pi coders wanted

Looking for a few coders to help make a better 3d system based on the pi and arduino. apps available will incclude: 3d printing tool usage CNC 3d scanning and more to come I have next to NO experience in coding but have designed and tested 2 machines that I need programmers for. these will be opensource at the end and also sellable. I am hoping to make a store similiar to playstore or app store so that advanced programmers can also make a small amount for exceptional products. the idea is huge but could be beneficial to several thousand people including users of this forum in helping them with techniques and skills they have not yet mastered. the project is HUGE and the mechanical side is largely done with the exception of a few parts that are added extra. other inclusions will be safety features and high perfomance. for those that are interested in this AND have coding experience I look forward to your replies on this topic

Some php trouble with Dreamweaver

I'm giving my sister a hand with her pharmacy website for the university she goes to. And we got a link on the main page: Pharmacy main page . The link is for the phrosh (frosh with a p due to it being "pharmacy" har har, I know). If you look on the phrosh page itself: Phrosh information . The thing is that it's supposed to have the same grey tile as the main page, and on my sister's computer (she sent me a screenshot) she's got the background on there, but you can't actually see it online.. Any ideas guys? Thanks.

Coding Showdown - Programmers and Hackers, beware.

 Hi all. I have created a password protected page, and I want YOU to break it. It's simple. It's in JavaScript. And it's waiting. Just: Go to (edit: page no longer exists. too late!), and - by any means - acquire my password. Ehhem. The winner might get something. Edit: I changed the password, due to a mistake on my part where it actually told you the password.

Help with Arduino Coding

Hello. I have recently been interested in coding Arduino and the USAF lets me to launchpads to setup remote cameras that are sound activated for a rocket launch. I was working on designing an Arduino connected to one of the cheap sound detector modules on eBay. The camera would be triggered by a short circuit on the digital end, with the sound module on the analog end. The camera is activated by a short circuit on the shutter release, so I though I would have + going into the camera when sound is activated with the other cables on ground. I just needed someone to check over my coding, as I am debating whether or not to buy an Arduino. No errors appeared on the computer, so I don't know if it will work fine or not                                                                                                                                                                                                                void setup() {}   //Just there as placeholder: void loop()    //To repeat a function of detecting sound: {const int SoundDetectorPin = A2;  //Sound Detector Module located at Analog pin 2:   const int CameraTriggerOutput = 3;  //Dual Trigger Output is located at Digital pin 3: //Following is If functions: if (analogRead(SoundDetectorPin) == LOW) //When power is read, if it is LOW, the trigger detected sound:      digitalWrite(CameraTriggerOutput, HIGH); //Pin 3 is given positive voltage: else {  //If opposite happens:     digitalWrite(CameraTriggerOutput, LOW); //When power is read, if it is HIGH, the trigger is detected nothing and no command is excecuted:    } }

Beginning Robotics-- Where Should I Start?

Hello, as you can tell from my profile, I have a passion for robots.  I'd like to have a career in developing artificial intelligence in particular, and I would like to start sharpening my skills now.  Unfortunately, I'm not sure where to start. I was wondering if someone could give me an idea where to start out, as well as if someone could provide a link to a C compiler (preferably free).  Thank you very much for any help.

How to connect a physical pushbutton to a display to trigger an animation.

I'm trying to figure out how I would set up a physical pushbutton so as to trigger an animation once pushed.  The programming language I'm using is processing, and the content would be played on a 32" screen.  So I'm trying to figure out what type of hardware I would need (circuit boards, pushbuttons..etc) in order for this to work.  Thank you in advance to anyone that offers some advice.  P.S. I also have little knowledge in programming this is a project so I can become more familiar with it. Thanks!!

Anyone interested in making a Video Game?

Hi. I'm looking for a group of people to help me make a Video Game. I have lots of ideas, but the big problem: I have absolutely NO coding, drawing, or music composing skills. I'm looking for people who have those skills, and would like to help out. I live in Canada, but you don't have to live there. I'm good with Skype, or something else. I'm fine with any software. I don't have any money, but I was going to put the games on Kickstarter, and I could pay people off that profit. I have ideas about most genres, like RPG, or action, or even a simulation. One idea is this war game where you command a small army, and attack other people. I can't really explain much, other than you can upgrade your troops, and unlock special troops, like Motherships. Or maybe a tycoon game. I don't really know, I mostly come up with ideas on the spot... So that's all I think i should say. If you need more questions answered about me, just ask. PLEASE HELP A GUY OUT!

stewart platform with firgelli linear actuator using arduino codeing help!

I am building a stewart platform as part of a larger assembly to accuratly position an object in all six degrees (transition in x,y,z) and rotation about each of these (pitch, yaw, roll). I plan to use an arduino board and 6 firgelli linear actuators. Any help on how to go about programming this would be a great help, or if anyone knows of any open source code so that I do not have to do the reverse kinematics as Im not strong enough in math to do so. ive attached a pic screenshot of my design. thanks

I know this is a stupid request, but can someone please code for me the movements of the robot? I will attach a video on how I want it to move. I will only use motors sg90, jumpers, and arduino but I need the arduino code.So I want 4 things to move, you can see all of them in the video. I will then connect it to my computer and use my keyboard for movements. You are free to put any keys you want to control it. Please help asap. This project is for tomorrow for my school.

Code blocks not respecting code

So, I got some feedback that my 'ible has some errors in it (which is somewhat expected :D )  I went to the instructable, to do some editing and noticed that the problems are likely coming from and tags that are in the code blocks. I tried to remove them, but they come back when I save.  I noticed this happens in *all* my code blocks.  Changing the format of text in code blocks makes Instructables unacceptable as a way to share code. Considering the amount of code for many projects on this site, this potentially breaks many of them, or at the very least makes it harder for others to copy the code for their projects.   Please make tags repect all formatting within!  Thanks, JR

Where to look for mobile app making info

Hi everyone, I have a project I would like to make in conjunction with a mobile app. Basically I will be making a container with a number of compartments, I would like to be able to monitor these compartments and find out if (and when) they have been opened. I would like to build an app with a simple GUI, a grid of squares for example. When the compartment is open perhaps the corresponding square would change colour and a timestamp may be displayed... For example. What I would like to know is what people may suggest is a good way of getting started with this project, where to look and any advice would be greatly appreciated. I am keen to learn and research, at the moment I just feel a bit lost as to where I should begin.  I understand making apps for android is much more financially viable, someone once told me it is much more expensive through the Apple app store.  So please, and books, youtube videos, forums, websites you can recommend for a beginner in this field who is keen to learn. Best, Henri

Fm transmiter coding help

I need a little help determining a code that is used to run a Fm transmitter program through a Fm module and the AVR Butterfly. Here is the original article of the transmitter but there is no code that went with it and I tried to look for the file online, but I was unable to find it. There is this code that's on AVR Freaks, however, I do not know if that is the code for the transmitter (and I do not know what the code is suppose to look like because I barely know programming). I have all the parts ready to build it, I just need to know the code to make it run. Any help would be appreciated.
