You might want to keep the pi2 around after you decommission it. I read it's the best bang for the power consumption.

I'm throwing an old Pi 3 into service as a power monitor at a GFCI outlet in my crawlspace that nuisance trips so that I can get alerted immediately when it goes down. I figured I'd host a page, forward a high port, and use Uptime Robot to yell at me when the page is down. I intend this thing to serve a webpage and do nothing else. I don't want it to write at all if possible so that I can preserve the SD card. Based on https://raspberrypi.stackexchange.com/questions/109422/how-to-disable-logs, I've disabled rsyslog and configured journald to use only volatile storage. Is there anything else that I missed? What else should I do to make a Pi serve a static page for the next 10 years from my crawlspace?

Oh that reminds me. Anyone have suggestions on how to harden a Pi for more outdoor type operations? The Pi2 or whatever I have up in the attic is on its last legs and I’d like to get it replaced with something that can better handle being more or less in open but sheltered air. It gets pretty drat toasty up there and I can’t imagine the humidity is good for it either. Could just be the SD card dying though. IDK.

Like, putting a heatsink on the CPU chip won't really do anything because the CPU is almost certainly not the thing that's dying. If you have it in a fully enclosed case, you could change that out for something like the semi-open ones that are just 2 plexi sheets with posts between. That way it will stay at ambient temp at least, rather than heating itself even more. Humidity is probably not an issue unless your attic is growing mold or poo poo. But yeah, swapping SD card and power supply is what I'd do first.

Has anyone had any luck with cheap aliexpress power supplies for pi 3 that don't trigger the low voltage thing? I got two with push button power switches and they both do the low voltage thing, super frustrating

A pi-specific power supply will supply a bit more than 5v, usually 5.1v, to account for variances in cable quality. A 5.1v power supply is a good indication that it was built with the raspberry pi in mind. You can try switching out the cables for something thicker or better quality. Also, if you only occasionally get the low voltage warning, you can try using a governor that doesn't change power consumption, like powersave or performance.

If you have a PoE switch there are some inexpensive ethernet/usb-c splitters that work pretty good. the basic 5V/2.4A ones seem to work fine for our pretty basic needs (just a UART relay really)

I've got a pi4 that I use for streaming stuff from my pc to the telly but I'm wondering if there's any way to get it to stream from disney+ because there's no app for that on our smart tv. I have chromium media edition but when we tried that it ran like poo poo and I assume I've hosed the configuration up somehow and should just start over - is raspbian + chromium the best option for that or should I try a different os? The pi is on a wired connection (and can stream 4k video from the pc) and disney+ works fine on other devices in the house so I don't think it's a bandwidth issue but any advice is helpful at this point.

Consider getting a Chromecast with Google TV to replace the function of the Pi. There's a VLC app you can install on it to handle streaming from your own sources, plus you can stream Disney+ either from your phone to it or use the standalone app.

Yeah Disney very much doesn’t want you to be able to access their videos as video files and hand them around your network. They keep it all tied to apps. So you need some kind of set top box. Kodi is the software for that and there’s an add on for Disney that you could try. https://www.technadu.com/disney-plus-kodi-addon/223344/

This is kind of out of control, but I don't think there's any cheaper way to get a capable SBC in Canada in 2023, is there?  The $26 for s&h on a $300 order made me lol. Not sure if I want to pull the trigger on this because that is a lot of money for not very much computer.

I'm thinkin about when we have a setup that is reasonably all close together instead of a bunch of pis just having a server running docker instances or whatever. It's all just UART to ethernet mostly anyway. Everyone is comfortable with the Pis though so probably will be a tough sell. They're also fine with just connecting pis to PDUs that toggle the power off and on on command despite my repeated warnings to not loving do that (multiple SD cards have been corrupted at this point). Apparently logging in and typing "sudo reboot" is too much of a hassle.

I think the power requirement is the main thing I need. I just want a little box that I can plug a battery bank into and control an old DSLR to take timelapses of poo poo. I guess specifically it's to replace the pi zero w I just bought for a chicken coop surveillance camera thing. The old zero just doesn't have the power to drive the cameras at a useful framerate for motion detection. But I found out about the libre board stuff and ordered one of the Le Potatoes (https://a.co/d/5LC6B08) to see how it goes!

I think as a rule of thumb, unless your project uses the GPIO, the Pi is probably the wrong solution. There's so many better and cheaper ways to do things like stream media to a Chromecast or run home server stuff in a container on your NAS or even your router. My ancient RT-N66U can run a PiHole equivalent and it still gets regular (community) patches.

Like for home server stuff I already have one of those “thin client” x86 office surplus hp’s, for NAS I have a synology. I don’t really need GPIO for my other little smart device tasks except very rarely, but I actually don’t know what other options there are for a <60 (hell, I’d settle for <$100CAD) low-powered ARM computers. Edit: oops, I just remembered hackerboards.com

I was running tomato on mine for a while but kept having issues and swapped back to the default firmware. Seems like every time I buy a router, it's the wrong one and the most popular alternative firmwares barely support them.
