Alpha Mayo posted:Would this make a good Gigabit router if I bought a USB3->Ethernet adapter? And not a wifi access point, just a plain router (and maybe VPN server/client if the CPU is good enough) There's a large difference between being able to transmit at gigabit speeds and routing at gigabit speeds. Without routing ASICs that you find on hardware routers, all the packets that the PI receives are going to be processed by the CPU. The processor is better than the previous PIs, but I seriously doubt it would get anywhere close to gigabit speeds. e. Whoh, didn't mean to dogpile you.

Could possibly use a USB SATA adapter and a cheap used SSD to solve the SD card problem. I mean you could also buy a used thinkstation or something at that price point, but it won't be PI sized.

Those fucks are gonna get ripped right off. I'd bolt the thing to a monitor and clamp those cables to something solid.

Yeah you can, but it's all command line. I've got an ER-X and was looking at running a VPN server on it, but when I started looking into setting it up I came across quite a few people having issues with it and it basically came down to the ER-X not having enough cpu to run openvpn well. So I run an openvpn server on my pi zero that is running pihole and that works fine for me. (That's for me connecting back to my home network when I'm at work or abroad)

Anyone try webcam streaming with a Pi? I’m doing a research project and needed a small device able to transmit a low latency webcam stream so I’ve picked up a Pi 3B+ and have been fiddling around with it. I’ve tested webrtc streaming with uv4l and the web browser function that has and I got a low latency gstreamer h264 stream (~1 second over Wifi) to run to my Windows 10 laptop running an Ubuntu virtual machine so I’ll likely be looking into a dedicated Ubuntu laptop to hopefully trim down that time further and cut out the occasional grey screen + visual artifacts that pop in. Is there a recommended format for low latency streams on a Pi? Has anyone run into that occasional grey screen issue? I’ve made a lot of progress but this is all really new ground for me, and any information anyone has on streaming would be great.

I had an old Seedbox on a pi 3 running well a while back. It had a 500gb drive attached and never missed a beat. Not too long ago I swapped the drive to a 1.5tb one and since then I noticed that popular downloads would always be slightly corrupted. I'd have to verify them a couple of times to grab it all. I also noticed the speed would bounce around from ~ 10mb down to 0mb and back up again when copying from the drive to my windows machine. There is nothing wrong with the drive, I'd been using it for other things prior and copying to / from it via the network (eg. I had it plugged into my router at one stage) and it was all fine. I've also tested it since, so I don't know if it's just not playing well with the pi or how I had set it up (eg. file system, samba, etc). I used the pi to partition and format the disk last time and had samba already setup to go. So anyway I decided to start a new image( as the old one was based on hassio anyway ) and wanted to know if there are any better ways to set it up? Should I just do the same as I did last time, or should I maybe format the drive as NTFS and install ntfs-3g on the pi this time? Any other ideas?

switching to the new rPi4 would be a very big upgrade for any network/disk heavy use case like yours because it finally gets rid of the internal USB bus.

TheKingofSprings posted:Anyone try webcam streaming with a Pi? Switch to MJPEG instead of H.264 video. MJPEG is just a dump of raw JPEG images so it takes more bandwidth but is super fast to encode vs. H.264 on the current Pi (although the new Pi 4 they mention the updated videocore can do H.264 encoding now.. but who knows what software support is like). I've tried both methods and MJPEG streams are nearly instant (way less than 1 second latency) whereas H.264 streams have at least a second or more of latency when you wave your hand in front of the camera. Check out the mjpeg-streamer tool if you need some quick software to expose the Pi camera video as an image you can embed in any webpage: https://github.com/jacksonliam/mjpg-streamer

wolrah posted:Glad you found the answer. Also if you drop a wpa_supplicant.conf in there it'll automatically install that and start up wireless on boot, in case you ever have a need for a wireless Pi that you don't want to have to plug in to a LAN first to set up (especially useful for Zero W). If I'm not mistaken, dropping a wpa_supplicant.conf will replace the old one as well, so you can potentially update the settings if the network has changed.

It seems to support gstreamer and some nVidia vdpau. I found some video players can do it and some can't. I ordered an intel whateverthefuck M.2 adapter for the nano yesterday because I'm sick of using the Vonets adapter for it since the USB dongle bit it. It's ungainly and messes with other nearby WiFi devices. I also ordered a couple more of the USB adapters because they are only a couple of $ each.

Does anyone make a case/box that holds a 3.5 inch HDD and a Pi(4)? Like for the seedbox example, I have an external USB3 drive and basically want to tape the Pi to the side of it. With a tiny bit of design surely you could have an all-in-one box with a single power supply etc.

I was working my pi4 pretty heavily this weekend, with it sat in the bottom piece of a pi3 case. I started getting a little thermometer appearing in the top right screen which I'm assuming was the overheating warning since the thing was roasting. I popped it out of it's case and sat it up on a couple of dice to improve airflow and it's been running fine since. Kinda reluctant to buy the pi4 official case, since it looks like it'll have that same problem unless I invest in some heatsinks and fans. Looks like my next project is going to be planning and building a custom case.

yeah, the PCB is designed to act as a heatsink so allowing for some amount of convectional airflow is important unless you can fit a heatsink or a fan. RPi4 will get a new USB controller firmware in the next weeks that is supposed to reduce temperatures through enabled/better power management. I'm happy with my 4 so far, there are still other boards out there that do things better but those are useless to me without the community and long term support of the "original". eames fucked around with this message at 13:44 on Jul 1, 2019 |

The reported drop is only 3-4°C (or -0,3W idle) so don't expect miracles. It mostly helps with throttling during bursts of high loads. If you're going to run anything compute intensive then a heatsink with a small fan is the way to go, just be sure to check that the tape it comes with is thermally conductive. Lots of ebay sellers sell their heatsinks with simple double sided tape which acts as an insulator because good tape is more expensive than the heatsink itself.

I can only really use my RPi 3 on the colder months. Giving it any real work otherwise just makes it hit the thermal throttling, and eve then it can power on through that and die completely in about a minute. The RPi boards seem to be somewhat vulnerable to thermal runaway. Once the temperature goes up its really hard to get it down again.

There does seem to be a bit of variation in terms of thermal performance between individual pis. I saw one review where they had three identical devices running the same software. All three were showing different temps. I think the worst one was hitting thermal throttling. The best one was no where near it.

IIRC when I tried out the RPi TensorFlow my Pi3 would poo poo itself within about two minutes. I probably repeated the same mistake maybe three times before I remembered not to try it again. On the subject of heat, one of my Pi Zeroes is in a black plastic case roughly the size of two AA batteries. I didn't notice that the VNC server was pegging the CPU for weeks, because it'd only do it after the client was disconnected. The top of the case has a small but noticeable sag now. Oops.

My Pi 3B+ overheats and usually won't even boot when I overclock it, but I stuck a little fan on it and it seems to run just fine like that, even doing something rough like running PS1 games. I also have heat sinks on it, but alone, they aren't enough. Not sure if a fan alone would do it.

I’m a bit hamstrung by the fact that whatever method I use will have to stream out of a cellular modem unfortunately. Thanks a lot for that GitHub link, I’ll download that and test it! The other big question I have that I’m hoping somebody might be able to answer is, is anyone aware of methods to get millisecond level timestamps onto Pi streams? I found something that I believe will work for the receiver side (just need to test it tomorrow!), but if anyone knows any ways for the Pi that would be great, right now I can get down to the second for both sending and receiving but I really want to get down to millisecond level precision and don’t seem to see huge amounts of gstreamer documentation for that.
