Master Twig posted:I have a request for assistance involving a raspberry pi. Not sure if this is the right thread, but it seems my best option. My take, what you're describing is much more easily done with a webpage. You can pick up enough HTML and javascript in a couple days of beginner tutorials and have it working great. Then just use a laptop or even a Pi to display the page on the monitor. But the pi kinda sucks as a computer replacement for people that don't want to gently caress around with computers (i.e. people setting up an escape room). The microSD card storage is very easily corrupted if you don't take precautions to shutdown the pi gracefully. Getting it setup onto wifi and the internet is a big pain pulling out a mouse and keyboard. Compare to grabbing a junky old laptop and bing bong anyone is able to get it up and running instantly. Also writing a fullscreen GUI to take input and show images isn't trivial for a beginner to programming. Python would be a great choice but you're going to run into a bunch of rough edges and bad advice googling for "python GUI". You'll find decades old crap like Tcl/Tk, very confusing and professional stuff like Qt, and if you're lucky someone pointing you to SDL and PyGame (what you should use for this). But even using PyGame you're going to do so much more work vs. a simple webpage. You'll need to worry about loading assets (images, etc.), animations, handling input, etc. If you do this in HTML and javascript it can probably be 5 lines of code or less. Something in PyGame is going to be at least 100 lines. mod sassinator fucked around with this message at 19:42 on Apr 6, 2020 |

A monitor, a long HDMI cable, a long USB extension and a USB keypad would probably be best. Use mod sassinator's idea of making a webpage. Look up some javascript tutorials on countdown clocks and user input. Open up the webpage, press F11, and it's full screen and good to go.

Yeah, that seems WAY easier. I'm even finding a few HTML and Javascript countdown timers that are ready to go. I did get my Pi set up and running. Seems like it's running pretty well. OS boots up without any issue. I'm reading up on HTML and Java Countdown timers. Seems a lot easier to get that going, and to have the GUI that I want.

There was some discussion upthread about what to use an OG Pi 1 for. I just threw a fresh raspbian and raspotify on mine and it works splendidly as a Spotify Connect thingie, providing USB audio to my active speakers. CPU load sits right around 35% so it remains to be seen whether I’ll see glitches if the Pi decides to do some maintenance, but so far so good. I’m honestly amazed of how easy that whole thing went together. Only thing not plug and play was that I had to explicitly tell ALSA to use the USB sound card instead of the default.

Co-signed, I like volumio a lot overall. Mildly annoyed by their recent trend towards a more commercial offering with a subscription service / pushing tidal (lol). It's not obnoxious, but new features are starting to get put behind the subscription. But hey, people gotta eat. Also I don't like the new v3 UI, but that's because I have an old phone with a 720p screen. The one caution I'd have with Volumio: it has zero security, so it is unsuitable for anything but your own private home network. You can change the ssh password, but that breaks plugins. And it's impossible to permanently disable ssh (the on/off switch is on an unprotected webpage).

Windows assumes that all removable drives have a single partition and it does stupid things when that's not the case.

Windows also assumes that if it doesn't know what the partition format is, that it must be unformatted.

Disk Management in Windows10 allows you to fix SD card partitions (I say fix, i.e., flatten all existing partitions and make everything one big one). Question: What's the next step up from a raspberry pi that is more powerful and can use a 2.5" ssd? A NUC? Most NUCs are a bit of a big jump in price from a pi.

There are a few different fairly powerful system on a chip solutions out there. Beagle boards and BananaPi come to mind. Not sure how they play in the $ to power ratio though.

You can get used ultra-small form factor desktops for really cheap, or you can be like me and ebay a used i5 NUC for $140. At the point where you want good SSD performance, you likely want a full blown x86 computer, of which plain old corporate desktops will be cheapest.

I agree with Twerk, 5-8 year old corporate desktops or laptops are the best deal for a full pc. They are cheaper than a single board computer which could be considered the next step above something like an RPi. A thinkcentre tiny, HP/Dell SFF, or thinkpad might be a good choice. If you need GPIO or industrial bus support, the SBC might end up being a better deal

Hoping someone can help... I set up a Pi 3 a while back as a retro emulator and then repurposed it as a home automation controller (homeseer) so my knowledge of Linux is rather sparse. When I try to boot, I just get a rainbow screen. How do I troubleshoot this? At first I read that I might be able to change my config.txt file to include "boot_delay=1" and that might help, but I can't even modify the config file as the microSD is write-protected (I'm accessing it from windows since Linux won't start). I don't even know if that's the correct thing to do. I previously had my database for Homeseer corrupted, is the rainbow screen an indication that the SD card is hosed? I tried to run an analysis tool but it too got annoyed that the SD card seems to be write-protected...

I think if you get stuck at the rainbow screen, that means you aren't getting enough power. Edit: It's either the power supply isn't good enough or that the image on the SD card is borked.

Grab a second SD card and a USB SD card reader. Write a base Pi image to the new card and see if it boots. If so, put the original card into the USB reader and plug it into the Pi. Windows is flaky about the Linux formatted cards, but you should be able to run the tools on the Pi to check the card. I had one that kept killing some kind of allocation table, and running whatever the linux equivalent of CHKDSK was (fsck maybe? It's been a while) would make it bootable again.

I recall some talk earlier in the thread about how it's better to put everything onto a non-SD card... i'll probably just do that since the corrupted config earlier was a bit of a PITA. is best practice to use a thumb drive or something else? I have a tonne of USB drives kicking around so it'd be sort of annoying if I needed a a proper SSD! 16gb is really everything i need...

Thumb drives are very slow, an SD card would likely still be faster. If you have a Pi4 then you can get very good performance from a USB3 to SATA adapter like this one, due to the Pi4’s two USB3 ports. I have only used this with SSDs, a spinning drive would probably need more power. Edit: going by the docs the Pi4 still can’t boot directly from USB so you would likely still need a cheap SD card to boot from.

Progressive JPEG posted:Thumb drives are very slow, an SD card would likely still be faster. Alas, it's a 3B so I'm limited to USB 2.0 speeds. I think what I might try to do is get the log file(s) onto a thumb drive but keep the os/software working off a new SD card. That way the whole OS and software don't get borked when the SD card eventually fails. It's annoying because I really don't need more than like 2gb, so it's a lot of wasted money/space on an SSD... even though that seems like it would be the best solution.

If you write logs to a thumb drive you’ll kill it dead the same way you do the card. They’re not meant to take all day IO.

I just got a Pi4 this week to run Pi-Hole. It is in the "official" case, which has no vents/fans. Everything works great, better than expected, but I noticed that the web interface for Pi-Hole is showing that my temps are running between 62 and 65 C with a little "hot" icon next to it. Will this hurt in the long run? The only thing running on the device is the Pi-Hole software and it's managing my small home network of about 18 devices, so it shouldn't be working hard.

Pi4 is huge overkill to run pi-hole, I have it running responsively on a first gen pi B. The 4 runs hotter than previous models, if you throw heatsinks on it, it will probably calm down. The temp warnings baked into pi hole are almost certainly not accounting for pi 4 temps.

The Pi4 will protect itself by throttling the CPU at around 80°c. But if you're just running PiHole I doubt you'll ever see those temperatures. So I wouldn't bother with a fan.

Thanks guys. I got a deal on a Pi4 knowing it is overkill for Pi-Hole, but figured I could use it for something else in the future if I wanted. I'll just let it go for now, the temps are always in that range but never go higher than 65C. I have it sitting on an open bookshelf but the lovely case has no vents which is kind of weird. Had I known that before ordering the kit I would have bought a better case.

I don't think 65C is a problem for a Pi4, but I read about the temps being higher and got the FLIRC case for mine. It's made of aluminum and has good contact with the chip so it's a pretty effective heatsink.mewse posted:Pi4 is huge overkill to run pi-hole, I have it running responsively on a first gen pi B. Yeah, I'm using a 2B for pihole and it's basically just idling at <1%. It makes sense, it's not like DNS is a complicated service or like I have a lot of concurrent users in my house. I tried to think of something else to run on it but I already have a quad-core Xeon doing most of that stuff, I just didn't want to make DHCP+DNS reliant on my VM sandbox.
