Extremely dumb question, so apologies if this has already been asked, but will the Pi 5 be compatible with images created for other Raspberry Pis? Notably the off brand pis (like orange pis) are not, which really limits their usefulness as a plug and play device.

I dunno how you would design a 3.5mm jack that can smartly switch between line and headphone. I don't think line level has some magic resistor in the plug. USB-C does have a "headphone out" resistor pin drop spec that allows it to function as a headphone out, but I don't think it can magically switch between headphone and line out

There's no "magic resistor" but the difference in impedence between a speaker and an amplifier can probably be detected by a fairly simple circuit. How many devices actually do that I have no idea.

It'll need a newer build of the base OS (mostly the kernel for the new hardware support), but basically everything else laid atop that base should "just work" unless it's getting down and dirty with the hardware.

If your image of choice is being regularly updated more likely than not the next update will support Pi 5, if it's some abandoned old thing you're probably SOL.

What do you mean �drive a speaker?� It�s a headphone-level output that IIRC operates in line-out (ie line level) mode when plugged into the right resistive load.

You�ll need to power your speaker, so maybe something with an onboard amp will be better for your needs. Probably shouldn�t drive the speaker straight off the rPi (are you doing that with the pins?)

Well the thing was that in my original post I said I was trying to drive a speaker and that driving it with the onboard PWM is very quiet because it's only putting out enough power for headphones:

Fooling around with a Pi 4 and an 8 ohm speaker hooked up to GPIO pins (dtoverlay=audremap,pins_18_19 in config.txt). It is, of course, very quiet.

I ended up buying an Adafruit I2S amplifier hat (https://learn.adafruit.com/adafruit-speaker-bonnet-for-raspberry-pi) because the price was good and the hat seems pretty convenient, and I could get it delivered tonight from Amazon.

Oh yeah speakers come in 4 and 8 ohms typically don't they good point

USB-C has the ability to measure resistance on at least some of the pins, that's how adapters are passively coded as part of the spec

Ok I looked it up, voltage negotiation is done via kiliohm values, like 12k, 36k etc. https://hackaday.com/2023/01/04/all-about-usb-c-resistors-and-emarkers/

I can't link to the PDF source on Mobile but Texas instruments says it's a 1kohm value for audio devices. I don't know if the USB-C connector is smart or sensitive enough to pick up an 8 ohm resistance since the other values are presented as +/- 10% which is like 120+ ohms

Stop. Just stop.

The speakers or headphones are not connected to the USB-C plug.

My google skills suck or such a thing doesn't really exist.. anyone know of a pi camera ribbon cable that is less fragile? I'm always worried about creasing the ribbon or it getting otherwise damaged which I wouldn't worry as much if it was in a round flexible sleeve.

I do see some DIY and even a couple hdmi cable conversions so I guess other people have tried to solve this.

Rescue Toaster: Mar 13, 2003

I'm genuinely curious to see what the Compute Module 5 ends up being. I wonder if there's any more PCIe lanes on the cpu that they could bring out. The CM4 and Pi 5 only expose 1 lane, but the Pi 5 processor has at least 4 more lanes going to the 'southbridge' for lack of a better term. Seems odd if it had exactly 5 lanes, so I'm cautiously hopeful we might see 2 lanes (dare to dream) exposed? That would mean changing the pinout of the CM4 connector though, which I don't think they'll want to do unless perhaps something else was obsoleted anyway.

Running a pi zero 2 w, after a couple days it fills up all 32GB of storage, and stops responding. Also very warm. I kill the power, let it cool down, and it'll boot up, but that storage is swamped.

code:

tmpfs            42M     0   42M   0% /run/user/1000

It's running Raspberry Pi OS Lite (64-bit). After a clean install, I ssh in and do the following:

code:

	1.	sudo raspi-config, update, enable i2c
	2.	sudo apt-get update
	3.	sudo apt-get upgrade
	4.	sudo apt-get install unattended-upgrades
	5.	sudo dpkg-reconfigure --priority=low unattended-upgrades
	6.	sudo apt-get install i2c-tools # doesn't appear to actually be necessary these days
	7.	sudo apt-get install pip3
        8.      pip3 install a couple libraries from below script

I then dump the following python script into a file and add it to the crontab to be run once a minute:

code:

from datetime import datetime, timezone
start_time = datetime.now(timezone.utc).replace(second=0, microsecond=0).isoformat()

from time import sleep

AIO_USER = 'me'
AIO_KEY = 'dirty_secrets'
aio = Client(AIO_USER, AIO_KEY)

aio.feeds('fish-temps.controller')
cpu_c = CPUTemperature().temperature
cpu_f = cpu_c * 9/5 + 32
aio.send_batch_data('fish-temps.controller', [Data(value=f'{cpu_f:.2f}', created_at=start_time)])

probes = ['ambient', 'water', 'heater', 'bubble']

for p in probes:
    aio.feeds(f'fish-temps.{p}')

samples = 100
totals = [0, 0, 0, 0]
for i in range(samples):
    for p in range(4):
        totals[p] += adc.read_adc(p, gain=1)
    sleep(0.1)

A = 1.217808990e-3
B = 2.164964415e-4
C = 1.820024468e-7

for i, p in enumerate(probes):
    R = totals[i] / samples
    t_kel = pow(A + B * ln(R) + C * pow(ln(R), 3), -1)
    t_cel = t_kel - 273.15
    t_far = t_cel * 9/5 + 32
    aio.send_batch_data(f'fish-temps.{p}', [Data(value=f'{t_far:.2f}', created_at=start_time)])

I see three symptoms:
- The crash
- The heat
- The storage

Not sure which is causing which. Like, is it maybe overheating, causing some logs to fill up the storage, and eventually going kaput? Or is something filling up storage, causing it to overheat and go kaput? Or is it going kaput, and in the process overheating while loading up storage? Once I settle it down and fire it back up, even though storage is 100% full, I can ssh in and tinker around more.

Looking at where the storage has gone, it appears to be logging eating it up. /var/log/syslog.1 is ~14GB of

code:

Sep 25 18:18:03 fish kernel: [24199.189100] brcmfmac: brcmf_sdio_htclk: HT Avail request error: -110

with this message being logged apparently as quickly as possible, thousands of times a second, or more. It also logs every time my cron runs, once a minute. That's small beans in comparison, but it will add up eventually, and I'd like to address that, too.

The other half of the storage (another 14GB) goes to kern.log.1, with the same exact message, at the same exact rate:

code:

Sep 25 18:18:03 fish kernel: [24198.691127] brcmfmac: brcmf_sdio_htclk: HT Avail request error: -110

Googling the error in question, I can't seem to find much. Maybe related to wifi? But also claims that it should have been fixed a while ago.

Swear to god, I'm going to add a second cron that just deletes that log file.

Looks like that is an error with the wlan driver.

Looks like that person was also running a lite distro and it was missing some files related to that driver. Might be an issue with the lite distro or it has been reintroduced somehow.

That aio.send_batch_data() command hits the Adafruit IO servers, as does aio.feeds(). But that all works just great for a while, until the whole thing crashes down. Looking at the data that does get logged to Adafruit IO, it looks like it actually goes down sooner than I thought, like less than 24 hours after startup.

you may want to consider calling journalctl to prune the logs so that you can be sure they get rotated and you actually save space (since deleting an open file will not get rid of it until the file descriptors to it get closed).

USB-C, adapters

So this is all irrelevant to Pis because they don't support passive analog audio adapters, and the Apple adapter that was mentioned is not one of those.

But the signalling for adapter type uses the CC pins, while the audio itself goes over the data and sideband pins. So it's easy to measure the resistances completely separately.

E: I guess you're talking about the audio signal for passive audio over USB-C, though. Which makes the first part of my rant less relevant.

Which still isn't happening, because there's a DAC in-between and no direct connection between any USB-C pins and the 3.5mm output jack.

Some audio adapters can sense the impedance of headphones and switch to a higher output setting if necessary. I have one that does that, the Meizu Hifi Pro. It can drive 600 ohm headphones without too much trouble to a good volume level. But the Apple adapter doesn't do that and can't proper drive such headphones.

Both the Meizu and the Apple are perfectly fine to connect to an amp to drive speakers. They're just variable level outputs with lower source impedance (that's good) and the ability to deliver more power (also good, and the high input impedance of a line-in means it won't hurt anything).

A headphone output is perfectly fine to use as a line-out, as long as you don't use a powerful headphone amp that will exceed normal line level. The Apple adapter only puts out like 1 Vrms maximum, compared to normal line level which is 2 Vrms. So worst case, you'll just have to turn up the volume on your amp a bit more than you would otherwise have to.

A thing to consider setting up long term is log2ram, at least once you have everything else working and stable.

In-progress writes during a power failure are great for killing sd cards, and logs are writing all the time. Most pre-made special purpose Pi stuff (pihole, retropie, etc) come set up with log2ram. The general-purpose raspian / PiOS doesn't though, because when your logs vanish after a crash it makes debugging v hard.

# ? Oct 3, 2023 19:06

Another valuable SD card saving tip is to set up a shutdown button. By default if you short pins 5 and 6 it'll issue an immediate system shutdown. Or hook up a button if you wanna be fancy.

I know we've all rolled the dice, gotta unplug the pi and you don't wanna hunt down a keyboard or ssh in so instead you yank the wire. But if you had a power button it's right there and you got no excuses.

Or modify your syslog config to forward logs elsewhere rather than writing them to disk. There's a whole host of poo poo out there that can do this (I'd, uh, recommend against Splunk following the Cisco acquisition lol)

edit: for home use you might just be better off setting up rsyslogd on a Linux box with a real hard disk, and just forwarding everything from the rpi to that.

FWIW, I have a pi running VolumIO upstairs for the bedroom and I hooked up the line-in of an amp using one of those HDMI -> VGA/Composite adaptors that does audio as well. It chugs along and works / sounds great.

Does the thread have a recommendation for something to power 4-5 Pi�s in close proximity to each other? I found a pi rack mount thing for cheap and want to put my pi�s in it in an organized way and power them all from the same adapter. I was thinking about it and I guess the theoretical max draw could be something like 10 amps at 5V? lol. So I�m hoping to get something that others have used and not burned their house down.

If you're going rack mount there's always PoE, which also gains you the ability to remotely power cycle your Pis individually.

Otherwise I'd just look for a multiple USB power supply that fits your needs from a major brand like Anker. I have an Anker 6 port unit that has run a few Pi 3Bs and two streaming sticks at one time with no trouble. My 4 has always been PoE.

If I were to consider using a Raspi for a home theatre setup, is that an actual good solution?

Some considerations:

I have a projector that is only 1080p, and probably won't be upgrading any time soon. HDMI. So this part is no problem.

I will need to add a system of speakers. Ideally 5 around my place, along with a subwoofer. I have all the speakers, with the little automotive wire terminals. I also have a beefy amplifier with those terminal outputs, along with a ton of speaker wire. The amplifier can input HDMI, or some other formats I think.

The main problem is that I really do not actually want to run wire everywhere. I feel like, given a month or two (and lack of other commitments), I could hack together an RF system with a little amplifier for each speaker, so surely someone has done this already.

Anyway, I don't know the best to do this within my constraints (and cheap, ideally), and that might be out of scope for this thread! I also have an old Chromecast, which might be the better option, but I haven't played with it in a few years with which to see what kinds of things I can actually cast to it (random-rear end web video players, ideally).

A Pi is fine for a source device, literally any Pi ever made will do 1080p without trouble and the 4 adds 4K. I used a bunch of Pi 3s running OpenELEC for years as as an upgrade from an OG Xbox running Kodi until I migrated to Plex a few years ago and it was great.

I'm trying to keep costs down since I don't really have any idea what I'm going to use these Pi's for anyway. I used to use them for a bunch of stuff, but ended up setting up a couple of old laptops as a home lab and everything runs on those in containers now.

Is the pi4 8gb good enough for surfing around and watching youtube videos at 1080p? I'm currently running an old TV in my "lab" (spare room) using an ancient chromebook (Acer C720 I think? celeron processor) running Lubuntu and I'm curious whether a pi would be better in any way.

Unless you want to run a full-on computer through your projector (and are OK with getting max 720p on streaming services that use DRM), I'd definitely suggest the Chromecast option. Or get an Onn 4K Streaming Box from Walmart for $20 which does all the modern codecs you would ever want to stream (H.264, H.265, VP9, AV1), doesn't rely on a phone (Google TV is basically a stripped-down version of Android with a TV-focused interface) and should have apps for every major streaming service. It's basically the same as the $50 Chromecast With Google TV 4k except it has a slightly slower CPU and no support for Dolby Vision or Dolby Atmos, neither of which it sounds like apply to you.

Does anyone know if it�s possible to tether an iPhone to a pi in order to get internet?

It looks like the answer is yes, but you need to install some extra software: https://wiki.archlinux.org/title/IPhone_tethering

Awesome, I�ll give this a try!

lol, why is documentation always like this though:

�from the doc above which I�m grateful for� posted:
