I'm okay with debian and looking to get one and set it up for my father to use as a PC. It's going to be awful for video editing because of the limited data bandwidth and slow poo poo GPU. That stuff will also be bad for image editing if we're talking 10 megapixel plus photos. You should probably pick him up a couple years old laptop and stick it on a cooling pad, with a monitor and keyboard/mouse running to it - they'll be around $150-$200 for a nice Sandy Bridge system from 2011 which handle all of that flawlessly. Here's a good example, the case is beat up but who cares? It's not going to be moving: http://www.ebay.com/itm/Lenovo-Thin...tEAAOSwYlJW2HmX

maltesh posted:I don't have a Raspberry Pi: I do have one of those CHIP $9 computers, but I suspect the answer would be the same for this, too. I was able to run an old Raspberry Pi (original model B) that way, but it had a bad habit of dropping USB connections which was a pain. When I switched to powering off a separate power supply, the USB unreliability went away. Can't say if the same thing will happen with the CHIP, but you're probably better off just using an old cell phone charger for the device's power supply and plugging all the usb devices into the the powered usb hub, and the hub into the device.

PBCrunch posted:So is there any chance the next Pi revision could get USB 3.0 (or 3.1)? That seems like it would solve a lot of the RasPi's problems. It would be great if they could upgrade from USB 2.0 to 3.0 and figure out some way to boot from something other than FAT32 partitions on slow, unreliable microSD cards. It is more likely that they split the ethernet stuff off of the single USB bus first (and finally upgrade the GPU...), since that's what other similar cards do. None of the cheap mini-computers like this seem to implement USB 3.0, although if you need it you can go to ~$100 tier devices it seems.

Touchscreen support can always fall back to only recognizing a single touch input and detecting it as mouse positioning and clicks. This can get weird with multiplefingers touching at once, but usually sticks with the first finger to hit as the cursor location. Depending on precise drivers, you can switch between detecting multiple finger as multiple buttons (like say, 1 finger left clicks, 2 fingers right clicks) or straight up recognizing gestures from multiple fingers.

mod sassinator posted:In a pinch it could run it but it's going to be really slow with just a single core 700mhz CPU and 512mb of ram. Think back to how slow computers were in the early 2000's (Pentium 3 700mhz or so) and that's what you can expect with the Pi Zero. For desktop use and multitasking you really want a Pi 3 with faster cores and more memory. Besides you're going to want to hook up networking, a mouse, and a keyboard so you're going to need to buy $30 in accessories to connect all those components to the Zero vs. the Pi 3 has networking built in and plenty of USB ports with no USB OTG adapter needed. You're off by quite a ways. The 700 MHz ARM CPU in the Raspberry Pi Zero is more on par with like a 300 MHz Pentium II computer from about 1997, albeit with more RAM then you'd have then. It remains true that the Pi 2 or 3 will be a lot more pleasant of course.

Police Automaton posted:An old Atom might even be better for some Linux usage scenarios even if consuming a bit more energy. The single core Pis aren't really good general purpose computers, except if you run them with RiscOS. No matter how accurate the comparison with the PII is (I find comparing so vastly different things in real life circumstances a bit more difficult than that) the PII will feel snappier with 90s era software than the Zero will ever feel with current era Linux software, that's for sure. Well yeah, "but it has to run modern software" is implied. The most directly accurate comparison is that the Pi 1 and Pi Zero are the CPU and GPU of 2005 or 2006 smartphone with a video codec handler bolted in to make video playback better, but a lot of people never touched smartphones that old, let alone had experience using them with a normal size screen. Hence doing the rougher comparisons to desktops that people might have used - they really do benchmark at about the same as the stated computers, and don't have the benefit later revs do of having multicore which can help some things severely.

Tigren posted:This is my problem too. I built a loving full size arcade cabinet and the hardest part is figuring out which version of which games will actually work on this stupid thing. The MAME scene is such a total mess. I should have known getting into retro game archiving communities would lead me down a very dark hole. Abu Dave posted:The fact that the stupid thing can run Tony Hawk Pro Skate 2 at 60 FPS fine but can't run street fighter 2 arcade baffles my mind Here's a big explanation of why emulation is inconsistent on the Raspberry Pis: First off, MAME since many years back has focused on as near to perfect hardware cycle accuracy as possible. This means the games require much higher processing power for the emulation machine than they did in either the original versions of MAME (which allowed all sorts of hacks to get speed at the cost of accuracy) or most typical home system emulation (which are also fond of allowing hacks to get fast speeds at the cost of accuracy). Now this approach actually works great for getting games to run, because it means if you get X chip that was used in like 500 games perfectly emulated, the work put into getting that one chip running perfectly means all 500 games have that part handled in one fell swoop, rather than the old system where you'd gently caress around and do 500 special cases of emulation, one for each game. And the Pi 1 is slow as poo poo. The Pi 2 and Pi 3 ultimately aren't that much better, compared to a normal desktop or laptop from even like 9 years ago. So, the MAME builds available for the Pi tend to either be a fork from early MAME builds before they went all-in on cycle accurate (making them fast but with a lot of missing compatibility) or forks from more recent builds (very high compatibility, but easily runs slow as balls). So you end up having to make a trade-off between the two, and usually the most popular option is inaccurate, fast, but low compatibility builds. The reason you still get reasonable speed PS1 emulation and for things below that on the console side? Those have pretty much always gone for "be inaccurate if necessary to be fast". Many of them aimed to handle the performance of the target console on computers from not long after the consoles came out, so computers in the late 90s, and that's around where the Pi 1's performance sits, with Pi 2 and Pi 3 bumping up past that (although still with the same GPUs). Also, quite frankly, console designs were simpler to program for and simpler to emulate than the many crazy tings done in arcades. so anyway if you're really going to build a full size arcade cabinet, respect yourself and get one of those cheapy NUCs or similar x86-64 devices and modern integrated or discrete graphics chipset. it will run MAME way the gently caress better than the Pi will, and be way more compatible.

Police Automaton posted:I have no idea how the Pi got so popular for emulation. It's small, it's cheap, and the requirements for average emulators for like all the consoles before the PSX/Saturn/N64 era are satisfied by it. It's easily on par or better, performancewise, as the many things like the Dingoo A320, GP2X and other such handheld devices that were supposed to be game systems int heir own right but everyone knew were meant 100% for emulating old game systems. It just starts to fall over when you want to get beyond that, or really play a lot of arcade games.

Hopefully, they'll finally update the GPU component in the Pi 4? You can play like Super Mario 64 or some early PSX game fine though.

Hadlock posted:There's not a huge incentive to upgrade the GPU, the Pi will push a 1080p screen all day long, which is the main use case for it. 4K screen adoption rate is low, and probably even lower in public schools. If massively parallel computing computer science becomes a thing in the K-8 world they might have some incentive to upgrade it. An improved GPU means it's far more useful because far more things can run on it all, or run on it better. Or hell, it can even be used primarily for teaching basic small-scale general purpose GPU coding stuff. And no, it can't really push a 1080p screen all day long acceptably in a lot of use cases, the GPU just isn't powerful enough because it's a design originally intended for 640x480 smartphone screens of 10 years ago, slightly upclocked in the 3 model.

Foxtrot_13 posted:The thing is the Pi isn't poorly performing for the use case it was built for. It is a basic computer for basic computing tasks on the cheap for the education market and it does that in spades. The cases for a better graphics chip or better USB/Lan throughput are not for the education market. Have you not used a school computer since 1997 or something? There's nothing about "educational" that requires that the GPU be horrible. Nobody's asking for the latest GTX whatever they're up to now to be in there, but just to move the GPU tech forward about the same number of years that the Pi 3 CPU is compared to the Pi 1. The constraints were more than acceptable 4 years ago because they were absolutely necessary to bring in the low cost factor. they're really not acceptable now, especially since let's face it a ton of the sales are not for "education" they're for other niches which subsidize the education part of their goal.

doctorfrog posted:Going by what little I know about the education system, the cheaper the product, the more willing the school. I honestly don't know: is the Raspberry Pi Foundation deliberately and stupidly picking lovely parts, when they could build a significantly better system at the exact same price point and not a buck more? They've somehow managed to upgrade the CPU twice and mildly overclock the GPU once in the past 4 years. What makes you think that getting a new GPU would magically skyrocket the cost? What makes you think moving off a USB 2.0 bus for both storage and network would skyrocket the cost? I'm going to be blunt: schools barely use the drat thing. Schools primarily use full on x86 and these days x86-64 computers that cost easily 10x as much as a Pi. I get that the gimmick of the project is that it's supposed to be for the schools but it's never been something particularly useful for a school unless they're specifically after GPIO applications - which most schools never touch. Hell the "low" price often gets outweighed by the costs of input devices, displays etc - and don't forget a case so little Timmy doesn't spill his lunch on it. But it's not like it's less useful to schools if bottlenecks are removed in the Pi 4!

If instead they switch to a SoC with eg a Mali GPU then we go from having a documented GPU with the potential for fully open-source drivers for everything to one that is not documented and can only be accessed via a binary blob. I'm not sure why this is unclear. But that is again irrelevant, because by using the SoC for years before any large scale public documentation was out, the Pi foundation indicated they don't require public documentation to use an SoC. And you still need a bunch of binary blobs even with all this documentation for this chipset, so it's not even providing the benefit you seem to think they're relying on.

You may need to fiddle with the settings for the NES and SNES emulators - but expect games for the SNES that used a lot of expansion chips (Like Star Fox, the later Megaman X games, etc) to be slow regardless.

Police Automaton posted:Somewhere on the fan there should be a print how many amps it needs, if not then what voltage it is and how many watts it consumes. Then you would only have to calculate Watts / Voltage to get the amps. USB 2.0 is specced for 0.5 Amps or 500 mA maximum at 5V, although the Pi can apparently supply past that on it's ports. No idea what the Pi's GPIO header is specced to deliver at maximum but you can probably google it easily. If it's a very small fan it's probably a 5V fan to begin with, there's a good chance a 12V fan won't be able to start with 5V. (although some can) There's nothing printed on the fan, but It's from this kit: http://www.eeekit.com/3in1-starter-kit-for-raspberry-pi-3-model-b-board/ which claims the fan is 5V 0.2 amp. so that should be fine?
