TBH the thing I hate most about this category of SBC is the reliance on SD cards. They are both too unreliable to trust and so slow that they often bottleneck the SBC. Buying them is often a crap shoot too, I've purchased cards batches of cards from the supposed reputable manufacturers that were all over the board when benchmarked, and rarely did they hit the claimed speed spec. I would love if there was an alternati…

With the 3 and newer you can boot from USB drives instead of SD cards. It’s a bit of a faff to set up but it works great.

I had to do this when I was doing some long-running I/O intensive operations and it was basically killing the SD card storage.

Not to mention it now requires a new PSU. Before you could use your standard $5 (android) phone charger at (5W), then you had to buy a 15W one and now a 27W. To whoever thinks pi's are cheap, you can get more functionality out of a used laptop for less money, but probably worse specs and probably x86.

The standard charger is 2.5W, not 5W, and RPi3 will happily run from that, for RPi4 2.5W is somewhat marginal, but it will still work. I suspect that RPi5 is going to be somewhere around 3W (non-PD USB3). The official RPi specs intentionally overblow the power consumption in order to provide an buffer for powering whatever ridiculous stuff people may hang off the USB ports. Then the other issue is that all RPis need…

The old standard Pi PSUs output up to 2.5 amps (not watts), which at 5V gives you up to 12.5W.

Older boards with simpler workloads could usually manage at 1A (5W) but it was always preferred to have at least 2A (10W) to work with.

The RP1 has one PIO core (4 state machines) https://www.raspberrypi.com/news/introducing-raspberry-pi-5/...

This RP1 chip has so many surprises.

If it was good enough for the Saturn V, it's good enough for me!

>Well the RPI has GPIO GPIO can be added via tons of USB to GPIO boards out there. But I agree - lot of people tend to buy the Raspberry Pis for home servers instead of just opting for used mini-PCs from secondary markets. Even a 7-8 year old Intel CPU in those mini PCs will vastly outperform a Raspberry pi. Even the Raspberry 5. Plus, better I/O options and storage with mini PC.

> GPIO can be added via tons of USB to GPIO boards out there. Depends on the use case. USB adds a few orders of magnitude more latency and jitter versus what's probably just APB.

Which only matters in very niche usecases though.

Most of the stuff just flashes LEDs or reads a switch. Doesn't matter for that. And for more intelligent stuff there's i2c or api which have their own interface boards.

You made me curious: what do use them for exactly?

One is the "smart" part of my smart TV. One powers my hifi. One connects my non-networked printer to the network. One is an NTP server which gets the time from GPS, although that one will probably be retired soon, internet time works fine. I used to have one inside a MAME cabinet but I upgraded it to a "real" PC because the Pi isn't really powerful enough for modern versions of MAME.

What do you use for the smartTV (distro)? And do the big streaming players work happily?

Sorry, can you elaborate? Is the death rate of NVMe drives known to be significantly faster than that of other types of drives? I hadn't heard of this.

I can only speak from my own experience, but there are a number of low to mid grade SSDs that use truly awful flash and/or controllers. I've bought many of them over the years for unimportant workloads, and have been unpleasantly surprised by how quickly I can burn them out. It's really worth it to shell out for higher end models just for the increase in durability.

Out of curiosity which brands?

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 have a raspberry pi zero wifi thats running syncthing and has a few of my syncthing folders/nodes on it. i already have a NAS that acts as the always-on node for all my syncthing folders, but if that is ever down for maintenance or whatever then the pi zero is sort of a backup that will keep syncthing things

i have another running kodi so i can access jellyfin that's on my NAS

pi-hole for network wide ad blocking

currently setting up one to act as a storage location for the restic backups from my NAS instead of having to store them with some storage provider like backblaze. i will be installing tailscale on it as well so i can leave it in a friends house and hopefully be able to reconnect to it even if they move house in the future

I wonder if anyone here is using RPi as a main PC? Seems to be capable of most office work with a bit of multimedia on the side. My laptop is dying and I would love to get something stationary that is low-power by default yet good enough so that the internet wouldn't lag. Mounted at the back of an LCD screen could make a nice wireless setup with the other peripherals.

I was using a Pi 400 for my programming PC, basically testing out if I can sell my gaming PC after I got my steam deck. It was perfectly capable for that task, and I’d say I would be happy to use it as my primary desktop PC.

Just sold my Pi 400 after the announcement of the Pi 5, deciding the Pi 5 will be my primary desktop PC. (Also ordered a Pi 4 because I have some other plans for it, but don’t want it built into a keyboard).

Falling back onto my Pi 3 I never really used before — it’s surprisingly capable. Not as a general desktop but gets my programming done fine. Its bottleneck seems to be I/O and limited RAM.

I have about 10 unused Raspberry Pis, so I collected unused monitors as well, and now run a mini code club in my local school. The school's laptops are all locked down to the point that running Python on them that this was the easiest way to provide a Python dev environment.

Why does everyone choose Python for that? Maybe a weird question for HN, but I still have no idea.

It doesn't require a person to change how they think about programming from their college C or Java classes, but is a lot simpler than those two languages.

You can have 4k60 and still have open office take seconds to respond to a keyboard input.

Sure but why include that if a text processor is too much for the board? To display static images or demoscene visualisations?

It will probably display video at those resolutions and refresh rates just fine, so it could be used for improvised commercial displays like a TV at a conference looping some information, for example.
