blunt posted:Just in case anyone else was wondering about this, it turns out Plex won't do any transcoding on ARM chips Out of curiosity, does it entirely refuse to do it, or just fail at performance? Libav is there on Raspbian jessie, and ffmpeg there on stretch. As I've found out though, the CPU just doesn't have the grunt to use x264 at reasonable settings in anything approaching real time.

YouTuber posted:Anyone familiar with using a Pi for receiving FM signal? I noticed that Kodi has a "Radio" tab on their new UI and was wondering if I could rig up a setup that would allow me to listen to FM radio over my network. My initial searches is drumming up "Software Defined Radio" but I understood this to mean shortwave frequency stuff used by the greybeards. Does this hardware cross over into medium wave frequency now? I'd love to be able to just flip on the radio and listen to it without a huge delay like you get over the internet. We have a great local Football commentary crew in Philly that I'd prefer to listen to rather than get stuck with Joe Buck. You can receive FM radio with a pi, but you'll need an FM tuner which it doesn't have built in. I don't have a short answer for a simple FM tuner with drivers out of the box, but if you go down the "software defined radio" rabbit hole then one of these: https://www.amazon.com/RTL-SDR-DVB-T-Stick-RTL2832U-R820T/dp/B00C37AZXK and GNU radio will let you recieve almost anything under the sun.

underage at the vape shop posted:For a course this year, I have to make something with a raspberry pi 3. They haven't released guidelines yet but I have absolutely 0 ideas for anything that would be cool. It is a beginner class so I'm not sure how much they'll really expect but I'd still like to do something that I'd enjoy making. Any suggestions? Use a relay, lamp and a webcam to make a device that will flick a light on and off as rapidly as possible when it sees a person. You'll have to fiddle with the timing to see how quickly a modern CFL / LED bulb can be turned on and off without breaking.

fishmech posted:And if you want it on a TV, picking up a used Xbox One or PS4 can be a pretty cheap way to go. They both run full Minecraft versions, support full Netflix resolution, and the Xbox One now has a version of Minecraft that can play directly with people playing Minecraft on Windows 10, iOS and Android tablets/phones, and soon the Nintendo Switch. PS4's version will get that in afew months but there's still some issues to hash out there, it's the same capabilities though. What's a "Full minecraft version" nowadays anyway? I thought that the Java version was still the only one with private servers, and you can sure run original Minecraft on a hacked chromebook.

Eletriarnation posted:Having run a Raspberry Pi 2 for several months as an always-on torrent server in the past (using Deluge) my opinion is that it works well considering the inherent limitations of the platform, but those limitations are significant. Make sure you have a reliable power source that's actually putting out close to 5V so you don't get random brownouts and system disk corruption, and realize that all of your I/O is going through a single USB2.0 bus internally so there are serious limits to how fast it will go. Even with the reduced processor in the Zero it should be fine just to run a torrent server but there's no way you're going to be able to get files into or out of it at much more than 10MBps with locally attached disks. I used a Pi for that usage case for a while, and it was frustrating having a gigabit internal network and 250mbit internet, while the Pi couldn't even saturate fast ethernet. An atom nuc like this one is so vastly better at that same job, while still being a tiny quiet power efficient box.

Steakandchips posted:Question: What's the next step up from a raspberry pi that is more powerful and can use a 2.5" ssd? A NUC? Most NUCs are a bit of a big jump in price from a pi. You can get used ultra-small form factor desktops for really cheap, or you can be like me and ebay a used i5 NUC for $140. At the point where you want good SSD performance, you likely want a full blown x86 computer, of which plain old corporate desktops will be cheapest.

I would like to play with a completely toy solar + battery setup for a Pi with some sensors, but some quick math showed me that even a Pi Zero 2 sucks down a considerable amount of power at idle, so I'm going to have to complicate my setup some more with a small microcontroller that wakes up the Pi occasionally, then cuts power. Does anyone have a recommended solar + charger setup that they've validated works? I don't need small, so I'm really tempted to go with a cheap LiFePO4 or even NiMH battery back of some type, also because those are less likely to burn if I gently caress something up. To solve power usage, I'm thinking of throwing a Pi Pico in there too, having it spend almost all of its time in deep sleep mode, and then waking up according to a timer, letting the pi run long enough to do its thing, and then shutting it down again. Also, does anyone have a recommended LoRaWAN setup for a Pi? My vision here is a self-contained solar powered box with sensors that can use LoRaWAN to wirelessly send values over line of sight about 1km.

I'm throwing an old Pi 3 into service as a power monitor at a GFCI outlet in my crawlspace that nuisance trips so that I can get alerted immediately when it goes down. I figured I'd host a page, forward a high port, and use Uptime Robot to yell at me when the page is down. I intend this thing to serve a webpage and do nothing else. I don't want it to write at all if possible so that I can preserve the SD card. Based on https://raspberrypi.stackexchange.com/questions/109422/how-to-disable-logs, I've disabled rsyslog and configured journald to use only volatile storage. Is there anything else that I missed? What else should I do to make a Pi serve a static page for the next 10 years from my crawlspace?

Inept posted:Yeah but running a desktop instead of a Pi for the previous 4 years would have cost them at least an extra hundred bucks in electricity, and probably several hundred I've been using an Intel NUC that I got used on eBay for $140 for 8-ish years now, an i5-4250U idles at 6W, the whole thing is under 20W at full tilt, and even with a 9 year old processor it runs laps around the Pi 4. Pis idle at what, 3W? So I've used worst case like $100 more in power, but realistically it's a wash because it's idle most of the time. Edit: if you're trying to min/max this the pro move is a fanless setup that you also use as your router so that you can avoid paying the watts for a separate router. AT&Ts router is hot as hell and sucks tons of power but I can't do anything about it. Twerk from Home fucked around with this message at 02:30 on Jun 11, 2023 |

What's the simplest way to get a pi, a single 3.5" hard disk and a SATA adapter to connect the two of them into a single case with a single power supply? Or is this too much to ask? I realize the easiest option by far is an external USB disk and 2 wall warts, but I'm curious if anything exists. This would be for direct playing media off a giant drive, not a NAS. It's fine if the SATA is through a USB adapter internally, I'm not going to pretend that I need native SATA support, although it looks the Pi OS did pick up SATA support a few years ago: https://www.jeffgeerling.com/blog/2021/raspberry-pi-os-now-has-sata-support-built Edit: it doesn't even have to be a pi, x86 or ARM mini PCs that run a normal Linux are fine too but the Pi space seems most likely to have something. A single 3.5" bay, that's all! Twerk from Home fucked around with this message at 19:14 on Nov 11, 2023 |

mewse posted:Not sure a powered usb hub would cut it - the pi recommends 2.5 amps, will the hub support that power draw on every port? The way I would probably try to do it would be to buy a cheap 5V power supply then wire a bunch of usb breakout boards to it Wow, this becomes more appealing given that the power supply spec for the Pi 5 is 5V@5A, which very, very few general USB chargers will provide. I wonder how often the fan would kick in on that PSU. Is there a reason to do USB breakout rather than just powering the Pis off of the pins in the GPIO area?

Does anyone have a recommended application to test SD cards, or at the point where one is a few years old and has ever done anything iffy should I throw them away? This is for more than just Pis, for better or worse I've got a lot of SD cards in a lot of different devices. Also, is the official case the best way to cool a 5? How do they hold up with just a passive heatsink on there instead of a fan? Is there any way to throttle down target power instead? I want to use a 5 as a (toy) ARM CI server, comparing it to cross compiling + QEMU emulation on x86. If heat throttling just makes it slower without any wear or damage concerns, I'd be happy just to let it throttle.

There's a good reason why Qualcomm, Broadcom, Mediatek, or any of the other mobile chipset vendors have failed to make big inroads while Apple, Ampere and Annapurna have been able to sell into consumer and server markets.

I'm extremely skeptical of the raspberry pi IPO, what's the stated goal here? I need to look more into it, are they raising a bunch of capital with the plans to make many more products? Will more capital let them avoid the manufacturing problems they've had? Why public? It's going to make more work for them and if the core vision is to keep prices down for hobbyist computers, I just don't get how this helps.

Eletriarnation posted:Pi 5 performance is comparable to the Atom-level chips, far beyond what Pihole needs. You could set up a console emulation frontend like Retropie, a file server, a container sandbox, a VPN gateway, or lots of other things. I'd also argue that if you want to do those things too, you'd be better served by the Intel chip given that they cost the same amount as a Pi 5 anyway and come with an nvme SSD instead of SD cards or a USB SSD.

mewse posted:Geerling did a video recently where he tried to compare a pi 5 to a brand new mini pc. He was forced to concede performance per dollar is loving awful for the pi, but then charted "performance per power usage" to try and salvage anything the pi might still have going for it. Those no-brand mini PCs ship with insane BIOS settings and power limits far higher than those CPUs need to perform well. If you change a setting in the BIOS (or buy a real brand like Intel NUC) they blow away the RPi5 on performance per watt, which they should because they are several silicon processes more advanced.

Yeah, the GPIO out of the box on something massively more powerful than a microcontroller plus a gigantic community are what make the RPi neat and why I'm still posting in this thread. I do feel like they've been so hard to get for so long that they are putting the future of that community at risk. I guess the 5 is easier to get than a 4 over the last few years, but I'm curious how they price a 2GB / 1GB model.
