Fuzz1111 posted:Ordered one late wednesday night (there were 650 in stock), and it came midday today (friday). Yeah, really cheap powered hubs tend to provide power to the input. After finding USB devices inside the case of my regular tower had power while the machine was off, I decided to stop using cheap ones. I've already lost one motherboard to flaky USB controller issues (not a pi, just a computer).

I got a Raspberry Pi for Xmas with intention to use it as a set top box. I've been using an Nvidia Personal Cinema box for TV output for a long time (it came with a geforce 2 card so a very long time) and keeping a whole PC fired up just for tv output seemed silly with the current cost of power. So, I grabbed a spare phone charger and cable that outputs 1 amp. I grabbed some old lego and made a case (it's ugly since my 20+ year old lego is all different colors, but I have a molded case ordered). I put OpenElec on an old 2gb SD card and popped it in, hooked up a spare keyboard, plugged it into the TV and it's working great so far. I've only thrown lower definition videos at it so far because I don't have a HDTV, but they're all really clear and except when first loading a streaming video, it's very responsive. The only thing that kind of sucks is the text display on my CRT television is pretty annoying to read, but so far, all of the video I'm playing back is perfect. My current setup is accessing media over a samba share and controlling the raspi with Yatse on my android phone. I'll probably decommission my old media box soon and just move all of the file streaming over to my NAS. My favorite thing about it all is that the raspberry pi uses so little power and gets so much done, and I won't even need a special controller for it. Now I just need some more for more projects. If I want to display HD quality video in the future, I gather that there's a few things that are suggested in the thread so far, but I'd like some confirmation from folks currently doing this. I've read that using analog audio and not HDMI audio can cause the PC to have to do more processing and slow things down. I've also read that some folks overclock the raspberry pi. If you overclock, do you need to add a little heatsink to the cpu? Mine's currently running at about 131F according to the system info in OpenElec and this doesn't seem too hot for a full tilt CPU, but I figure it could get quite a bit hotter if it gets overclocked.

frumpsnake posted:It's not an analog vs HDMI thing, more of whether or not you have a setup that can decode DTS audio without the Raspberry Pi having to do it. Both involve HDMI. Thanks for the advice, it may be a while before I get a better TV but I was curious about some of the things I had read. This clears them up!

blackflare posted:My raspberry pi just shipped last week, and it looks like it's arriving within a few more days GPIO pins are general purpose input/output pins intended to interface with whatever electronics stuff you might hook up to them. They're often used to interface with sensors, LEDs, microcontrollers and the like. A good starting resource for the Raspi is the Raspberry Pi Educational Manual. It has sections for learning Scratch, Python, GPIO stuff and Linux command line things. It looks like they're going to add sections for Greenfoot and GeoGebra in the future, neither of which I know about.  http://www.raspberrypi.org/archives/2965

Basically 80% of this thread I can't make any kind of sense out of and I wish to remedy that. What can I use the GPIO for? Are there any interesting educational materials based around the rpi yet?

Jago posted:What kind of performance does a rasp pi have as a file server? I just did a bad test by copying a bunch of tiny files off my xbmc pi and it was going just over a megabyte. Not really fast enough. Does it work better using a USB disk and NFS(and not running xbmc)? It doesn't have particularly fast ethernet or USB controllers so I wouldn't expect a whole lot. Its size and cost makes it a decent fileserver if you need something portable but for home use I'd still go with the Packrats unite! The consumer NAS/storage megathread suggestions.

Dead Inside Darwin posted:I'm going to be getting a (hopefully) used RPI to use as a file server for some ZFS disks (doable according to http://raspberry-python.blogspot.com/2012/10/zfs-file-system-on-raspberry-pi.html). One disk is ZFS, another isn't, I want to pull the stuff off the ZFS disk to format it into something other OSes can read, but for now, I need the support. If you're hooking the drives up to the raspi, you will probably be doing so with USB to sata adapters of some kind (either external cases or something else) since it has no connectors for storage beyond USB and SD cards. If they're 3.5" drives they probably want an external power source, if they're 2.5" they may be powered by two USB connectors. A single cord solution for the 2.5" drives and the raspi will be a good powered USB hub. For the full sized drives you're going to need some external power supplies. If you absolutely need a single cord, you might be able to jury rig an ATX power supply to run sata power for the drives and also one of those in-case USB hubs to power the raspberry pi. It's a clunky solution, though, you would spend less on a power strip.

TVarmy posted:I'm finding I am really into web stuff more with the pi than the hdmi/gpio things. Are there any sub $100 low power, low noise computers that can run a LAMP stack with preferably a real sata port for a proper hard drive? Some of the embedded x86 development boards include sata and the like, but they tend to be a bit more expensive than what you're looking for. You might want to consider a mini-itx form factor motherboard with a built-in CPU to run as a server. It won't break any speed records but they often run without a heatsink fan (or with a small one) and are basically a standard x86 or x86-64 pc. The only issue is that while they're low power, they usually still take standard pc power and will need a (small) case and power supply. I bought an epia 933mhz board that was used on ebay for around $50 which included a 512MB stick of ram. I got a $40 case with psu for it and it's been serving as my router with m0n0wall loaded on a compact flash card. It's actually overkill for that use but it gets hundreds of days of uptime and I don't have to reset it like most boxed routers. For new models here are some examples: http://www.amazon.com/Gigabyte-Inte...ywords=mini+itx http://www.amazon.com/Asus-Celeron-Mini-ITX-Motherboard-C8HM70-I/dp/B00APL76WO/ref=sr_1_64?ie=UTF8&qid=1372627251&sr=8-64&keywords=mini+itx http://www.amazon.com/Intel-D2500CC...ywords=mini+itx

keyvin posted:I bought a UPS for my pi. External cell phone battery extender. Works great. Using a kill-o-watt I have calculated that replacing my PC that acted as a shell server with a Pi has saved me enough now to break even on the purchase of a Pi. Which means in another couple of months I can justify buying another one to do god knows what with. Has anyone tried running zone minder and a single IP camera on the Pi? I want to put up a camera on the cheap to keep watch on my car. I haven't tried this myself, but I have been considering trying it out. Having a whole low cost PC as a camera adds a lot of functionality. There are a lot of posts out there with people's raspi serving USB webcams for surveillance. The most recent one I read used the raspberry pi camera board and the shell of a fake security camera: http://www.raspberrypi.org/archives/5071 The linked article has descriptions of how they configured the software to record at 2 frames per second when triggered by motion.

I've bought from Newark Element 14 and resellers on Amazon (sold with amazon prime etc). The one from Element 14 died within two weeks somehow and I was able to send it back for a full refund (they sent me a shipping label). The one from Amazon got crushed in shipping and was also covered by them (with a shipping label) and they sent me another. The main difference for me was that Amazon shipped more quickly but didn't package it as well.

For a broad and not deep intro there's also the Raspberry Pi Education Manual: http://store.raspberrypi.com/projects/casmanual It goes over Scratch (more oriented at teaching programming concepts to kids but it's neat), Python, some stuff with the GPIO pins and some Linux. It's not a bad intro but I'd skip stuff you're not interested in.

I've heard of people connecting Does anyone know of a simple, reliable solution? Perhaps connect a bare joystick module to an analog-digital converter?

This hasn't been officially announced but hackaday reposted this article about someone being shipped a Raspberry Pi B+ which is a new revision (the original is: http://www.zlham.geek.nz/modules.php?name=News&file=article&sid=272 but it's being hammered): http://hackaday.com/2014/07/13/introducing-the-raspberry-pi-b/ Commenters have posted the datasheet: http://docs-europe.electrocomponents.com/webdocs/12de/0900766b812decd9.pdf  The main differences seem to be a switching power supply, 40 pin connector (27 as GPIO), 4x USB 2.0 connectors and just a generally better layout. Notable lack of a composite video RCA jack has speculation about the audio output being a 4 pole port with composite video being added to it, but there's no confirmation yet. Unfortunately the CPU is still 700mhz single core, but at least the layout is much better.

midnightclimax posted:I just got my RP2 B, and think I ordered the wrong case and heat sinks. Basically the space cut out for the CPU heat sink is a bit off, and there's no slot for the RAM heatsink (that I didn't get, just got two big ones). So for now I've assembled it, and put the heatsink on the CPU. It's not really covering it completely. Is this a problem if its primary purpose is media server/streaming stuff? Generally speaking they don't need heatsinks unless you overclock them or they're in an enclosed case in a hot environment. I did have a Raspberry Pi B overheat when it was sitting on top of a warm network switch in a case without much ventilation but I'm not sure a heatsink would have really helped in that situation anyway.

G-Prime posted:You make a very good point. Ideally, though, I'd like to not have to wire stuff in directly. My thought was to utilize the number of lighter sockets in the vehicle to convert to USB, have the UPS setup connected to that, and the Pi to there. The sockets shut off entirely when the ignition is shut off, so that'd disengage power to the UPS, which could then initiate a shutdown. I remember reading about a few of these UPS hats for Pis, but haven't used one myself: https://www.modmypi.com/raspberry-pi/breakout-boards/pi-modules/ups-pico https://www.pi-supply.com/product/pi-ups-uninterrupted-power-supply-raspberry-pi/

What's the best way to power it from the Pi's own pins, or failing that a good thing to use to power it externally - preferably from USB? Most of the fans meant for raspberry pis I've seen are just 12v fans you run off of the 5v pins and they just run slower. I think pins 4 and 6 are the most commonly used for that:  I was considering buying this case before and the images include one showing the fan on those pins so it seems right: https://www.amazon.com/dp/B012GPCLR6/ If you'd rather use USB you can butcher a cable or whatever:

The SDIO I'm familiar with is literally an input-output device in an SD card form factor, popular in the early-mid 2000s for PDAs and ultracompact computers. They usually look something like this, since they need to fit in an SD card slot but also need space for the extra antenna or whatever: I don't know why they did it this way, but there's no misunderstanding. It shows up in the device manager as Broadcom 802.11abgn Wireless SDIO Adapter. It is an M.2 connector it plugs into but apparently it's a SDIO device. Maybe they use the physical M.2 connector for internal board installs of SDIO devices. I'm not sure what interface it's connected to internally. edit: apparently it's connected to SDIO internally, as is the onboard eMMC according to this review of it, at least http://www.techspot.com/review/907-ecs-liva-mini-pc/page2.html

The Pi 3 gets pretty warm so it's good to have heatsinks but those little ones only do so much as it is. If you have heat problems (which you likely won't unless you overclock it or something) then you'll want to add a fan anyway.

forkbucket posted:One of those e-ink displays would be super cool in a nice slim case together with the pi for displaying weather info and time/date. Are there package deals for weather station thingamajigs for GPIO? Or would a weather station be more of a completely from scratch project? This isn't a Pi project, it's got its own ESP8266 microcontroller, but I picked up one of these kits for a weather station recently. It's in the mail and I need to 3d print an enclosure, but it looks pretty neat. Since it's just a microcontroller with a screen it can technically be used for anything, but the basic setup includes the weatherstation as an example. https://mcuoneclipse.com/2017/10/22/squix-esp8266-based-e-paper-weather-station/
