[Raspberry Pi General] stephj:
I have ported an old PC 'C' program across to get it to calculate π (pi) to a million decimal places. It took 2 days 7 hours. Not bad for a 700Mhz 32 bit processor.

In comparison a Core 2 Quad 2.6Ghz PC can do the same job in 15 minutes, but it is not comparing like with like. The latest PC program spawns four independant threads, one for each core, each using an x64 assembler function under Windows 7 (64 bit) to divide out the arrays. This trick allows an __int64 array element to store 18 digits of the final answer.

The Raspberry Pi has to do it the hard way, 9 digits at a time and no multiple cores and only at 700Mhz.

Also using it as a learning platform for 'C' development under X (Rasbian LXDE desktop). Currently trying to port over '5x5' using GTK2+. Once I can get it to draw a black square on the main window, we will actually be getting somewhere. The learning curve for all this stuff is pretty damned steep. It is similar to the Windows GDI, but with enough differences to drive you mad.

Still at it, I'm not giving up!

Update: Cracked the square drawing problem. Now dealing with the mouse button clicked signal. Nearly there!

More: Cracked the mouse click and the resize window issue. Now on to creating a menu bar out of thin air to place in the window. A window/Application icon might be nice............

More: Got the menu bar to work, but it won't resize along with the window when that is resized. Still at it.............

I was thinking this would be sweet to sync with my work scheduled and turn on my heated seats 5 min before I have to leave every day depnding on the temp and batt. voltage. as well as tie in to audio and OBD2 logging with sync to my pc over wifi whenever I get home.

*apologies for almost blowing my mic on the gnex :P

Recently I've switched to Xbian over Raspbian RC4. I also run a version of debian squeeze hf with full touchscreen support but still none inside of xbmc.
[Raspberry Pi General] funkbuqet:
I should be getting mine in December! I am planning on using it for a bit a an xbmc head (linked to my main media center) and also see if I can get it to run mame efficiently. If I can I want to get another so I can build my kids a mini mame arcade cabinet. My daughter is 4 and still too small to play my man-sized cabinet solo.
[Raspberry Pi General] lbusoi:
can you post what you din and how you did it?

this sounds very interesting and all the other projects but can we have the HOW TO of everything that you did for the noob ones among us?

Thank you

Still waiting for the dispatch @rs-online but already it has the destination. It's gonna be another 'home server'. It will host an http/ftp server for my university projects, will run ekg (internet communicator) with my account, will work as a home storage unit and a network printer. Of course it will be destined to work 24/7.

PS. Does anyone know if there's a Debian distribution for RPi that comes with no desktop environment? I mean - pure shell.

PS2. All these above is currently running on an old Athlon64 X2 @2.2GHz, so it's quite a power eater. That's why I was excited when I first heard about RPi ;)
[Raspberry Pi General] stephj:
The Raspbian 'Wheezy' image starts into a menu which gives you the choice of setting up the Pi to startup in either 'X' or a raw shell prompt. Take your pick.

There is also a neat little utility to expand the root filesystem to the available space of the SD card if it is larger than 2GB, followed by a restart. It will save you having to mess about with parted or gparted live etc.

Set it up the way you want, then login straight into the $ prompt.

'X' is still there, 'startx' will fire up the X/Gnome desktop, otherwise stay at the shell prompt.

ArchLinux starts as a shell only interface, it's lean and mean, but you are on your own after that.

P.S. There is quite a good guide on how to start the thing up for the first time here:

http://www.engadget.com/2012/09/04/raspberry-pi-getting-started-guide-how-to/

It is a pity it came out a few months after I had done it all the hard way.

Worth remembering...... Power on the monitor first, and wait for it settle down and report 'No Signal' etc..........THEN power up the R-Pi.
[Raspberry Pi General] mihaum:
stephj, thanks for you reply. I've been working with Debian since 2007, so I will stay with it ;)

I will for sure go with Wheezy ;)
[Raspberry Pi General] m2xtreme:
I was thinking they should create a minimal install for Raspbian much like Ubuntu and Debian already have, but unistalling X and LXDE isn't a big deal (if you're really crunched for space). Maybe someday.
[Raspberry Pi General] mihaum:
It's not about space ;) It's just I don't need any desktop environment ;p

Hi Folks

This seems like the right place to stick these links, as much for my own benefit as well as everyone else :D

A Cambridge ( UK ) Univeristy Tutorial on common operating system development concepts, Entitled Baking Pi - Operating Systems Development

That sounds right up my street :D They also have some other interesting tutorials on there, such as a temperature sensor using GPIO and a basic imagine processing tutorial. Fascinating stuff. :good:
[Raspberry Pi General] stanburn:
Actually, I made the raspbian distro it came with into a "shell" only/minimal install. I just uninstalled all Xorg/Xserver packages through apt-get. Then just to be sure I ran aptitude to track down all the unused packages that would've needed any gui package and uninstalled those as well.

You can do this on qemu first because aptitude runs really slow on the pi itself. When you've cleaned up your image, you can test it on the pi until you've removed everything you don't need.
[Raspberry Pi General] trevd:
Hi Again Folks, While we're on the subject of distro, I try this one for about half day on my main pc

Tiny Core Linux It's effectively an 8MB Linux distro using our old friend busybox at it's base.

Here's the kicker though, There;'s only a x86 Distro of It, So there's ya project, Porting to arm. :laugh:

I ordered a Raspberry Pi model b and I will receive it this week. I will start by making an extended tutorial about how to OC. And probably more tuts but havn't decided what that will be. Next to the tuts, i will also make a very light linux distro to use on the Raspi. which contains a lot of tweaks / handy tools but wi remain clean/fast

I've had it as a media player with openelec/raspbmc then as a vpn/firewall. Currenrly waiting for another one, new model B. Now im messing around with using it with the nfc shield I recently got from adafruit. Next im waiting on some hardware and I will use one for the ambpi light project, which hopefully works as good or similar to ambilight.

Be sure to send any interesting projects to the MagPi magazine, since we are always keen to hear about the interesting projects everyone is doing with the mag.

Glad to see the Raspberry Pi finding a home here on good old Xda!
[Raspberry Pi General] dr.devman:
What is this? Sorry for being nosey. Just curious
[Raspberry Pi General] meltwater:
The MagPi is a free community magazine for Raspberry Pi users. We've been going since May and Issue 8 will be released on 1st Dec.

Have a look on www.themagpi.com

There are so many excellent projects going on, it makes a good platform to bring the information together, in a traditional magazine format. The process tends to make for more complete and easy to follow articles than you typically get with blog posts and forum entries.

Personally, I like the hardware interfacing since that is something which isn't so easy to do on the phones. A good mix of electronics and programming!

Is the RPi working well as a media server? I've been playing around with DLNA servers to interface with a Samsung BluRay player or Humax TV box (Twonky on a Linkstation - unstable, Standard Win7 media server on PC - drops out). Yet to try out much else yet.

So interested to see how well it works and what the set-up entails.

Someone mentioned a multi-monitor setup a few pages back...synergy works on the RPi, so as long as you boot directly to XWindows you can share your mouse and keyboard over the network and save yourself some desk space.

Arcade Emulator

I have used my Raspberry Pi to fix an old arcade table that had a busted board. I'm running AdvanceMAME on Raspbian.

I used an HDMI to VGA converter and another VGA to CGA converter to get it to output to the old arcade monitor.

To get the controllers working I used a usb microcontroller and adapted some code to make it act like a usb keyboard. I did this because I was originally prototyping with an old laptop. When I get some time I plan to use the Raspberry Pi's GPIO pins for the controllers.

I also managed to pair a ps3 controller to it using a bluetooth dongle.

The sound is an issue. The 3.5mm output has a high output impedance, so it needs to be amplified. At the moment I need to use headphones.
[Raspberry Pi General] Jeffail:
I have seven pi's right now. One is hosting my website, four are a tomcat cluster for serving my instant chat app, another is a seedbox and ssh portal to the other pi's and I have a seventh in my parent's house as a backup server.

I've gone pi mad, they're just simply amazing. The price, the power usage, the size. If you can find a way of clustering them to suit your needs I'd recommend them for any purpose.

Tube Radio added internet radio

Hey Guys!

Here is my contribution with my creation with a Raspberry PI.

I took the old radio from my great grandfather out of 1955 and build an internet radio in it.

The sound is great!

Since i have used the old tube amplifier in the radio itself.

Since i'm a new user i can not post links :(

Search on youtube for:

"1955 Internet Tube Radio with RaspBerry PI "

And you will see ;)

What do you think?
[Raspberry Pi General] Nizda1:
This is really cool. I just set up that ras pi transporter project with a nexus 7 and a pi. It actually works once it's polished it will be a great alternative or alternate usage for miracast. This is definitely awesome being able to play games or anything completely wireless to your tv. The project details are on the main ras picture blog, as you have to set it up on both devices.

I use my pi out in the field when I'm working on tech support calls. I have a 3G USB dongle hooked in as well as a Bluetooth dongle. I power it with a backup battery designed for iPhones but it has the same output as required for a pi. It is inside a small box with a4.9 screen on the cover. It may be slow but very fast for a computer so cheap! I love my pi and you all should too!

I'm in need of more streaming stations for my Squeezebox/squeeze server - already have 7 with a couple acting up occasionally. Enter the RPi and squeezeplug.

Got two yesterday, have 'em both set up and doing what I want. I'll be working on some hardware for improved audio, and hopefully Squeeze play which shows promise.

Who knows what else I'll end up doing. These are too fun.

I acquired an old 27" tv from my brother (2008 creation, flat screen) that powers on and turns off nearly 3 seconds after. Ordered a new capacitor so that should fix my problem. Once the tv is up and running I will install the PI within the tv, ultimately creating a computer that works entirely off out of the tv screen. I also want to get some emulators running as well in order to play all the classic games. Thankfully the tv is very lightweight, and can be picked up with one hand.
[Raspberry Pi General] starnostar:
I use mine as a dedicated "NAT Traversal Toolkit" that doubles as "MitM/ARP Spoofing On-The-Go Protection Toolkit" it sits next to my router.... I have yet to find a firewall/NAT I cant bypass, and every device I own can use at least one of these. I usually end up using the L2TP/IPSEC VPN though, as its the most compatible whilst retaining good payload encryption.

- L2TP/IPSEC VPN server

- OpenVPN server (two instances... one TCP and one UDP on different listening ports)

- PPTP server

- SSH Server /w tunneling + X-forwarding (RSA Only)

- Iodine (tunnel over DNS layer)

- ptunnel (tunnel over ICMP layer)

- Squid proxy (compiled /w SSL and SOCKS support)

Been running like a champ since I finished setting it all up months ago. I plan on getting three more... a freeradius server for WPA-Enterprise, and owncloud server, and a dedicated certificate authority.

[Raspberry Pi General] oribunokiyuusou:
Perhaps you could set up a guide for us here on this forum on how to get each of these services up and running? I know I'm interested in a few.
[Raspberry Pi General] starnostar:
I was actually planning on it... Especially for L2TP/IPSEC, which gets asked for on nearly a daily basis. Kind of expected though given the absolutely absurd level of complexity and fine grain control you are given over every single aspect of it.
[Raspberry Pi General] oribunokiyuusou:
The L2TP is particularily interesting, especially with a RADIUS server for PPP authentication on the LNS.

With IPSec, what are the best phase 1 and phase 2 hash and encryption that you can get on the Pi without stressing the CPU with encapsulation/decapsulation??

gonna do the regular xbmc mediacenter stuff. so far i've figured out how to send a WOL when accessing any item on the home screen, without the need to start it manually. next step is to get my pc to suspend when the nfs is not in use. but i guess i have to move first, WOL is kinda lame if you only have wifi cos the gf starts *****ing when you drag that 10m ethernet cable across the living room...

once that works fine i'll find some way to use spotify controlled by an android device without a hassle. if anyone has any input on that topic give it to me :laugh:

an alternative solution would be to stream the music from the android to the pi, via wifi or even maybe bluetooth, as i have a spare bt dongle which might work with the pi (haven't tried yet).
[Raspberry Pi General] mintjustin:
My RPI can act as an XBMC box just fine. It might not be as smooth as I would prefer but 1080p h264 video are running so I can't really complain much about it.

My plan is to install minidlna to see if this cute little thing can act as dlna streaming server or not.
[Raspberry Pi General] hikaricloud:
Wow, lot of nifty projects in this thread. I feel kinda silly with mine, but I just have an OpenELEC installation sitting on there right now. I'm in the process of organizing all my media (at least video media to start with) so it can interface with XBMC for maximum "prettiness" I guess (thumbs, fanart, etc etc). So far it has been working well with files just housed on jump drives, however I'm in the process of figuring out how I want content to be sent to OpenELEC.

My first idea was just a big ol' external plugged in. I just bought a 3TB to replace my 2TB backup external, so I was going to use the 2TB, but then there's the decoding issue, since the Pi hardware doesn't do a lot of decoding on a hardware level from what I've heard, without purchasing additional licenses. So far I haven't had any issues playing anything, but then again I haven't researched what wouldn't work in relation to my collection yet.

Second idea was going to be a NAS Box, which I could do but need to mod my "Road Cone" PC case, since it can't house more than a single HDD right now (super old Gateway 2000 gigantic tower spray painted orange. I know it's awesome. I'll post a picture later rofl.)...I'm thinking of cutting the hard drive bay out of my old computer case and re-purposing it for my Nas box. This is my preferred idea, however I'm still relatively new to NAS software and I'm unsure how differently encoded files will translate to the OpenELEC installation, so bleh.

Third was just using my main PC as a Plex server since that'll take care of any decoding issues. Problem with that is my main machine is no longer reliable, especially for a glitchy memory hog program like Plex. Bleh again.

More on topic, my friend is doing something WAY cooler with his Pi. I showed him this article I stumbled on and he immediately said he wanted to do something similar. I'm awesome at Christmas presents apparently.

I would like to make an ownCloud-server out of it, but I found some reports on the net that it can be quite sluggish. Anyone already has experience with that?

Also I will have to learn a lot, cause I have no experience yet in securing servers...

Can anyone point me to a site or help me setup my raspberry pi to act as a surveillance station for my home ip cameras?
[Raspberry Pi General] Cab121:
Depending on the IP demand you might want to wait for the official raspberry camera to be in production. It has the capacity of a $600+ Axis camera at under $50. Sits directly on one of the 2 unused port and is made specifically for the PI. I have yet to find anyone doing any relevant or largely successful streaming with the PI to date. Though if you venture to the official Raspberry PI community you will find a few hack projects.

This is my project...I have yet to actually start on it as the parts are on their way to me as we speak...

But I'm going to make a 7" laptop/netbook with the raspberry pi...but it's all going to be mounted inside a hardcover book...the keyboard will be a bluetooth removable keyboard with a trackpad and it will include a 64 gb flashdrive as storage...

this is my first project, I'm going to delve into more projects but this is my first..
[Raspberry Pi General] darksabre_x:
Good question. It's only been up a few days so I couldn't answer that just yet. There are a lot of factors that contribute to data usage on an indexer. The number of groups being indexed, whether you're backfilling or not, and how many days of retention your database is set for.
[Raspberry Pi General] Ticklemehballlz:
Mmm raspberrys!

I only heard about these the other day from my 14 year old brother, But they look pretty sweet!

I'd love to get one up and running for some hacking/pentesting but my backtrack laptop seems to be suffice enough.

So i cannot really think of a very good use for one, Though setting one up as a wee seed box would be great! means I don't have to have my Gaming machine running all night, and when my partner logs me out of my Account on ubuntu and my torrents stop seeding that pisses me right off aha, So a seperate little Pi with Rtorrent running on it would be cool.
[Raspberry Pi General] Kevstyle:
My ideas for the Raspberry Pi

I think i will use it for these projects:

-XBMC : Playing music/videos to the TV/Phone & Backwards like Phone to TV.

-Remote TV Server: Playing a stream from PC to Raspberry (Like a PVR, but using the internet... It will be own media that i own, maybe make a service for it)

-Webserver: Experiment: Test apache & php

-...

I dont have much ideas yet so ;P We will see what i actually do when i get one. :cool:
