if making bulk orders do count me in.
do you think this can be made into an intrusion protection system? will sit inline between the internet and my router. maybe can even have another one made into a dedicated firewall |

for those who plan to get XBMC running on the Raspberry, is there any detailed instructions to installing and setting it up?
Also is audio output through HDMI or the 3.5mm audio jack? |

I also already have a NAS/Torrent downloader. so if I do get the raspberry it will be purely as a media player.
among the various XBMC ports if there any which we do not need to log in? Coz from what I understand OpenELEC once the raspberry boots, you still need to log in. |

can anybody recommend any other USB nano wifi that can be used with Rasp+RaspBMC or equivalent?
saw this on element14 (MICRONEXT - MN-WD552B - DONGLE, USB, 802.11N, NANO SIZE with some great instructions here on how to install. but the adaptor is RM73! So i found this on dealextreme.com Ultra-Mini Nano USB 2.0 802.11n which according to some reviewers uses the Realtek RTL8192CU chipset, while the element14 Micronext dongle uses the Realtek RTL8188CUS. The RTL8192CU can use a 2x2 antenna and only cost ~RM30.  FYI there are some USB 1A adaptors also on sale in dealextreme.com for only USD3-5. Although I think they have issue with passing current on the 2 data connectors - solvable by bending the two connectors out of shape. |

we are not the only one.
http://www.element14.com/community/message/59548 but curiously what could we do with the extra RAM? |

I just called element14 just now. THe black box version and the power adapter is going to take 6-8weeks to stock up.... darn...
Edit: Yeah! just ordered. Hopefully come soon. At least now I dont need to think about turning my NAS into a HTPC/NAS anymore. Can use the Raspberry to play on the TV. This post has been edited by CocoMonGo: Sep 4 2012, 12:34 PM |

QUOTE(skywardsword @ Sep 4 2012, 12:35 PM) If you have usb - micro cable, and a tv with usb cable that can provide power, or even 2001fp dell monitor, should be fine leh. I am going to leave the Pi plugged direct to the power socket and connected to the TV. It is basically going to be used by my family so there is no way I can hope they can "sudo halt" the thing every time they on and off it. Just remember, when you plug in the micro usb power cable to the Pi, and unpluggin... dont use the silver capacitor as a holding spot... grab the whole pcb and pull the plug. Capacitor can break off. Thats my tip on using your Pi caseless. (I connect a old ups to the psu and just use the ups's on/off switch... so I dont have to pull the plug after sudo halt btw what is the difference between "halt" and "shutdown"? I tend to used "sudo shutdown now -h" |

QUOTE(skywardsword @ Sep 4 2012, 02:29 PM) I donnu. I get blank screen after I do the halt. Says system going down then blank screen. I will never know if CEC is working LOL.... but I remember seeing on raspBMC that it is not yet working. Not planning to use that for now though... for me I will enable XBMC remove via Wifi with my Android phone which I understand is already working with the current RC. There is another option to use the Rapoo wireless keyboard+mouse combo I have which I purchased for my server. Since it usually sits there doing nothing I think I will just use it to control the raspberry. Hopefully the Rapoo works just as well as it did with my Ubuntu.Also, Element14 just call me saying "you nice guy, but your order cannot go thru leh... haha no bring in stock" There goes my 512mb - 1st in queue order! Added on September 4, 2012, 2:33 pm Also, you got CEC working? I yet to get it working since i running raspbian with xbmc install after from some pre-complied download. Without CEC support... how your family work the keyboard to play media...kind of inconvenient if you get what i mean. So you poweron TV, and raspberry powerup. Make sense. Now if one switch and one remote works woohoo. |

OK i got dumb question. Now that the cubieboard is announced I am curious.. the raspberry pi is 700Mhz core vs the cubieboard of 1GHz, but both have the Mali-400 GP, so
1. Does this mean the cubie might be more capable in movie playbacks? Basically is the GPU's ability tied to the CPU's in SoC? 2. Does this mean we have to wait for another cubieboard port of XBMC like raspBMC? |

raspBMX loaded and playing currently via cable from my HP microserver. good so far... very minimal stutter which I think is due to my slow router rather then the pi itself. What do you guys overclock yours to? I only manage CPU@ 825MHz and GPU@375MHz.
BTW is it required for us to manually upgrade the firmware? if so how to do it? didnt seem to work for me based on this https://github.com/Hexxeh/rpi-update |

QUOTE(skywardsword @ Sep 17 2012, 01:29 AM) If nothing broken. Probably dont need to update. I have not had much problem with 720 or 1080p so far... 1080p i dont have many files to try but so far so good. slowdowns occured in some videos today but no problem after restarting smooth throughout the whole 2 hours plus. the OC of the GPU really helped. but the chip is blurdy hot, I even put a "massive" heatsink from a old south bridge chip and it was hot. still waiting for the RAM heatsinks for the other power transistor and ethernet/usb controller.I am not 100% familiar with raspbmc. While I dabble with debian wheezy/squeeze and then raspbian. I did do the firmware update via the command line. Now, I think with raspbmc, it is suppose to update itself. The kernel??? I would not update unless instructed via the raspbmc website. I know that running sudo apt-get update/upgrade via the command line did break my first installation of raspbmc. (Let us know if other Sifu knows otherwise.) Note: I played one of my oldest 1080p file of Final Fantasy movie via network share smb on a win7pc. It lags every 5-8seconds. I noticed that, I have mainly just 720p files. 1080p files just takes too long to down and upload. So I have given up on those. 720p files mostly played fine. Some do give problems. I say about 8 out of 10 were fine. Since I setup my network share, I was able to try out lots of different files. IDx subtitle files dont work with xbmc. I give the Pi a score of 7.9 out of 10, as a stream to output unit in the living room, it is cheap and relatively good. If your playing mainly 720p, you should encounter problem 1 in10. 1080p, probably a bit more problem, since streaming might lag things up more. Hardly possible to move a 10gb 1080p on the Pi. 200-500mb 1080p Music videos - those are very very good. Even tested networked shared 1080p of that size, seems to work... may just be the particular file and audio encoding. I think the multi-subtitle, multi audio track files, will encounter more problems.***just a guess |

Well guys, after a whole week of testing I finally decided to used Xbian vs Raspbmc. These are my opinion and your mileage may very depending on setup and hardware.
I personally find that Xbian is a better XBMC distro than raspbmc as I find it more responsive. Even when overclocked to Xbian speeds, raspbmc is more sluggish and unresponsive when compared to Xbian. It might be a power issue as when I plug in extra power the issue is gone, HOWEVER, with Xbian this issue is not present with the lower power supply (currently running on a 1A adaptor). I find Xbian to be easier to install too (writing a complete image into the SD card) rather then installing from the pi over the internet with raspbmc. and after installation, i notice in the raspbmc setup there is an allocation of 0.1GB space, which while does not do anything, doesnt look as neat. I am currently using the pi with a Rapoo wireless keyboard and a USB wifi dongle with a Realtek RTL8188CE chip. while raspbmc gets working with the Realtek out of the box, I personally do not find it a big deal to install and setup the dongle through Xbian. In conclusion: Xbian - more responsive, lower power consumption(?), easier to install, cleaner install This post has been edited by CocoMonGo: Sep 23 2012, 09:32 PM |

Well guys last night I finally decided to overvolt my pi initially by using the preset turbo mode in the new kernal then overvolt to 8. I am now at 1.15GHz, 600mhz core & sdram clock. The reason I overvolt and overclock like mad was because the pi (running Xbian) had trouble keeping up with high bitrate movies smb streaming from my samba server - WiFi or cable. I deduced it was not my network problem since my laptops can stream all my movies without problem. With the new kernal and overvolt it now plays 95% of my movies without problem, except for some really high bit rate DTS 1080p movies.

QUOTE(willer @ Oct 8 2012, 03:40 PM) Standby with some heatsink uncut south bridge heat sink muahahhaa Added on October 8, 2012, 3:41 pm Agree  anyway I figured out why the wifi performance is so slow. The wifi dongle is utilising the cpu's processing cycle to what I would presume "decode" the wifi? I dont know the proper term. I figured this out when another user who used the same dongle said his CPU utilisation was up 3-5% when plugged in. no wonder I have to OC so much. I am going to order another dongle. Hopefully the next 1 not so suck. The dongle you see that says "Equip" the the wifi dongle in question. |

QUOTE(skywardsword @ Oct 8 2012, 11:13 PM) I have the same heat sinkX2. But I cut some other 1inch tall heat sink into chip size. (too lazy to glue it on with thermal compound, since my rasp-pi is still on 24X7 and I dont want to bring it down.) that was the surprising thing - I tested my pi to stream the same 720p movies using a CAT5 and CAT6 cable but the jerkiness of the movies persist. the only method to play 1080p or 720p movies flawlessly was to use a USB HDD which played flawlessly. I would put it on the next time I upgrade os to xbian. I pre-wire the living room with an extra cat6 cable before I even order the raspberry pi so not using wifi. But I think it uses the same chip as the usb.... so the load is probably there. Aside from that, due to snail pace internet, the most I have is 480p/720p.... just only rarely 1080p. Those do slow down... but not too concerned. 720p stream from samba share from pc... plays fine but some subtitle in say horriblesubs' naruto/hunter ect do skip one-two sentence. <so I do have to upgrade the os soon and hopefully overclock the pocket rocket) BTW i only use thermal compound, good enough it seems. Unless you drop the pi or shake it a lot like in the car, you should be able to live with just using paste vs something more permanent. Oh yeah the new xbian/kernal from the foundation is awesome - especially since they sanctioned the turbo mode. I find it far more stable allowing higher OCs. |

QUOTE(skywardsword @ Oct 9 2012, 10:54 AM) I mistype... I was going to use Arctic alumina, thermal adhesive.(the one with 2 tubes that gotta mix together one) once I put that one... I think no case will fit... since the heat sink is 1inch tall. oh yeah i noticed it just make sure your "force_turbo=0" before reboot. Anyway it is a little too late for me. I noticed and fixed that the first time but forgot to do it the second time when I corrupted my first Xbian 8.1Beta install and had to reinstall. edit: downloading xbian 0.8 -- I read a note a xbian... dont turbo!!!! will get warranty voided. They made a mistake it seems. personally i wouldnt worry about it. the initial idea the foundation did not support OC was due to concern of the heat generated which would cook the processor. but soon they realise even when OC'ed it would take many years before the board deteriorated hence the recent sanctioning of OC and OV in the pi. I dont have the articles which I read this about but you can google it up. Added on October 9, 2012, 1:52 pm QUOTE(willer @ Oct 9 2012, 01:15 PM) Nice cut, nice heat sink thanks man.
