Raspberry Pi

Hello everyone I wanted some suggestions from the users of raspberry pi on where to start after getting the raspberry pi. I've searched the web and found a lot of things, but they weren't exactly beginners friendly. I am upgrading from an Arduino to a Raspberry pi and the difference between them is enormous. Arduino seemed a lot more welcoming and easier compared to Raspberry pi. So do you guys have some tips or places to start from for me? Any help is appreciated. Thank You

Raspberry Pi 3 Interactive Led Strip Wall

At the moment we're working on an interactive led screen wall for the entrance hall of our new studio. I've setup the following frame (http://i66.tinypic.com/33ll30j.jpg)  with 17meters of WS2812B addressable led strips.We're using the Neopixel library for rasp (https://github.com/jgarff/rpi_ws281x) and it works like a charm with the rasp 3. Anyway they next step is to control these ledstrips so they work as one big display. I had a look on the internet and a lot of people advices to work with the FadeCandy from Adafruits but I want to know if there are other solutions using only Python and write software to control the ledstrips. The purpose is to use the rasp's camera module like this guy did http://andydoro.com/ledmirror/images/stills/ledmirror01.jpg so when someone is entering the room, his reflection appears on the wall... Any information / tips / other solutions about how to achieve what I described above are welcome. Thanks

Raspberry Pi Composite?

I have built the Ben Heck portable Raspberry Pi.  I had it working, but then I bumped the case and after that, the video will not start up.  My wiring to the monitor is all still good, and I know that it is getting power.  The only thing is, that during the bump, the video data and ground cables may have shorted.  Could this have caused the problem?  Whether it did or not, can anybody please help me fix it?

Arduino or Raspberry Pi?

Well I am a 16 year old High School student interested in engineering and things of that sort. I recently took an engineering class at my school and was thoroughly pleased with the concepts. My father is also an engineer, and would like me to dive deeper into these sorts of things. Being a long time Instructables  user I came here to seek guidance. Most of the Instructables of recent times have used Arduino and/or Raspberry Pi. I would like to learn more about these tools and what they are used for. Which one do you think is better, easier to use, and/or faster to learn.

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

Raspberry PI power?

Hey yall! I just recently bought a Raspberry Pi! Those of you who want to order know how hard this is, so Im pretty excited because i didnt think Id b able to order for awhile. Anywho, I wnat to make or buy a portable power supply for it, but I am not sure how to go about doing that. I know there are tons of portable CHARGERS out there for iphones and what not, but I am afriad these will attempt to "charge" my PI, therfore frying the board. Do they just supply power and the device recognizes power being recieved, so it displays charging? And I will be attachin a BUNCH of things via a usb hub to the Pi, so I doubt regular bunch of 4 rechargeable AAs will pwer my device for long with all thse extrra things drawing power. So my question is 3fold: can I buy one of those portable chargers to power my Pi or will it fry it? will 4 AAs be enough to power the Pi and all the extra usb things? and will it be more cost efficient to make a power supply? (I definetely want it be rechargeable, though). Any links to products, or guides to make one would be extremely helpful. Thanks in advance!!! Also, I already have a wall supply, but I need a power supply that is portable.

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!

New here, and to Pi/Python looking to log data from a few different sensors from Atlas Scientific (RTD & PH).  I've gotten really stuck so fare in getting these going and was wondering if anyone here can help me out.  so far I've used this code:  import smbus import time import datetime #SMBus(0) - Raspberry Pi Model A #SMBus(1) - Raspberry Pi Model B bus = smbus.SMBus(1) #I2C address of sensor address = 0x66 def temperature():     rvalue0 = bus.read_word_data(address,0)     rvalue1 = (rvalue0 & 0xff00) >> 8     rvalue2 = rvalue0 & 0x00ff     rvalue = (((rvalue2 * 256) + rvalue1) >> 4 ) *.0625     #print rvalue1, rvalue2     return rvalue print("Temperature Data Logger\n") while True:         #Open Log File     f=open('tempdata.txt','a')     now = datetime.datetime.now()     timestamp = now.strftime("%Y/%m/%d %H:%M")     outvalue = temperature()     outstring = str(timestamp)+"  "+str(outvalue)+" C "+str(outvalue*1.8+32)+" F"+"\n"     print outstring     f.write(outstring)     f.close()     #log temperature every 10 seconds     time.sleep(10) I've got the two sensor boards connected to the raspberry pi 3 mounted via a Whitebox Tentacle T3.   The boards are in i2c mode and i can see them using sudo i2cdetect -y 1 (they show up address 63 and 66)  but when i run this program above I just get a red error light when it reads the temperature.   The log file reports a measurement of 2C and 35.2F which is not correct but the red light on the board tells me that the Pi is trying to connect with it.   Anyone able to help?

Computer science in schools - advice and arguments needed.

You may have heard that UK schools will be teaching Computer Science from September, instead of teaching ICT (= "how to use Microsoft products"). Most people will agree that this is a good thing, since the basics of Office can be grasped in an hour or so, and hardly need the current years of study. However, last year, whilst several thousand people qualified as ICT teachers, only 3 people qualified as Computer Science teachers.  Many existing ICT teachers only ended up as ICT teachers by chance.  That group includes me, but I am fairly sure that I will be asked to teach Computer Science next year. So, here's the thing:  I am not confident that those with a grasp on the purse-strings know enough to make an informed decision regarding the route to follow in September, investment-wise, and  I know I'm not. Possible routes that occur to me; The school teaches programming etc on PCs, using software to model the device being controlled by the programmes children write. The school invests in Arduino or Arduino clones, and forges closer links between the ICT and Technology departments to teach Computer Science through the medium of robotics. The school invests in Raspberry Pi, plus the required peripherals, and teaches programming of computers from the ground up. In all three cases, the existing ICT suits would remain as a resource for other departments to use. In 2 & 3, I would like to see the hardware being treated as a consumable, much like printer ink or wood. In all three cases, nobody currently employed has any skill in those areas and has no time to be formally trained in those areas, so would need to learn alongside the pupils. What do you think? Which of these routes should I encourage my school to go down?  Why? What other options are there?
