I've bought from Newark Element 14 and resellers on Amazon (sold with amazon prime etc). The one from Element 14 died within two weeks somehow and I was able to send it back for a full refund (they sent me a shipping label). The one from Amazon got crushed in shipping and was also covered by them (with a shipping label) and they sent me another. The main difference for me was that Amazon shipped more quickly but didn't package it as well.

Zuph posted:MCM Electronics almost always has them in stock: http://www.mcmelectronics.com/ Ordered my Pi, a case, and some assorted cables for a project from MCM. Picked them up the same day (cause I live 20 minutes away. Envy me.). The initial backlog of orders is over now, manufacturing is pretty steady, and most places have no problem keeping them in stock. Even if a retailer does run out, the wait is at most, a couple weeks, not a couple months like it was when they were first released.

I'm fortunate to have a spiritual successor to CompUSA near and they had all sorts of versions of it. Good stuff. Got the basic with the case and the AC adapter. Now to actually get Emulationstation to work properly on it, I'd be golden. Speaking of that...and forgive me if this strays to far into FILEZ territory, but does anyone have any good web resources on getting NES emulation to work. I'd like a multi emulator as an optimal option (NES, SNES, GEn, TG16 and MAME..basically my childhood.) but just getting one to work would be nice..

NES emulators? They're simple, just run the program and load the ROM. Unlike many later systems, there's no need to hunt down and apply BIOS dumps or complicated controller mappings.

If you use a raspi and do a lot of SD-swapping you will have noticed the SD reader is really crapy and breaks easily. I'm quite clumsy so I managed to break one of my rapsberries this way. After some googling, I found a suitable replacement for the builtin plastic one and tried to replace it. Of course, I managed to burn a pad and part of a track when I desoldered the broken piece, and ended soldering the new one in all but that broken pad (which happens to be one of the two which are used to sense the presence of a card in the SD reader). Now I just need to short that track with its neighbour (so the raspi will think there is ALWAYS a card, which is acceptable), but of course i'd need to somehow repair the broken track, at least to expose it so I can do the short. Anyone around has experience fixing this sort of things? Is it posible to fix anyway? I have found references about a "PCB track repairing" pen, but it costs more than a new R-pi...

If any of the track is left on the non-burnt side, scrape the solder mask (the green stuff) off the copper and solder some 30 gauge wire from there to the SD card pin. This is a bit tricky, but cheap.

Do you have a link or part number for the SD card slot you used? I broke a pin on one of my Pi's SD card readers and haven't gotten around to finding an exact replacement. I wish they would just throw an extra dollar on the price of the Pi and use a quality card slot in the first place. Mine broke the very first time I inserted a card--luckily I can still make it work if if put a little pressure on it, but I dunno how long that will last.

Instead of inserting and removing sd cards you should use a microsd card and just leave the adapter plugged in all the time. Its no big deal if the adapter wears out.

Setting up a RetroPie was painless (though I am a CS PhD student). A quick dd of the image, popped it in my Pi, raspi-config to expand the filesystem, set up a shortcut for quitting out of emulators with the USB controllers I got, and I was good to go. e: Ezrem posted:I'm trying to set up the piface web interface that is included in pifacedigitalio.

I didn't see anything about dependencies in the documentation. Which version of Python are you using? Looking at the code, it's using the http.server module which (I believe) is python3 (refactored from python2 with SimpleHTTPServer). Or, you may have installed the version that works with python3 when you only have v2.something. booshi fucked around with this message at 18:51 on Jan 2, 2014 |

I realized that yesterday while watching some videos on getting it setup and configured to see exactly where I went wrong (I expected to see emulators listed even if there weren't any ROMs there). My ineptitude aside, it would have been nice if they would have included that in the FAQ or something.

I have a Raspberry PI (256MB Model B) that's been running Raspbian pretty solid for over a year. I recently picked up a BeagleBone Black and have been decently impressed with the performance improvement over the Pi. Overall I've seen a good 20% improvement in the BBB compiling with GCC and running things like UnixBench. Part of that can be attributed to the 1GHz clock speed of the Cortex-A8 vs 700MHz on the Pi, but I think the architectural improvements between ARM11 and the Cortex-A8 play a role as well. The downside to the BBB is definitely platform maturity. There's a much smaller community base to draw ideas and support from, and they're on the fourth or fifth hardware revision already due to issues that have been popping up. My unit died after a week and had to be shipped back for reflashing. Overall not a bad deal at $45 MSRP, but lack of availability has been driving the price higher at the few distributors that actually do have them in stock.

If you have to use a mini-HDMI to HDMI adapter and an USB device at the same time, you have to force a little bit one of the connectors, and that is definitely NOT good  That is a bad design

First, wifi dongles were a huge, huge pain to get working. Then, students were frying boards left and right because the tolerance for input voltage is only 5 +- .25V. Yes, a quarter of a volt for a platform that is also aimed towards those new to computing/microcontrollers. It's a promising platform given the larger amount of I/O and processing power but I have seen BBB's fail because you may have looked at them funny.

I powered it off for a pair of weeks. When I powered it back on, the USB (power thru mini-USB and network interface) was dead. Fortunately, I'm going to get a replacement when the thing comes back to stock. A pity, because I really like that small thing. uSDs are more convenient than SDs, and it is faster than the rPi (for what I want it). Now I just hope my cubietruck doesn't break

Has anybody had issues with their Pis losing SSH? Mine is set up as a wifi access point, but after a while it seems to lose the ability to accept SSH connections. It continues to act as an access point just fine and I can ping it, but SSH simply refuses. The only thing that will bring it back is a reboot.

Basically, /var/log/{messages,secure} && /var/log/audit.log on RPM distros and /var/log/{syslog,auth.log} on deb distros. Check to make sure it's actually tmpfs or actually 100% full before you do this, though. You may also want to try running ssh in debug mode (console cable, full path, it'll run in the foreground) to get hints if they're not in the aforementioned logs.

Ah, I figured out what the problem was. My pi seems to have a minor defect where the SD card slot is incredibly sensitive to pressure from underneath. I have it hanging on the wall because it won't work at all inside of a case, but even then simply resting against the wall would cause the SD card to become unreadable from time to time. I was able to cause SSH to drop by simply touching it. At least I learned a lot about fstab and logging trying to figure it out.

I wish someone would make a 'premium' raspberry pi that's the same chips but with good connectors that don't break. Also put some mounting holes on the board! How do folks attach the pi to stuff? I want to mount one on a board inside a project, but the best thing I can find is just wrapping tape around it and the board (which sucks). edit: Oh I guess I have an older board that doesn't have mounting holes? Yeesh that sucks, anyone have advice how to mount this thing somewhere? mod sassinator fucked around with this message at 22:04 on Jan 10, 2014 |

Then, once the machine is booted the SD will not be used anymore (unless you need to mount the /boot filesystem to update it).

In my experience generally RPis aren't great with pressure pushing up on the sd slot. Between 2 pis at home and my ~50 I have for my research project, most of them have issues with reading off of the card with too much pressure on the slot. The original case for my research project didn't account for the microsd adapter we use, and was putting pressure on the underside. I had to Dremel them all out a bit. With a case that I use for my home Pis, if tightened too much it puts too much pressure on the microsd adapter and causes problems. Usually I just have to fiddle around with it a little, or take it out and reseat it, and it's all good. I work with Pis so much now I can tell you from the lights if it is booting properly, and I can even tell network status from how the Edimax dongles flash. e: And speaking of mounting, what idiot chose to have only 2 holes? 3 would be much more sturdy.

MAME games seem to be finicky, meaning I can put the roms in there but most of them don't read...I'm working on a solution to this, it may just be taking them out of the zip archives, but i"m not sure yet. TG16 works flawlessly, as does the NES. Genesis and the SNES are up next on my list to use. I'm really thinking of putting FCEUX on there for the NES though because Retroarch doesn't have the features I like (like instant rewind and an easy way to take screenshots and the like). I got the whole thing to work finally after buying a powered hub. For some reason no controllers would work properly connected directly to the Pi. I think the power draw was too high. Oddly enough a Logitech wireless PS3 controller I bought 5 years ago ended up being the ticket. All in all, its been a great addition to my living room TV...hell, it's been the only thing I've used my McLargeHuge television for in a while.

I got a Pi this weekend and set it up with Raspbian to be an always on usenet box, with SABnbzd, Sick Beard, and Couch Potato as well as network file-server junk and such using an external drive. I still need to finish some things up with this, but I was wondering if it would be a better idea to switch to Raspbmc and run the usenet stuff on the PC that's usually on all the time anyway. The one thing I'm not sure about is making a shared folder on Raspbmc so I can just point the usenet apps to that directly and make it seamless. Was hoping someone here has already messed around with this idea, but if not I'll just grab another microSD card and try it on there (or more likely backup the Raspbian build and start over). Also the external drive sometimes doesn't mount right, not sure if I need to format it or something else, but it seems like the setup to make it automatically mount gets overridden by it mounting in the GUI when I remote into the pi. I'm not sure what's up with that since it worked fine for a while, then I started getting I/O errors when trying to add directories in console, but I noticed that it was in the GUI under a slightly different address. Maybe I hosed up the setup or there's some power issues at play causing it to turn off and remount.
