I run a Pi Hifi server myself, it's plugged into my DAC/amp. I hope you intend to do something similar - ie, use the Pi to decode stored digital music at a high quality (due to proper drivers + bitperfect audio stream) and send that stream to a dedicated DAC, rather than using the Pi itself as analogue out as well. That would sound shit for a variety of reasons.

Is there a legitimate reason other than dire lack of experience (and hence necessity for handholding and explicitly tailored support) to get a genuine Pi rather than one of the many alternative boards?
Assuming a non-shit board, of course, meaning at a minimum can run debian/raspbian + has good driver support for everything.

>> No.67806924

>>67806896
Depends what you wanna do, but most likely the 3B+. Have an idea of what you wanna do with it before buying it though. Here are some recs:

Ok, things you can do with a Raspberry Pi:
Hifi audio server for bitperfect playback, without any mechanical noise from hard disk spins or fans. Look into Volumio for a prepackaged distro, or 24bit96.com for how to build it yourself from scratch.
Turn it into a docker server to store files and generally learn how both docker and networking work, always a useful skill.
Set up a personal internet facing server to learn security, have it host files or be a mail server as well
Install Pihole and have a network-wide adblocker that speeds up browsing
Turn it into a Tor exit node and/or a bridge for Tor connections to both learn how Tor works and secure yourself to a higher degree.
Use it as an IRC bot, or any kind of bot for that matter.
Turn it into a seedbox to always be seeding torrents for private trackers.
Plug in a camera and hide it somewhere for security (or to spy on roasties)
Hide it in a public place and scan for handshakes on wifi networks.
Use it as a general playground for new shit like distros (arch, gentoo) or possible alterations to distros you want to test run before applying to a more important device, if you lack a laptop for that already.

Honestly, getting ideas for what to do with the Pi come easy after you get into Linux.

But you lose out on onboard wifi and bluetooth.

Costs the same as a 3B too, and has surprisingly good software compatibility including better OpenBSD support than the Pi due to less issues with proprietary blobs (and of course full debian/raspbian/dietpi support).

A significant proportion of alternative boards specifically implement a Pi-compatible GPIO header so more often than not that's not an issue.
You do get much lower quality support if you buy a chink board nobody uses, though. That said I've seen some boards have pretty nice and helpful communities when I checked.

>> No.67807031

>>67807003
A 3B+ will do that for sure. A Pi1 could do that even. I'd expect a Pi0 with GPIO pins could flash a laptop too, I just use a USB programmer which doesn't look like it has too much processing power on it. I would get the 3B+ though as the 0 is very under powered, and without an ethernet port wouldn't make a useful pihole.

WTF is up with pifags? You could have just bought a sansa clip and gotten superior sound and superior everything without downloading linux or another bloated OS, and you wouldn't have even needed a DAC.

Its like you guys like to do everything as inefficiently as possible, downloading this-does-everything-but-shittily software instead of getting a real music player or using a netbook you already have instead of falling for more jewish tricks to buy more hardware you will never use.

You are like arduinofags but use heavier software, have to add an SD card to you 'real computer' and waste more money on crappy hardware and software when superior versions exist that even cost less.

ESP8266 is all I need to deauth wifi and control my lights. If you are using a pi, chances are that your solution is inferior to a cheaper and better running solution. With the amount of old parts you guys still have left, 99% of people who buy this are retards who will just have it collect dust.

PSP > Pi for gaming and cheaper
Sansa clip > Pi for music
Netbook > Pi for portable computing

And they're all cheaper. The only thing its good for is removing ME, but I'm almost even an arduino can do that.

Every flash based DAC already has that, Distro for audio files? LOL

Or just add a hosts file to your hopefully DDWRT/tomato, unless you were too cucked to get one that can be flashed

I don't need pedo software that often, and TOR is compromised long ago

Yeah buy the $30 camera or the $6 camera that looks like ass and is xboxhueg, nobody will see it

>Hide it in a public place and scan for handshakes on wifi networks.

ESP8266 can do that and use less power

>Use it as a general playground for new shit like distros (arch, gentoo) or possible alterations to distros you want to test run before applying to a more important device, if you lack a laptop for that already.

If a distro exists for it.

You got two options. You either build your own following the guide on this site: http://24bit96.com/

it's pretty niche, I have two old garage doors that also have outputs that tell if they are open, kinda cool to open/close both and monitor both with the GPIO and all wifi.

Might do that pi-cade thing where you get a nice joystick and build the pi emulator right inside...

Carputer makes sense too, afraid someone would just steal a tablet if it put it in car. (plus OBD stuff would be nice)

I bought 2x for $40, I got it off craigslist. UMD didnt work lol. Even at $60 its still a better buy since the pi is just one component. Just add a charger and adapter with mSD.

For an rPi to be usable:

>needs display
>needs power supply/battery
>needs controller/keyboard
>needs case and all 3 if portable, plus shit ton of time

The only thing its got going for it is N64, which the PSP can also do (but much less)

>>67807251
ESP8266 will do it cheaper, less power, and doesn't need OS since its embedded. Also much faster GPIO

Or you can just get a nice controller and attach it to a netbook with a CRT with VGA. Better performance too.

Carputer doesn't make sense. Touchscreens in cars? THEY SUCK. The OBD2 you can simply use a device like your phone or leave one in there since a lot of them have bluetooth or wifi if they're wireless. Not expensive either. https://www.aliexpress.com/item/2014-New-Release-Super-Mini-ELM327-Bluetooth-OBD-II-OBD-with-Power-Switch-ELM-327-OBD2/1611613475.html

You need relays if you are putting it into your walls. If you want to control lights wireless you don't need it unless you're modding the device and not the actual plugs.

why don't you just learn how to do something useful like installing gentoo/clover, maybe even with the rPi?

I'm convinced that rPi has cool capabilities nobody uses, kinda like smartwatches aside from the pebble. Its designed to extract money from you via sensors and hardware, like a loss leader (why the cases are overpriced). And sadly its so big that everything it can do, everything that can do it better is smaller. Its just reselling useless parts that nobody wants, parts that are too big and technologically weaker but not useless, only now they mark it up, sell it to you to buy the next version that does nothing better.

Its like buying a desktop, only laptops with all components such as monitor and input are cheaper and have even newer hardware and run more software (speaking of used smartphones of course). Plus you never used the first desktop in the first place. Aside from GPIO, which arduino can do faster and use less power, its not better than anything out there.

I bought a pi 3 b+ a few weeks ago and ran it off a wall adapter. Nothing showed on my screen so I took the micro sd out to change the config. Put it back in the pi, still nothing. The sd was fried after that and won't show up at all on any machine.

Is the pi fussy with power supplies? I don't think the wall charger I have is the best - it pulsates if i switch it off which is fucked up when you think about it - for something like the pi anyway.

Pi 3B+ with my emulator and compiled CHIP-8 games
64x32 LED Matrix (either from adafruit if I'm lazy or those ali sites)
4x4 Matrix keyboard

Then sometime after:
Something to emit a buzz or beep sound for its 1 sound beep capability

And of course, all the bits I need to connect all of these together
