The addition of gigabit ethernet and USB 3.0 means that a Pi no longer feels like a bottleneck in one’s home network. I know that the Pi was invented as an educational product, but thanks to the Linux distribution OSMC it is commonly used as a media center for playing films, music, TV, etc. I have had gigabit internet for a few years now, and every day on average, I torrent a Blu-Ray image onto my main computer.

tl;dr they "built a gaming pc" with a "wireless anti static bracelet", RAM installed in single channel, backwards PSU, terrible parts choices... don't trust the verge.

I sold a company and the hardware wasn't included. I have a bunch sitting idle, plus about 1500 RFID tags and 20 readers. Takes up space but I can't get rid of. Should sell them.

i'm interested...

In which part? We only have a handful of pi's and half belong to my co-founder, he may want them. As for the RFID readers and RFID tags, we could definitely part with those.

Sure, if you're doing CPU-only tasks, Jetson Nano is A57 and Pi4 is A72 which is maybe twice as fast, but if you can offload anything to the GPU at all (media encoding, neural networks, matrix operations) you'll probably get some enormous gains in efficiency with the Nano.

OTOH, your going to be pretty much stuck with whatever handouts nvidia gives you unless your willing to hack the firmware/etc and reverse engineer stuff. Pretty much everything works on the existing rpi. Heck you can run Windows IoT on it. It has a UEFI firmware (edk2) port which mostly complete, and pretty much every distro and 3rd party OS supports it. And the hardware itself is mostly open at this point.

This. Jetson is part of NVIDIA's pipeline to drive customers to their chips. Raspberry Pi is vaguely that for Broadcom but is much more an end in and of itself. RPi is massively supported on the web.

If you're doing stuff that needs the Jetson, it's great, but the Pi is definitely better supported.

So on one hand, I get the excitement. This is a very popular platform that has a ton of community support and does a bunch of stuff. On the other hand, it isn't great at anything (besides the community - which shouldn't be underestimated, sure). It's also using a pretty proprietary chip - if you build a project off of a Pi, it's hard to migrate to a custom PCB. As a NAS, you probably would want ECC and a bunch of SAT…

I'm using mine as an X terminal. x2go is too slow (not enough CPU) on version 3, but vnc works.

How is that Hat $20 when the entire board itself is only $35?

I also balked at the PoE Hat and ended up going with a $10 PoE splitter (with USB out). Works with any Pi (until this RPi4 with USB-C).

Oooh I need to try this. Thanks for the idea!

That's silly. RasPis are stupidly useful. I've got: * A Zero W hooked up to a PM2.5 to do air quality monitoring in the house. Just bought a couple more sensors for it (VOC, eCO2, etc), but haven't hooked them up yet. * A 3B+ running the UniFi controller for my home network. * One is running a custom Hue automation I built to shift the color temperature of the lights throughout the day. * One is built into an interne…

> A Zero W hooked up to a PM2.5 to do air quality monitoring in the house. Just bought a couple more sensors for it (VOC, eCO2, etc), but haven't hooked them up yet. Do you have any resources on how to set up something like that?

Adafruit sells a lot of air quality sensors that can work with RasPi, Arduino, etc. They also have lots of guides. So I'd just go on there and take a look. My setup isn't really unique. I used this link: https://www.balena.io/blog/build-an-environment-and-air-qual... as my guide for setting up something with logging and graphing. I didn't do a full Docker-fied Balena cloud deal; I just replicated the stack manually and used their guide as inspiration. It's overkill, but was quick and works fine.

It was always the requirement. It was designed as a machine to replace the BBC micro. most PCs have BIOS, which is closed source, and difficult to get access to. yes there are opensource alternatives, but they are not entirely practical. Most modern PCs have a TPM, EFI and a whole host of other bits that make opensource drivers exceedingly difficult. Then there is the graphics card, where if you want to actually have…

Although PCs have traditionally had closed-source firmware, this firmware has not typically been used to implement malicious functionality (aside from cases such as the Thinkpad example above), making it historically less of a concern (though this is changing). Vendor lockin doesn't magically become acceptable because kids (nor is it ethical to teach kids that DRM is okay/normal). Also, define rpi clone - rpi did not…

> not typically been used to implement malicious functionality

so raspberry pi, in an effort to be more open than say Dell/HP, where you had/have to pay to download drivers, bios and other updates, is _more_ malicious than say apple/google who are competing to create a closed garden with a remote lockout, where nothing is owned, only rented?

ya.

I really don't understand this viewpoint.

Look, I've used embedded 386s. I've seen the evolution of ARM SBC first hand. I've used gumstix, sheevas and custom rolled jobbies. You know what united them all? they were bloody expensive and difficult to use. Pis are a joy to use. Plus if you accidentally blow the board, you're not down £500

Adding a DRM so that people can't make knock off cameras, in exchange for a £10 full linux SBC that is _easy_ is a worthy exchange. Even if they weren't a charity. The fact that they are single-handedly dragging the pathetic excuse for IT education in the UK ("here is how to use Microsoft office") into something approaching usefulness is a massive massive bonus.

The ecosystem that raspberry pi supports, the OS, magazines, training, teaching, class room outreach and research can only be done with cold hard cash. That cash comes from Pi sales.

Don't get me started on DRM. Look I know you think that everything should be free, but that means I can't earn a living.

Teaching kids that copy/pasting someone's work, making a halfarsed cheap copy and selling it for loads of profit, with no support is a good moral choice, you might want to re-asses your world view.

Yes open source is good. Yes you should give back and contribute. But, to move forward, money has to be invested, and it has to come from something.

Yes, removing ownership from the people is exceptionally bad. The trend towards the "sharing" economy undermines workers rights to the point that we are entering digital feudalism. But that is another topic.

Can you link it? Was the video streaming or playing from disk? Perhaps it was an unsupported video codec? There are certain circumstances where the pi may struggle to play video, but I think for common formats they graphics driver has hardware level support for decoding. If the video format was weird and it had to decode with the CPU it could see problems. Another issue is the power supply. If you do not use a quality 2A power supply, a little red light by the power jack will indicate reduced power and it will throttle the CPU. This applies to the older PIs, but I've not seen the Pi4 yet.

Can't wait to buy this, boot it up, play with it for four hours, then stick it in the same desk drawer with the other Pis I have bought over the years. (The upgrades look great, just my attention span is not so great)

So uh...what if I have no interest in home automation or possess a CNC or a 3D printer?

I just put together a Plex server with the RockPro64 4gb ram, PCI3x4 with 2 sata ports. I booted it up with Dietpi and things are running smooth! The board is a bit more expensive, but you can probably get it faster than the pi4 at the moment. The Dietpi community seems to be pretty great, any issues I ran into were answered pretty quickly

As to properly balance out this review, what exactly were the issues you had that needed to be answered by a community for the RockPro64? The RPi seems to have a slew of things that just work on it out of the box, and if there are issues, 99.9% of the time you can find the solution with a quick Google. Very curious to understand what type of issues something like the RockPro64 (which has appeared numerously in this thread as a 'great alternative') faces for anyone interested in the alternatives.
