I just moved my pihole over to a container on my nas, was so easy to just save settings and reapply (although strangely the dhcp settings did not cone over). Now I need to think of what to do with this spare pi! One thing I was thinking about was get familiar with network booting so I don’t have to use sd cards, I think a netboot.xyz container perhaps.

Sometime in November the SD card in my Raspberry Pi 3B died, so I decided to bite the bullet this weekend and start moving all the strange things I was doing on it to the 4B I've had for a couple years now. One of the things I'd been doing was running an hourly speedtest with speeedtest-cli using Python, posting the results to a Google Spreadsheet, and displaying it on an epaper display. However, it seems that while I've got 100mpbs download/5Mbps upload on the line, and the Pi-3 was generally reporting pretty close to that when running, the Pi-4's speedtest-cli executions are always showing 2.28Mbps download/2.26 upload, when speedtest.net is generally reporting in the high 80s when run from the browser on the Pi 4. code:Edit: Looks like it may have been some sort of issue with the service speedtest-cli uses in my location, speeds are back up to where I expect them to be. Edit: Nope, now they're back down to 2Mbps again. maltesh fucked around with this message at 21:58 on Jan 13, 2022 |

I’m building out a RPI cluster and I am planning on 8 nodes of RPI 4. As I recall they are 5v 3a, so that should be 15w, 15x8=120w power supply. So far I found a 120w USB hub for crypto mining but they are quite expensive. I’m trying to have one power plug and multiple USB C cables to power them all. Any suggestions?

This is one of those questions that are laser focused on the wrong solution. PoE or rolling your own octopus with a big power supply brick are probably it, not USB.

There's a big difference in power requirement from the first gen Pi to the Pi 4, which is why using USB for power has gotten a lot more expensive. Hadlock's big 5V supply is going to be a good idea if you're using a lot in one location but you want to get a good brand since the Pi doesn't tolerate much voltage fluctuation. You'll just need to figure out appropriate wiring for 15 Watts DC and hook it to the expansion header: https://github.com/raspberrypi/hats/blob/master/designguide.md#back-powering-the-pi-via-the-gpio-header Since you'll want a well regulated 5V supply don't skimp and get the cheapest one. Meanwell makes decent power supplies and probably has an appropriate sized one for your project. A lot of the bigger ones have fans which do make a little bit of noise but it's not a crazy amount if you get a decent one. Some of the smaller ones are fanless and you could consider using multiple smaller ones if that noise is an issue (like say use a 10A one for two or three Pis). There's also laptop brick style power supplies that will usually go up to 15A or so, you'd just need a barrel jack and wire it out to the different units. Might be worth putting switches in line for each one if you're wiring up your own power to a cluster.

Ha, seems to be a common thing. I just realized that Jenkins doesn't do ARM32 which is supremely annoying. While I do love my little workstation pi using a m.2 case at that point I'd be better off using a NUC for about the same amount of money.

Ever since I got my nuc my pi's have only served for off grid projects.. like camera controls or disk cloning. Though the previously discussed power requirements with the latest models are putting that at risk. I guess they make low power models but I want the usb3.

I'm thinking of getting a Pi to serve as a pi-hole / Plex server, and eventually also occasional octopi duties whenever we finally dig out the printer again. One of the main reasons I want to do this is to finally offload Plex duties from my main PC so I'll be able to leave it unpowered most of the time. Does the Pi 4 B perform well enough to handle those duties concurrently? My main use case for Plex is streaming 1080p content via Chromecast to the TV and occasional usage from an iPad, and I'd like it to be able to handle 4K in the future. I tried using my NAS as the Plex server but it choked on streaming. It's mainly my wife and I that use the internet so we won't have a lot of concurrent open sessions, but I'm worried that internet access will suffer when streaming via Plex.

I bought the cheapest one that is nvme only. So one of the i3 ones, for anything you were considering a pi for it's still a ton of power. Mine is probably five years old now, it's run as an ssh gateway, pihole, netflow, and a valheim server without breaking a sweat. No k8s on it but it's running flatcar for all the container goodness.

I tried using my NAS as the Plex server but it choked on streaming. A Pi 4 still isn't great at transcoding on the fly. It can do some though -- the 4 has hardware for H264 1080p 30fps encoding. But that's it. One stream only. When using Plex server on a limited device like a Pi or NAS box, the thing to be highly aware of the limit on transcoding. This means your devices that are watching need to be capable of playing back the original file, and set to original only in their settings. I'd guess that was why your NAS box didn't work, because otherwise it's just serving the file. But if your playback devices are limited in what formats they can ingest, your plex server needs to do transcode. If you need a plex server that's able to do higher spec hardware encoding, you want to step up to something much better. An intel NUC box would be pretty ideal: still pretty power-efficient and quiet, and intel's GPU has pretty great hardware encode support. Not nearly as cheap as a pi though. Don't Ask posted:It's mainly my wife and I that use the internet so we won't have a lot of concurrent open sessions, but I'm worried that internet access will suffer when streaming via Plex. As in the pihole response getting slow while the plex server is in use? Don't think so. The Pihole part is super simple.

I use a pi4 for torrenting and plex and it does "fine". It plays 4k for a single user without issue. Every now and then there is a file that stutters even though the bitrate isn't that high but it happens so rarely I've never bothered to figure out why. Of course, seeking on those large files isn't fast but I guess I don't do that much. Having said that if you have the money and space a NUC is surely going to provida a more pleasant experience.

This may be worthwhile for folks to know - Plex does have a "pre-transcode" feature that can optimize stuff for a specific device - you need some extra disk space on the pi to keep it on there, but I think you can preset it so that the things you're streaming most have an easier time being direct piped to a device. My Pi4 was having issues with Plex, but it turned out to be a leading indicator of an SD card that was garbage. Now almost everything works fine - although I usually just do 1080p since my projector + roku stick are not 4k compatible.

The recommendation for 3A is to ensure every peripheral plugged into USB can draw full power, and because the onboard regulator sucks rear end and reports "low voltage" for no goddamn reason. It's a lot cheaper for the Pi Foundation to recommend overspec supplies than it is to fix the regulator.

What you said about encoding support is something to think on though, it's a 1st or 2nd gen Chromecast and I'm not sure that it even supports H.265 so that's also a problem. A NUC would do the job but I'm hoping that the cheaper (and less energy demanding) Pi will do the trick. other people posted:I use a pi4 for torrenting and plex and it does "fine".

Good point on the torrenting, that's another thing that I'd want to offload from my PC since it's all on the NAS anyway.

I've been running Plex on an RPi4 since the 4 was released. It's great for one transcode at a time, which is about all i have outbound bandwidth for anyhow. I also have it running Nextcloud (which is just barely usable, probably because PHP), transmission, an Atlas probe, and some custom software to rip and transcode optical media. It's also routing traffic for five VLANs to two upstream ISPs. The only reason I can get away with all this because everything is usually idle. I'm also concerned about power use, and this is a great solution. So I'm gonna go with yes, you can run Plex on it 😉
