Do the GPIO serial pins need root to be accessed from a python script? I am making a sunrise alarm clock with web based controls, and to do pwm dimming on the LEDs without jitter while also using audio, I'm going to use either a bare ATmega or an Arduino controlled over serial. I could use the USB serial on the Arduino, but that'd waste a $30 board. I'd rather use the $3 chip hooked up directly. I'm also debating using an i2c led controller, but python tutorials for i2c tend to call for root privileges. EDIT: Never mind, I'm an idiot. Serial does not need root on Linux. I'm still not 100% clear on if i2c needs root. TVarmy fucked around with this message at 15:53 on Feb 3, 2013 |

I decided to try out the Airplay as well this afternoon, spent $3 on a jailbreak app that will allow me to mirror HBO Go and MAX Go, totally worth it.

Does anyone know of an 802.11N wifi adapter that will work OOB with OpenELEC? I have one with the RT5370 chipset, but it refuses to connect. All of the settings are correct and LSMOD shows the driver as loaded. I just want something which will work with no hassle.

AirPlay in XBMC works brilliantly for the most part, with two major caveats: Mirroring isn't supported, and DRM-encoded videos aren't supported.

Also depending on the adapter you may have to use a powered hub. frumpsnake fucked around with this message at 03:01 on Feb 4, 2013 |

Thanks! Started googling about USB hubs and got this page, which coincidentally uses the exact adapter I have: http://www.mike-worth.com/2012/11/26/adding-wi-fi-to-a-raspberry-pi-without-a-powered-hub/ So it looks like you are correct in that it requires a powered hub. Oh well, I should have done my research before I purchased. A comment on that page led me to the Edimax EW-7811Un, which apparently works well with no hub. The amazon page has hundreds of five-star reviews, including many about the Pi. I think I've found my dongle of choice.

Raspberry High now transmits status messages to #yospos on synIRC when it changes mode. I've been coding a fair bit, testing extensively, and learning about all sorts of fun stuff like how to poll serial in Perl, and how to build a usable UI for something that could burn a house down out of four buttons, a pot and a 20x2 LCD. All I need to do is hook in Net::Twitter tonight, and we will have fulfilled the original scope of the project, which was to create 'a bong that tweets when you hit it". More in the yosthread, we're getting down to code and such at the end. http://forums.somethingawful.com/showthread.php?threadid=3507531 http://raspberryhigh.wikia.com/

I'm in South Korea looking to buy one of these to replace an old AppleTV that I sold. One of my friends is visiting United States right now but is there any place that I could possibly order to have delivered to California by the 18th? They are $60 here. Also deodorant is $12 a can. politicorific fucked around with this message at 14:14 on Feb 6, 2013 |

I ordered mine on the 4th from Newark (Canada, but I think they share the same stock?), and even though they said it was in stock, the order is backordered until the 18th. Unless you can find other sites that sell it and have stock (and their website doesn't lie about it being in stock), then you might be out of luck.

Little tip: if you want to run a breadboard based Arduino compatible chip off of 3.3 volts to avoid voltage shifting and multiple boards, it is possible, but you have to set it up with the right boot loader and fuse bits so it runs at 1 mhz to save power and run more reliably. The slowduino hardware files worked great for me on an Atmega 168. This assumes you don't want an external oscillator, which apparently helps the chip run a little faster. Serial works better at 4800 Hz, but it was great for my application (chip that reads serial bytes intermittently to control pwm off its own clock, instead of an external clock like a TLC 5940). This is way better to me than using a whole board and logic shifter just for pwm.

What kind of performance does a rasp pi have as a file server? I just did a bad test by copying a bunch of tiny files off my xbmc pi and it was going just over a megabyte. Not really fast enough. Does it work better using a USB disk and NFS(and not running xbmc)?

Its size and cost makes it a decent fileserver if you need something portable but for home use I'd still go with the Packrats unite! The consumer NAS/storage megathread suggestions.

I haven't tried OpenElec but the one thing that turned me away from it when I looked at it was that it's not based on any distro and therefore doesn't have a repository of packages that you can install if you feel it is missing anything. Raspbmc and Xbian are Debian based so you can get all the debs you want.

You need it to share wiring with your obligatory whacky inventor breakfast Rube Goldberg machine, so you hit five buttons and after hitting yourself in the face with coffee and toast, you accidentally shoot the boxing glove at your friend at the door. Seriously, though, it'd be kind of cool to set it up to push images to your phone of who is ringing your doorbell.

After trying Raspbmc for few days I decided to check Openelec yesterday and now I regret that I haven't done it earlier. The only aspect where Openelec somewhat lacks compared to Raspbmc is image file and SD card preparation. First I realized that Openelec has built-in realtek wireless drivers and I don't have to apt-get, which was nice. Yes, Openelec does not have package repository, but I actually see it as an advantage for built-for-purpose system. Then I spent only 5min configuring wlan via SSH on Openelec vs 30min on Raspbmc and disconnected LAN after which is important for me since I don't have LAN socket near my TV. The concept of openelec xml configuration files vs oldschool "linux way" in raspbmc seems to be more user-friendly. Finally XBMC on openelec felt much more responsive, stable and less laggy and remote control from iphone was smoother.

I've just bought a wifi dongle for use with my Pi and, as much as I try, I can't get it to work. I remember reading that older Pi's (mine is one of the initial shipment) can't always power wifi dongles without using a USB hub, but newer Pi's have been changed so they're able to. If I pick up a new Pi, am I likely to be able to get the wifi working without a powered hub?

The list of compatible RPi devices has comments on if those NICs need outside power or not. The two I've bought are marked as "work fine without a USB hub" and do just that.

I went with Raspbmc originally because it was a bit easier to set-up but now that I have OpenElec installed and my Raspberry Pi overclocked, it's a night and day difference. Raspbmc didn't hold a candle to my AD10 + OpenElec, Raspberry Pi + OpenElec is a great alternative, especially at the price.
