Statistical Process Control

Is there any interest in Statistical Process Control? I posted one instructable about it: https://www.instructables.com/id/Using-Statistical-Process-Control-to-test-the-Atti/ I am considering an instructable to measure the quality of resistors. Do they really hold 5% tolerance? The test is simpler than the test in my last instructable, and I would get deeper into the maths.

Dual HDMI Processing

I have an idea for a project that needs to process 2 hdmi inputs in real time, and 1 hdmi output. What kind of processing power would I need for this? I don't think an arduino would be able to handle it, but would a raspberry pi? Or should I be looking at like a mobile dual-core or something? I'm trying to keep it in a small form factor and have it the least amount of lag possible. Thanks, -Nikon

multiple processes in arduino? Answered

Is there an easy way to run multiple voids at the same time on an arduino uno? preferrably without aditional libraries, but I cannot flash AVR code to it (must be through IDE).  I do NEED to run the processes at the same time, no they do not share pins or variables, and the timing does not need to be precise.  I am trying to run two steppers at the same time, but different speeds, but the big catch is that I don't have "smart" drivers, just a 2003 and 293, so they each require a separate void to move, and they cannot be run simultaneously without running both voids at the same time.  Basically, I'm NOT looking for an alternative, just a way to run two voids at the same time (or switching back and forth very quickly without being affected by "delay();".

Prize Claim Process

I am a little confused about the prize claim process.  I got a PM with a link, went to the link and filled out the form and clicked "accept."  But it was kind of weird that I didn't get any acknowledgement that I submitted the form.  Also, for an Instructables prize pack prize (which includes a shirt) shouldn't they ask for a shirt size?  When/where/how do they do that?  I guess I am just worried that maybe I am missing something. Or that the form isn't being submitted properly. Or maybe I'm just being impatient.

macePod - The procession project

Hi Art+Tech lovers Is it possible to track a simple object and calculate it's distance with an Arduino + (Arduino-)camera. I would use a simple tele lens so the distance between the camera and the object can range between 0.5 and 10 meters. The camera can be mounted on 2 servo motors for pan-tilt movement. Everything sits on top of a 2m pole, carried by a person.  And best wishes for 2016! Philippe

Arduino + Processing + Servo control

Hello there! Im new to processing and i need some help. I have written some code that works but badly.  SImply all its meant to do is take the my keyboard input ( with proccessing) and based off that turn a servo left or right. How ever i encounter a weird problem. For the servo to turn i have to press each key on the keyboard twice.... and also when i hit 'w' there is a big delay of about 2 seconds for no reason... The processing code: import processing.serial.*; Serial myPort; void setup() {   myPort = new Serial(this, Serial.list()[4], 9600);   println(Serial.list()); } void draw() { } void keyPressed() {   switch (key) {   case 'w':     myPort.write('1');     break;   case 'p':     myPort.write('2');     break;   default:     myPort.write('0');   } } The arduino code: #include Servo myServo; int ledPin = 13; void setup(){   Serial.begin(9600);   pinMode(ledPin, OUTPUT);   myServo.attach(9);   myServo.write(0); } void loop(){   int val;     val = Serial.read() - '0';   while (Serial.available() == 0);   if (val == 1){     for (int i ; i < 180; i ++){       myServo.write(i);           }   }   if (val == 2){     for (int i ; i < 180; i--){       myServo.write(i);     }   } }

Is it feasable for an eighth grader to build a small (4 computer) cluster running linux?

I am going into eighth grade and for my science project i want to build a computer cluster running linux. for my project  i want to test if the time it takes to process something would be cut in half, thirds and fourths when doubling , tripling and quadrupling the number of computers, or slightly less than half, thirds and fourths because of various factors slowing down processing speeds the more computers are added. Is that extremely impractical or is it possible? if so would i use software types such as pvm or mpi? Finally, are there any suggestions as to what program i should process. i need something that will stay constant ( if i did two tests with the same computer the processing time would generally stay the same) but also take long enough that slight time differences would be noticeable (1 computer takes 2 hours, 2 computers take 1 hour and 1 minute, 3 computers would take 41.5 minutes and so on and so forth).

Export integer from arduino to processing?

How can I take an integer or float value from an arduino, and put it into processing over serial (usb), without changing it to a char or something else?  It needs to be fairly fast (within ~1/8 sec), and be able to be converted to an audio tone.  Also, how can I play an audio tone in processing?  I looked on the reference page, and couldn't find any documentation on just a basic square or sine wave output of variable frequency (except the example, which uses something weird).

Comment Submit Process can be Better

Often times when I'm writing comments in a slow or interrupted internet connection, I notice that the comment is uploaded in such a way that the comment box is removed as its contents are being sent to the server, and once upload is done, the comment section resets with the new comment in place. If the comment isn't sent to the server completely, though, or if connection with the server is lost, the comment box disappears, and the webpage continuously tries to, unsuccessfully, upload the comment to the server. This often leads me to having to re-write the comment, sometimes being a very long and annoying process. So, lovely Instructables Developers, I'd think it would be very nice if you could add a few lines of code to your PHP so that the box is only un-editable while the comment is being set, and so that if upload takes longer than normal, the box is editable again and a notification appears.

process for anodizing aluminum with limited equipment?

Recently I have learned the basics of anodizing aluminum, and from what I understand the basic process is to clean of the aluminum bit to be anodized, stick it in a bath of a dilute solution of sulfuric acid, and do some electrolysis with the anodizing bit connected to the anode or positive of a supply, then pulling it out some time later and cleaning it off with soapy water and rinsing, and coloring the metal in a thin runny die, then wiping off excess and boiling the part. So first of all, do I need sulfuric acid? Any substitutes? Will HCL work, or a weak acid like vinegar or even salty water?  If the purpose of the sulfuric acid is to allow free ions to flow in the water, I do not see why it would not work. However, I am not a chemist, and my experimentation with electrolysis is limited to 6th grade science and dropping 9V batteries in salty water. (My favorite experiment was at home when using copper  and coins as the electrodes and watching blue-green corrosion develop and sink until the copper wire was made brittle and thin. Caused some AA rechargeable batteries to explode in the process though lol!) Also, will any die work? For really small parts, will it be possible to evenly die them with sharpie, standard paper markers, and/or highlighters? What dies will work well? Should the dies be water based, or based on some other thinner?

Lessons Learned/Process Documentation Feature

I have found that, in many new projects, there is a certain amount of planning and a whole lot more trial and error (as expected). As such, the second time I make a project may be drastically different based on the lessons learned from the first. When I think about how I want to present the Instructable, there is always a struggle to capture all the failed attempts without cluttering up the "go do this and it will most likely work" version. Perhaps it depends on the project. Sometimes, I want to just see the steps that work. Sometimes, it would be nice to hear every detail on what didn't work along the way and why the creator decided to do certain things and how their creative process flowed. An idea would be to have some sort of collapsible section of each step that contains all the lessons learned. For example, if you're sewing button holes for the first time in your life, you will probably want to practice a few times. You could capture all the "unused" attempts in the "lessons learned" section of the "Sewing Button Holes" step without cluttering up the satisfactory attempt that you end up going with. This may not be such a useful feature for smaller, simpler Ibles, but could greatly enhance more complex Ibles that involve fairly experimental processes. Maybe you've never used a miter saw before, so you research it a bunch and read all the Ibles on it and look through the forums. You could link all your research within the Lessons Learned and take everyone through your experiences and trials without bogging down your Ible step with too many photos and thoughts. On a larger level than cleaning up Ibles, this could possible enhance the learning opportunity in every Ible, bringing emphasis to processes instead of end products. Maybe you could even tag the Lessons Learned sections and make them searchable as their own entities. Maybe you just want to create an entire Ible on each process you used and link it in the step. This could go in many directions... Thoughts? Ideas? Post links to Ibles that might be able to benefit from something like this?

Raspberry pi 2 processing capability?

Hearing the announcement of the new latest and greatest Raspberry Pi 2, now a backwards compatible computer with a 0.9GHz ARM Cortex-A7 quad core processor and 1GB of LPDDR2 SDRAM, I was wondering of the feasibility of using it as a very cheap and basic solution for a simple computer for my lab. Currently, I am using a compaq presario C700 Pentium Dual-Core laptop, that has been maxed out with 2GB 800MHz kingston RAM, and is running Kubuntu. I should also not the HDD has been replaced with a 120GB one from an old and broken Xbox. I do not like it much anymore, because although the performance of it is acceptable, the screen is a bit low res, at 1280x800, it's pretty dark (or at least until it 'warms up' to full brightness), it had a major scratch on the screen, (no idea how it got there) and after buffing it out with many methods, including with an eraser, the area has became discolored, like a portion of the screen has higher gamut and brightness, and lower black levels. :( Oh well. The main killer for it is that it's form factor. It is too big, heavy, the screen is too small, and it is very cumbersome to use far away in the corner of my workbench. Of course being a laptop, the 'base' of it is fixed to the screen, and to move it closer to me takes away lots of valuable space on my really messy bench. I mostly use it to research part numbers, get schematics off of google, watch YT videos, log data from serial ports (including my UNI-T multimeter with basic data-logging capabilities), and stuff like that. I may have as many as 20 tabs open at a time, which did tax my old compaq C700 when it had 1GB of RAM, but that was likely due to a memory leak issue with chrome, since I have the SAME issue with my main desktop, with 8GB of DDR3 RAM. If the video by MAKE is anything to judge, it looks just as powerful, as this embedded video is large! https://www.youtube.com/watch?v=pZz8MW3DSqA My hope is to replace it with a raspberry pi, and be able to use it for these basic operations w/ a old LCD monitor which can be picked up off of craigslist for cheap. Maybe I can even find one in the dump :P. Maybe I can configure the GPIO pins to be COM and parallel ports, w/ clock, Tx, Rx, and everything else!

cheap & easy way to do optical mark recognition (omr) or crude image scanning / processing?

What's a cheap & easy but reliable way to scan a crude drawing or do omr - optical mark recognition - ie read marks on paper like the forms you fill out with a #2 pencil ? I envision something like a row of 8 lights sensors spaced to match the lines on a 3x5 index card, you feed the card into guides aligning the lines with the sensors. Or get some graph paper & scissors and cut out some 3x5 cards. Perhaps this could be a crude scanner to scan simple drawngs at whatever resolution matches the spacing of the sensors (width of drawing would be limited to # of sensors, the length limited to arduino's memory/storage). You could hand-feed a 3x5 card with a drawing through it, the horizontal resolution would be the spacing of the sensors, maybe have some kind of roller to track the card being fed through so it knows to scan another line. I know there are sensors used by line-following robots, but what about a simple light sensor? Or buying a cheap camera element and hooking that up to a video input and processing the image inside arduino? Or processing input from composite video? Any thoughts?

My question therefore, is how would one go about getting the Tom Tom to run programs that are written in Java. Thanks in advance.

is there a way to end a process that you are denied access to?

 I vowed to my engineering teacher that I would, eventually, figure out how to get around the program he uses to control and lock our computers. he knows I wouldn't use it for bad things (ie using my computer while he's talking) but I just want to try to do it. does anybody know how to end a process, even after it says "access is denied"?
