I've got a Pi3 sitting around I was thinking about using to host the process while dumping the stream to a DB on my NAS. Assuming I'm not overflowing the ram is the CPU on this thing going to be a potential bottle neck versus just hosting it on AWS? The CPU is definitely a bottleneck when compared to even the smallest AWS instance, if you're not concerned about performance the rpi will work just fine though.

What kind of runtime can I expect out of a Zero W running on a usb battery pack? Thinking about making a timelapse camera. Obviously it'll depend on how often I'm taking pictures, if I'm uploading, etc, but anyone have any experience running any Pi like this?

According to this the Pi Zero W idles at 120ma, pulls 170ma watching 1080p video and 230mah shooting 1080p video. So if it's intermittent, assuming an average of something like 150ma, a 10000mah battery like this one would run for ~66 hours before needing a recharge.

Thermopyle posted:What kind of runtime can I expect out of a Zero W running on a usb battery pack? Thinking about making a timelapse camera. Here's a chart of the average current draw for various scenarios on the various Pis (all figures quoted with 5.19 volt input, presumably because it makes the numbers look a bit neater):  Each hour of your proposed workload should take up between 0.67 and 0.88 watthours of energy. At absolute minimum it would use 0.62 watthours per hour. So, using a standard 8000 milliamphour nominal capacity battery pack, like you can buy at any retail store for $25, you should probably be able to get around 36-40 hours of use? Even if the PI Zero W was running near full tilt processing the whole time, that should still get you around 24 hours of usage between charges when the battery pack is new and hasn't started losing capacity between charges. These numbers don't include what power the wifi chipset might use, so maybe knock off another couple hours from all figures to account for extra current demanded by the wireless chipset. That'd still leave you well over a day of use in most scenarios though.

I'm going to repurpose the Pi3 I've been using for Nvidia Game Stream to a simple OpenELEC/kodi box. I want to image the sd card to a file and rsync the IMG file to my server in case I ever decide to revert it back to a game streaming Pi again. It's got a 16GB microSD in it and I'd like to create the image ignoring unused space because I'm only using about 4GB of the 16GB card. Would something like this be OK: https://www.raspberrypi.org/forums/viewtopic.php?f=26&t=22524 Or is there a more widespread and elegant solution?

Do you mean you're only using a bit of the partition or that the partition is only a bit of the disk? If the partition is small just read from it directly (e.g. /dev/sda1 not /dev/sda.) If you mean only part of the partition is used you need to mount it and do a copy at the filesystem level as opposed to block level.

Are there any particular gotchas I should be aware of when deploying Pi-hole? I'm considering setting one up at my parent's place to minimize their exposure to ad/malware but before I do so I want to make sure I'm not just opening myself up to more hassle because it's a particularly finicky solution.

You need to whitelist a couple things for quality of life. I can't remember the exact domains right now but YouTube will stop recording history (which is useful for some people) if you don't unblock a domain there, and windows 10 won't update (even manually) without unlocking a few. There's also the thing that the top result on google is almost always a paid listing but those can be useful anyway, and when clicking those you get an error about the website being blocked which can be frustrating for someone that's not computer savvy. I really like the pihole on my home connection but my parents would be really confused if they clicked google search results and they came up with a website blocked error. Installing ad block plugins in their browsers might be a better idea.

If they're just using regular laptops or desktops, it'll be easier to simply install the same sort of hosts file blocking method directly to their computers. Also don't forget that power outages can corrupt the Pi's storage and make it unbootable, which will be a problem for them in a normal Pihole setup. You might want to prepare a second SD card and tell them how to replace it, so that they can get back up and running quickly after the original SD card gets corrupted.

A few weeks ago, I bought a RPi for a very simple use case: It should play / "render" music that is streamed from my Diskstation DS213j via UPnP or Airplay on a wi-fi connection. Currently, I have tried LibreElec, OpenElec, Volumio, RuneAudio and Raspbian with some installed packages. All of them seem to have issues with reliably playing the stream. Some just stop playing, some just enter a state where the music just stutters along, some regularly lose the WiFi connection. LibreElec worked the best. But sometimes the stuttering hits and I don't want to put up with that. Do the available distros just have a lovely UPnP implementation? UPnP itself doesn't seem to be that great of a protocol either. Or is the Diskstation lovely? I am having a hard time finding the cause of the issues here. Network congestion is not an issue, as is CPU load of the Diskstation. So, is there a kind of "best practice" to set up UPnP on a Raspberry PI? In case that doesn't work out, how would I go about using the RPi via Bluetooth (with an iPhone or iPad)? Out of the box, the distros seem to only use the reverse use case (RPi as source, some other device as sink).

I've had trouble with the uPnP on my diskstation in the past - I typically just run it as a samba share and map the network location to my rPI. No trouble with that setup. It's almost certainly a wildly antiquated practice, but I figure if it works then do it.

UPnP doesn't stream anything itself, did you mean DLNA, the standard for interoperability of media streaming that builds on top of UPNP? Searching for DLNA should get you better results. The only thing UPNP actually does on its own is configure external port communication for routers, and some minor identification of devices on the network to other devices on the network.

I think I will give this another shot! Currently it also skips but I guess that's because it's still busy indexing. It's a pity I cannot just use the DS Audio apps this way. fishmech posted:UPnP doesn't stream anything itself, did you mean DLNA, the standard for interoperability of media streaming that builds on top of UPNP?

Awesome, thanks! I've got a microcenter near me and for whatever reason have a micro-HDMI cable laying around, plus a bluetooth gamepad, so picking up a Pi Zero W and turning it into an emulation station seems like something I basically have to do.

If you want to do emulation I would STRONGLY recommend choosing a Pi 3 instead. The Zero is painful even to browse the web on. If you want to emulate anything better than maybe a SNES you're going to want the faster processor and more RAM.

I have tried off and on over the last 12 years (not joking, first device I got was in 2005) to make UPnP / DLNA music devices work and have completely given up. It's just a terrible protocol. There's a reason Sonos, Apple, etc. and other good systems rolled their own thing. IMHO it's not worth pain trying to keep making it work. Just use a bluetooth speaker for flexibility or get a chromecast audio. Neither are great but both are leaps and bounds ahead of DLNA.
