Until my home automation got complex enough to justify a faster, more capable machine, I ran all my home automation stuff on an RPi. I use RPIs as "data collection" units. I have one RPi outside with a cheap SDR to pick up all the neighbor's weather stations, which I dump to a MQTT queue and use to populate weather data in my home. I use another to collect GOES satellite images. I have 3-4 RPis that act as "Digital H…

Why is ns2 in the garage? Everything you said makes sense except for that.

Geographical distribution. If the left half of my house is destroyed by natural disaster, I’ll still have a working name resolver on the other side!

Seriously, it’s just because I may do something else on that Pi that I want it on that side of the house. It’s my only garage Pi. My main internet handoff is in the garage, but my main “datacenter” is in a basement room on the other side of the house.

It’s all for fun. :)

> 1 CM4 as router running OpenWrt, to replace my ER-Lite. CM is the computer module, right? what kind of "board" do you use the CM4 with to use it as a router?

I went with Dfrobot [1] because they also sell a case (and it is all in stock). Had the CM4 already. I wouldn't have minded another one if I could've 3D printed the case but I didn't find such. Btw, I did have to go from 3 to 2 ports. Right now it is hooked up on my switch. I intend to put it between my desktop and my switch and run some iperf3. Because I'll get fiber soon, and I'd like to be able to saturate that. […

Thanks!!

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 Pi3 running pihole/dhcp for my home network, and 4 Pis as part of my home k3s cluster (along with 3 cheapo nucs). Yes it's overkill but I'm in infra and I learn a lot from it. The cluster runs nextcloud, collabora, plex, longhorn storage, deluge, nzbget, some custom projects I built to sync my bank accounts with my finance software and to sync photos from Signal chats to my nixplay frames, backups for my NAS…

Damn that is pretty impressive. I just drive my 3d printer and run the unifi controller interface with mine. Thanks for the inspiration.

> The accumulated inflation in the US since June 2019 is c. 17%.[1] This means US$ 55 in June 2019 is "worth" c. US$ 64.35 today. So it seems that you get a 4GB Raspi 5 for c. 7.25% less today. 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?

That my point: you can’t define how much a dollar is worth in dollars because it’s a circular definition.

You can, of course, calculate the change in price over time of a specific basket of goods (rent, steaks, corn). But there’s no reason this is connected in any way to the change in price of an entirely different basket of goods (Raspberry Pi’s).

In other words, if you try to define how much the value of a dollar has changed over time, you’ll get a different answer depending on the basket of goods you choose. So the change is clearly not inherent to the dollar.

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…

Thanks for the info! What system / DE do you intend on using? What type of work do you do on your computer?

I was thinking about getting a wireless keyboard+mice and attach RPi at the back of my monitor to have a clean and very low-power setup.

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.

Yeah, I'm not doubting that, and this is consistent with my own experience. But the claim was that it was specific to NVMe SSDs, which I find very odd.

Interesting. Did the earlier Raspberry Pi Broadcom SOCs not have an IOMMU? If they did I would have expected the 5 to be compatible with older ones.

I'm fairly sure that none of the earlier SoCs had an IOMMU. It's of course possible that there was one hidden in the GPU or something, but nothing on the CPU side.

What would be the benefit of having their own IOMMU instead of just using the ARM SMMU?

> 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.

Good luck doing "deployments" on SD drives and still have it run 6 months later, especially in environmentally unfriendly environments. Theses horrible little things die all the time, even when you buy supposedly high quality ones.

There are a lot of good reasons to not jump the gun on riscv. You're not going to get the same performance for the same price point on riscv at the moment. A lot of the existing software ecosystem still hasn't been ported over to riscv either.

There's no such thing as jumping the gun on RISC-V. If you're in the industry and not using RISC-V, you're already late relative to your peers. And you will be left behind should you drag. We will sadly have to watch it happen to Raspberry Pi 5.

risc-v isn't going to displace arm overnight. x86 still exists in the same markets it's always done well in despite over a decade of ARM trying to enter its markets. Raspberry Pi is doing the sane thing of delivering a good working product to its customers. It would have an interior product if it tried to do the same with risc-v.The fact there is no existing risc-v that comes close to competing with raspberry pi is evidence of this.
