to a journal and actual publication. In many fields, it has been traditional for decades that printed copies of "preprints" were mailed out, sometimes in regular batches, between major University departments. That mechanism has been superseded almost exclusively by the arXiv database.Besides these traditional pre-publication journal articles, the archive also often includes conference proceedings, and submission of much older published papers of general interest to the community. There's also (usually in the general "physics" category) a scattering of crackpot nontraditional science papers.

How could I convert a physical book into an ebook?

I have some books that I would like to make into ebooks so that i can carry them around and read them more conveniently. I would prefer not to use a scanner, partly because mine is not very good and also because a few of my books are somewhat fragile and I do not want to damage the spines on them. I do have a very nice digital SLR camera if there is something I could do with that. thanks for the help

Using a computer fan to lift a solar cell

Hi! my boss told me to come up with a cheap replacement for a vacuum pump and since it's needed to lift only two solar cells at a time, I thought a fan could be used to create negative pressure. The cells are really light, but since I suck at physics/fluid dynamics, I thought I'd ask if I'm way off base and if I am, is there any solution to this problem. I attached a picture of the current state of the idea.

How to make a laptop LCD monitor connect to another computer as a normal monitor (physically)?

 Hi, I want to create an overhead LCD monitor projector (from instructables on here). I do not have an LCD monitor to take apart. However, I do have an old laptop monitor that works and would like to use the screen on that.  My problem is, once I take it apart, the cable that connects the monitor will not be compatible with a standard video cable like a regular monitor would be.  Is there any way that I could use this monitor as my overhead projector. Like, is there some sort of converter or thing I could attach to the cable to turn it into a standard monitor that I could connect to a computer's video card.  Thanks for any help, I've looked around and haven't found anything.

Anybody want to model "reflux" in the circulatory system? Physical model or computer pipe model!

My wife just had an amazing success when we went down to Newport Beach, California to get venoplasty to relieve many of  her symptoms following a stroke.  http://www.youtube.com/playlist?list=PLkzXlmAwZTZfQ01RnN-8Ip5lUz0HrNWzN  We pay for national medical insurance in Canada and this treatment is not covered.  (Even though it clearly works, )   One road block is that an expert doctor here could not find any evidence of reflux in blood flow to or from the brain.  (Some MS patients have damaged valves in their neck veins).  Now, given that each heart beat raises blood pressure from 1.5 psi to 2.3  psi about once every second and that valves are actuated by the blood flowing backwards, I find the "expert doctor's" results impossible to believe.  I am not totally without knowlege in that area either because I made a low pressure airlift pump this year  that has a much higher lift submergence ratio than the normal ones.  (The airlift in a bucket one). I was told that the maximum  lift to submergence in these things was probably not much more that 10 to 1 but I managed to get over 20 to 1 lift to submergence primarly by reducing reflux.    Also, I observed that the effects of this reflux can extend conciderable distances from the "valve" itself and are different in small tubes than in big tubes.  Therefore it is possible (Likely even) that a damaged valve in a persons jugular will have its primary effect in a capallery somewhere in the brain up to a foot away from the damaged valve.  So if someone made this model, I think it is likely that they can contribute to the rapid advancement of medical science!   Brian White

Should I stay with engineering?

I am currently in the 2nd semester of my freshman year of college (University of Northern Iowa) as a physics major. This fall I am planning on transferring to Iowa State for computer engineering but I am starting to have second thoughts. I have always liked learning about technology and building projects (currently robots) and I can't imagine any major other than engineering. I got a C in calculus 1 and physics 1 and am currently taking physics 2 and calculus 2. Physics 2 should be fun (finally get to electricity and circuits) but I am worried about calc 2. I've never been a math genius; does this mean I'm in the wrong major? I guess I am looking for some advice on if I'm in the right major.

Is it possible to produce a sound wave that makes us experience silence?

What I mean is: a computer or whatever produces that sound and we can't listen to anything, not even our own speach. That would make us experience TOTAL silence. Is it physically possible? That would rock. :) Thanks, Pedrotome

Convenient djvu to anything readable conversion?

This is a problem I've been trying to solve for the last few weeks. I've finally been given a kindle (New Year presents), and it is great not to have to carry three or four books to school every day - usually it was the thing we read in Literature, some novel I read on my way in the underground, some Physics I have to read and understand and some Physics to help me understanding the first lot. It's been doing a great job, except for  not liking in the cold and getting a bit mad outside, but most of the Physics books I have and can find are in djvu for some reason known only to people who made books on Physics and Maths, so they can't be read on it directly. Is there any way to convert the books to something readable, and better not pdf, because it shows really slow and small and moving around the page is very unnerving especially early in the morning... I'd also love to save the pictures. Any ideas?

Resource regarding Electronics

Hello everyone, this is kaatan. A new member of instructables.com with a question which I seek for a very long time. With good resource in Computer and Programming I've mastered Computing skills and Info Security (BTW I'm a Computer Science Student who is Admin of a under developing site). But I'm not satisfied with my skills and I wanted it to be extended for robotics. I knew that I need some Physics, but that is not a problem at all. All I need is a good book for beginners on Electronic devices, which will provide me with in depth explanation and easy to understand and do projects myself (I'm more enthusiastic to learn). Anyone with this resources similar to this please share with me or if you need any doubt or resources ask me :)

Modem with one ethernet port, have two units to plug in?

I have a Motorola SURFboard SB5101U cable modem. It has one Ethernet port and one USB ("square" type) port. I have an Apple Airport Express wireless plugged into the Ethernet port.  Here's the problem.  I want to use "MagicJack Plus" (VoiP) without plugging it into the computer (THE difference from the "regular" MagicJack, that it (the Plus) can be plugged directly into the modem, bypassing the computer, so the computer doesn't have to be left on 24/7 for your phone service).  My question is, can a simple Ethernet (pigtail) splitter be used to plug both the MagicJack Plus and the Apple Airport Express wireless into the modem?  I know this can be "Physically" but is the "signal" degraded in any way to the two units?

How does a computer "write" something... to memory, a registry, etc...? Answered

I know that every computer has a CPU. I know that every CPU has it's own Instruction Set, or... set of things that it can do: CompareAddJump toInOutetc...I even know a fair amount about how a CPU interacts with RAM along the Data Bus and the Address Bus with Set wires etc, and how a CPU's ALU (Arithmetic Logic Unit) stores data temporarily in "registries" and uses "flags" to send things back to the Control Unit if the CPU. So, I know a fair amount about "How a computer works." But... it is all theoretical. I have memorized words and ideas like "ALU" and "Registry" and even RAM. But there is one thing that I do not understand and cannot seem to find anywhere on the internet. The verbs "write" and "store"...??? I know that a record cutter uses electrical current spread across metal plates with magnets that push a scoring tool into a soft "scratchable" medium to cut a long groove to make a record. Then a phonograph has a needle that that is likewise suspended between electrical currents with magnets that telegraph the grooves up a wire to replicate the sound through a horn (later a speaker). But as far as I know... RAM or a CPU's registries can have binary "words" somehow written to them for storage. I know it is happening at 3-4 billion times per second, but even if you slow it down to one time per minute... how does a CPU "write" 00110100 to RAM? There are no magnets in RAM like on a hard drive. RAM has no physical material that can be changed to represent a zero or a one... like... wax, or vinyl, or magnets. I don't even know who I can ask this to... so I'm asking here.

efficiency (not efficacy) of CPUs/computers? is all the power input technically converted into heat? Answered

It has recently been fairly hot where I live, especially in my room, where computer hardware seems to be increasing the temperature by a good 5-10*F over other rooms. This got me thinking, and was wondering if any computer engineers/physicists may know the answer to this one. If I am running a power-hungry intel CPU, coupled with RAM and maybe SSD storage (I wish!) is all the power fed into my system being converted into heat? In other words, if my rig consumes a good 250W-400W, and there are no transducer devices drawing power (LEDs or lights, speakers/microphones, monitors, motors, heaters, phone chargers, etc,) and all the energy is used for data collecting, and calculating, then is *ALL* the energy converted to 250W-400W of thermal energy (heat)? or do the data operations themselves in fact require energy and maybe entropy or something plays a role? where it would seem that 400W of input yields an apparent 399.981W of energy output + data.

Assistance with Windows Vista, why can't my computer recognize analog outputs/sound does not work?

Okay, I have an HP Pavilion a6110n desktop computer, running Windows Vista ,Service Pack 2. A few days ago, I had the power supply fail, and had to replace it. After that, I noticed that my computer would not play any audio through any of the 3.5mm analog outputs. When I go into sound manager, the computer tells me that the speakers/audio outputs are not plugged in, even though I opened the case and confirmed that they are plugged into the motherboard. In addition, the onboard Realtek HD Audio Manager will not recognize any output other than the digital output, even though most of the analog outputs are integrated into the motherboard itself, and not a separate audio card. I have tried Googling to no avail, as none of the solutions I have tried have worked.  I have tried updating drivers, adding and removing hardware, uninstalling and reinstalling Realtek, even updating the BIOS, all to no avail. I have tried calling both Microsoft, and HP, and they are both unable to help me without me having to pay them. Since my computer is so old anyway, that would not be worth it. Basically, is there an easy solution that will not require me rebuilding my computer? If there is not, I won't even bother. Also, I've tried disabling, then enabling the speakers, from the sound manager, but that does not work either. If there is any possible way to help me with this, i would appreciate it. Thanks in advance. PS I've also included the two audio manager screens I get, hopefully showing the problem better. Edit: I've tried looking at this in Safe Mode, and it gives me a Code 45, basically telling me that the software is physically not plugged in. I'm seriously wondering why my computer can say that, even though the hardware in question is part of the motherboard. Also, if this were a problem, where would I look for blown capacitors?

how much ram does a palm zire 31 have? is this the ram chip? Answered

I know that i get 14mb for storing data, but what i want to know about is the actual physical ram, like in computers, that determines how well applications are run. i know it has a 200mhz ARM processor, but as far as physical ram memory i dont know if it has any at all. i have located a BGA chip that looks similar to those found on ram cards and video cards, and i have one that i pulled from a old laptop, which is 64mb. (it had a 256mb integrated video card) i think it might have 32mb, i had a application called UDMH that allocated more ram so yuo could run applications like LJP (a nintendo emulator) so, is this chip the ram chip?

Best way to host svg, stl, source code, other files for an Instructable

I've got several Instructables that explain how to move from a computer file (3d model or Illustrator file) to physical object (3d print, laser engraving, etc.) I would love to be able to put a link to those files in the body of the Instructable itself, so any reader could download them and use them freely. Similar comment for code snippets; inline code works (with careful editing) but it isn't optimal for longer bits of code.

Taking an Open-Source Approach to Hardware - Instructables in the WSJ

The Instructables Arduino contest gets a mention in the Wall Street Journal's Taking an Open-Source Approach to Hardware. Open-source hardware applies the same idea to physical things. There are a number of recent open-source hardware initiatives, including the Chumby, a clock-radio sized device that runs software "widgets" to display the weather or stream music, and Bug, a system of snap-together modules that can be used to make a variety of computing devices. So far, the Arduino has been the most successful. In the space of an hour, a layman can make it blink an LED, run a motor or send a temperature reading to a computer monitor. With a little practice, people have been able to do much more. Using Arduino hardware, tinkerers have recently created everything from a word clock to a radio-controlled lawnmower for a contest hosted by the Web site Instructables.com. More news and press about Instructables here.

Need to make a guitar-to-3.5mm cable with the following material

I have only a limited amount of resources to utilize in this project. I am still a rookie when it comes to physics, so I decided someone here might help. Please also note that I cannot get any additional material because it is not available locally and Amazon/Ebay don't ship to my address. I currently have the following materials: -A cut headphone's wire with a 3.5mm  output at one end, and three wires (green, blue, golden mixed with green) at the other. -A wire with the colored outputs (which you plug into a TV) at one end, and a 3.5mm output at the other -A 3.5 to 6 mm converter -Standard guitar-to-amp cable I can connect both wires to the computer and guitar, but what connection would there be in between? I don't have 6-3.5mm converter; thats basically the problem.

Copenhagen or Many Worlds Interpretation?

Which interpretation of quantum physics do you prefer? Personally I favour the Many Worlds interpretation as it better explains how the particle 'chooses' what state it collapses into, whereas when I consider the Copenhagen interpretation, it makes me think that the particle is deciding, which bothers me, obviously. However, the Many Worlds interpretation throws up many issues, such as the problem of probability (if a universe is created for every possible outcome, the probability of anything is 1, including say, your computer randomly exploding now). Which is quite ridiculous. But still, to me, a better explanation. So your thoughts?

Finding the altitude of a ball using weight and time airborne

I was shooting my tennis ball cannon today, and i was wondering if there was a way to find out the altitude of the ball using the time it was airborne and the weight of the ball. I have no idea how to approach this, i dont know of any math formulas that we've learned so far that can compute this. I think it would have to factor in drag, gravity, the weight of the ball, and how long it was in the air. I just dont know how to do it. If anyone with a better understanding of physics and mathematics can help me out, or point me in the right direction, it would really help me out! thanks!

searching for a pump that can handle pudding

I dug through a few forums, trying to decide which this was best suited for. I settled on tech since its a physical computing project. I'm looking for a resource for a water pump that can handle something like pudding. the initial thought was use an air pump and a bag or maybe have the bag be squeezed closed but i need it to cycle through.  Like a water fountain of pudding! The pudding spurts out, then there is also an intake which is recycling the goop. Does anyone have a resource on pumps which could handle something so thick?  (and since its a small scale project, cheaply and small!)

Mechaniical vs Electronics special course?

I am not going to take a whole college course as I have finished Bs in Computer Science already I just want to explore more and create things that are physical or hardware that I can program, I just wanna explore the possibilities I have and be able to create, what courses should I take? I am willing to study anything just not the whole college semesters again I just need the major subjects or workshop that I can attend with hands on.  I am more of a self study person so a very good fundamentals of basics of gears circuits that works well with a program should do so Ill have a smooth start.

How to view corrupt zipped files? Answered

The problem is that I need to recover a zipped file from a corrupted hard drive. The hard drive is NOT physically damaged, only inaccessible due to the current state: I accidentally, began ghost imaging and completed about 10% of the initial process before I canceled it. So now the system won't boot. I get a single flashing cursor in the top left corner of the screen. If I connect the hard drive to a SATA-to-USB adapter and connect it to my Windows XP computer it will show that the 'Mass Storage Device' is found and installed. But I can't see the device in My Computer or Disk Management. What I think needs to be done is have the device (connected via USB) mounted so that I can use a file recovery program to scan the drive for files. Does anyone have any ideas? I know I can complete the reimage and then try to recover the file but its about 2.6 GB in size and I have a feeling that no programs will be able to successfully recover the whole file. I would like to recover the file without reimaging the drive because chances of the files being overwritten are much greater if the image completes.

Actuated Matter Workshop / Zurich / July 25-29

APPLY NOW !!!! http://blogs.iad.zhdk.ch/emotiveenvironments/actuated-matter/ The Actuated Matter workshop explores the application of smart materials and their ability to transform space into responsive, adaptive environments. We will develop a speculative model for membrane structures that exhibit properties of sensitivity, resilience, and decay. By physically engaging with the behaviours of active materials, we experiment with the threshold between the electronic and mechanic, the analog and the digital. The workshop follows a do-it-yourself approach and will result in the development of sonic, luminous and moving modules that will populate and activate the environment. This workshop is part of a recent research initiative called “Emotive Environments” and emerges from a collaboration between ZHDK's Institute for Computer Music and Sound Technology (http://www.icst.net), the Interaction Design Institute (http://iad.zhdk.ch), ETH's Chair for Computer Aided Architectural Design (http://www.caad.arch.ethz.ch) and London based Loop.pH Design Research Studio (http://loop.ph/). Participants will work in small groups, each be led by someone with experience in the particular field of research. The workshop will be complemented by a final presentation and unveiling event, where you are also invited to come see the results, if you cannot attend the workshop. The workshop is free of charge. Application forms and more information can be found at: http://blogs.iad.zhdk.ch/emotiveenvironments/actuated-matter/ APPLICATION CLOSES JULY 13

HELP for using SPDT relay to turn on toy

Hello All, I'm new to physical computing and have a question that's probably very easy and yet I can't figure it out. I have a doll that cries or laughs depending on which connection you make (if you press the left side it cries, right side it laughs). I want to hook it into a bread board and then control when it cries or laughs with arduino. My teacher said I need to do this using a relay (its the big black one, I believe it is a SPDT). He gave me the schematic that I've attached here. From what I know the relay has 8 pins. according to this sketch I need to connect the 2 pins furthest away (nothing near them) to a diode and 5Volts. But- what about those other 6 pins? What do they attach to? Any help would be great! Thanks

Are Science and Engineering skills are required?

First of all, hi everyone, I'm new to the forums and this is my first post so bear with me if my questions are strange! I've been taking glances at the projects in Instructables, and I am really happy to find a site that shared my passion in home science/technology/DIY projects! I am studying Physics (first year) at my city's University (Aristotle University of Thessaloniki, Greece) and I was always fascinated by science, technology and especially computers-electronics. Instructables' projects 'pushed' me to get some basic tools (A 25 W soldering iron, a soldering pump, a pair of 'helping hands' with a magnifying glass, screwdrivers, wire cutters, wire strippers, some other basic tools and recently a Dremel 300) and frequently, I've been trying some of the simpler projects. But, since science will be my future profession, I'm not content by just reading instructions and following through...I want to understand the principles behind the instructables (for example, electronics) and even make my own small projects at home. As I said, electronics/electrical engineering projects are kind of my favorite, and I often get frustrated by just blindly following through the instructable, and I ask myself 'how did he think about that' or 'how did he know how to build this circuit' or 'how did he choose his materials'. So, do you really have to be an engineer to plan the more advanced -electronics or not- projects or can anybody get a book/website and learn about those skills? I often get ideas about projects of my own, but I don't know how to choose materials for them...does this skill come from experience or gained by an engineering degree? Is Physics a good enough degree to help me with my projects? And another question that has been around my head for a while: do you actually get pen and paper, lay down designs and scientific formulas-calculations to build a more advanced project? Thank you!

HAL 9000 Open Source Community Project - Announcement and Invitation

Goal:  Build a HAL 9000 Series Computer Specification:  "2001: A Space Odyssey" Website:  www.hal9000project.org Instructable coming soon I watching "2001: A Space Odyssey" the other night and I decided it would be cool to build one.  I've never managed a project this big, and don't plan to start doing it now, so hopefully people will step up and assume various roles and responsibilities.  A project like this needs a program manager, deputy program manager, project managers, systems engineers, software engineers, programmers, graphic designers, web developers,etc.  I'll assume the role of chief engineer and chief software architect.  Also needed are an admin for the sourceforge project, and a webmaster for hal9000project.org.  I don't plan on having any special rules or regulations, I'm just throwing this out there to see what comes of it.  It could end up in a hairball of chaos, or it could evolve into a smooth running machine, although I suspect nobody will join in and it'll be just me with nobody watching. This is not a far fetched pipe dream.  The IBM Watson has already beaten the reigning champion on Jeopardy. I'll be defining all the individual subprojects such as the speech recognition function, lip reading function, speech synthesizer (it will have the exact voice used in the movie,) facial recognition function, voice recognition function, object recognition, various other artificial intelligence functions, neural network, physical mockup, physical prototype, software simulation, etc. There is a distinct possibility of getting government funding and along with commercial grants, therefore, some people could theoretically carve a full time job out of this.  That would work for me.

How would I go about building a portable battery power boom box with 2 tweeters and one large woofer.

Over the Christmas holiday I would like to utilize two tweeters that I obtained from computer speakers and a subwoofer that I obtained from a surround sound system to use in a portable battery powered boom box.  The goal is to makee the whole setup rechargeable (thought about solar panels also, but baby steps) with a usb slot (power only) to charge ipods/iphones and a single aux cable.  I have been experimenting with each of the speakers and I have an idea of what size of box I am going to have to produce the best sound, tips on this would be welcomed as well.  Strong deep bass is a major goal of the boom box as well.  Physical volume controls are not need.  The only button I assume would be for the power. Any tips or suggestions are welcomed.

Magnetic accelerator coil Answered

Im going to try to keep this short. So a friend and I are both sophomores at our highschool and we are both in chemistry (which is a higher level science) and i built a coilgun for last years project and attempted to build a PWM driven one this year. My friend and I want to build a rather large coilgun using either 10 microwave oven caps or close to 40 or 50 caps from computer power supplies. What i need help on is whether we should use the microwave caps which are high voltage but low capacitance or the power supply caps which are 200 volts and around 500 micro farads. I also need help on what wire to use for my coil and how many turns for the coil. i would like help with a coil for each cap size. We are planning on using either a 3millimeter by 5 centimeter long steel rod or a quarter inch bolt. our goal is to at least shoot it through the wall of the physics classroom and maybe through the door of a car. anything helps. Thank you

more powerful, portable amp

I was messing around with some op-amps, building variations of the CMoy amp, etc. But I became depressed quickly -- these ICs' data sheets say that at the safe maximum of 15 volts, they can only pump out around 1/4 watt of power on a single channel! Well, i have a full range driver that really needs more power to sound decent. I was wondering what the normal way of constructing an amp would be if I were looking for 5 to 10 watts of power. *edit*: i'm not looking to run this thing off of batteries... i'm sure at 10 watts, a couple of D cells would get drained rather quickly... I recently cracked open an old 4.1 computer sound system (by microlabs) and scrapped the 5 drivers (4 satellites and a 5 inch sub), two big 3700 uF caps, and two JRC4558D dual op-amp ICs from the amplifier. I read up on the JRC chip (actually, just the data sheet from the RC5448D, the texas instruments flavor, i guess the JRC is discontinued) and it seems that this thing only puts out a max of 200 mW per channel, and typically around 90 mW. Ok i know those speakers didn't get THAT loud without distortion, but i am CERTAIN it was more than 800 mW for those 4 satellites. I am a new computer engineering student, so i can understand the physics behind the electronics, but i am nowhere near the level to start reverse-engineering that amp board. So how did these speakers get driven so hard? THANKS for reading!!!!!

What is Kelseymh up to?

CELEBRATIONS have just finished at the Brookhaven National Laboratory in Upton, New York, for the 50th anniversary of a milestone that had nothing to do with basic physics research. In October 1958, nuclear physicist William Higinbotham created one of the world's first video games, called Tennis for Two.Officially, his goal was to liven up displays at the lab's annual visitors' day, and in that he succeeded. Hundreds of people lined up to bat a glowing spot back and forth across the video screen of a common or garden laboratory oscilloscope.Unofficially, Feedback suspects he was really just goofing off on a slow day, or waiting around with nothing to do when the lab's particle accelerator was broken, being maintained or otherwise failing to deliver the goods. Higinbotham himself said the idea came to him while reading the manual for an early computer which could plot the course of a missile or a bouncing ball on an oscilloscope screen. He then designed suitable circuits and control boxes - Stone Age versions of today's joysticks - so that two players could bat an electronic ball to each other across the screen.The game was adapted for a larger screen, but eventually forgotten until 1982, when Creative Computing magazine heard about it and thought it might be the first video game. With the invention far enough behind for him not to worry about accounting for time wasted on the government payroll, Higinbotham claimed credit for Tennis for Two.Such primitive video games are old hat now, but hundreds of physicists including our own Kelseymh are still waiting for the completion of repairs to the Large Hadron Collider at CERN. What might they be inventing this time, while sitting around twiddling their thumbs?New Scientist Article.Tennis For Two Simulator (untried by your correspondent)

Maker Movement Gaining Recognition

Tim O'Reilly has some really nice things to say about Instructables and our community of people building things and doing it themselves over on the O'Reilly Radar post Maker Movement Gaining Recognition.In addition, what today is "do it yourself" is tomorrow's big business. The hacker building homebrew robots shows us something about the future of robotics. The crafter incorporating technology into traditional crafts shows us something about how computing is becoming pervasive. The folks playing with laser cutters and 3D printers are telling us something about the future of manufacturing. The folks hooking up sensors to tie physical buildings to their analogues in Second Life are telling us that the future may not be in virtual reality but a new kind of augmented reality.For a long time, Tim has had success identifying trends by looking to hackers to see what they're up to and how the problems they're solving will soon become mainstream. So, what problems are you working on right now? What's you're next Instructable that's poised to go mainstream?(The image is from our July Show and Tell.)

How do you make a 12x1 LED Matrix?

Hi everyone, I'm completely new to this site as well as DIY projects so I would love some help on a uni project I am currently trying to start. My idea is to make an abstract clock which only contains an hour hand only and the clock face itself will rotate to tell the hour. The hand will be made up of a 12x1 LED matrix. Each light is supposed to represent each 12th segment of the clock and will light up when it is past that segment in time. For example, at 3:15, the clock face will have rotated so the hour hand (that always points up) points on the 3 and 3 out of 12 LEDs will be lit. This has to be programmed with an Arduino. Being new to physical computing etc. I am so stuck on how to even begin this project! If anyone has any ideas of how I can begin this please let me know! Or just help me get started by telling me how I can make a simple 12x1 LED matrix to act as the hour hand. I look forward to your replies, many thanks everyone!
