Where do you buy an Orange Pi? When I was researching these devices I found it to be extremely weird/sketchy. These are three different websites all apparently from different companies: - https://orangepi.com/ - https://orangepi.net/ - http://www.orangepi.org (note: https does not work)

First two links are resellers, as mentioned in the footers. But yes, Orange Pis have always been a bit shady.

So the third link is the official one? Its footer has some very sketchy looking links, including to two different telegram channels, three aliexpress stores, and some guy's skype username...

Then again, we might not even be seeing the same site, since it forces http:// and could be modified in transit by anyone on the path of either of our ISPs and the web host.

The Pi 5 looks neat and I hear it's finally got a power button built-in, which was always the sorest point of the rpi series for me - the fact that it had no good story for safely idling was always absurd. The default configuration was "if you lose power there's a good chance the filesystem will be corrupt". Still, does the new one do better beyond having an off-button? Like does it wake via USB properly? Does it hav…

Power button was just a pair of wires to a switch and some settings in old rpi IIRC > Does it have some way to safely recover the filesystem after power-loss? that is not a hardware feature

When they have a recommended OS with their brand name on it (Raspbian/Raspberry Pi OS), it's a platform feature. Either I'd expect the hardware to provide some minimal battery or something for safe shutdown, or I'd expect the software to handle sudden power-loss gracefully. They provide both the hardware and the software, there's no way for blame to leave their ecosystem.

Raspberry Pi can't redirect blame for filesystem problems if the user is using an OS that's called "Raspberry Pi Operating System".

Ebay or Aliexpress are good options with buyer's protection. I bought quite a few OrangePis in my time, although that was at a time when the Orange Pi Zero was 9 EUR a piece. At current prices, I don't see the point.

The OPis themselves were quite decent devices, Raspbian worked very well on them.

I like this idea, but what do you do for GPIO (and SPI, I2C etc.)?

Arduino or similar over USB.

This is, in almost every respect, the better way.

Any non-real-time operating system will eventually get a little bit buggy around timing intensive operations like I2C or (especially) SPI. Better to have your GPIO operations performed by a dedicated micro that only handles your serial traffic and whatever pin-twiddling operations you need to do. Ideally, your serial traffic is in a binary protocol like MODBUS-RTU, so your traffic parser is as fast as possible.

Bitbanging I2C or SPI is tedious but generally pretty achievable in a bare-metal application. But unless you're hacking your kernel to force that kind of timing fidelity, bit banging on an RPi running Debian is just impossible.

Geez for the prices listed in the article (153 EUR and 301 EUR), get a TMM (tiny mini micro - https://www.servethehome.com/introducing-project-tinyminimic... ) computer. These are the SFF/USFF off-lease older enterprise computers like Dell Optiplex. Note that ServeTheHome.com does power consumption for every model it reviews. These ~1L sized computers idle in the 7-13W range. Even with EU electricity prices, it would…

I do similar but I look for older laptops.

Gets me integrated: battery, screen, keyboard, mouse

I can buy an old laptop for $100 and would cost me $150 for similar RPI hardware.

Hm...

The 65W power adapter on Dell retails for $46.99 on sale, bringing the grand total to $156.99.

And that's just after skimming your link for 2 minutes.

FWIW once I started deploying my Pis with automotive-grade SD cards bought from Arrow and Canakit 5.1v PSUs, all the stability & integrity issues completely disappeared. Costs a bit more, bringing the price of a setup closer to a used SFF HP or whatever, but it’s super stable. Whether we should feel bound to go to such lengths is another topic…

Yeah, that's what kills me with rpis. Yes they're cheap... until you add a chassis, a safe SD card, a 1st party power supply that won't give you the dreaded voltage warning icon, etc.

I don't regret owning some since they basically taught me to do Linux adminning, but the shopping experience is a bit like buying an airline ticket.

What’s the power consumption on that? The biggest draw for these machines (to me at least), is how they seem to run on a 5w power source.

You might be able to run on a 5W supply, but my experience is that booting on a less than 15W supply is a recipe for corrupted SD cards and hard-to-trace bugs. My biggest frustration with hobbyist boards is how little power the can source to e.g. the USB ports. Its super frustrating to need a powered USB hub to add e.g. a USB indicator light. The fact that you can power the RPi from the powered USB hub seems hacky, b…

I sure wish I could get my Pi 4 to boot with a powered USB hub attached.

After trying three I gave up.

Am I crazy, or are we jumping from 4 to 5 whilst ignoring the fact that most of us still can't get hold of 4 due to the supply chain issues?

there hasn't been a shortage for a while now, but you probably didn't hear about it because shortages ending isn't considered newsworthy.

it's the same with sriracha, you can pretty easily find it for msrp now, but lots of people still think it is hard to find because the last thing they heard on the topic was a news article about bottles selling on the gray market for $40-$80 back in may.
