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

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 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?

How can I build an electricity monitoring and control system?

The service will be to install energy monitoring equipment in a premises which records kW hours electricity usage and also voltage fluctuations. This data will be collected every few seconds, but summarized every few minutes. The recorded data will be transmitted to local data hubs and then over the internet to analysis software providing outputs which are meaningful to management. Several monitoring devices will be deployed in a building so that data can be collected in individual circuits or individual electrical machines. Additionally there is a requirement to control devices remotely so that they may be switched or moderated remotely. Thus for example, a heater might have a thermostat setting adjusted or be switched on or off.

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 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!

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! My hope is to replace it with a raspberry pi, and be able to use it for these basic operations w/ a old cheap LCD monitor which can be picked up off of craigslist for cheap. Generally old 4:3 monitors go for next to nothing. Maybe I can even find one in the dump :P. Maybe I can configure the GPIO pins to be COM ports, w/ clock and everything else! That way an external FTDI chip and using the limited number of USBs is not an issue. Is that possible?

Power a Raspberry Pi and an audio amp on the same circuit?

Hello. I want to use a 3A 12V power supply to power a Raspberry Pi Zero W and a 12v/50W audio amp. I think what I should do is a) split the power from the supply, b) connect the amp directly to the 12V and c) on the other leg, pass the source through a step-down buck converter. I have two questions:1. Is this feasible?2. I also want to pass the 12V through a relay that will be controlled by the Pi. Will this mean that all 3A will go to the Pi when the relay is open and the amp is off? Is that bad?Thanks!

Using Raspberry Pi (running Openelec) to turn off TV and Amp when idling.

Hi, I was hoping that you guys might be able to offer some advice to this problem (have looked everywhere and cannot find a possible solution). I have a Raspberry Pi 2 (running Openelec) connected to a TV via an A/V amp. Is there a way, whereby whenever the Pi hasn't been used in a while and goes into a lower power state, it can cut the power to the TV and amp?  The point being that I can then leave the Pi on all the time and simply press the remote to have the TV and amp come on automatically. I have considered power saving power strips but I am not sure that the master socket would work with a Pi because of the small change in wattage between idling mode and full power. The only possible solution I have found so far is somehow to use these: However, am I  correct in thinking that Energenie only works when you are using the Pi as a dedicated home automation solution? I would be so grateful for any help. Thanks
