If you're going to run a whole rear end PC server anyway why bother with RPis for server duty at all? Just set up some VMs or containers.

I motivate everyone to start buying power squids instead of traditional power strips, technically it's more wire but you get to use 100% of your outlets which is a huge upside.

The problem I'm seeing is because of the amount of juice flowing through the box, it's pretty hard to find bricks that charge more than two devices. Or they throttle pretty badly once multiple devices are plugged in. And all the options out there right now are just as bad for blocking outlets. There's still a density advantage if it has two or more usb ports, but still. Nothing has been learned.

I just set up a Pi Zero W in a headless setup where its only going to be on some of the time (serving files via SMB 1 to some old hardware via a USB Ethernet adapter isolated from the internet) and currently my only problem is figuring out how to turn it off. Currently, I'm ssh-ing into it over wifi to shut it down, but I'd ideally like to get some kind of physical button to use for safely shutting it down, is there anything I can get for that that's simple to set up?

You can hook up a power switch. There's some hats that have them built in https://howchoo.com/g/mwnlytk3zmm/how-to-add-a-power-button-to-your-raspberry-pi

Soldering at this level is not too hard, I suck at it and I can still do it, and basic tools are not super expensive. That said there are pogo pin rigs for being able to connect a hat without soldering, but you'd need a PCB in hat format that then broke out the right GPIO pins for you to plug in a button.

There's not much to go wrong with a heating element with a handle screwed to a chunk of metal.

If you don't know how to tin the tip properly, it will eventually get too oxidized to do much of anything. The first weller I got that I didn't know how to take care of eventually couldn't melt solder at all because it got too oxidized.

That's what got me to switch from a MySQL shared database Kodi setup to Plex in the first place and what keeps me from trying Jellyfin. Every hotel or AirBnB I've stayed in, every friend or family member I've crashed with, no matter what kind of setup they had if there was any connection between the internet and the TV there was a Plex client available somewhere.

I've never had a cheapo iron outright break on me, even while learning. However my soldering vastly improved once I got a Hakko FX-888D because I had gotten to the point where I was good enough at soldering that the low power output and temperature control of the cheapo iron was holding me back.

You can get a soldering station with temperature control for like $30 on Amazon. Or spend like $75 for a TS100 with a power supply. Don't try to solder with a crappy $10 iron without temperature control. Use leaded solder (not lead free). If the solder comes on a green spool it will be trickier to work with. Get some flux. And some rubbing alcohol and an old tooth brush to clean with.

Super-cheap irons that don't have temperature control suck for soldering directly to a circuit board. They're both underpowered (low watts so they don't cook themselves) and will get too hot (a 25W iron will go over 400C, eventually). It works but there are a lot of downsides, and it's totally possible to gently caress up your board as a beginner. If the iron is too hot your can destroy components. And being underpowered means you can easily keep the iron on the board too long as the heat gets sucked out. If you're gonna solder electronics stuff you really want temperature control. It's doesn't have to be a fancy digital one, but the old crap from the radio shack solder kit is just a really bad idea for doing PCB work. Trust me. I also had an old cheapo 25W iron that I said "good enough, I hardly ever use it". hosed up a trace on the board, learned the hard way. (Trying to fix something that was already dead so not a great tragedy, but still.)

loving up traces just teaches you how to use a bit of wire to create a new route around the damage! Free education! I was told in the distance past that this is called field wiring, but looking it up now I'm not sure anyone actually uses that term.

I prefer lead-free personally and dont really find either easier to work with than the other. if you want a power switch for a Rpi you can get in-line lamp switch USB power cables and use that?

I recently got a zero 2, a fresh install of rasbian and This 800x480 screen connected via HDMI cable. It only wants to display in portrait, the options to rotate are greyed out unless I lower the screen resolution which then causes the screen to go purple (I'm guessing because the resolution is too low)  The manufacture pages act as if there shouldn't be an issue with rotating the display and nobody else seems to have mentioned the issue so am I missing something obvious?

Admittedly I'd glazed over the setup bits thinking it was just to do with the touch screen. Whilst looking into trying to alter the config file my pi asked if I wanted to do updates and suddenly I could rotate the screen.

I bought the Pi4 Canakit that has been collecting some dust. Think it's try to give this emulator thingy a go. Is there a good guide out there that uses (or assumes) you have everything in the starter kit? Google is all over the place.

Is there a good guide out there that uses (or assumes) you have everything in the starter kit? Google is all over the place. There's not much to it. Download the official Raspberry Pi imager tool and flash your SD card with your chosen image. IIRC the imager tool has RetroPie and Recalbox options built in. Pressing Ctrl-Shift-X while the official imager is open will open a menu with wifi credentials and locale settings, both of which are much easier to enter here than on the software itself. Another popular choice is Batocera. You can find an image file for it here. Write it using Balena etcher. These all do essentially the same thing in the same way, using a front end called Emulation station to run RetroArch, so it's really a choice between what kind of customization options they offer. It might be a good idea to just flash each one and play with them for a minute before you get the SD card loaded up with ROMs. I use RetroPie. It has good documentation including a getting started guide here. I'm sure the other distros have something similar if you search em. Whatever image you use, you should play around with the options and get it set up before you move your entire ROM library onto it - I hosed up and had to reflash a few times, which would have been much easier to do if I hadn't been loading them up each time. loopsheloop fucked around with this message at 13:56 on Jan 27, 2022 |

A few weeks ago I stumbled onto the page and slapped it on my 4GB Pi 4 after hearing aarch64 was a minor performance bump versus 32-bit. The only thing that seemed amiss was that the first apt-update triggered some weird circular dependency with VLC that was resolved by apt-removing and reinstalling. Other than that it’s been smooth - compiled Vulkan and a few Quake ports, installed Firefox ESR, and generally found it to be perfectly fine. Edit: though come to think of it, video acceleration also seems iffy. I need to spend some time digging into that. Hasturtium fucked around with this message at 21:08 on Feb 2, 2022 |
