  • RPi and Java Embedded GPIO: Sensor Connections for Java Enabled Interface

    - by hinkmond
    Now we're ready to connect the hardware needed to make a static electricity sensor for the Raspberry Pi and use Java code to access it through a GPIO port. First, very carefully bend the NTE312 (or MPF-102) transistor "gate" pin (see the diagram on the back of the package or refer to the pin diagram on the Web). You can see it in the inset photo on the bottom left corner. I bent the leftmost pin of the NTE312 transistor as I held the flat part toward me. That is going to be your antenna. So, connect one of the jumper wires to the bent pin. I used the dark green jumper wire (looks almost black; coiled at the bottom) in the photo. Then push the other 2 pins of the transistor into your breadboard. Connect one of the pins to Pin # 1 (3.3V) on the GPIO header of your RPi. See the diagram if you need to glance back at it. In the photo, that's the orange jumper wire. And connect the final unconnected transistor pin to Pin # 22 (GPIO25) on the RPi header. That's the blue jumper wire in my photo. For reference, connect the LED anode (long pin on a common anode LED/short pin on a common cathode LED, check your LED pin diagram) to the same breadboard hole that is connecting to Pin # 22 (same row of holes where the blue wire is connected), and connect the other pin of the LED to GROUND (row of holes that connect to the black wire in the photo). Test by blowing up a balloon, rubbing it on your hair (or your co-worker's hair, if you are hair-challenged) to statically charge it, and bringing it near your antenna (green wire in the photo). The LED should light up when it's near and go off when you pull it away. If you need more static charge, find a co-worker with really long hair, or rub the balloon on a piece of silk (which is just as good but not as fun). Next blog post is where we do some Java coding to access this sensor on your RPi. Finally, back to software! Ha! Hinkmond

  • why are my players drawn to the side of my viewport

    - by Jetbuster
    Following this admittedly brilliant and clean 2d camera class I have a camera on each player, and it works for multiplayer and i've divided the screen into two sections for split screen by giving each camera a viewport. However in the game it looks like this I'm not sure if thats their position relative to the screen or what The relevant gameScreen code, the makePlayers is setup so it could theoretically work for up to 4 players private void makePlayers() { int rowCount = 1; if (NumberOfPlayers > 2) rowCount = 2; players = new Player[NumberOfPlayers]; for (int i = 0; i < players.Length; i++) { int xSize = GameRef.Window.ClientBounds.Width / 2; int ySize = GameRef.Window.ClientBounds.Height / rowCount; int col = i % rowCount; int row = i / rowCount; int xPoint = 0 + xSize * row; int yPoint = 0 + ySize * col; Viewport viewport = new Viewport(xPoint, yPoint, xSize, ySize); Vector2 playerPosition = new Vector2(viewport.TitleSafeArea.X + viewport.TitleSafeArea.Width / 2, viewport.TitleSafeArea.Y + viewport.TitleSafeArea.Height / 2); players[i] = new Player(playerPosition, playerSprites[i], GameRef, viewport); } //players[1].Keyboard = true; } public override void Draw(GameTime gameTime) { base.Draw(gameTime); foreach (Player player in players) { GraphicsDevice.Viewport = player.PlayerCamera.ViewPort; GameRef.spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend, SamplerState.PointClamp, null, null, null, player.PlayerCamera.Transform); map.Draw(GameRef.spriteBatch); // Draw the Player player.Draw(GameRef.spriteBatch); // Draw UI screen elements GraphicsDevice.Viewport = Viewport; ControlManager.Draw(GameRef.spriteBatch); GameRef.spriteBatch.End(); } } the player's initialize and draw methods are like so internal void Initialize() { this.score = 0; this.angle = (float)(Math.PI * 0 / 180);//Start sprite at it's default rotation int width = utils.scaleInt(picture.Width, imageScale); int height = utils.scaleInt(picture.Height, imageScale); this.hitBox = new HitBox(new Vector2(centerPos.X - width / 2, centerPos.Y - height / 2), width, height, Color.Black, game.Window.ClientBounds); playerCamera.Initialize(); } #region Methods public void Draw(SpriteBatch spriteBatch) { //Console.WriteLine("Hitbox: X({0}),Y({1})", hitBox.Points[0].X, hitBox.Points[0].Y); //Console.WriteLine("Image: X({0}),Y({1})", centerPos.X, centerPos.Y); Vector2 orgin = new Vector2(picture.Width / 2, picture.Height / 2); hitBox.Draw(spriteBatch); utils.DrawCrosshair(spriteBatch, Position, game.Window.ClientBounds, Color.Red); spriteBatch.Draw(picture, Position, null, Color.White, angle, orgin, imageScale, SpriteEffects.None, 0.1f); } as I said I think I'm gonna need to do something with the render position but I'm to entirely sure what or how it would be elegant to say the least

  • 2D Collision in Canvas - Balls Overlapping When Velocity is High

    - by kushsolitary
    I am doing a simple experiment in canvas using Javascript in which some balls will be thrown on the screen with some initial velocity and then they will bounce on colliding with each other or with the walls. I managed to do the collision with walls perfectly but now the problem is with the collision with other balls. I am using the following code for it: //Check collision between two bodies function collides(b1, b2) { //Find the distance between their mid-points var dx = b1.x - b2.x, dy = b1.y - b2.y, dist = Math.round(Math.sqrt(dx*dx + dy*dy)); //Check if it is a collision if(dist <= (b1.r + b2.r)) { //Calculate the angles var angle = Math.atan2(dy, dx), sin = Math.sin(angle), cos = Math.cos(angle); //Calculate the old velocity components var v1x = b1.vx * cos, v2x = b2.vx * cos, v1y = b1.vy * sin, v2y = b2.vy * sin; //Calculate the new velocity components var vel1x = ((b1.m - b2.m) / (b1.m + b2.m)) * v1x + (2 * b2.m / (b1.m + b2.m)) * v2x, vel2x = (2 * b1.m / (b1.m + b2.m)) * v1x + ((b2.m - b1.m) / (b2.m + b1.m)) * v2x, vel1y = v1y, vel2y = v2y; //Set the new velocities b1.vx = vel1x; b2.vx = vel2x; b1.vy = vel1y; b2.vy = vel2y; } } You can see the experiment here. The problem is, some balls overlap each other and stick together while some of them rebound perfectly. I don't know what is causing this issue. Here's my balls object if that matters: function Ball() { //Random Positions this.x = 50 + Math.random() * W; this.y = 50 + Math.random() * H; //Random radii this.r = 15 + Math.random() * 30; this.m = this.r; //Random velocity components this.vx = 1 + Math.random() * 4; this.vy = 1 + Math.random() * 4; //Random shade of grey color this.c = Math.round(Math.random() * 200); this.draw = function() { ctx.beginPath(); ctx.fillStyle = "rgb(" + this.c + ", " + this.c + ", " + this.c + ")"; ctx.arc(this.x, this.y, this.r, 0, Math.PI*2, false); ctx.fill(); ctx.closePath(); } }

  • What's about Java?

    - by Silviu Turuga
    What is Java? In very short words, Java is a programming language that let you make an application that can be run on different operating systems, no matter we are talking about Windows, Mac OS, Linux or even embedded devices, such as RaspberryPi. When you compile a Java program, instead of getting a binary output as you get on other programming languages, you'll get a Java intermediate code, called Java bytecode. This is interpreted at run time, by a virtual machine that is specifically for the hardware and operating system you are using. What Java do i need? There are 5 major versions of Java: Java SE(Standard Edition) - this is what I'll use on most of my tutorials. Most of the examples will run on Java 6, but for others you'll need Java 7. Java EE (Enterprise Edition) - used for enterprise development Java ME (Micro Edition) - for running Java on mobile and different embedded devices such as PDAs, TV set-top boxes, printers, etc. Java Embedded - for some embedded devices such as Raspberry Pi, where the resources are limited JavaFX - to develop rich content User Interfaces. This is also something that will use a lot. More detailed information can be found on Oracle's website If you just want to run java applications you'll need the JRE (Java Runtime Environment) installed. If you want to program and create new applications, then you'll need the JDK (Java Development Kit).  How to check if Java is already installed? From command line, if you are on Windows, or from Terminal on Mac enter the following: java -version You should get something like this, if you have java installed on your system: java version "1.6.0_37" Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909) Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode) Note: your current Java version might be different from mine. More information https://www.java.com/en/download/faq/whatis_java.xml http://en.wikipedia.org/wiki/Java_(programming_language) Next steps Install Java SDK Chose an IDE. I recommend NetBeans as it is very easy to use and also let you quickly create the GUI of your application Alternatives are Eclipse, Komodo Edit (for Mac), etc. There are plenty of solutions both free or paid.

  • RPi and Java Embedded GPIO: It all begins with hardware

    - by hinkmond
    So, you want to connect low-level peripherals (like blinky-blinky LEDs) to your Raspberry Pi and use Java Embedded technology to program it, do you? You sick foolish masochist. No, just kidding! That's awesome! You've come to the right place. I'll step you though it. And, as with many embedded projects, it all begins with hardware. So, the first thing to do is to get acquainted with the GPIO header on your RPi board. A "header" just means a thingy with a bunch of pins sticking up from it where you can connect wires. See the the red box outline in the photo. Now, there are many ways to connect to that header outlined by the red box in the photo (which the RPi folks call the P1 header). One way is to use a breakout kit like the one at Adafruit. But, we'll just use jumper wires in this example. So, to connect jumper wires to the header you need a map of where to connect which wire. That's why you need to study the pinout in the photo. That's your map for connecting wires. But, as with many things in life, it's not all that simple. RPi folks have made things a little tricky. There are two revisions of the P1 header pinout. One for older boards (RPi boards made before Sep 2012), which is called Revision 1. And, one for those fancy 512MB boards that were shipped after Sep 2012, which is called Revision 2. So, first make sure which board you have: either you have the Model A or B with 128MB or 256MB built before Sep 2012 and you need to look at the pinout for Rev. 1, or you have the Model B with 512MB and need to look at Rev. 2. That's all you need for now. More to come... Hinkmond

  • LWJGL: Camera distance from image plane?

    - by Rogem
    Let me paste some code before I ask the question... public static void createWindow(int[] args) { try { Display.setFullscreen(false); DisplayMode d[] = Display.getAvailableDisplayModes(); for (int i = 0; i < d.length; i++) { if (d[i].getWidth() == args[0] && d[i].getHeight() == args[1] && d[i].getBitsPerPixel() == 32) { displayMode = d[i]; break; } } Display.setDisplayMode(displayMode); Display.create(); } catch (Exception e) { e.printStackTrace(); System.exit(0); } } public static void initGL() { GL11.glEnable(GL11.GL_TEXTURE_2D); GL11.glShadeModel(GL11.GL_SMOOTH); GL11.glClearColor(0.0f, 0.0f, 0.0f, 0.0f); GL11.glClearDepth(1.0); GL11.glEnable(GL11.GL_DEPTH_TEST); GL11.glDepthFunc(GL11.GL_LEQUAL); GL11.glMatrixMode(GL11.GL_PROJECTION); GL11.glLoadIdentity(); GLU.gluPerspective(45.0f, (float) displayMode.getWidth() / (float) displayMode.getHeight(), 0.1f, 100.0f); GL11.glMatrixMode(GL11.GL_MODELVIEW); GL11.glHint(GL11.GL_PERSPECTIVE_CORRECTION_HINT, GL11.GL_NICEST); } So, with the camera and screen setup out of the way, I can now ask the actual question: How do I know what the camera distance is from the image plane? I also would like to know what the angle between the image plane's center normal and a line drawn from the middle of one of the edges to the camera position is. This will be used to consequently draw a vector from the camera's position through the player's click-coordinates to determine the world coordinates they clicked (or could've clicked). Also, when I set the camera coordinates, do I set the coordinates of the camera or do I set the coordinates of the image plane? Thank you for your help. EDIT: So, I managed to solve how to calculate the distance of the camera... Here's the relevant code... private static float getScreenFOV(int dim) { if (dim == 0) { float dist = (float) Math.tan((Math.PI / 2 - Math.toRadians(FOV_Y))/2) * 0.5f; float FOV_X = 2 * (float) Math.atan(getScreenRatio() * 0.5f / dist); return FOV_X; } else if (dim == 1) { return FOV_Y; } return 0; } FOV_Y is the Field of View that one defines in gluPerspective (float fovy in javadoc). This seems to be (and would logically be) for the height of the screen. Now I just need to figure out how to calculate that vector.

  • Replacing latex with unicode symbols

    - by Elazar Leibovich
    Often, during a conversation or an email, or at a forum, I would like to type some math, but I don't need full equation support. Unicode symbols should suffice. What I need is an easy way to type math related unicode symbols. Since I already know latex, it makes sense to use the latex symbol mnemonics to type the math symbols. What I currently did is to write an AutoHotKey script which automatically replaces \latexSymbol with the corresponding unicode symbol, using the "hotstrings" AutoHotKey feautres. However, the AutoHotKey hotstrings proved unstable for many strings. Having a couple of tens lines would cause AHK to fail recognizing the strings from time to time. Any other solution? (No, Alt+unicode number isn't convenient enough) Attached is my AHK script. The PutUni function is taken from here. ::\infty:: PutUni("e2889e") return ::\sum:: PutUni("e28891") return ::\int:: PutUni("e288ab") return ::\pm:: PutUni("c2b1") return ::\alpha:: PutUni("c991") return ::\beta:: PutUni("c992") return ::\phi:: PutUni("c9b8") return ::\delta:: PutUni("ceb4") return ::\pi:: PutUni("cf80") return ::\omega:: PutUni("cf89") return ::\in:: PutUni("e28888") return ::\notin:: PutUni("e28889") return ::\iff:: PutUni("e28794") return ::\leq:: PutUni("e289a4") return ::\geq:: PutUni("e289a5") return ::\sqrt:: PutUni("e2889a") return ::\neq:: PutUni("e289a0") return ::\subset:: PutUni("e28a82") return ::\nsubset:: PutUni("e28a84") return ::\nsubseteq:: PutUni("e28a88") return ::\subseteq:: PutUni("e28a86") return ::\prod:: PutUni("e2888f") return ::\N:: PutUni("e28495") return

  • How do I use .htaccess conditional redirects for multiple domains?

    - by John
    I'm managing about 15 or so domains for a particular promotion. Each domain has specific redirects in place, as shown below. Rather than make 15 different .htaccess files that I would later have to manage separately, I'd like to use a single .htaccess file and use a symbolic link into each website's directory. The trouble is that, I can't figure out how to make the rules apply only for a specific domain. Every time I visit www.redirectsite2.com, it sends me to www.targetsite.com/search.html?state=PA&id=75, when it should instead be sending me to www.targetsite.com/search.html?state=NJ&id=68.

  • ADSL with RFC 2684 Bridging

    - by Axel Isouard
    My new ADSL line is now enabled, I can finally use my Netgear DM111Pv2 to use to the Internet. My ISP has told me a big surprise : I don't need to use a login and a password to connect to the Internet, then I must use the RFC 2684 bridging mode. It works pretty fine on the ADSL modem's side, but I've spent one night trying to figure out how to connect to the Internet through this modem. I only have a Fonera 2.0n and a computer running Gentoo Linux. I've been trying to use the br2684ctl utility with brctl on my Gentoo, first I've configured my kernel in that way : CONFIG_PPP=y CONFIG_PPP_BSDCOMP=y CONFIG_PPP_DEFLATE=y # CONFIG_PPP_FILTER is not set CONFIG_PPP_MPPE=y # CONFIG_PPP_MULTILINK is not set CONFIG_PPPOATM=y CONFIG_PPPOE=y CONFIG_PPP_ASYNC=y CONFIG_PPP_SYNC_TTY=y [...] CONFIG_ATM=y CONFIG_ATM_CLIP=y CONFIG_ATM_CLIP_NO_ICMP=y CONFIG_ATM_LANE=y CONFIG_ATM_MPOA=y CONFIG_ATM_BR2684=y # CONFIG_ATM_BR2684_IPFILTER is not set And I still get these messages : cirus nais # br2684ctl -b -c 0 -e 0 -a 8.35 br2684ctl[8041]: Interface "nas0" created sucessfully br2684ctl[8041]: Communicating over ATM 0.8.35, encapsulation: LLC br2684ctl[8041]: Fatal: failed to connect on socket; No such device The brctl utility keeps telling me "Invalid argument" each time I try to add the nas0 interface into my bridge, I'm honestly hoping I'm doing wrong. I've been following this README carefully and this tutorial on setting up a PPPoE connection with Gentoo, but the PPPoE interface just tries to start, and nothing special related to PPP happens, I can't see the interface when I do ifconfig. So, I'm asking you if there's something huge I've been missing since the beginning ! Maybe I should wait to buy a new router fully supporting the RFC2684 bridging mode, but I'm more interested in setting up this mode on my Fonera 2.0n and even my Raspberry Pi !

  • SeLinux blocking connection to sshd on Ubuntu 9.10

    - by Barton Chittenden
    When I try to log on to my laptop, which runs Ubuntu 9.10, the server rejects my login attempts. Checking /var/log/auth.log, I see the following: Feb 14 12:41:16 tiger-laptop sshd[6798]: error: ssh_selinux_getctxbyname: Failed to get default SELinux security context for tiger I googled for this, and ran across the following: http://www.spinics.net/lists/fedora-.../msg13049.html Here's the part that I think relates to the problem that I'm having: Quote: What's wrong on my system?

Maybe this code snippet from policy/modules/services/ssh.te is responsible for that: Allow ssh logins as sysadm_r:sysadm_t gen_tunable(ssh_sysadm_login, true) Any ideas? Do you have boolean init_upstart set to on? if not try setting it to on. I do not believe ssh_sysadm_login boolean works currently but i may be mistaken. -- Yeah, setting init_upstart to on did the trick! THANK A LOT! Do you know why this prevents the user from logging in through ssh even if selinux is set to permissive?? Ok, so the million dollar question is "where do I set 'init_upstart=1'"? It's not clear from context which configuration file needs to be edited, and I'm not at all familiar with SELinux configuration.

  • Laptop sleep: How to go into S3 easily?

    - by monov
    Laptop: Fujitsu-Siemens Amilo Pi-3525 OS: Vista When my laptop is plugged in and I close the lid, it goes into S1 sleep. This means that there is still: fan noise (annoying when trying to sleep at night) lots of power consumed (so if I then unplug the laptop and toss it in the bag, by the time I'm at school it's already drained and beeping ominously). What I want is S3 sleep, it solves both problems. I've found a roundabout way to go into S3 sleep: Unplug laptop Close lid (or click Sleep in Start menu) Plug laptop back in if needed The question: How do I force Windows to use always use S3 sleep when I close the lid? One thing I've tried is: dumppo admin minsleep=s3 (dumppo from here) Afterwards running just dumppo admin confirms that minsleep has been set, but closing the lid still goes into S1. Also, after a reboot, minsleep is reset to s1. I think dumppo is incompatible with Vista... MCE Standby Tool was recommended as a Vista-compatible alternative to dumppo, but it doesn't have any effect either. I looked in the BIOS settings, but there are no settings relating to ACPI sleeps/suspends there.

  • Replacing latex with unicode symbols

    - by Elazar Leibovich
    Often, during a conversation or an email, or at a forum, I would like to type some math, but I don't need full equation support. Unicode symbols should suffice. What I need is an easy way to type math related unicode symbols. Since I already know latex, it makes sense to use the latex symbol mnemonics to type the math symbols. What I currently did is to write an AutoHotKey script which automatically replaces \latexSymbol with the corresponding unicode symbol, using the "hotstrings" AutoHotKey feautres. However, the AutoHotKey hotstrings proved unstable for many strings. Having a couple of tens lines would cause AHK to fail recognizing the strings from time to time. Any other solution? (No, Alt+unicode number isn't convenient enough) Attached is my AHK script. The PutUni function is taken from here. ::\infty:: PutUni("e2889e") return ::\sum:: PutUni("e28891") return ::\int:: PutUni("e288ab") return ::\pm:: PutUni("c2b1") return ::\alpha:: PutUni("c991") return ::\beta:: PutUni("c992") return ::\phi:: PutUni("c9b8") return ::\delta:: PutUni("ceb4") return ::\pi:: PutUni("cf80") return ::\omega:: PutUni("cf89") return ::\in:: PutUni("e28888") return ::\notin:: PutUni("e28889") return ::\iff:: PutUni("e28794") return ::\leq:: PutUni("e289a4") return ::\geq:: PutUni("e289a5") return ::\sqrt:: PutUni("e2889a") return ::\neq:: PutUni("e289a0") return ::\subset:: PutUni("e28a82") return ::\nsubset:: PutUni("e28a84") return ::\nsubseteq:: PutUni("e28a88") return ::\subseteq:: PutUni("e28a86") return ::\prod:: PutUni("e2888f") return ::\N:: PutUni("e28495") return

  • Two parts: linux startup script to connect to bluetooth and cron to keep it connected

    - by D.R.
    I have a mini bluetooth keyboard and a Raspberry Pi running a Debian-based distro. I know the MAC address of the keyboard but for this question, let's just use AA:BB:CC:DD:EE:FF. Right now I have to have a wired keyboard connected as well as my bluetooth dongle for the mini-keyboard and on the wired keyboard, I have to run the following when the device boots up: sudo hidd --connect AA:BB:CC:DD:EE:FF If the device goes idle for too long, then the bluetooth disconnects and I have to pull out my wired keyboard and retype that same command. What I'm looking for it a way to have that command run at startup and a way to sense if it gets disconnected so that it will auto reconnect. The annoying thing is that they keyboard has to be in pairing mode (even though it has already been paired) when I run that command, otherwise it tells me the host is down. So perhaps the script needs to prevent it from disconnecting due to inactivity, otherwise I'll have to put it back in pairing mode to reconnect. So to recap: - A script to connect at startup (I can make sure to put the keyboard into pairing mode before turning it on) - A script to prevent it from disconnecting (maybe some sort of signal to send to it every 60 seconds or something?) Any help with this is greatly appreciated! StackOverflow is always the best place to find answers to weird questions! I've been searching long and hard for an answer, but finally had to resort to coming here! Thanks!

  • Piecing together low-powered hardware for an RS-232 terminal server

    - by Fred
    I'm working on reconstructing my Cisco lab for training/educational purposes and I found that the actual terminal server I have is dead. I have a couple of 8-port PCI serial cards which would be more than ample for my lab, but I don't want to leave my personal computer running to be able to access the console ports. Ideally I would access the terminal server remotely, either by SSH/RDP to the box (depending on what OS I go with) or by installing a software package that allows me to telnet directly to a serial port. I know I've found a program that does this under Linux in the past but its name escapes me at the moment. I'm thinking about scavenging for some old hardware, on eBay or something, to put together a low-powered PC. Needs to be something that: Has Low-power consumption Has at least 2 PCI slots (though I certainly wouldn't complain about having more) Has onboard Ethernet (or, if not, another PCI or ISA slot (not shared)) Can be headless once an OS installed (probably Linux) I'm currently leaning towards an old fashioned Pentium (sub-133MHz era) but I am wondering if anybody else knows of another platform/mobo that would suit these needs. Alternatively, I've been considering buying a Raspberry Pi and a big USB hub along with a bunch of USB-Serial adapters but this sounds like it'd get messy quick with cables and adapters all over the place, and I may not even have the same ttyS#'s between boots.

  • Debian can't connect to internet using LAN

    - by tampe125
    I have a headless Raspberry Pi using Debian Wheezy. I have a wifi dongle and if I connect my Raspberry using it, everything works fine: I can connect to the Internet, I can ping, I can update. However, if I get down my wifi and set up the lan interface, I lost my internet connection. I still can connect locally, using my laptop, but the connection doesn't exit (ie ping is not working).

  • Netgear router is not resolving hostnames

    - by Thomas Clayson
    Not sure what the problem is, but I am used to being able to access other clients on my LAN via their hostname. We got a new router from plusnet (Netgear WNR1000v3) and now this has stopped working. For instance, if I were to run a web server from one computer with the hostname TomPC usually I could go into a browser and type http://TomPC and I would get the web server front page. I can access it by using the LAN ip of the machine. e.g. http://192.168.1.1 works fine. I thought it would be a simple option in the admin panel of the router - possibly I had to turn on DNS/DCHP or something. But I can't see anything, and my searches on the internet seem to turn up ridiculous solutions involving setting up a dedicated DNS server on my LAN. This is just a small home network - really I just want to be able to access my Raspberry PI on the network without having to work out the IP address every time. (I know I could just set a static IP address for it, but using its hostname would be much easier). DCHP is enabled in the LAN settings part, although RIP is disabled (I don't know what the latter is) I don't know if this has anything to do with it? Many thanks!

  • What Media Extender / Centre Set up should I use?

    - by Bryn Hird
    I have installed cat6 throughout the house which I use for telephony and network. In my cellar I have a NAS Server, gigabit switch and I want to install a Media Centre to stream my video's, music, photo's and live TV (coax from the aerial to the cellar) over the cat6. Yeah I know I can get stuff on the internet but shared experience of watching TV as a family as it happens is a big plus for live TV. I'm aiming for 1080p. I want different users to be able to watch different channels. Max users = 4. I've played a little with Windows Media Centre, works fine with live TV. Likewise I have XBMC up and running with live TV. The issue I have is what do I put near the TV. I'd like a consistent user interface (grandma and the the other technophobes in the house are continually pestering me on how to use different TVs, change channel, inputs etc.) so a key part of this for me is to make the user experience the same and simple i.e. no keyboards / PCs hanging around the TV. I've just bought a Linksys DMA 2200 to test the Windows Media Centre, but obviously off eBay as they're a dying breed. And with Windows Media Centre removed from Microsoft plans such devices will get rarer. And as for 1080p, think I can forget it with that set up. I have tested XBOX 360, also works but ditto on Microsoft plans for WMC. I was thinking of a WD Live TV to test the XMBC setup. Now to the question. Any advice on Media Centre / Extender setups that will do the job as above and have some degree of futureproofing (building my own with my Raspberry PI is a last resort). I'd like to understand the standards involved in the futureproofing if anyone knows (DNLA, RVU etc.).

  • USB-to-Serial showing gibberish at 115200 Baud

    - by Mose
    I've got a serious problem which drives me crazy because I tried everything I could think of. First of all, I made a video: http://youtu.be/boghkuq7L_s but please read the following text for more information, not only view the video! When using a USB-to-Serial interface everything works as long as I don't go beyond 57600 Baud. At higher rates I only get giberish like this: év.­b0JNLYÆÿ¿iëd0U²(kßÞb! ú]/xscB!ï¯!BoXûÿ1ïâÖCÿ6ÌAnè*íÌC)º¿BíÞØ.C.@ÆÃwHJÂs "YE:ñ.èFðÌCÊ÷ÞÄ !x H w6@BtbHJ ̪ Ì6ì H¾a¿bH.">îvy®;f<ßBÌ p­L¨fæH­E ­þ¼MBÞI What makes the problem so strange is, I exchanged every component and the problem still presists. I tried differtent OSes (Ubuntu, WinXP, Win7, OSX 10.7) with 32 and 64 Bit. I tried USB-to-Serial interface from FTDI and Prolific. I tried reading the output from my Raspberry PI and from an Asterisk Appliance. I changed the cables and the wiring. Nothing helped. In the video I made a example with a old Notebook with native COM and put the USB-to-Serial to the same connection as "sniffer" (only Rx and GND connected) to make sure the output and everything is ok as one can see on the native port. The voltage is ok. Settings for both are 115200 Baud, 8 Bit with 1 Stop and no flow control. Native is ok. USB is messed up. I used the newest drivers and double checked all connections. I have no idea what is wrong here. As I couldn't find anyone describing problems like this I question my long experiance in computer science and think I'm doing some completly wrong... Please help :-/
