Would a Raspberry Pi be a good replacement for some of the apps I run on my Synology? Most are basically web\file processing stuff like Sonarr and a torrent client. The actual storage would be on my NAS which would be on a Gigabit LAN with it. I just want to offload the actual web stuff to something more stable since apps like to crash on my NAS for no reason and it adds an additional issue during troubleshooting to make sure it's a Synology issue vs just an actual program issue.

It wouldn't be doing actual torrent work. All I'd need it to do is the web UI display for that. The other stuff is all Python\Mono based. Edit: Honestly, the Mono\Python stuff is all that really matters. I'd even leave the Torrent web interface stuff on the NAS. Irritated Goat fucked around with this message at 19:53 on Jul 3, 2017 |

It only comes with a 10/100 ethernet connection which will top out at maybe 90 megabits per second in ideal conditions, worse when there's a lot of load on the other things that like it, are reliant on the USB 2.0 bus.

Yep, until there's a Pi with some real network hardware in it I have a hard time recommending it for anything other than low-demand network tasks (DNS, IOT, simple internal web service, logging, etc.). Even if you're saving it on a separate network share, torrenting would still involve transferring data through the Pi.

It's one of the biggest thing I'm hoping they'll change in the Pi 4: either eliminating the "almost everything goes through USB 2.0" restriction altogether, or at least changing that to run off USB 3.0 which gives a ton more leeway in what you can do for now. Everything going off the USB 3.0 bus would allow a true gigabit network port and rather decent disk access to occur without issues.

Some of the RPi competitors have gigabit Ethernet. The Asus Tinker Board and the Orange Pi Plus/PC2 models come to mind. They can be $50-60, but that's still way cheaper than a NUC. If you're comfortable enough with desktop Linux that you can set up a torrent server on Ubuntu, you can get an OS from Armbian and set up a server that you can remote into.

Are there any sites that aim to benchmark the various *-Pi devices, Beaglebone, et al? Would be neat to see how they stack up for various things, like storage I/O throughput, network bandwidth, compute, graphics, etc.

USB is intended as a peripheral bus, not as a system bus. This is something really deceptive about RPi performance, because it'll do I feel for the Pi Foundation and their compatibility issues but the Broadcom SOC sucked even 5 years ago when they did the first-gen, and it's locked them into some terrible architectural decisions and a terrible GPU (cue fishmech's rant, I don't remember the details but it's pretty horrific even compared to the SOCs on cheapo modern phones). It made the early Look for a little mini-PC using a low-power (5-15W) Intel mobile processor, there are more options than just a NUC out there. Zotac has the ZBox line (cheap), ECS used to have the Liva series (cheap), etc. I'd prefer these to the Orange Pi or other Pi clone boards for stability/software compatibility/expandability/etc, but if that's your pricerange then the clone boards do thrash the Pi in terms of features and total system performance. Some of them have SATA, gigabit, USB 3.0, etc. Shame the Athlon 5350 series is discontinued, you used to be able to walk out of Microcenter with a mobo and a CPU for $40 and put the whole thing together for $150 if you went for max cheap and $200 if you did it more decently.

I'm seeing a lot of 7" tft displays but they say raspberry pi 3, think they will work with a zero? I don't need the touch screen part I'd that's the driver that's built for the 2 and 3. Trying to source the last part of my cloud picture frame.

I don't need the touch screen part I'd that's the driver that's built for the 2 and 3. If they take regular HDMI in, they'll work fine with a Zero. If they're using the analog composite in, they'll require adding a composite port to the Zero. but they probably don't do that.

I think they publically said in an interview that they had no immediate plans for a Pi 3, then barely two weeks later announced the Pi 3 and in one of the interviews said that they'd been working on designing the Pi 3 for the last 18 months. Having no plans for a Pi 4 would be suicide for the brand; there will always be a demand for a bigger better Pi with low cost and low power requirements. Announcing that you're working on a new model would cripple sales as everyone waits for the next model to arrive, rather than buy what's already on shelves. Pi 3 already got 64 bit support, wifi and bluetooth; the big features I can see at this point are either an onboard camera, and/or sata-3 support and as discussed, decoupling the USB bus from the SD data storage. If they do that last item there's not a lot of incentive to stick with the same crippled (by today's standards) broadcom core that's mostly GPU and maybe pick something a bit more modern.

Pretty sure the broadcom chip supports booting from eMMC, the Beaglebone Black has had eMMC for almost as long as the Pi 1 has been around, if they wanted to do eMMC they would. eMMC is also an added cost, an SD card slot is a couple cents while an eMMC chip is probably close to a dollar which is going to cut in to their margins.

Hey all, I have a Pi 3 and I'm interested in mucking around with the GPIO -- Is there a HAT or some sort of kit that can expand the number of circuits it can control? Like somewhere in the neighborhood of 90 circuits?

Some more details about your idea would help give a better answer, but here goes: Serial-to-parallel shift registers are a thing that kind of multiplies GPIOs. They're cheap. Relatively easy. Another option is offloading to a microprocessor like an Arduino. If you want to get fancier, ESP8266 devices like the NodeMCU take concept wireless. eddiewalker fucked around with this message at 21:01 on Jul 7, 2017 |

eddiewalker posted:Some more details about your idea would help give a better answer, but here goes: Well, I've posted something of a work-in-progress thread in the project.log, but the gist is some old game show equipment that handles four buzzers, four voting panels of 5 buttons each, and five sets of chase lights (four circuits in each, in the backdrop and in each contestant lectern). The old computer that controls it is really heavy and adds a lot of setup time that I don't have. I'm having to build a new program to run it, as the current program is controlled by a light pen and not anything that can run on current systems. edit: I really love the idea of ScratchGPIO, because I've been able to build stuff with Stencyl before and I'm foolish enough to think it won't be that hard an adjustment to go from Stencyl to Scratch.

I'm trying to use a pi to receive bluetooth audio then forward it out over an internet radio stream. I thought this would be relatively simple but I'm having nightmares getting it to work as the bluetooth sink. I've followed this tutorial: https://thecodeninja.net/2016/06/bluetooth-audio-receiver-a2dp-sink-with-raspberry-pi/ on fresh installs of both xbian (as that's what the tutorial uses) and Raspbian, but to no avail. On xbian, I hit a dead end trying to scan for devices, nothing shows up and my pi's bd address shows as aa:aa:aa:aa:aa which I'm sure isn't right. On Raspbian I get to the end of the tutorial and my phone connects to the pi, but don't get any options to send audio. Does anyone have any ideas or pointers?

You can get an hp or dell Core i3 for like 299 or less on sale.. by the time you buy pi and mmc and the enclosure you're probably still that price point. Unless you want to do it "for science!" In which case source your own poo poo and 3d print a case from somewhere. Short answer no they are all big and expensive. tater_salad fucked around with this message at 23:14 on Jul 17, 2017 |

Sure, the construction is as good as always but not being able to replace batteries, ram, or SSD is bullshit. I'm still using my 2008 unibody Macbook but since I bought it I upgraded the ram, removed the combo drive and replaced it with a 1 TB HDD, replaced the original boot drive with a 256 GB SSD, replaced that with a 500 GB SSD, and I've replaced the battery three times. I'd like to see a new MacBook try to last 9 years.

If you're going to break your back carrying a goddamn Thinkpad you either need to go get an ancient monochrome gas plasma display runs-off-ten-D-cells luggable for the sake of humility or buy a walmart special craptop and live with it. All the modern T and W series ThinkPads are "good laptops". They're just outside of your apparent McDonald's part time price range.

At this point you can pick up a X230 for about what it's going to cost to put together a rpi laptop. It's about as tinker toy as laptops get, replaceable battery, the works. We have a dedicated laptop thread if you want to really get in to the minutiae.
