If you got a 3B+ from PI-TOP during their sale, I asked when they're shipping out and they said there's a shipping delay getting from the UK to their shipper in the US. The UK shipments are going out now, but the US will see them around the end of Sept or maybe early Oct.

VictualSquid posted:Crazy. A few years ago I ordered a 0W from them, which was one per customer. And I added a normal 0 to meet a shipping minimum, I could have bought a whole box. I don't need wireless, since I'll be using the USB Ethernet to connect to the USB port on my router, which can be done by emulating the device ID of a supported LTE modem. Then I'll run Pi-hole on it, from a single USB connection. Mostly just because I can.

The USB port powers the Pi as well, that's the idea. It can supply 1A, and a Zero needs less than 300mA (probably less than 200mA with HDMI switched off etc), even at full tilt. You can power it through either micro-USB port, not just the one that says "pwr-in". That's how USB gadget mode works.

I know about the low power. The heart of my audio system is a Pi0W that runs of an old 500mA charger I got for free with my first smartphone. Which is why the Pi0 is the best Pi. Didn't know that you can power it through both ports. That is seriously cool. VictualSquid fucked around with this message at 10:16 on Sep 17, 2022 |

https://ubuntu.com/blog/canonical-enables-ubuntu-on-starfives-visionfive-risc-v-boards Previously, Ubuntu had promised support for a RISC-V board that goes for about $179. https://www.phoronix.com/news/Ubuntu-22.10-Sipeed-LicheeRV Well, for those of you who are looking to do RISC-V on the cheap, Ubuntu 22.10 is going to support a $17 board that's 1 GHZ and 512 MB RAM. I imagine that real solutions would use yocto or buildroot to build a cut-down version of an OS for production use but an Ubuntu image would certainly be useful for prototyping.

The Pi-Hole on a Zero works great connected via USB to my router, emulating a supported LTE modem, thanks to this guide. It's using Unbound for DoT to Mullvad and UcensoredDNS, plus Log2RAM and disabling everything not needed (HDMI, LEDs and so on), to make it as lean as possible. IP is 10.53.53.53, just because I can  It's replacing a Pi3, which joins my stalwart original 26-pin Pi1 for various fun and projects. Now I just have to pick which projects those are.

I expect them to probably cross compile and test the main packages, which is but a small subset of the total packages available to the average ubuntu user on x86. Many of the commonly used services and software are in the universe and multiverse repositories.

The problem with the D1 is that it has the most rudimentary 2D graphics subprocessor, or at least the graphics leave a lot to be desired. I forget the 2d graphics subprocessor tech they're using, but I think when I checked it dates back to the 1990s. That is not an exaggeration These D1 chips are good for validating your code/toolchain compiles/runs RISC-V but there's no functional GPU in the D1 Haven't tried attaching to the RISC-V X server from my laptop yet though Looking forward to the D2 or second gen chips though

That is not an exaggeration Yeah, graphics tech feels like it would be just as hard as cpu tech, so I'm not surprised that it's not seeing any love until the cpu becomes stable. There's work on some open source gpu cores but it could take awhile until a truly free core becomes available. On the other hand, maybe they could incorporate PowerVR or something, since they seem to really want to be a part of the RISC-V ecosystem. At any rate, updating a cpu to have both compute and graphics cores is gonna be a tough task for a fledgling system.

And then it's going to really start pushing out ARMs for the main CPUs for a lot of things! Huge growth potential.

Once you get the shipping notice it will be quick, they used DHL, so 2-3 days tops. now that I've got it, I can actually start playing with my UPS hat. I'm not really much past doing some micropython and setting up octoprint, so I'm still reading docs. it's a Pico HV3.0B on a 3B+, and they recommend running their NOOBs image, but I'm hesitant because I've never used it before? Right now, I've got the pi as my octoprint server, so to enable it without reinstalling I've been reading through their github looking for dependencies. https://github.com/modmypi/PiModules/wiki/UPS-PIco-Installation but I also stumbled on this guide someone made for using it with Volumio https://community.volumio.org/t/guide-ups-pico-hv3-0-by-pimodules-modmypi/7512 but honestly it seems easier to just set up a new SD card, run the NOOBs UPS installer then install octoprint and import my system backup? I guess I'm dealing with an embarassment of riches here, because there are so many ways to get this job done. Just want to see if anyone with more experience thinks one way or the other is the better learning experience vs the quickest route vs the safest route.

I think the only non fully open part of the rpi is the binary blob bootloader for the GPU (which the CPU is slaved to, not the other way around), and someone has an alternative for that which can even play doom now so it's fully open if you absolutely want it I think there's some proprietary crap attached to the allwinner D1 simply because they had to bootstrap a RISC-V chip from something, but I suspect the D2 etc will leave legacy trade secret blobs behind it's just expensive and time consuming to do so

RISC-V isn't really a solution to any of the supply issues. Arm-based SBCs are abundant, they just have sketchier support. Pick up a NanoPi or an OrangePi or an Odroid.

I'm not sure how many people are running a Pi-Aware or ADSB setup, but found this guide on getting it all running on docker. https://sdr-enthusiasts.gitbook.io/ads-b It took me about 10 minutes or so to get a new setup running and feeding four different sites. Now I'm going down a rabbit hole of wanting a better antenna that I can stash in my attic and hopefully get more range. Another bonus is I've got everything running on a SFF Lenovo so managing it is easier than dealing with my stack of pi's. Edit: Not sure if this is cool. I'll edit it out if asked, but I've got all my old pi's up in SA-Mart right now in case anyone wants to pick one up for semi-cheap. diremonk fucked around with this message at 03:49 on Oct 6, 2022 |

Is there a good guide to learning the tools to manage a RPI? I suppose dummies guide to being a good/responsible linux admin? I'm currently running octopi headless, but yesterday it restarted without telling me why. occasionally, the we front end will stop responding, etc. I have learned to use the event logging functions in windows, but have yet to dive into logging and notifs on raspbian. How do I track down what happened? or put in place the tools to diagnose the server in the future?

Vaporware posted:Is there a good guide to learning the tools to manage a RPI? I suppose dummies guide to being a good/responsible linux admin? The first thing to know is many Pi distros only log to ram, not disk, because SD cards are fragile and constantly writing logs to the card has potential to kill them. So a mystery reboot will tend to stay a mystery. The equivalent of the windows event log on linux is the systemd journal, viewed in journalctl.

The most recent raspberry pi OS by default writes both the journal and the syslog copy to disk, unfortunately. Eat poo poo, SD cards.

Rescue Toaster posted:The most recent raspberry pi OS by default writes both the journal and the syslog copy to disk, unfortunately. Eat poo poo, SD cards. The base RaspiOS is a general-purpose platform though, if you're using that you either want to be running additional storage besides SD or setting things up yourself in whatever way that makes sense. Or you're using it for development and so logs that survive a reboot are more important than SD cards surviving a power loss. AFAIK most of the distro images built on raspiOS -- pihole, homebridge, audio players, etc -- are set up to only log to /var and OctoPi appears to do the same.

Looking through the logs I think it must have been a networking problem because I don't see a reboot at the time of the event. Thanks for the link, I can explore that command and the endless wonder of log greppin

Even a high-quality genuine SD card is vulnerable to getting powered-off during a write and either corrupting or at worst destroying the card. Flash storage just does not deal well with half-finished writes or erases, it's an inherent vulnerability of the tech. Real drives have capacitors to protect against this but a tiny SD card has no space for that. So yeah just a small eMMC drive would be an upgrade in reliability even if it's no better in any other respect to SD cards.
