No word on price. When Raspberry Pi first launched, this was the prime feature of the thing. Can we expect same price as the Raspberry Pi 4? (at the respective RAM level) Edit: found it here: https://www.raspberrypi.com/news/introducing-raspberry-pi-5/ So the 4 GB model is 60$, which is 5$ more than the 4 GB model of the Raspberry 4 when that was launched: https://www.raspberrypi.com/news/raspberry-pi-4-on-sale-now-.…

My gripe is that the original Pi cost $35 at launch and while they have made a better Pi...They have not made a Pi at that price ever again, even accounting for Inflation. Furthermore, increased power consumption and features have added big price jumps to the required Accessories. Now you need miniHDMI adapters rather than more common HDMI, you need cooling, you need more expensive power adapters. a fully set up Pi 1…

Apple showed them that an ARM desktop is totally possible. And also that making the pi 2x or 3x times faster would make a great arm linux desktop.

It's more like they're expanding their top line.

I am curious to know how people here use their RPIs today, and how the RPI5 might help. I have had a model 3 for many years, which I enjoy tinkering with from time to time. I still haven't gotten over the novelty of having such small, cheap computer that runs Linux and does a pretty good job of it. That said, all I do is tinker with it. I turn it on, write a bit of code, marvel that the code runs, and turn it off. I'…

I'm using currently 4:

- One pi4 for my homemade 3D printer (a Voron)

- One pi3 for a homemade eInk clock/weather station (here I could've gotten with sth much cheaper like an ESP32, but the Pi is so convenient)

- One pi zerow 2 for a homemade eInk radio

- One pi4 I just bought for home automation (homeAssisstant)

> A NVMe compatible M.2 M Key connector Yeah. The Lichee Pi 4A has one of those under the board, it's really useful. I wouldn't even blink if they completely jettisoned the MicroSD slot, these have proven to be a giant PITA over the years (slow, unreliable, etc...) I really don't understand why they would miss that.

MicroSD allows for a really low cost deployment (availability issues aside), especially when PXE is not suitable.

For the low cost route, boot off USB flash drive.

Included in that 17% figure is the price increase for e.g. corn, rent and steaks. Why should the change in price of either of these things be relevant to the price of a Raspberry Pi?

How else would you define how much a dollar is?

I know this will sound like a whinge but it's really a shame they removed the audio jack, it was so useful for simple sound/music projects.

Removed the audio jack, what the? That's a fundamental misunderstanding by the hardware designers of what Raspberry pi is. Raspberry Pi has jumped the shark.

No. The pins are still there. My guess is most peole don't have a need for it.

You might look into the Teensy boards. There's an audio adapter that adds a DAC and headphone jack, and there's also an audio library. The Dirtywave M8 was built on top of the Teensy stack. https://www.pjrc.com/teensy/ https://www.pjrc.com/store/teensy3_audio.html https://www.pjrc.com/teensy/td_libs_Audio.html https://dirtywave.com/

It's a pity about Teensy3 being effectively gone. I've got numerous eurorack modules based on the Teensy3 12-bit onboard analog output.

The trick there is twofold: one, if you're doing traditional digital audio, this output has a very 'old school sampler' sound that takes well to further processing. It's a really primitive output with a lot of character that sits well in a mix or performance: no trouble building an entire mix around sounds coming off this output.

Two, because it's directly built into the Teensy and doesn't have as many intrinsic assumptions about what digital audio is, you can overclock it to sample rates as high as a megahertz or so, while still running the same audio library. That means if you're just putting out a square wave, the ONLY limitation on your quality is aliasing, as bit depth no longer matters. If you're doing multiple square waves you still don't need full use of the 12 bit analog output to do it. And if you're at 1mHz aliasing is next to nothing, so all of a sudden your cheesey 'bad' output is in fact shockingly good. Even waves which do require the 12 bit resolution are a lot better with no significant aliasing. I run four-note chords with two oscs per note, portamento, and additional waveforms, on a single Teensy, at upwards of 300kHz.

From what I can see, no audio hat does this. They're all mediocre CD quality. I'm sure you could build a ladder DAC out of raw digital outputs on a more modern Teensy and do just as well, especially if you ran even lower bit than 12 bit. Teensy3 has that analog pin just right there, though. Lovely :)

Someone buying used electronics on eBay has already decided that their time is worthless and the hardware doesn't need to be dependable out of the box. Which is fine, those are decisions a person could make, but it's just disingenuous to compare the value of one thing to another without taking the you are using someone's untested trash factor into account.

There are reasons to prefer a Pi over a used mini PC, but it is not reliability. The fact is that with Pis or PCs, _if_ you're still running after a week, you're highly, highly, likely to survive past the point of usefulness.

> The fact is that with Pis or PCs, _if_ you're still running after a week, you're highly, highly, likely to survive past the point of usefulness.

I might be hopelessly biased since you would regard me as someone who keeps using computers when they are "past the point of uselessness," which is not a phrase I'd actually use.

A lot of the stuff I do to keep computers running after a long period of ownership does not even apply to the Pi, which is nice. I won't ever have to replace the fans on one of my Pis (the case design of the prototype Pi 5s we've seen notwithstanding), but that's a standard thing on PCs. There's maybe one capacitor on a Pi's board? I've never needed to think about it. I've guiltily thrown away and replaced soft power supplies on PCs, even though I had a friend once who knew how to fix them and I should really learn to do the same, but there's considerably less guilt when it's a USB wall wart. I've pitched a few SD cards belonging to Pis over the years (never the proper SSDs, though) but that has never been nearly as painful as a drive failure in a PC.

So I guess I'm saying I would factor in the maintenance burden.

> The bias at play is that people see "old" and equate it with "bad performance".

I see "used electronics" and "eBay" and think of "wasted time," "frustration," "incompetence," "shamelessness," and "fraud."

The other thing I would factor in is that my time is worth something and eBay's main goal, when it comes to used electronics, is to waste it.

> In short, if you just need something to run Home Assistant or Plex on ProxMox or similar, you would find more reward in a mini PC than a Pi, particularly in performance.

I'd split the difference here and say I'd be happy to run Home Assistant on a Pi and Plex, quite possibly, on a PC (but I'd want to at least test on a Pi). I'd be happy to buy a new PC for the purpose from a trusted retailer, or build it myself.

I have a Pi 4 running Pi-hole and connected to a 4TB USB hard drive running a Samba server with a bunch of media. It’s on my Tailscale network so I can access the files away from home, and use it as an exit node if I’m abroad and need to access stuff as if I’m in the UK.

I don’t need to transcode anything so it’s been more than sufficient for me, and if I start to run out of storage I can just hook up more drives.

It also has about a terabyte of PS2 games because a softmodded PS2 can play games off a Samba server rather than the DVD drive. Niche, but very cool imo
