Slightly faster h.264 encode...

If I'm honest, I've been on the gentoo hard-float since I got it, and it's just darn slow. It might be an improvement over a soft-float, but don't have high expectations of it.

You can't expect much from a 25$ computer.

[n_K]

Well I mean, I kinda would expect it to be half decent, it's faster in terms of Mhz than an ipod touch but really doesn't seem it, EVERYTHING it does is much slower.

Alright for messing around on but they still well overplayed it's uses and expected performance, but hey kids are using it, making games on it, having fun so good luck to them!

[articuno1au]

They do appear to be great little media centers though >.<

I'm just looking for something to play streaming content off of a CIFS/Samba share. If it does that, I am happy :)

I am sure iPhone or decent Android phone would outperform Raspberry Pi by far. Only thing that RPI has is GPU with H.264 encoder, and this makes it useful for HTPC.

Right now even something like torrent client + USB harddrive + Samba share setup is flaky at best.

Bought a cheap DIY case to tide me through until I have the pennies for that posh one, 5 minutes to assemble and it looks pretty decent (This one)

Got mine today, but apparently I'm having problems writting the OS to the SDCard (red light and very dim green one)...

Edit: Nevermind... one of the SD pins was bended O_O, put it on place and worked again

Are you using Win32DiskImager from a Windows PC ?

If you still have problems, format the SDCard in Windows to FAT32 (might need to delete and re-create the partitions) and copy Berryboot files to it, just drag and drop, then put the SDCard into the Pi and try booting from it, it will let you install the OS from a menu

I use this free partition software to flatten the sdcards between installs

Sorry for missing your reply, nonetheless I thank you for your answer :D, it was a bended pin on the SD card slot, got it fixed and finally began tinkering with it, I'm trying to do an RS232 project with the UART port for automation purposes, there exist any IDE for this kind of computer? do you recommend one particularly? Thanks in advance!

So new 2.0 version of board announced - mine is not due to be shipped until OCT, lets hope get the new board ;)

http://www.raspberrypi.org/archives/1929

Upcoming board revision

[leesmithg]

I paid for mine sometime ago and it is on back order with Maplin, so this month my Pi bundle will arrive.

I got the case already to protect it.

Fingers crossed.

Apart from maybe the HDMI leakage I don't think the changelog would make a lot of difference to me, I'm not using the GPIO pins and doubt I ever will

Good luck getting the new version ;)

[+BudMan MVC]

I am very curious about the new i/o connector - it mentions clock and audio, wonder if this would allow for good say gps clock pps signal that would allow it to be used as a tiny time server??

Also hope the changes in the board don't - ie new i/o connector don't mess it up for fitting into the case I purchased ;) hehehe

hmm possibly yea, I just looked up my hardware info and I have a 2 code, meaning Model B Revision 1.0, I haven't popped any fuses yet, but only used keyboard, mouse and wifi adapter in USB

could a moderator fix the title, it is "raspberry" not "rasberry".

Introducing turbo mode: up to 50% more performance for free

Since launch, we?ve supported overclocking and overvolting your Raspberry Pi by editing config.txt. Overvolting provided more overclocking headroom, but voided your warranty because we were concerned it would decrease the lifetime of the SoC; we set a sticky bit inside BCM2835 to allow us to spot boards which have been overvolted.

We?ve been doing a lot of work to understand the impact of voltage and temperature on lifetime, and are now able to offer a ?turbo mode?, which dynamically enables overclock and overvolt under the control of a cpufreq driver, without affecting your warranty.

We are happy that the combination of only applying turbo when busy, and limiting turbo when the BCM2835?s internal temperature reaches 85?C, means there will be no measurable reduction in the lifetime of your Raspberry Pi.

You can now choose from one of five overclock presets in raspi-config, the highest of which runs the ARM at 1GHz.

The level of stable overclock you can achieve will depend on your specific Pi and on the quality of your power supply; we suggest that Quake 3 is a good stress test for checking if a particular level is completely stable. If you choose too high an overclock, your Pi may fail to boot, in which case holding down the shift key during boot up will disable the overclock for that boot, allowing you to select a lower level.

What does this mean? Comparing the new image with 1GHz turbo enabled, against the previous image at 700MHz, nbench reports 52% faster on integer, 64% faster on floating point and 55% faster on memory.

Other changes to the latest firmware include:

Temperature and frequency widgets

You can enable a core temperature widget for the lxde taskbar to see how close to 85?C you get (in the UK, it?s not very), and a cpufreq widget that will show the current ARM frequency when you hover over it. See here for more details.

USB interrupt rate reduction

We have enabled Gordon?s ?FIQ Fix? in the USB driver, which reduces the USB interrupt rate, improving general performance by about 10%.

WiFi is now supported out of the box

If your WiFi driver is supported by the default linux tree, or is based on the popular RTL8188CUS chipset, then WiFi should work out of the box. Boot the image with the WiFi dongle plugged in (a powered hub is recommended). Run startx and select ?WiFi Config?. You can scan for wireless networks and enter your wireless password and connect from the GUI. No need to install additional packages or scripts.

Improved analogue audio

Analogue audio quality has been improved.

Extra software installed by default

SmartSim and PenguinsPuzzle are pre-installed.

Well got mine the other day, and found my first project for it, ntp stratum 1 server via gps.

Found this great writeup

http://open.konspyre.org/blog/2012/10/18/raspberry-pi-time-server/

Ordered the cobbler kit and this gps https://www.adafruit.com/products/746

Hoping it will be here by xmas ;) so I will have some time to get up and running before the new year. Already have my N40L serving up time to pool.ntp.org on ipv4 and ipv6 but not really happy with the 5-10 ms offset I am seeing. With stratum 2 status, I want to get it down into the ?s range.

I also found this other guide about gps ntp on your pi, http://www.satsignal.eu/ntp/Raspberry-Pi-NTP.html with lots of great info and monitoring tips, etc. So it should be a fun first project.

Playing movies off the thing is fine, but those types of projects just don't satisfy my inner geek impulses like a stratum 1 ntp server ;)

Got my Pi a few weeks ago, got a case off Ebay and it's lookin pretty slick. Been using it as a media server however I want to extend the media playback a little bit.

I have decided to forgo a DE/Window System in hopes of raw performance. I wrote a tcp client in C++ that listens for commands from a Server app running on my desktop. The server app has a file system watcher that watches for text files I create with a PHP script that runs on a webserver I have on my desktop.

I am working to get it (I am almost there) so that I can go to 127.0.0.1/ see a list of all the videos/shows/movies on my PC click it on any browser (Phone, Tablet, etc) and have it play on the Pi.

I am running into an issue with OMXPlayer where it hangs until my app closes (even after I have launched omxplayer). After I close my app though it fails to re-connect when opened.

So I have put it on a slight hold for now. Right now however, I am looking at direct Framebuffer writing code that I may be able to create a basic interface/window without the need for X.

As I am very weak in C++ it's a good learning opportunity.

"Improved analogue audio

Analogue audio quality has been improved."

o`rly?

Can anyone (preferably with a V1 board) comment on this? Is that annoying static 'BOMPH' still there when audio playback is started or stopped?

Got a V 2 (Model B). Pi tonight. Played with it for a couple of hours. Got me inspired. :)

So far, I am thinking about putting the following on it (as long as it works) all in the same boot:

Cups Server

Asterisk Server (To replace my leased one I have now)

Web Development Server w/Mysql and PHP (Lamp variant probably)

Mail Retrieval and Server (So I can pick up my mail from the Pi similar to an Exchange type of server)

For storage, will be offloading data onto external thumb drive. Eventually have the mail server drive an LED to indicate messages incase my PC is offline for any reason. Plan on buying a case eventually for this as well, but need to wait a bit before I do that.

All things I believe carry a super low CPU load so don't think that would be an issue. I spotted an Asterisk server for the Pi through their store tonight. Got my mind running.

-------------

I played with the XBMC port for the Pi and was impressed with that, except for an apparent known issue with Food Network and other videos not playing. What else has everyone else here been doing with yours?
