I can look up the script if you need it

Turns out if you feed a Pi 2 24v it'll just happily sit there not turning on until you realize the buck converter isn't in line with it. Even the USB dongles survived me.

I saw this on slickdeals. A couple of years back, a company made the Pi Top which was essentially a laptop shell that worked with a Raspberry Pi. They seem to be selling off the remaining kits that require a Raspberry Pi 3B+ (but do not include one) for $45 with free s/h. They have some kits with the Pi 3B+ for $115. It comes with a 14" 1080 screen, keyboard with trackpad, battery, cables/boards to support all that and a green case. It's not a bad deal for all of that but to use it as a Pi-top you'll need a Pi 3B+. I have one so I may pick it up. I figure the parts are easily worth the price even if I don't use it as a laptop since that's not going to be a great laptop. No idea how many they have but probably not a lot if they're selling off the remaining kits so they can move on from Pi Top 3 to Pi Top 4. https://slickdeals.net/f/15941356-p...d?src=frontpage https://shop.pi-top.com/collections/pi-top-3-summer-sale/products/pi-top edit: they do have some that include the Pi 3B+ also for $115: https://shop.pi-top.com/collections/pi-top-3-summer-sale/products/pi-top-3-with-raspberry-pi-3b additionally if you buy one of the kits this pi-top speaker is free if the kit is in your cart, you just add this too: https://shop.pi-top.com/collections/accessories-for-pi-top-3/products/pi-topspeaker Rexxed fucked around with this message at 03:47 on Jul 29, 2022 |

I could use a recommendation. Looking to setup HomeBridge + PiHole on a single Raspberry Pi, wired Ethernet, running headless. I would also need some kind of enclosure for it most likely. What would be the recommended Pi for me to source?

I did both functions on separate pis, but that was before the chip shortage messed with the raspberry pi supply. Maybe you could swing it on a pi4?

Pihole is next to zero resource use, so a 3 will easily do both of them. Homebridge even works on pi zeros as long as you're not doing stuff with IP cameras or other video. Hardware power isn't the problem, it's managing the software. To run both at once you're probably gonna want to get into docker. There are docker images for both of them. TBQH since you're going to be using a more generic OS image + docker, you might even look at alt-pi boards like a le potato or various chinese pi knock-offs. Normally the downside of those is that you can't use a pre-made image for pihole or that you just flash to the SD card. But if you were starting with a generic Rasbian and adding docker, it would be almost as easy to start with a Clone-Pi's generic linux. Probably. This depends a lot on your tech expertise and how much time you're willing to spend fiddling on stuff, versus your patience waiting for real pi stock at non-stupid prices.

Hey thread, I've got an issue with a raspberry pi zero W. Here's the setup: The Pi is plugged in to my tv via the USB gadget, and a custom USB cable with no power lead. According to the TV, the Pi is a USB thumb drive. The Pi itself is powered by an official raspberry pi power supply (5V, 2.5A) which should be far in excess of the power it needs. It is hosting an SMB sharefolder that allows me to remotely add files to the "USB drive", so the TV can access them. Now, everything is working but after a few days, I am coming back to find that the Pi is powered off (nothing on WiFi, no "USB stick" in TV, LED off on the board). I have to unplug and replug the power cable to turn it back on. I've had a little bit of a look in /var/log/ at syslog, syslog.1, messages, messages.1 but I can't see anything to do with a deliberate system shutdown. Any suggestions about where to look, or speculation as to possible causes? I guess it could be overheating? I have it the "official case" red and white enclosure, but it doesn't have a heatsink. It's in a closed cupboard, but it doesn't seem particularly warm in there - and besides, isn't this thing meant to be low power? I don't think it's browning out, as the power supply is overspecced for it. edit: I am going to (attempt) to turn on the hardware watchdog for now and see if that makes the problem ignorable.

I would try disconnecting the USB cable to the TV for a few days and see if the Pi ever powers off. I can imagine some possible causes from that connection, for example voltage over ground, that could be responsible. You need to isolate causes, and the TV side seems like the most likely hardware cause. A pi zero doesn't need heatsinks or to ever really worry about overheating, so it's not that.

Not a worry. Pi’s are great little things but SD cards are not great but serve as a decent means to an end. Lots of weird behavior can usually be accounted for either: power weirdness or SD card weirdness. Log2ram cuts back on how often your system is writing logs to disk by storing them in RAM and doing periodic writes. This does have a bit of overhead in memory, but it’s pretty minimal. Similarly if the pi loses power unexpectedly you may lose some logs, but that’s usually an acceptable risk.

This is a brand new card, but at 32GB it's entering the territory where they start trading reliability for capacity. I'll set up log2ram and back up my image again.

I saw that there's a RISC-V powered raspberry pi zero W clone for sale. Ordered a 1GB ram model, has WiFi and Bluetooth, some kind of mini HDMI and two USB-C ports, plus standard 40 pin raspberry pi pinout. Oh and it's an allwinner D1 CPU/soc   Booted right up, this is a RISC-V build of Armbian Linux dated July 28, 2022 The silkscreening on the PCB says 20220627 so it's pretty new The big deal is that RISC-V is a totally new clean sheet CPU architecture, it is neither x86/x86-64 based, nor is it ARM. The CPU spec is also open source, out of Berkeley, kind of in the spirit of BSD https://en.m.wikipedia.org/wiki/RISC-V random article: https://circuitdigest.com/article/understanding-risc-v-architecture-and-why-it-could-be-a-replacement-for-arm Ordered it here, was about $40 shipped and arrived from China to the east coast in less than 2 weeks https://m.es.aliexpress.com/item/1005004372856686.html Haven't been able to play with it further because it prompts you to create a password and in 2022 I no longer have a USB keyboard so that's on order too, whoops

Haha yeah they do not mince words RISC-V support is coming along nicely in linux, but this is very much still a development board This guy seems to be the current (and only?) authority on the board https://bret.dk/armbian-on-the-mangopi-mq-pro/#0-the-images And then some benchmarks against the Mango Pi ("MQ Pro") and the Pi Zero W, looks like... it is ~80-120% the speed of the Pi Zero W, benchmarks are faster in some areas, slower in others https://bret.dk/raspberry-pi-zero-vs-mangopi-mq-pro-benchmarks/    That link has probably 30 more graphs if you're interested. Of note, the RISC-V idles using ~16% less power and ~26% less power at load, which might be interesting for battery users out there (if you're willing to manually recompile your custom apps in RISC-V)

Apropos of nothing, I just pulled out an old box from my basement and was treated to a not-insignificant pile of OG and early-gen Pi boards. So many aborted IoT projects and incomplete clusters, so many memories. Probably e-Waste time to fend off the technology hoarding instinct. I’m not even sure what you could do with a 2012-2014era Pi today, but it’s safe to say if I haven’t had a need to use them in the past six or seven years I won’t suddenly develop one tomorrow.

A Pi 1 is effectively the same thing as a Pi Zero non-W, so yes painfully slow if you're trying to make a tiny compute cluster. Totally fine for people who want a PiHole or other low-impact headless application.

Classic "why spend the extra money on a raspberry pi when I can get a clone for half the price" boondoggle There are approximately 8-15-ish Armbian RISC-V images floating around on the internet. One of these renders text correctly, not zoomed way in, I've lost track of it can't find it anymore. Makes it almost impossible to use the cli without typing "clear" every five commands to keep the cursor on screen. I hosed up my locales and reflashed the sd card and... I have no idea which image I used, can't find it anymore The only other Linux image that will boot on it with correct resolution is the official Ubuntu image but it doesn't have the drivers working for the WiFi chip  Should just copy the driver from Armbian to Ubuntu? Not sure why it worked on the one version (nightly build) and not any others Left a message on the Armbian RISC-V thread, hopefully some random Russian guy/moderator takes pity on me and fixes the problem. I think he has the mango pi physically so should be able to reproduce the issue Anyways this is why you spend the extra $$$. So you can actually work on your project, not gently caress around with compiling display and network drivers for exotic CPU architectures for hours

Yeah one of the key lessons of rpi clones is that genuine raspberry pis are actually pretty good value. The clones are half the price but half as good. I'm hearing a lot of buzz about RISC-V (at work too), and here I thought ARM was going to take over everything! My pi zero W is behaving now the Watchdog has been set up. I haven't checked the logs to see how often it's rebooting, but tbh I don't care. I've just set up log2ram (thanks for that advice!) and I'll put it back into service soon.

It's funny to read these posts, while my coworker has been using a RasPi connected to a TV as his remote workstation for the past three years since the covid quarantines started. I think he has mentioned it's the 256MB version. But he has always had weird masochistic tendencies. My department is moving to a new office space with rotating office seating, so everyone has to stuff their powerful desktop in random closets and get new ThinkPads. Not him, he plans to carry his trusty RasPi to office for the days we can't be remote.

The biggest drawback was web browsing. JavaScript performance was abysmal and having more than three tabs open had the system using swap space. Anyone doing that today has to be a masochist, I don't know how one could work without a performant web browser. If a job exists that doesn't require web apps that's great but it feels like it'd be a rarity by now.

RISC-V has the advantage of being royalty-free, so there’s no gatekeeper to collect a fee for your use of the ISA. RISC-V is also less mature - performance lags behind ARM chips from years ago and I don’t recall whether they added SIMD instructions to the spec yet or if it’s still under discussion. RISC-V’s software stack is also behind ARM at the moment. It’ll be a big deal for the embedded space and I predict it’ll vie with ARM for a lot of commodity devices, but it’s in flux right now. I wish more of the people insisting that it’s going to be the basis of a high performance architecture Real Soon Now could get excited for OpenPower instead, it’s in a much better position to execute there. Pi’s are fun! I wish I’d kept the Pi 4 I had, but a friend needed one and was squigged out by current prices, so I sent it to him. It’d be interesting to see how Vulkan support is coming along.

Maybe worse. I'll have to do some more checking. Clockwork has a version of Raspbian that will play doom at > 5fps on a D1 so something is off still Ran out of time to try more lighter weight wm.

it was only now when I realized that you had circled the hardware name but I've been out of the driver development business for awhile and it didn't click I have an audio driver (mic and speaker) for rpi that I want to forward port to a newer version. It uses dkms and doesn't work with newer kernels out of the box because they must've changed the audio API at some point. Guess it's as good a project as any to keep my skills up to date.

Yeah I'm gonna take one more stab at it tomorrow see what's up with the clockwork distro it's based on Raspbian, frame rate seemed pretty good The D1 just comes with a 2d graphics core, I think it's from literally 2002 pretty grim. Probably gonna have to dig up a raspberry pi a+ out of the attic to get this project done And yeah it's RISC-V everything is super janky there's like 1000 people worldwide that have more than 24 hours using this stuff. Apparently it's way way better than it was back in April Hopefully the D2 gets a 3d graphics core but I'm not holding my breath they just released this thing and still doing revisions.

they probably want to get a lot of chips out on this revision so that they can work on both the manufacturing kinks and a new asic at the same time before they go full throttle. As long as people are buying these risc-Vs, might as well sell 'em! I bet there are plenty of embedded development folks that still want to get their hands on these things because RPIs are even more rare than Bigfoot these days. Particularly for university courses and whatnot.
