I wonder if Plex Media Server will finally use the HW codec. Probably not. But maybe this will be beefy enough to run Jellyfin (which does)!

I dusted off my 3B for a side project because my 4B is already engaged in one and it really reminded me how power hungry the 4 is. Yeah the numbers are right there on the spec sheet but it's still a wakeup to actually witness it. The 4 will use about 2% of my 25 mah power bank per hour and the 3B used 3% in three. Obviously workload matters but the two jobs aren't that far apart. The 4 runs an LCD hat and copies files off a mirrorless camera to a SSD and the 3 uses the pi camera to take a photo once every second. Anyways that was my fun for the evening. Timelapses are cool.

I really feel like the Pi B series is actually losing utility each new release since the Pi 4. Losing the full size HDMI means that it is not as convenient to use in a place where there are no mini HDMI cables. Increased power draw means they are not as useful in embedded or off grid applications, and they need more complex and less common power supplies that one might already have lying around the house. Yes, the loss in utility is offset by better use as a "desktop" but it still isn't a good desktop. It feels like that is the way the Pi B is going though. My wish for the next Pi B is that if they keep moving it in the direction of being a desktop replacement, the USB-C port can start supporting things like DP-alt mode and USB-3.2 or USB-4.

If I'm only really intending to use a raspberry pi as a mini desktop to tinker with, should I be waiting for the 5B? I haven't played around with one since the first iterations. (I think the one I have that burnt out is a B series?)

If you're comparing to the OG first gen RPi, there's been hyuuuuuge leaps since then. For one, they were single core, which everyone forgot how much sucked.

I've got an original Pi B (not B+) and it is indeed quite slow. Good enough for a Pihole serving a handful of clients, but I wouldn't run anything intensive on it. Maybe a simple webcam + web server and a temperature+humidity sensor to keep an eye on my greenhouse or something

The main thing that gets called out is that web browsing doesn't feel great. The Pi 5 is a lot faster. It's very similar to some high-end SBCs from the last year powered by RK3588 which had much better desktop experience (but more weirdness because all the not-Pis don't have Raspberry's level of software quality). But, thread title. If you actually want a general purpose desktop, a cheap $100-150 used micro-desktop business machine is still the best option in most ways. So for example if the goal is to learn linux and you just want a 2nd computer to do that with, get a real machine.

I’m kind of meh on the 5. The most notable thing about it is the possibility of getting a nvme on there to not have to deal with the limitations of SD cards. You could already accomplish that with the 4 and assorted cases though this would be performant. That said, thread title at that point. The price point is gone, the power draw stuff is gone. Eh. This said I have a 4 nvme setup and I greatly enjoy it as a headless general workstation server so chase your bliss.

(Or, for $250, you can get one with dual LAN ports and get into home networking poo poo.) Cheaper option, used Dell optiplex or lenovo thinkcenter, go on amazon or ebay and look for those plus "micro" or "tiny". There's a lot of options in the $100-150 zone. These are all gonna be used so check the seller ratings before you buy just in case.

If that’s the case then you’re gonna be way, way happier picking up a refurb office PC in whatever form factor (tower to USFF) from eBay or your local marketplaces for $80-$200 and just slapping whatever Linux you want onto that. Then you can decide later if you want to drop more cash on a new/more powerful Linux machine or you want to put a partition on your Windows PC, or whatever. USFF Optiplex or IdeaStation or whatever will be the bee’s knees for not taking up space and being cute, but you’ll be limited to onboard GPU, whereas something bigger will give you at least some options for adding a GPU and possibly messing around with Proton gaming/etc in the future (keep in mind that office PCs usually have very little power supply headroom and might max out at like 400 or 500 watts. You can often get upgrade replacements, often OEM stuff meant for Alienware or XPS bto or whatever, and they can be cheap, but also they are usually used/grey market and that poo poo gets sketchy fast unless you’re like actually overpaying for a PSU from Dell, etc. so prolly best to stick to a relatively low power GPU). I really like the look of SFF and low-profile cases but those limit you to low-profile GPUs at best and those can often be a bit pricey for what you get. A regular fat tower will give you the most flexibility if you plan on doing any kind of graphics upgrade.

The optiplexes are really easy to shop for. The first two digits of the model number indicate what generation CPU you're going to get, the second two digits indicate how many features it is supposed to have. This won't always be true, since these are going to be used machines so they have whatever the seller has put into them. But that's also really easy to figure out because it's just CPU, RAM, and SSD. Make sure that what you buy actually does have RAM and an SSD, because there are a lot of sellers that list their optiplex or nuc or whatever at the same price as everyone else but do not include RAM or an SSD. The rest is just looking at the picture in the ad and reading the description to see what else it has. The pictures will tell you what ports are on the front and back, and maybe if it has wifi or not. These things are great for learning linux because you can always just wipe and start over, and it's on an actual machine so you don't have to deal with any weirdness that comes with a VM.

Wyse 5070 "thin clients" are $50 or less on eBay if you just want a cheap desktop - they're Intel J4105/5005 with 2/3 4K-capable DisplayPort outputs, M.2 SATA, and the ability to run at least 16GB of dual-channel DDR4. Idle power is like 5-7W and it runs off a standard Dell laptop brick. e: I forgot but according to the spec sheet the Type-C port on the front is also a DP output. You can't use all of them at once, but if you really need that many monitors there's also the "extended" version which can fit a low-profile graphics card.

You can get power-only USB C connectors that would be possible to hand-solder (data USB-C jacks, no). But they're not the same dimensions as micro so it's not some drop-in replacement on an existing board.

I am not super excited about the 5, unless the GPU is just super amazing this time around Looks like it is on average 2x faster than the 4, anywhere from ~1.7 to 3.5x faster depending Will it be able to run chrome and gmail without complaint? I guess that's my benchmark at this point. But then, thread title A raspberry pi 5 in the "zero" form factor would be at least moderately interesting. There are a lot of things you could plug that in to for displays and a lot of software/electron apps that render using chrome's engine where a 5 zero would be interesting, particularly with like 8gb memory Thanks Ants posted:I'm going to sell a service clearly advertised as moving the surface mount resistor from wherever it is currently located to the 8GB position, making no references to the system memory. You and half of ebay Silkscreen might have been a thousandth of a cent more expensive but anyone with a soldering gun can now sell counterfit 8GB models at a $20 markup. Good luck getting a clean resolution with your online marketplace with that one. Hopefully it's not that bad and this is correctly handled by hardware

I suppose someone with a pick and place machine can get an assembly line going of fake 8GB Pi5s, but if they show a picture of it being in the 8GB spot, it will probably be somewhat easy to tell if it's been hand soldered.

The 4 is B only, and I assume the 5 will also only be B.

Had a few days to think, and I think I've cooled on the 5. It won't do anything substantially better than what I already use a Pi 4 for, which is a cheapo NAS. I think I've made the jump to caring more about what Compute Module Pis look like going forward. All the projects I care about were already using the CM form factor. And I probably would be more interested in the 5 if Alder Lake-N mini-PCs hadn't hit Aliexpress over the summer, I have an N305 mini PC on the way already.

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. Bought a little PAM8403 amplifier board from Amazon and while it's louder, it also picks up a hell of a lot of noise from the onboard wifi. If I plug in headphones and listen very carefully, I can hear the same noise faintly there. What's a better option for getting non-noisy audio out of this thing and into a speaker? I know it can do audio via HDMI, and then there's the option of a USB sound card... I assume most of my problem is that the wifi antenna goes right past the GPIO pin traces, because I only pick up noise when I'm actually connected to the pins (doesn't seem to be getting induced into the leads, I mean)

Low background noise all around.

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?)

I'm like 99% sure line level and headphone out are two different things. You can dial headphone out down to a line out where it's (mostly) usable but I definitely recall plugging the headphone out of my walkman into the line in of an old junkyard receiver in the 90s and blowing out the speaker because the walkman was set to 3/4 volume. Line out isn't designed to drive two 40mm "studio" over-ear headphone speakers with 'x-tra bass' 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 Hadlock fucked around with this message at 18:33 on Oct 2, 2023 |
