Want to make small heated wire with Raspberry Pi?

OK, so here is the details. I am playing around with thermochromic pigment that changes colors at 92F I want to use a very thin wire to heat parts of it for a few seconds at a time. I have a Pi 3 and a portable battery that can supply 2.4A and 2A at 5V. I would love to power straight over the GPIO (max of 16mA per GPIO or (50 or 60mA across multiple) on the Pi but powering it from the battery (or another battery pack) and controlling with the Pi would be fine too.

Raspberry Pi 24/7 Panda Cam

So I'm trying to make a birthday present for my girlfriend and something for her new apartment. She loves pandas and loves to watch the 24 hour live panda cams at the Smithsonian National Zoo. So I came across the idea of using a raspberry pi and a digital photo frame monitor to give a live feed of the pandas 24/7. Only problem is, I didn't realize Rasbian doesn't support Adobe Flash and there's no way to view the feed. Does anyone know if ARM Linux would support the feed. Or have another completely different take on a way to tackle this project? I want it pretty seamless so all see has to do it plug in the power supply and maybe an Ethernet cable and the rest be taken care of with a python script or something similar. I program for a living as well have a degree in Electrical Engineering so even if its complicated let me have it. I appreciate your help. Thanks!

At a stand still in my Raspberry Pi project. Help?

So I have been posting a couple questions concerning the raspberry pi and things related to it lately and I have trying to keep it vague because I'm attempting to build something with the pi and I don't know if it has been done before (it probably has and I just haven't found it).  Anyway, I want to make a rear view camera in my car, like newer model cars come with.  But i Have run into a few problems and i need the great people of this website to help me be able to figure these things out.  The problems: 1. I want to hook up the pi to the power supply in the cigarette lighter in my car, so that when the car turns on, the pi also turns on and boots up.  However, I want the pi to boot up and automatically open the camera preview function (with the Pi Camera Module) upon booting up. I do not know how to do this. 2. The display connection.  I want the display for the camera to be mounted to the dashboard somewhere, but the Pi, with the attached camera module, would need to be in the trunk somewhere, looking out to the rear of the car to actually function as a rear view camera.  So, I would like to connect the display to the Pi wirelessly and I'm not sure if that's possible.  I've seen a few boards and shield that you can mount on the Pi to enable wireless connectivity, but I'm not sure if that would work for a display. My display was originally going to be a screen i salvaged from an old laptop, to keep the price down low, however i have no way to connect the screen to the pi.  So now i figured I'd just put out the money and buy a touchscreen display. So please people help me figure out how to solve these problems, and keep in mind I'm fairly new to the Pi and programming. Thanks in advance!

Is this possible with the Raspberry Pi?

So I have recently purchased a Raspberry Pi and I finally go the time to mess around with it a little bit.  So far i have only installed the NOOBS software and have downloaded the recommended Raspian operating system, and have been using it as a desktop computer.  That is all I have done so far.  So I have an idea of something i want to create with the Pi.  I also have the camera module for the Pi and I'd like to put it to use.  I would like to have the Pi, with the camera module attached and operating, in one location, with a monitor of some sort, possibly a cell phone or just a display i would purchase, and have the camera wirelessly send the video feed to the monitor.  I'm assuming this is possible because i have seen instructables on here where people use the Pi to make security cameras. My idea is similar, just none of the ibles i found quite hit the idea on the head.  So, i guess i'm looking for someone to tell me if this is possible, and point me in the direction of how to go about doing this, or if there are any ibles on here that are exactly this that I have missed. Thanks

RPi2: OSMC Terminal Issue

I am trying to make some changes to OSMC through the terminal, but there is an issue with the login portion of it. When I quit OSMC, and wait for the boot screen, I hit Esc, and it goes into the terminal. Next, the login. I enter "osmc", then its to the password. But, it refuses to let me type anything in when I get to this stage. If I hit enter, it tells me that my password is wrong and then it goes back to prompting me to login. After about 15 seconds, it just continues to boot into OSMC. Why on earth will it not let me enter a password, and how do I fix it?

How do I stream H264 from Raspberry Pi to Paspberry Pi?

Doing a college project in which we need to stream live footage from on Pi to another over a network. We are using two Pi B+'s and the Pi Cam. We have no issues connecting the Pis, it's only the streaming that we have difficulties with. There is nothing that we've found yet that works and we have tried a lot. It would also be helpful if we input to a terminal at the same time but that all being hidden because we need to control servo motors too which are already working. All inputs and displays need to be on one Pi and the other Pi is connected to the Pi Cam and servo motors. We have heard that a common video from for the Pi Cam is H264 it doesn't have to be that if better options are available.

Calculating Pi using simple JavaScript

One day I was bored and wanted to calculate Pi for myself. After finding out the Leibniz formula for Pi. When it is solved for Pi one gets: Pi=4/1-4/3+4/5-4/7... And so on since it's an infinite series. Since one can see a pattern that can easily be defined I concluded that a simple program using a loop could be made. I decided on using JavaScript for its ease of use and use a for loop. The program I made at first was mainly: var Pi=0; var n=1; for (i=0;i<=1000;i++) { Pi=Pi+(4/n) n=n+2 Pi=Pi-(4/n) n=n+2 } Where the variable "Pi" is the value of Pi, "i" is the number of times the loop is repeated, and "n" is just a variable to help in the formula. This I however found could further simplified to: var Pi=0; var n=1; for (i=0;i<=1000;i++) { Pi=Pi+(4/n)-(4/(n+2)) n=n+4 } Of course the more times the loop is repeated, the more accurate your value of Pi gets, and while 1000 may seem like a large number, the value of Pi which it calculated is wrong after the 3rd decimal point. I've had it repeat over 100,000 times and it gets more accurate, however, remember that making the number of repeats can slow down and even crash your browser (I speak from experience). If you want some ready made scripting, then here's some scripting I've made which lets you easily control the amount of loop repeats. It is based as an HTML document: //Made by Masterdude var c=0; function Calculate() { var c=prompt("Enter number of cycles:","0"); if (c>0) { var Pi=0; var n=1; for (i=0;i<=c;i++) { Pi=Pi+(4/n)-(4/(n+2)) n=n+4 } alert(Pi); } else { alert("Canceled or Error in input: Input must be positive."); } }
