How not to write complaints

As I see comments complaining over certain aspects of projects often enough, here is why some of these quips are utterly futile in their nature and go unacknowledged by many. Here's one posted a few days ago: "It's confusing for people without a technical understanding." This comment was posted to an instructable with 17 steps and several dozens of photographs. Because there is no indication of what the problem is, this statement is all but meaningless. There is nothing on which to base a response with help tailored to the commenter because he has not explained his plight's origins. If you are going to make a complaint or ask a question, identify the relevant subject. That will grease the skids for any correspondence that follows. Without it, your bid for a chat is more complex needlessly.

​By the nature of my work, I have to prepare daily reports in MS Word format.

But the last time I unsuccessfully edited the report directly on the flash drive, and this led to a terrible problem for me and my work. Now the interface shows me only about the error when opening. There is nothing more to do with the document. It is important for me to solve the problem earlier than technical support will do. I need lost information to continue working without loss of business reputation.

linux on polaroid pmp350-4 mp3 player?

I am trying to re-flash and put linux on this mp3 player. The ultimate goal is full sound and photo/video support with touch screen interface, using an alternate OS other than the one provided by polaroid. I would like to use this to read text documents as well. ---- --- I was going through some of the old gadgets in my house and found that I still had an old polaroid pmp350 mp3 player. It has a touch screen and I thought to myself "hmm... google android..." or "rockbox..." This is a cheap peace of hardware, and even though google android is out of the question, I was wondering about flashing it with custom firmware to allow it to run some other operating system. It has a touch screen which would make it quite fun to play around with if only there was a way to expand its current capabilities. So I thought I would put up this thread to see if somebody more clever than I could figure out how to re-flash this thing and install linux, OR if somebody could point me in the direction of materials that might be used to do such a thing. The main issue is going to be getting an OS to run on this unsupported hardware. I am going to be doing research in the meantime to find out how to get linux on this device, because I think it would be a really cool hack to show off to friends. *Update* Have written polaroid for info regarding technical specifications, also asked if they might be able to provide a rom flashing tool* If anybody wants to give this a shot, let me know how it turns out. Peace and love.

"Bug" - Issue with image importer converting .PNG files to .JPEG

Update: posting this topic further illustrated that something weird is happening with how Instructables handles images. The image as shown above shows both left and right sides with the text blurry. If you click on the image, the left stays blurry (as it should because it was) whereas the text on the right shows clear and sharp. I give up on the root of the problem, but it's frustrating how the image quality gets messed up.I put "bug" in quotations since you never know if it's a bug, unintended side effect, technical limitation or external problem. I'll let Instructables be the judge. Regardless, I thought it might be worth bringing attention to since I'm probably not the only one to have experienced it.While I use RAW images converted to JPEGs in Lightroom for my main project images, which tend to look beautifully, I normally use Canva to design my title images. Mainly due to being able to add text, shapes or any other elements in layers. Canva exports by default in .PNG format, which is probably the most popular image format after .JPG due to its support of transparencies and lossless compression. For that reason it's normally preferred for header images and graphics. I tend to use a ratio of between 4:3 and 16:9 to make things easier for the file uploader, as well as a longest edge of 1024px since that looks like it's what Instructables wants so it won't be resized. Despite trying to make things easy for the uploader, my title images have always been the blurriest, noticeably more so than the rest of the images or the image uploaded. Today I finally did some tests and found out that on import of .PNG files, the uploader noticeably deteriorates the quality of the image when converting it to JPEG, even if it isn't resizing it. A picture is attached as evidence. It seems to particularly affect portions which are highly saturated or text, greatly desharpening it. It makes a good image look like it's been carelessly edited. For the image to maintain its quality, I have to take the original .PNG and convert to .JPEG on my own (Photoshop), and then upload the .JPEG to Instructables (instead of the .PNG). As a user, what I'd optimally like to see done is: Fix the importer to properly support .PNG images without deteriorating the images. It is way too popular a format to not accept. I do realize it might be a Canva color space or other such issue, but it probably wouldn't be limited to that program anyway. Nonetheless, if this isn't possible, I'd be happy for the system to simply not accept .PNG and to throw-out an error message telling me to convert the images on my own and only upload .JPG. That would at least avoid image quality being inadvertently affected. Make available an up to date FAQ page where all information regarding images is available: what formats are natively accepted, what is the optimal ratio for images, what is the optimal resolution for images, to what sizes an image is resized on import, or any other relevant technical image details. I've researched this multiple times in the past and there are a lot of people with the same questions in the forum. Especially when it comes to sizes and ratios (cut off images, etc). Most of the information is from years ago (ex. 2010) and cannot be trusted to be up to date. Up to now I've uploaded plenty of 18 megapixel images when it is unnecessary given that the largest size shown, I think, is "LARGE" size at 1024px (I believe). A place to educate ourselves objectively on this particular site's preferences would be appreciated.Anyway, thought I'd comment this since it was a relief to finally find out the origin of the problem.

Agilart project: the visual way of programming microcontrollers from your browser

Hi all, about an year ago we faced a problem with a microcontrollers and how difficult were for us to use them in a simple home solar system. That was the reason to start our project Agilart (www.agilart.com) with the idea to make a simple web based program designer, where we can visually program the microcontrollers.  Now we have the site (www.agilart.com), a short demo video of the idea (http://www.agilart.com/community-and-support/video-tutorials/agilart-getting-started), and a few blog posts where we have tried to give some more details about the project (http://www.agilart.com/blog). We also made microcontroller's part and open source project (http://www.agilart.com/blog/agilart-runtime-in-github). We have plans for open hardware project for microcontollers designed especially for Agilart and providing features on prices under Arduino with Ethernet shield. But why I'm telling you all this? Because we need your feedback and help. We would like to ask you to share what do you think about the approach we propose; what do you think about programming using block-diagrams; do you think you can use such approach yourself; do you need such tool or you prefer programming? This will help us test our hypothesis, to check whether what we think will be useful is actually useful or it is cool only in our heads. This will help us understand does it worth to go further or not. Our vision about Agilart is to provide an easy and intuitive way of working with microcontrollers even from people without technical background. We see it as open source/hardware projects combined with some paid services to cover R&D.; So, thank you for reading this and I will appreciate any feedback from you. Thanks in advance for your time. Ivan Dragoev

Free NASA Software!

From the NASA press release: NASA has released its 2017-2018 software catalog, which offers an extensive portfolio of software products for a wide variety of technical applications, all free of charge to the public, without any royalty or copyright fees. Available in both hard copy and online, this third edition of the publication has contributions from all the agency’s centers on data processing/storage, business systems, operations, propulsion and aeronautics. It includes many of the tools NASA uses to explore space and broaden our understanding of the universe. A number of software packages are being presented for release for the first time. Each catalog entry is accompanied with a plain language description of what it does. “The software catalog is our way of supporting the innovation economy by granting access to tools used by today’s top aerospace professionals to entrepreneurs, small businesses, academia and industry,” said Steve Jurczyk, associate administrator for NASA’s Space Technology Mission Directorate (STMD) in Washington. “Access to these software codes has the potential to generate tangible benefits that create American jobs, earn revenue and save lives.” NASA published the first edition of its software catalog in April 2014, becoming the first comprehensive listing of publicly available software to be compiled by a federal government agency -- the largest creator of custom code. Since then, NASA has shared thousands of its software programs with students, industry, individuals and other government agencies. “Software has been a critical component of each of NASA’s mission successes and scientific discoveries. In fact, more than 30 percent of all reported NASA innovations are software,” said Dan Lockney, NASA’s Technology Transfer program executive. “We’re pleased to transfer these tools to other sectors and excited at the prospect of seeing them implemented in new and creative ways.” The searchable catalogue is here: https://software.nasa.gov Wouldn't it be cool to use NASA code in your next project? https://www.youtube.com/watch?v=JIpyc8AfMZY

Xbox 360 Red Ring of Death - Fix Your Console Today and Enjoy Gaming Again Without Fear of Freezing

Since the Xbox 360's introduction in November, 2005, a significant quantity of Microsoft's game consoles have experienced a field malfunction that is indicated by three flashing red lights on the front of the console. It's The Xbox 360' Red Ring Of Death or E74 error.The "Red Ring of Death" is a very common problem. In July 2008, Microsoft admitted that over 800,000 people are dealing with it and 30% of all consoles sold are failing and the rest have a chance of failure. With an Xbox which suffer from the red ring of death, you will not be able to play games with peace of mind or any enjoyment and you can't use Xbox live membership without constantly dropping from online games, and losing level progress.Owning a broken $400 game system is annoying. If you don't fix the red ring of death, your system will only get worse with time, and your Xbox may stop working altogether (which will cost you in the hundreds of dollars to fix).The sooner you fix red ring of death the better, but first you should know what is wrong with your Xbox 360?The main cause of the 3 flashing red lights is overheating. In fact, it is an electrical connection failure between the CPU,GPU and the motherboard.due to an engineering flaw in the construction of the Xbox 360. When Microsoft designed it, they downsized the heat sinks ( which keep the system cool ) to accommodate the DVD drive, and they chose a slightly unusual way of mounting to link them to the processors. So when you play on your Xbox for too long, the temperature reaches beyond 120 degree, the motherboard heats up and begins to vibrate and flex against the X-Clamp plastic support . These vibrations loosen the soldering holding the graphics processing unit in place. This causes an electrical failure and the Xbox red ring of death error will happen.** How do we fix this ? **There is a myth going around that to fix the red ring of death errors by wrapping your Xbox 360 in a towel, turning it on for 20 minutes or so, and letting it overheat . BE CAREFUL !!! If you use this bogus repair method, you will risk turning a temporary problem into a permanent damage. This crazy method works for a few hours because when you wrap your console and turn it on, there is no ventilation for the heat to escape. It's like putting vegetable oil in your cars gas tank, sure it may run for a block but you have just ruined you car for a 2 minute trip! Your Xbox 360 is a piece of high tech equipment not a toaster, avoid completely the "towel fix" and any "fix" involving heat.** Is there a secure permanent fix for this ? **Of course, believe it or not fixing the Xbox red ring of death is not a difficult process and you don't need advanced technical skills or special tools to perform the "fix" yourself, I suggest you see a professional Xbox 360 repair guide with detailed clear video instuctions and pictures.

USB PC Fan Controller

As this is my first post I feel I should say how incredibly impressed I am with everyone here, you guys are inspirations! That said, I have a burning question, so powerful that I find myself emerging from the shadows to inquire of you fine folks if what I am about to suggest may be done. I want a Fan Controller for my PC project I am working on. I want it to plug into a USB port, and allow me to simply control Fan Speed (either through PWM, or simply raising and lowering voltages), but I want said control to be through a program I run on the desktop itself, not by some dial or automated temperature sensor system. Also it is worth noting that existing software solutions are inadequate, as my motherboard cannot support the number of fans my case will need. I have been looking at Arduino and it seems that this could be a viable candidate, allowing me to tell it through the USB to either speed the fan up, or slow it down at my whim. However being new to this I am not sure if one could actually accomplish said task. It would need to control at least 2 fans, preferably more, and possibly allow fans to be grouped. For a better idea of what I intend... I am building a rather monstrous PC, the case will be themed and modded heavily, and potentially include a 7" LCD screen on the side. This screen will be hooked directly into the PC, thus anything I want it to display should be possible. My intent is to have it display a combination of system stats, and allow for things like control of fan speed etc... I have looked into every possible Fan Control device commercially available, and not a single one, no matter how expensive, currently in production will suit my needs either technically or aesthetically. I feel a small internal control device that will allow me to simply click a button with my mouse would be far more efficient and better fit the intended design parameters of my project. So far I have spent three months on the planning stage alone, and do not intend to begin the first phase of construction for at least another month, while I iron out the few remaining design issues I have. Any help or information you guys can provide would be fantastic! D

I want to make an object which can register button presses and sent the time being pressed to a webplatform

I am a master student in Belgium doing Communication and Multimedia Design (Interaction)For my master thesis I am trying to find a method of supporting children whose parents go through a divorce. I am trying to do this by making a physical object (cube for now) and combining it with a digital (web)interface.The main goal is to have the physical compact and portable object (a cube with buttons for now) being used by the kid and he/she being able to press a button related to a situation or emotion they may encounter (read: portable diary). So wherever he/she is, they can use the object to express what they encounter (a button related to self image, a button related to denial, ...). This input then goes to a digital platform where parents and/or a psychiatrist can look at when and what the child went through and use that info to know which problems they are and start a conversation about it in a way that the child does not have to be upfront about it.I got most of my theory figured out and went to psychologists myself to see what these processes are, the next step is to now start making a prototype. This is where I have my difficulties and hope to find some help in this great creative community. I have a bit of experience with Arduino and have access to a lab with lasercutters, 3D printing, ...So the main technical questions are as follows:Which material can I use to make a compact enduring cube?What can I use to register button presses?How can I make this object so it can be turned on and off (so buttons don't accidentaly get pressed)?What kind of buttons can I use/make?How can I integrate a indicator light for it being on or off?How can I send the data collected?How can I collect and organise the data on the digital (web)platform?And how can I make this all compact so it fits in a cube of about 6 by 6 cm?I know I may be asking a lot and I don't expect you to answer everything or do it all for me, of course I will keep doing whatever I can while this post is here. But any input/feedback is welcome here, since I just started doing this first prototype, many options and suggestions can still be implemented so if you have any knowledge of what I try to make (for example sending data over long distances OR other suggestions on what object is could be) FEEL FREE TO LET ME KNOW :DThank you in advance! I hope to hear anything at all :D

Howtoons the Book Launches!

It's been a long journey since I first looked over Saul's shoulder in our shared 4th-floor MIT Media Lab office and saw the proto-sketches that would become Howtoons, but today the book finally launches! Here's the word directly from Saul:I along with my co-authors and illustrators, Nick Dragotta and Joost Bonsen are proud to announce that today is the official publication and release of our fully-illustrated, science-meets-adventure-and-mischief comic book, HOWTOONS ! The Possibilities are Endless. I know I personally am nervous, relieved, and all of the other things that a first time author can be. You can buy the book directly from AmazonAlthough all of the authors wish to compel you to walk, run, or ride a bike to your local book store and get one there (or demand that they carry copies!).We'd like to thank each and everyone on this email list for their moral and other support in the gestation of this exciting project. Thanks for loaning us your children, your ideas, your inspiration and your feedback. Hopefully we are now returning all of them to you in good healthy order and with interest on top!We'd love to encourage you all to buy hundreds and thousands of copies of this book for all of your favourite 4-94 year olds. The jacket copy says 8-12, but we know that our group of friends have nothing but the most intelligent children (hence extending the age range down to 4) as well as being fundamentally immature and appreciative of fart jokes (hence increasing it to 94).HOWTOONS seeks to put the joy, the story, the adventure, the free-spirit, the fun, the downright ridiculousness, and the real heroicism of science and engineering back into education. We do this through stories and illustrations designed to show children that science and engineering is not only one of the coolest possible things that you can study, but that it touches upon everything in modern life and can be found in the simple objects around you... One tag line we often like to associate with the book is: "See the world for what it can be, not for what it is." The world is increasingly technical, and many of the greatest challenges of the 21st century will require technically aware people whether they are working on science and engineering themselves, or whether they are the artists, writers, accountants, musicians, lawyers, politicians and educators who make the world a rich and interesting place to live. I believe the magnificent artwork of Nick also highlights that there is a genuine marriage between the arts and sciences and the oft cited tension between the two is un-necessary as both come from a desire to create and share new ideas and ways of representing them.You can see our new website, including many samples of HOWTOONS and a regularly updated blog at www.howtoons.com. We'd like to send an especially big thanks and shout out to Ryan McKinley for help with the website (if you don't know him you should! He's a programming powerhouse), and of course also to Phil Torrone, everyone's favourite blogger and DIY mastermind. We'd also love to thank all of the people at O'Reilly media, especially Dale Dougherty, Tim O'Reilly, Mark Frauenfelder and Carla Sinclair for including HOWTOONS in their fabulous magazines MAKE and CRAFT (www.makezine.com, www.craftzine.com). Also in the thank-you list should be Judith Regan who plucked us from obscurity to help us get started down the book-making path, and now the wonderful people of Harper Collins Children's Books for all of their help. We should include all of our apologies for editorial lateness!. Naturally we'd like to thank the people at Squid Labs and Eric and Christy of www.instructables.com fame for their support and work in bringing the make-it-yourself ethos to a much larger audience. MIT, MIT's media lab, and MITERS (MIT Electronic Research Society) are also to be whole-heartedly thanked for turning a blind eye to our insanity. The support of all these people and more (you) has been invaluable to us.Not to rest on our laurels — we are already working on a 2nd HOWTOONS book full of more wonderful projects and crazy storylines to encourage you to grab a 9-year-old and relive the joy of messing with world around you just because it's interesting, because rockets are cool, because bugs are fascinating, because flying is magnificent, because mechanisms are intriguing, because a sheet of paper isn't a sheet of paper, it's a work of origami art waiting to (un)fold.Furthermore, we are working on another book project, specifically a selection of DIY projects around the topic of renewable energy presented HOWTOONS-style, in order to encourage energy literacy and intuition amongst the next generation of engineers and scientists. Energy will be one of the key issues of this century and helping people understand all of the options and the promise and beauty of renewable energies is something we believe we can do to help.If you'd like to help support Howtoons in any way we'd love to hear from you; it is still a fledgling project in its infancy trying to wend its way towards fiscal sustainability. The biggest thing most of you can probably do to help is SPREAD THE WORD! Buy some books! Go out and give yourself the experience of reliving the joy of discovering the world by working on some Howtoons projects with your favourite kids (or even better, kids you don't know yet). If you have suggestions for future projects we'd love to hear about them. One of my favourite projects in HOWTOONS Book 1 is an open-source whooppee cushion that delighted my father (and haunted his teachers) when he was a 9-year-old and will hopefully induce raucous laughter everywhere.Again, thank you all.Saul Griffith, Nick Dragotta, Joost Bonsen,co-creators of HOWTOONS!www.howtoons.comPS. Finally, and most importantly I want to wholeheartedly thank my co-authors for their friendships, musings, and hard-work. It's tremendous to work with such great people at the top of their respective games.In case you don't know them (or me):Nick Dragotta first knew the power of comic art when he drew pictures of injuries on the blackboard at school that were so graphic that his fellow classmates had to leave the room to throw up. Since then he has tirelessly practiced the art of comics and researched the great artists of the field. Nick has drawn for Marvel and DC, including Spider-Man, X-men, Fantastic Four, and X-static titles. He is currently passionate about making more comic books for kids. Nick lives in a small apartment with walls lined by the shortened stubs of ruined pencils. He sleeps in a pile of eraser filings, drinks black ink, and exists on a diet of pureed superhero comic books.Joost Bonsen immigrated as a young boy to the United States from the Netherlands with his parents and his personal suitcase full of LEGOs. He grew up in Silicon Valley, California, immersed in that creative and entrepreneurial culture. While Joost was growing up, the vacant lot across the street from home served variously as play space, special effects set, race track, rocket launch pad and more as he and his friends made home movies, practiced being space explorers, and plotted space projects. Joost went to MIT for undergraduate studies in bio–electrical engineering and recently finished his graduate degree at the MIT Sloan School of Management looking at how labs are run, how research themes emerge, and how new technologies are commercialized.Saul Griffith grew up in Australia and his earliest memories of inventing things were of making grappling hooks for climbing trees and buildings. His childhood adventures included making his own rocket–powered toy cars, kites, and enormous puppets. He kept a diary of drawings of his inventions as a kid that included fantastic monorails and airplanes shaped like manta–rays. Saul ended up studying materials science—the structure of the materials we use every day—before going on to MIT to do a PhD in building self–replicating machines and a theory for folding 3–dimensional objects. He now works at Squid Labs in California inventing cool new things for making the world a better place. He still builds kites, they are just much, much bigger now.

How to use & wire relays, speed controllers, timers, micro switches, etc. with a DC motor.?

I would like to use a 110 volt, 1/2 hp (more or less), DC ( or AC ) reversing motor to move and close a horizontal, heavy (approx. 200 lbs.) fabric, thermal, curtain blanket and then to move and open back the blanket in a greenhouse. There are very expensive commercial greenhouse systems that exist to perform this task. Since I have a hobby greenhouse that is 30 ft. wide by 80 ft. long by 13 ft. tall, I need a much more affordable system. Horizontal wires or very large monofilament fishing line  (spaced 12" to 18" apart)  will run the length of the greenhouse at approximately the 8 ft. height. These wires or lines will be used to support the blanket and for it to slide on (the blanket will have grommets or similar devices used on a shower curtain to  keep the blanket running straight, etc. ) when mechanically closed and reopened. My idea is to use a DC or AC motor to perform this task with modifications to work in the greenhouse. The motor will consist of the 110 volt, 1/2 hp (more or less), DC or AC reversing motor, that will be connected to a small cable drum spool on the motor shaft, The motor  can be attached at one end wall of the greenhouse at 8 ft. high below or above the blanket and at the other end of the greenhouse also will have a cable drum spool with a pipe for rotation an be appropriately attached to the end wall. Attached to these 2 cable drum spools would be say 175 ft. ( 2 x 80 ft. plus initial amount on spool) of say 3/8 inch aircraft cable. The curtain blanket will have a say a 30 ft. long 1/2 inch or so horizontal metal bar or pipe attached to it on the leading edge. The aircraft cable will be attached to the blanket bar or pipe.The other end of the curtain blanket will be attached to the non motor end wall. As the motor turns the 2 cable drum spools  by wrapping and unwrapping the aircraft cable, the attached curtain blanket will be pulled the 80 ft. length of the greenhouse in each direction. What I want to accomplish is as follows:                                                                                                                                                        . 1. Be able to slowly, if possible, (say over 20 - 30 minutes) close (move forward) the blanket with the motor at a preset time in the evening and for the motor to stop when the blanket is fully pulled to the motor end of the 80 ft. greenhouse. 2. Be able to slowly, if possible, (say over 20 - 30 minutes) reopen (move backward) the blanket with the motor  at a preset time in the morning and for the motor to stop when the blanket is fully pulled back to the non motor end of the 80 ft. greenhouse. To accomplish this, this reversing DC or AC motor will need to reverse direction to reopen the blanket.                                                                                      3. The shaft of a motor will probably be too short to clamp a cable drum spool to. How do I attach the spools?                                                                                         4. What is best to use a DC or AC motor? I tried extensively to research on the internet how to accomplish the above, but everything described similar processes in vague and technical terms of using various types of electromechanical timers, electromechanical relays, limit switches, microcontrollers, MOSFET circuits, transistors, arduinos, bridge rectifiers, etc. I have no  knowledge of all of these electronic devices and am totally confused. However, I am pretty good at say basic home electrical wiring. The closest thing on the internet to what I am trying to accomplish is an automatic chicken coop door, but not enough specifics for my project. I need some very, specific steps, specific products and where they can be purchased to be able to accomplished this. What type of motor, types of electronic devices, etc. Also, since it appears I will need a timer, a speed controller, relays or limit switches, etc. how in the world to  wire these to the motor in laymen terms. Thanks so much for anyone that can help me!!!

Printer disconnecting or USB port disappearing in Windows

First I thought to make an Instructable out of it but realised there are too many different printer models out there, so this time no images. What is this about you might wonder? Well, let me tell you my story first and you might see similarities to your problem. It all started with me getting a new PC as the old one got memory problems (RAM modules failed). After a few successful prints I noticed errors coming up in the log window. Mainly things like communication problems and that some data is sent again. Realised that on my new PC I did not check the speed settings for the COM ports, so I adjusted them to match the printer board and moved on without even bothering to check the logs. Then, half way through a bigger print, it all stopped and I could not even connect to the printer anymore. After a power cycle on the printer all was fine again but the error kept coming back every now and then. At this point I started to read up on the problem and the most common recommendation is to print over SD - too bad if your printer does not support it and too bad it does not address the issue at all! A few more technical answers pointed to the Logitech drivers, especially mouse, keyboard and 3D vision. As I was using the same outer hardware as before and also the same drivers (and same version numbers) I simply ruled this one out too, although it might be a vital clue for others. When starting to get frustrated and after opening a cold blonde I remembered that I had a similar issue a long time ago and that it was related to loose wires on the screw terminals for the power connection. Measured it all but according to my trusty multimeter all was fine. Now comes the fun part: I friend of mine with a HiFi fetisch was here when I testing the connection and he started laughing at my attempts. He explained that ALL his connections, no matter if power or audio signal are oversized! Here I started to wonder if he is up to something and looked up similar circuit board mounted power plugs. To my surprise they are all rated for anything between 1 and 5Amps. Even without a heated bed powered by the printer board I think everyone will agree that a max 5A connections is not enough. My frined then offered to check the plug and connector at his place - what a great thing to have friends :) He used a signal generator and small speaker with the plug as a connector between them. With an oscilloscope connected to both input and speaker you could see, while moving the plug, that the audio signal become somehow unclean - there where spikes and missing bits everywhere depending which way you wobble the plug. After taking the whole thing apart the destructive way we saw the cause: overheated contact areas with discolored surfaces. I replaced the plug now with a 250V/20A one from an old laser printer and had no USB or connection issues ever since. Ok, what's the thing with power and USB problems on a 3D printer? Almost all printer boards have the ground connections bridged to avoid interference on the USB signals. This mean, in case of a faulty power connection or one that is "dirty", the USB port on the computer can receive back EMF signal or even a voltage spike. In return a smart bios either disconnects the port or disables it until the problem is solved, in our case by restarting / reconnecting the printer. But even with no obvious signs of power problems you can get  a so called "dirty" connection. Dirty covers all from corrosion, worn springs for battery compartments, overheating or in the old days burnt relay contacts. For our printer it usually means that either the soldering connection on the board or a screw came loose, in rare cases like mine an undersized connector can burn out due to being unable to handle the currents. The bad thing is that you can not always spot these problems the easy way... Is there an easy way to tell that my USB problem is caused by a faulty power connection? Yes and no. Some boards offer indicating LED's, you connect power and the LED stays on even if the printer is disconnected from the PC. If it is more than just a Power on" indicator" this LED will be off after the printer stops working and in the device manager your serial port for the printer is gone. You might also hear the warning sound from Windows in regards to a device being disconnected. If all the above is true than most likely your power connection has a problem somewhere - if in doubt replace all screw and plug connectors for the power. Sometimes the problem is less obvious. Your print software might show communication problems in the log window or re-send a lot of commands. If the speed selection for the com port is the same as for the firmware of the printer board and as set in the printer software, it could also be a power connection problem. But to be on the save side try a shielded cable with ferrite cores on both ends first for the connection between computer and printer. Can I take any measures to prevent the problem? Sure, you could solder everything and make sure the wires are fixed in place so they won't move. But a simple indicator might be enough: Solder a piece of LED strip to the power connection on the circuit board - if the connection has trouble the LED's will show it in most cases by changing light levels or flickering. On top they act as a nice light to see what's happening during a print.

How to get data from a load sensor through bluetooth module on an Android App/Arduino?

I am creating a mobile android application which gets data from a load sensor connected to HC-06 Bluetooth module and sends the data to a mobile application. The mobile app has two activities one for listing the bluetooth devices available and the other is the main activity to get data from the load sensor. I have managed to connect/pair with the Bluetooth module but I am unable to get data from it. The main activity consists of a button 'btnScan' that will get the data, and a text field to display the data.

Question by AyoS1    |  last reply


Tracking down the speed problems on a laptop.

I've copied the conversation here so we could remove the information from the original instructable's comments.  I figure this would also be of some interest to other forum viewers who may have similar problems, or may be able to chip in. The long and short of it is, 92033 (Ed) has a refurbished laptop that takes literal hours to run a YouTube video on.  I suspect that it's due to a bottleneck with his internet connection.  Here's the conversation thus far: ---------------------------------------------------------------- 92033 (Ed): Thank you kindly for your prompt reply...appreciate it very much. I came across this site by accident in searching for something else and now I'm 'hooked' on it. :) So far I've read over 400 archived posts (whew)...as well as looking at the videos. The videos are somewhat of a problem because this new laptop only has 512 mg memory...LOOOOOng time to load. For example...to watch a SLOW 5-minute You Tube video takes 5-1/2 HOURS to load...keeps showing a couple words at a time...need to get two new memory chips to upgrade to 2gb. Thanks again...Take care. ---------------------------------------------------------------- eddems: I think you're basic download speed is killing ya, not the laptop. check you're speed at Internetfrog.com, if you see the link near the bottom for the old test, run it, I like it's graph of upload and download speed much better. ---------------------------------------------------------------- 92033: Thanks much. I'll check it out. I ordered a 1gb SDRAM Memory chip which just arrived yesterday. Hope this speeds things up a bit. ---------------------------------------------------------------- harley_rly: i hear u man, my computer is hopped up, but i live out in the sticks and have dialup...i only get 24kbps at most :( ---------------------------------------------------------------- 92033: Maybe there's hope for 'us' yet. :-) I phoned Tiger Direct to see cost of an upgrading memory chip to go from 512mg to 1-1/2gb. The guy I talked to suggested I get "PC TUNEUP 2.0" which bypasses the Windows Operating System (I'm using Windows XP Pro) and speeds up the system. I gave it a try and ordered the CD (cost $39.98 - $44.77 postpaid). It hasn't arrived yet but will let you know if it helps as he claims it will. He said that if I just ordered a 1gb memory chip my system wouldn't notice much improvement as it is, but this CD should do the trick. THEN...when I DO order the Memory chip(s) to get total of 2gb my system should zip through like a rocket with the CD just ordered. I'll let you know when I get the CD and about the results. Just hope I haven't thrown forty-five bucks to the wind. Thanks for the contact...appreciate hearing from you. TAKE CARE. ~ ED ---------------------------------------------------------------- Javin007: PC Tune-Up "bypasses the Windows Operating System?" This guy fed you a load of crap. (I work on computers for a living.) PC Tune-Up does nothing more than clean up registries, defragment harddrives (if your OS even needs it, some don't) and keeps drivers up to date (which you could do manually.) That guy's an idiot, or just a liar. Could be both. Unless you were buying PC Tuneup 2.0 from Tiger Direct, in which case we can add "sleazy salesman" to that. What are the specs of the laptop? Go to Start/Run and type in DXDIAG. This will give you a quick snapshot of the specs. Specifically, I'm curious as to the processor speed/type. For a 5 1/2 hour "load" you're more likely looking at network slowdown issues (although 512 megs for XP is WAYYYY too little. I HATE when they put PCs together like that). The RAM upgrade will show significant speed increases, but no improvement with YouTube videos or other downloads. I'm glad to see you are returning the CD. ---------------------------------------------------------------- 92033: Thanks much for your input...appreciate it very much. I checked the DXDIAG as you recommended. Here's the info on it: IBM ThinPad Laptop PC. Model # 23738TU. Intel Premium M 1.70GHZ. 512mb SDRAM Memory chip.Page File- 351mb used,513 mb available. Direct Version-Directx 9.00 (4.09.0000.0904). 512 mb SDRAM-Actual 212 Ram. AVAST Anti-Virus. MS Windows XP-PRO.. Dialup Speed-40kbps. PC2700 SDRAM 512mb Memory Chip installed. I ordered 1bb memory chip which arrived yesterday. Now I have to figure out HOW to remove the bottom of this laptop to install it...lotta small screws on it. :-) Oh, total memory shows 32mb. I don't know if this means much to you. I note your comment that the added RAM memory WONT (?) speed up loading YouTube videos? Is that correct? If so, why not? Thanks again. Take care. ~ ED ---------------------------------------------------------------- Javin007: :) At the risk of boring too many people, here's how memory in a PC works: You have two kinds of memory: RAM, and Hard Drive (technically there's three, as there's also onboard video RAM on video cards, but this is primarily used for 3D video game textures, so can be mostly ignored.) Your harddrive's read/write speed is determined by the type of harddrive it is (most are SATA now) and the rotation speed (most are 7200 RPM, though the specs for your system say yours is only 5400 RPM, but there are 10, 15, and even 20K rpm models out there that are exponentially more expensive.) No matter what, harddrive memory will always be degrees slower than RAM. RAM on the other hand is a small chunk of memory that is "temporary" memory, but very fast. Its speed is determined by the type of RAM (DDR2 being the current common one for notebooks, though DDR3 is available with some motherboards (you can ignore this, though, as you can only handle 2 gigs max of DDR with your system). The motherboard will determine the limits for the RAM that can be installed.) When running *ANYTHING* on your computer, and I mean ANYTHING, it must first be loaded into RAM to be accessed by the CPU. The computer doesn't directly access the harddrive. So this means when your operating system is loaded (Windows XP) the entirety of all running processes for the OS have to be loaded into RAM. Now, Microsoft claims that Windows XP only requires a minimum of 64 megs of RAM, but recommends 128 megs. I challenge you to find me a Windows XP system that only uses 128 megs out of the box. It's not atypical for an XP system to chew through all 512 megs of your RAM, leaving no RAM available for other applications. (Interestingly, the default setup for your laptop is only 256 megs of RAM, yet yours is reporting 512.) What happens when there's no RAM left? The system has to then start trading things into what is called "Virtual Memory." VM is nothing more than a file on the harddrive that will temporarily hold information that SHOULD be in RAM, so the RAM can load more info. For instance, say you have a process that's using RAM, but you want to watch your YouTube video. As the video is ready to play, the system will take the other process's data that's in RAM, write it to the harddrive, load your video into RAM in its place, play a portion of it, write the video to the harddrive, load the data for the process to RAM, let it run for a split second (so it doesn't lock up), write it back to the harddrive, load your video into RAM and play a short clip, etc. etc. etc. The result of low RAM on your system is that applications will open slowly (seconds or minutes, instead of instantly or a few seconds) and they will seem slow to respond, will stutter, etc. With enough RAM, your system can freely open as much as it needs into RAM, and ignore the virtual memory and all the slowdowns that it causes. Now, all of this being said, NO lack of RAM will cause a streaming video to take 5 1/2 hours to play. This is 100% going to be related to your downspeed. (Go to www.speedtest.net and post your results.) RAM slowdowns tend to be most noticeable when shutting down, or starting up your computer, apps will open a little more slowly, they will be slower to respond to button clicks, and video will be very choppy. Anything that is causing a YouTube video to take HOURS will be due to the system simply waiting to get the video in the first place. RAM wouldn't slow down the receiving of the video, but it would cause the video to play weird once it's downloaded. So, all this being said, here's the summary: Your system has a 1.7 Ghz processor, and your RAM is most likely 333 Mhz DDR. If you bump your memory up to a gig, you should see a pretty significant improvement in that your computer will, overall, just "feel" faster. It'll be more responsive, and working with large documents will be many, many times faster. This won't, however, affect your YouTube experience (unless you were getting jittery video often, not the same as "buffering" video.) If you see "buffering" for a long time, your internet connection is your bottleneck. A test on www.SpeedTest.net will likely confirm this. However, if you get decent numbers on SpeedTest, then we could have something more sinister going on, though I suspect you'll find your numbers well below the 1 mbps rate. This brings us to actually changing the RAM. I've been out of the PC hardware realm (professional programmer now) for a few years, and was unable to find a manual for your particular model. However, if memory serves, this image should be a fairly accurate representation of the underside of your system: http://www.javin-inc.com/temp/thinkpad.JPG Don't quote me, but I BELIEVE the red circle will indicate the only screw you will need to remove to access the RAM. There should also be a small clip holding the RAM in place that you'll want to pinch to get the RAM out, and make sure that the new RAM snaps into place. (Sometimes you'll have additional empty RAM beds, and you can just put your RAM in there and end up with 1.5 gigs, but I suspect you'll have two 256 gig chips in there.) ---------------------------------------------------------------- 92033: Phew. Thanks again for your most indepth educational lesson. I appreciate all your help more than you realize. I attempted to answer this last night, typing in more than twice the amount of text as your to me, then suddenly realized there was a glitch and I was on another page...lost it all into the ionisphere. :-( Rather than try to retype all I wrote, I shut 'r down and went to sleep. Now I'm trying to recall all I wrote last night but failed to get mailed. I'm not a traditional typist, rather a one-finger bloke so you can understand the frustration there. I do, however, type at a reasonably good speed. With that said, let's continue. I went to search for Configuration of this IBM Laptop ThinkPad 23738TU and am copy and pasting it here.

I'll ATTEMP to try again later. So please don't reply yet as you need to read my discoveries in changing the RAM chip. Meanwhile, thanks again...take care. ~ ED ******************************************************************************* TRY #3...I'm Back :-) Your diagram showing where the RAM chip is located was right on. Thanks. Here's my DISCOVERY :-( The RAM chip installed was NOT a 512mg...but only a 256mg chip. The ads ans specs say it's a 512mg...NOT SO. I was lied to by either the manufacturer or refurbishing company who removed the original 512 chip and reinstalled a 256 chip. I was lied to by the Tiger Direct guy on the phone. There are NOT two chip slots...only one. So I now have a useless removed 256mb RAM chip. Replaced with the 1gb RAM chip I just installed. So instead of having 1-1/2 gb RAM, I only have 1gb. Here's the crux. To. go to 2gb RAM I'd need to buy a full 2gb RAM CHIP and discard the 1gb for which I just paid $39.99 ($45.00 with s/h). This means another output of almost a hundred dollars plus the $45.00 just wasted because they wont accept return once the sealed chip plastic was opened...even though I had no idea there was only ONE SLOT in this PC instead of TWO like the Tiger Guy said. Now...crux #2...this new 1gb RAM does nothing more to increase speed. I just watched a 2.01 MINUTE YouTube video which took a HALF HOUR to load, so I threw the money away for nothing, eh? There is no noticeable change except the 'speed' shows it now as 41.2 kbps instead of 40 kbps. Okay...now HOW do I get to speed this thing up to normal viewing in real time? I also saw an ad for 4bg RAM Gateway laptop with 120gb hard drive for $404.99 which is all suped-up with everything. I had to upgrade a LOT since I got this only four months ago...taking over a hundred hours to load it, like Internet Explorer 5 to 6 and then to 8 and now to 9. I'm using AVAST Anti-Virus, after trying for 23 hours to get ADVAR, then find out it didn't load because of problem on the servor's end. Added Firefox and upgraded twice. Loaded MS Protection but it created more problems so I deleted it...now with AVAST which I like. Soooo...I've literally spent over 200 hours to get this thng where it's at now, plus the wasted money for the upgraded RAM chip.and I still don't have increased speed. HOW do I get it? IF the processor has to be changed does this mean I have to gut the thing and install a new motherboard? If so, what kind of money cost are we talking here? I bought this four months ago as a refurbished unit only because I was able to get it on payments of only $25.00 a month. If I had to wait to get $400.00 cash I'd never have it. :-) Okay...that's it for the moment. Thanks much again for your help offering and detailed instructions...appreciate it more than you realize. Best Wishes And God's Blessings To You And Yours In Everything Always. Most Respectfully... ~ ED  ---------------------------------------------------------------- Javin007: Well, let's start with the RAM. If you're running windows XP, you can assume all the extra processes (virus scanners, and whatnot) will be eating up about 512 megs of the RAM. First thing to do is check DXDIAG again (start/run) and verify that it's now reporting the correct amount of RAM. (Don't be surprised if it's like 9 hundred something megs or slightly more. It won't report 1024 or 1 gig.) This being said, that will leave you with the other 512 for your applications. This box won't be running the latest and greatest 3D games, but I suspect it was never intended to. If the heaviest hitter you'll have running is along the lines of photoshop, the 1 gig of RAM you have now should be plenty sufficient. I wouldn't worry about getting 2 gigs. Not for this rig, anyway. Also, Avast is a great (and free) virus protection, every bit as good as Symantec's Norton, so good choice there. If your youtube videos are choking out, we need to start by verifying that it's an actual speed throttling problem. Go to www.SpeedTest.net and run the speed test. Come back with the results.
