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 used mine along with the 7" touchscreen as a live photo frame connected to a google photos album when my mother was ill from Alzheimers.

I've gone to unholy ends to syncronize large herds of Pis using a patched NTP server and several other dirty tricks. The RTC is a huge deal to the people who care about it.

Do you mind delving deeper into this RTC for those who don’t care about it (yet?).

Happy to answer specific questions not already covered in this thread.

I hope this will play videos without coughing. I tried hard with the Pi4, but in the end I gave up using it as a desktop computer.

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.

The audio jack on Raspberry Pi's has always been terrible quality anyway. Ok in a pinch but it's not a huge loss. If you want quality analog output from a Pi you need a DAC hat.

Yeah, that's true, and I did that when I built a 'streamer' from a Pi 2. It was great. At some point though the quality of the built-in jack did improve, and so when I built a sound/lighting effect box for a toy theatre with the Pi 4 it was plenty good enough to use, and made it simpler and cheaper to put together.

There are loads of cool projects for the Pi (synths etc) which chuck out audio and sound good enough through the built-in jack.

that definitely sounds like a whinge. raspi is fundamentally an unfinished, everything-not-included product. most use cases require some sort of dongle, hat or other adapter. an audio jack (especially in a context where you're not using an HDMI device that you can get the audio from) is much more niche than a lot of other things that aren't included on-board, like storage or POE. if it's a trade between a built-in au…

fair enough, i suppose i'm interested in using it for mainly audio/music applications and so am biased. no use for an RTC. demonstrates really how hard it is to keep everyone happy! over the years i think they've traded things off fairly well.

So if you need 3.5mm output you need to buy some accessory? That's disappointing - reminds me of what happened with phones.

i still won't buy a phone without one! i wonder how long i'll be able to hold out...

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/

Teensy is BRILLIANT - but a bit different to the Pi. It's quite convenient to have a 'real computer' you can toy around with directly on the device.

If you're using a pi you're already in a pinch, putting a dac on a pi seems alot like putting lipstick on a pig, the only scenario where it wouldn't be overkill is music streaming and i highly doubt thats even a majority of pi projects with audio

You can plug a 5€ USB audio adapter. That's what I have always been doing.

probably the way to go, but 'another thing to plug in' if you're building something for someone else to use

Do you have a guide or any tips on how to do this?

It's called PXE boot. You need a server to host the ISO (via http/ftp/tftp or whatever you prefer) and a DHCP server that will distribute the ISO URI to the client. Configure the client to boot from the network in the bios and put it in the same LAN as the dhcp server. That's the gist of it.

Raspberry Pi's don't use PXE boot, they have their own proprietary system. The kernel is fetched by TFTP, along with a config text file which species an NFS location to mount as root. Boot then continues from there.

I have fallen out of love with Raspberry Pi due to the performance. In desktop mode, I have found it too lacking to be any fun. It even struggles to run the web browser. And things like Mathematica, that you get for free which is awesome, are just much too sluggish to be very much fun.
