Recent Projects Rollup

A few things I’ve worked on or written have gone up in the past couple of months, so here’s a quick list of what they are and where you can get them:

Kinect Service v1.6

Download

The Coding4Fun Kinect Service allows you to stream Kinect color, depth, skeleton, and audio from one PC to another PC or a Windows Phone via sockets. This new release now includes Windows Runtime Components written in C++ which target x86, x64 and ARM. Now you can stream Kinect data to a Windows Store app!

Maelstrom

eb2a8836-cf09-473e-a2a4-25640aaf5781

For //build/ 2012, us Coding4Fun folks wanted to showcase what Windows 8 can offer developers. There are a lot of projects showing off great things like contracts and Live Tiles, but we wanted to show off some of the lesser known features. This project focuses on one of those: stereoscopic 3D with DirectX 11.1. Imagine ridiculously over-engineered 3D pong, and that’s Maelstrom!

MJPEG Decoder v1.2

The latest release of my MJPEG …

Dan Fernandez and I will also be giving a talk on Kinect goodness.  Here are the details:

Coding4Fun: Build Fun, Cool, Commercial Applications Using the Kinect for Windows SDK

Session Code: DEV330
Speaker(s): Brian Peek, Dan Fernandez
Tuesday, June 12 at 5:00 PM - 6:15 PM in S320A

Come to this must-see session to find out how you can use the Kinect for Windows SDK to build commercial applications! Learn how the RGB and depth cameras work, how to use and fine-tune skeletal tracking, how to read an audio stream from the Kinect microphone array and even how to send Kinect data over the network including to your Windows Phone

This same session will be given at TechEd Europe in two weeks, with Clint Rutkas playing the part of me.  I will not be at the Europe conference.

So, if you're attending …

Joining the Mothership

imageAt long last I have accepted a full-time position at Microsoft, working on the Channel 9 team, mainly doing Coding4Fun stuffs.  I'll be telecommuting from NY as I have been these past 8 years.  It's hard for me to believe that I've been doing Coding4Fun articles and projects for the team since 2006, but I'm excited that I now get to do it full-time.

Also joining the team is master UX-man Rick Barraza.  He brings a pile of amazing talent and skill that will really allow us to create some fantastic projects.  And, of course, we're joining the existing team of Dan Fernandez and Clint Rutkas, with Greg Duncan heading up the Coding4Fun blog and Kinect Project blog.

Also note that Coding4Fun is looking for a junior developer/program manager.  So, if you want to join the team, now's your chance!

Anyway, I'm very excited to be joining Microsoft, and I'm really looking forward to seeing what we can crank out as a team…

Kinect for Windows SDK is here!

image

Hooray!  I can finally talk about this!  As I've alluded to previously, I had a hand (one of many) in the managed portion of the SDK and what was originally shown at MIX. Since then the SDK has changed a bit but it's finally ready to go!

The Kinect for Windows SDK is now available for download on the Microsoft Research site.  We have also launched several samples over at Coding4Fun that you can begin using immediately:

Coding4Fun Kinect Toolkit

You definitely want to download this one when you get started.  This toolkit contains a variety of extension methods and controls to make using the Kinect for Windows SDK even easier to use.  Some of my code appears in this one.  Smile

Kinect Mouse Cursor

This sample is entirely mine.  Kinect Mouse Cursor is a demo application that uses the Kinect for Windows SDK and its skeletal tracking features to allow a user to use their hands to control the Windows mouse cursor.  Use your right hand to move the …

MJPEG Decoder v1.1

A quick update to my Motion JPEG Decoder is now available at CodePlex.  Version 1.1 adds the ability to specify username/password credentials for cameras that require a login.  For example:

MjpegDecoder _mjpeg;

_mjpeg = new MjpegDecoder();
_mjpeg.FrameReady += mjpeg_FrameReady;

_mjpeg.ParseStream(new Uri("http://192.168.2.200/img/video.mjpeg"), "user", "password");

As always, questions/comments welcome.  Enjoy!

MIX11

imageIt's almost time for another MIX conference! Once again I'll be there with the Coding4Fun crew showing off some spiffy new projects for attendees to play around with, along with a few other surprises. I'll also be taking part in John Papa's Open Source Fest on Monday evening, demonstrating WiimoteLib and my MJPEG Decoder.

Anyone else heading to the conference? If you are, be sure to stop by the Coding4Fun area in the Connect Lounge and say hello, and stop by the Open Source Fest on Monday night to take a look at over 50 great open source projects and vote for your favorites. I'd say I'd trade drinks for votes, but those are free, too.

And finally, if anyone attending is working on a fun or interesting project and would like to do an interview for my Coding4Fun Show on Channel 9, please let me know.  Almost anything goes, so I'd love to see what everyone out there is working on.

Hope to see you there!

MJPEG Decoder

209653324My latest article and library is now live on the brand new Coding4Fun site, now on Channel 9, and over at CodePlex.  This project allows you to very easily decode a MJPEG (Motion JPEG) stream from a network camera (or any other source) into a consumable type for WinForms, WPF, Silverlight, XNA and Windows Phone 7 (both Silverlight and XNA).

The MJPEG Decoder library started life as a project for the t-shirt cannon built for the MIX10 keynote.  The original plan was to have an IP camera attached to the robot for a real-time video stream from the bot's perspective, but the feature wound up being cut for time, and due to some issues rendering the video on the very early Windows Phone 7 tools.  The library has been sitting around a while, has gone through several rewrites and now supports almost every platform I can think of.  With the new Coding4Fun up and running, it was time to polish it off and get it posted.

Take a look at the article, download the binaries and …

TweeVo v1.1 Released!

A new version of TweeVo is finally available.  This version allows the program to work once again now that Twitter has switched over to a mandatory OAuth/xAuth authentication scheme.  Chris Miller deserves all the credit for this one for handling the implementation of the new security scheme with some sample code from Shannon Whitley.  You can find downloads over on the original TweeVo page.  Give it a try and let me know if you run into any issues making it go.  Enjoy!

VSLive Devapalooza and Jeopardy on Coding4Fun

imageTonight I hosted the Devapalooza event for Visual Studio Live in Redmond.  For the event, we played a Jeopardy-like game using software and hardware I created.  You can find an article on how the software was created, how to build the hardware, and full source/binary downloads over at Coding4Fun and CodePlex  This can be a fun way to host training at your office, or a way to liven up a user group.

A huge thanks to Dan Waters and Clemens Vasters from Microsoft, VSLive speakers Rocky Lhotka, Deborah Kurata, and David Platt, and our three attendees who played the game.  I think it was a great time.  Hopefully you did too if you were in attendance.

After playing the game tonight for real, I have a few ways to fix up the software and make it a bit easier to use, especially on the scoring side.  Also note that the code isn’t the best example of great coding.  With this being a side project and the deadline looming, I took a few dirty shortcuts.  But, …

VSLive! Redmond 2010

n190107439474_2070I have been selected to speak at this year’s VSLive! conference on the Microsoft Campus in Redmond.  I’m very excited about this conference for a couple of reasons.  First, it’s on campus, which will allow me to get together with my Coding4Fun/Channel 9  friends to do some planning.  Secondly, VSLive! attendees are also allowed to spend some of their own cash at the Microsoft store.  And finally, in addition to presenting two sessions at the conference, I’m also coordinating a special event on Wednesday night which we’re calling Devopalozza.  I am creating a team Jeopardy! style game-show which will pit Microsoft Speakers against VSLive! Speakers against VSLive! Attendees.  I’m currently creating both hardware and software to drive the game, which will later turn into an article on Coding4Fun for those that might want to create a game-show at home or the office.  And, I’ll even be hosting the show at the event.

    WiimoteLib Future

    image I’ve been working on a version 2.0 of WiimoteLib which reorganizes the library quite a bit to clean up the codebase.  It’s not quite ready for release, and I don’t have an ETA currently, but I wanted to note some of the changes and get some feedback as I finish things up.

    • I will be including a VS2010 solution for the project in addition to the original VS2008 solution
    • I’m hoping to have support for both sound and the WiiMotion Plus extension completed
    • Support for the Taiko Drum and DJ Hero turntable (testers welcome for the DJ Hero turntable)
    • Extensions have been broken out into separate classes so their code is self contained:
      • image
      • All extensions inherit from ExtensionController
      • All state objects for extensions implement the IExtensionState interface
      • Here’s an example of the new Nunchuk class.  As you can see, everything related to the Nunchuk is located in this class:

    ThinkGearNET Library

    mindset I have written and posted a new library that allows .NET developers to easily connect to and use the Neurosky MindSet headset from any .NET application.  You can find the source code and a binary of the library at CodePlex.  Usage is very simple and may seem familiar to those that have used my .NET Wiimote LIbrary; set a reference to the library and you can connect to a headset as follows:

    private ThinkGearWrapper _thinkGearWrapper = new ThinkGearWrapper();
     
    private void Connect()
    {
        _thinkGearWrapper = new ThinkGearWrapper();
        
        // setup the event
        _thinkGearWrapper.ThinkGearChanged += _thinkGearWrapper_ThinkGearChanged;
        
        // connect to the device on the specified COM port at 57600 baud
        _thinkGearWrapper.Connect("COM4", 57600, true);
    }
     
    void _thinkGearWrapper_ThinkGearChanged(object sender, ThinkGearChangedEventArgs e)
    {
        // write out one of the many properties
        Debug.WriteLine("Attention: " + e.ThinkGearState.Attention;

    Before and AfterPDC 2009, starting November 17th, is almost upon us and I’ll be heading out to the conference once again with my Coding4Fun/Channel 9 playmates.  Anyone else heading out to the big show?

    We won’t be doing a Coding4Fun session like we did last year, but I will have another fun project for people to check out in the Coding4Fun area.  I can’t give out details until after the show begins, but you can probably guess there is a Wiimote in the mix somewhere.  And some spiffy new hardware.  And maybe some XNA.  Look for the details here after the show, and an article with full source code shortly thereafter.

    We also have 4 or 5 other developers with their latest and greatest projects, all of which are nothing short of incredible and put mine to shame.  I will likely be doing a compendium Coding4Fun Show with all of this year’s project authors so those not in attendance can see their incredible work.

      WiimoteLib 1.8 Beta 1 Posted

      image I have posted a new version of WiimoteLib as a beta for people to play around with the Wii MotionPlus accessory.  Please note that this is not a stable release and should only be used if you wish to mess around with the MotionPlus.  Also note that only C# source code is included in this release as it is not a final build.  Here’s the change log:

      v1.8.0.0

      • Taiko Drum Master's TaTaCon drum controller supported (Dean Herbert)
      • Bare-bones Wii MotionPlus support (wiibrew.org, testing by Tyler Tolley)
      • WiimoteTest UI changed to add MotionPlus data
        • Please note that the current version is VERY flakey and may not work at all for you.
        • Pair your Wiimote, plug in your MotionPlus, call InitializeMotionPlus()
        • Extensions plugged into the MotionPlus will give wacky results...not supported...yet!
        • Internal changes to perhaps fix some threading issues

      So remember, it’s a beta, it may not work for you, and the data you’ll get back from the accessory is …

      Status of Wii MotionPlus Support for WiimoteLib

      Update: See this post for a beta release

      wii-motionplus Ok, I get about 10 emails a day on this, so I figure a status update is in order.

      The Wii MotionPlus extension for the Wiimote was released last week.  Since then, I and others have been working to figure out how the device works.  Unfortunately, it does NOT work as every other extension controller has worked up until this point, mostly due to the fact that the Wii MotionPlus accessory has an expansion port of its own so all of the other extension controllers can plug into it.

      In the past few days, some progress has been made thanks to the folks over at wiibrew.org, although functionality is nowhere near complete.  For example, it’s currently impossible to have the Wiimote notify you when the Wii MotionPlus is inserted into the bottom of the Wiimote, like all of the other extension controllers do.

      I have been working with the information at wiibrew.org and am trying to get things working reliably with my library so that …

      WiimoteLib v1.7 Released

      image I have just put up the latest version of WiimoteLib at CodePlex.  The changes for this release are:

      v1.7.0.0

      • Writing registers is now properly waiting for the Wiimote to reply before continuing...this removes all of the Thread.Sleep() calls and should *greatly* improve performance when setting LEDs and rumble (Serial Nightmare & wwibrew.org)
      • Guitar Hero: World Tour Guitar and Drums now properly recognized and used (wiibrew.org, tested by Tyler Tolley and Mauro Milazzo)
      • Guitar whammy bar is now a 5-bit value instead of 4 (wiibrew.org)
      • Position of 4 IRs now properly reported in Basic reporting mode (Dan Carter)
      • Found1/2 now properly reported in MSRS (reported by akka243)
      • MSRS project updated to Microsoft Robotics Developer Studio 2008

      WiiEarthVR Article and Source Code Posted

      I previously talked about my WiiEarthVR project shown at PDC project, and now I have posted the article for the application up at the Coding4Fun site.  Full source code is available.  You’ll need some hardware to make this go, namely a Wiimote, Nunchuk, Wii Fit Balance Board and a pair of Vuzix VR920 glasses, but the hardware can be toggled on or off depending on your own setup.  The VR920 glasses are pretty cool in that they also work with a variety of FPS games on your PC with a custom driver they include.

      The article will, among other things, teach you how to use Virtual Earth 3D from a managed host (i.e. a WinForms app, not a web page), how to talk to the Wiimote, Nunchuk and Wii Fit Balance Board, how to retrieve the head tracking data from the VR920 glasses from .NET, and how to draw stereoscopic 3D images to the VR920 glasses from .NET.  Quite a bit packed in there…

      Anyway, have a read and, as always, questions and comments are welcome.

      image A new version of my managed Wiimote library for .NET has been released.  You can find version 1.6 up at CodePlex now.  The changes are as follows:

      v1.6.0.0

      • Added "center of gravity" calculation to the Wii Fit Balance Board (thanks to Steven Battersby)
      • Structs are now marked [Serializable] (suggested by Caio)
      • Battery property is now a float containing the calculated percentage of battery remaining
      • BatteryRaw is the byte value that used to be stored in the Battery property
      • WiimoteTest app now reads extensions properly when inserted at startup
      • Exposed HID device path in new HIDDevicePath property on Wiimote object
      • Changed the time delay on writes to 50ms from 100ms...this should improve responsiveness of setting LEDs and rumble

      I feel like I’m running out of things to implement and bugs to fix.  I know that’s not true.  So, I want to hear from the people using my library…

      What features/bugs do you want to see …

      TL39: Coding4Fun: Windows Presentation Foundation Animation, YouTube, iTunes, Twitter, and Nintendo's Wiimote

      image Well, PDC2008 is over.  I had a lot of fun, met a ton of interesting and fun people, and learned about a lot of exciting new technologies.  I hope to make it back out there next year.

      Our PDC2008 session video has been posted up at Channel 9 along with the PowerPoint slide deck.  In this session you will learn about four of our current projects:  WiiEarthVR by myself, InnerTube by Dan Fernandez, TwitterVote by Clint Rutkas and BabySmash by Scott Hanselman.

      If you’d like to check out the video, you can watch it “live” or download the deck and video in various formats with the following links:

      Source code for all projects will be available soon and I’ll provide an update when it’s available.  WiiEarthVR will also have its own Coding4Fun article within a week or two.  InnerTube and TwitterVote are also featured in depth in our new book, “Coding4Fun: 10 …

      WiiEarthVR at PDC

      Update 1/20/09: Here’s a vid from Channel9 showing the WiiEarthVR project:

       

      Time to talk a little bit about my PDC demo…

      About a year ago, I wrote an application to control Virtual Earth 3D with the Wiimote named WiiEarth and a corresponding Coding4Fun articleon how it was done.  Since that time VE3D has been updated several times and code changes have broken my application.  Since their API is undocumented and unsupported, it was bound to happen.

      For PDC this year, I decided to write a new version of WiiEarth, now named WiiEarthVR, using the Wiimote and some additional hardware, namely the Wii Fit Balance Board and a pair of Vuzix VR920 glasses.  Using the Balance Board, the user can shift their center of gravity (i.e. lean) and control the VE3D environment as if they were on a hovering glider.

      Wii Fit Balance Board VR920

      The VR920 glasses contain sensors to allow head tracking in 3 degrees of freedom.  A very simple API provides a way to determine the yaw, pitch and …

      PDC2008

      pdc Anyone heading out to PDC2008 this year?  I will be in attendance with (hopefully!) a new Wiimote project and perhaps a few old ones as well.  More details on that when the project is a tiny bit further.  We will also be giving away a free chapter of our new book “Coding4Fun: 10 .NET Programming Projects for Wiimote, YouTube, World of Warcraft, and More” to lucky PDC attendees at the O'Reilly booth.

      I will also be co-presenting a lunch session at PDC:

      Title: Coding4Fun: Windows Presentation Foundation Animation, YouTube, iTunes, Twitter, and Nintendo's Wiimote
      Date/Time: Tuesday, October 28th, 12:45pm-1:30pm
      Speakers: Dan Fernandez, Scott Hanselman, Brian Peek, Clint Rutkas
      Room: 403AB
      Abstract: Spend time with Coding4Fun authors as they walk through some DIY Development projects: TwitterVote, Wiimote, InnerTube, and BabySmash.

      You can add this session to your agenda by visiting the PDC site and searching for “Coding4Fun”.

      SQL Server 2008, Visual Studio 2008 SP1 and Visual Studio 2008 Express

      I ran into a bit of weirdness yesterday when trying to install SQL Server 2008.  I have Visual Studio 2008 installed as well as a couple of the Visual Studio 2008 Express products (for testing solutions for the Coding4Fun site and the upcoming book).  I installed Visual Studio 2008 SP1 and all went as planned.  After looking at the Help –> About screens, Visual Studio and all of the Express products showed the proper version tag:  9.030729.1 SP1.  So I figured all the products were updated and good to go.

      Next I tried to install SQL Server 2008 and got an error stating Rule “Previous releases of Microsoft Visual Studio 2008” failed.  I re-installed SP1 figuring something had gone wrong, but no dice.  After digging through the SQL Server 2008 install logs I realized what was happening.  The installer was using the HKLM\SOFTWARE\Microsoft\DevDiv\XXX\Servicing\9.0\SP keys to determine if SP1 had been installed and the registry settings were set …

      WiimoteLib v1.5.2 Released

      Sorry for all of the previous confusion.  Version 1.5.2 is now up at CodePlex.  This release now has the Wii Fit Balance Board working for everyone who has tried it.  Please let me know if you have any issues with it.  The changes:

      v1.5.2.0

      • Ok, Balance Board support is really fixed this time (thanks to Manuel Schroeder, Eduard Kujit and Alex Wilkinson for testing)
      • LED checkboxes are properly set on the WiimoteTest tabs

      Enjoy! Read More

      WiimoteLib v1.5.1 Released

      UPDATE 2: Sorry, but I've removed this release from CodePlex.  It's just too buggy (though it continues to work just fine for me).  Look for version 1.5.2 very soon...

      UPDATE:  It appears some people are still having issues with this build as well due to some Balance Boards being a bit finicky in their response times.  Stay tuned for build 1.5.2 soon…

      Oops.  Apparently the one new thing in version 1.5, Balance Board support, was actually broken.  I have just put version 1.5.1 up at CodePlex which fixes the Balance Board operation.  Sorry about that…

      WiimoteLib v1.5 Released

      Wii-Balance-Board-1I’m really cranking out the releases these days.  Today I have released WiimoteLib v1.5 at CodePlex.  The big news is that the Wii Fit Balance Board is now supported.  The balance board is simply a very heavy piece of plastic with 4 weight sensors located at the corners.  The library reads those individual sensors to determine how much weight is applied to each sensor, and the total weight applied to the entire board.  You can use it as an impromptu (and very expensive) scale.

      Comments and bugs welcome…

      WiimoteLib v1.4 Released

      In an effort to put out more frequent builds with fewer changes, I’ve released WiimoteLib v1.4 to CodePlex.  This release contains the single most requested feature:  multiple Wiimote support.  I’m very interested to hear bug reports and suggestions on this release, so please do let me know how it works for you.  The original Coding4Fun article has also been updated with some details on how to use multiple Wiimotes, as has the WiimoteTest application included with the distribution.

      Changes

      • Multiple Wiimotes supported!
      • Slight change to ExtensionType enum for better extension detection
      • Decided I didn't like the dependency on System.Drawing for the 2D point so am now using my own Point structs.  Sorry...
      • WiimoteTest app updated to show multiple Wiimotes working

      WiimoteLib v1.3 Released

      Time for another WiimoteLib release!  You'll find the new version in the usual place at CodePlex.  What's new you ask?  Why, check out this list:

      • All projects updated to Visual Studio 2008 format
      • SetReportType contains an overload taking a new IRSensitivity parameter which will set the IR camera sensitivity when using an IR report type
      • Created new WiimoteException type which is now thrown by the library
      • Moved InputReport enum to namespace level
      • Events now using the generic EventHandler class instead of custom delegates
      • Refactored the state structures to use Point/PointF and my own Point3/Point3F
      • Refactored IR sensors to be an array
      • Added support for the Guitar Hero controller (tested by Matthias Shapiro, Evan Jacovier)
      • Test app will run without Wiimote connected (Andrea Leganza)
      • ReadData now returns the proper amount of data for requests of more than 16 bytes (reported by David Hawley)
      • Test application updated with above changes
      • Lots of breaking changes, but the survey …

      Silence...

      Where have I been?

      Sadly, nowhere good.

      My father passed away extremely unexpectedly on March 4, 2008 and life has been hectic and chaotic ever since.  I'm finally back into some sort of routine, so it's time to update here and explain what's going on outside of the unpleasantness.

      First off, I've been contracted to co-author a book for O'Reilly (tentatively) titled Coding4Fun with Dan Fernandez from Microsoft.  The book will be a compendium of 10 (give or take) projects that, as the title suggests, combine fun and coding.  I'll update as we go through the process.

      Secondly, I'll be presenting a session titled Introduction to Microsoft Robotics Studio with Lego NXT at the Tech Valley Code Camp this Saturday, April 19th.  If you're in the area, as always, stop by.  It should be a fun and informative day.

      And finally, I will be back to work on some Wiimote goodness soon.  I was right in the middle of Guitar Hero controller support when the above …

      WiimoteLib Survey

      Update:  Wow!  In just over a week I reached Survey Monkey's limit of 100 responses for the survey.  I'll be posting results soon.  Thanks to everyone who took the time to give me their feedback!

      For those of you that use my Managed Wiimote Library (and if you're not, why aren't you?), I've put together a very short, 3 question survey to gather some opinions on how to move forward with upcoming releases.  Please take the 30 seconds to click responses to the 3 multiple choice questions and let me know how you'd like to see the library evolve.  Thanks!

      Yet Even More .NET-based Wiimote Applications

      In the past couple of weeks, several very interesting projects using my Managed Library for Nintendo's Wiimote have appeared.

      First off, Johnny Chung Lee has created some amazing and unique user interface demos with the library which can be found at his site.  Here are a few videos showing off what he's done:

       


      Wiimote Whiteboard

       


      Head Tracking Display

       

      Cynergy Labs has used the library in conjunction with WPF and some of Johnny's ideas to create a Minority Report-style interface with some Microsoft Surface-style effects:

       

      Incredible stuff.  I'd also like to toot my own horn and state that, at the time of this writing, my Wiimote library is the #1 most downloaded project at CodePlex.  I wish I could take credit for that, but I'm certain these talented folks and their amazing work with the library are the reason for that.

      As always, if anyone out there is using the library, please contact me so I can add you to the master list.

      Animated Musical Holiday Light Show - Version 2.0

      I finished this a bit later than I wanted to, but a brand new version of my Light Sequencer application and article is now available at Coding4Fun.  You may recall my previous article on creating a musical light show for the holidays.  If not, here's the video showing the output:

      New Features for 2.0

      • MIDI support
        • Load a MIDI file and a sequence will be automatically created based on the data contained in the file.  You can automatically create your own show with barely any effort at all!
      • Playlists
        • Load up several sequences and have them play in order to create a multi-song show!
      • More accurate timing
        • The timing algorithm used in the last version was very imprecise...it worked, but it wasn't perfect.  The new version uses a method which gives millisecond precision timing
      • Cut/Copy/Paste
        • One can now cut/copy/paste cells on the grid...makes it easy to repeat chunks of sequences without having to tap out the rhythm by hand over and over again
      • Edit existing …

      Coding4Fun Article Ideas

      If you visit my site, you're likely here because of an article I wrote on Microsoft's Coding4Fun site.  Or perhaps someone doesn't like you and punished you with a link to my blog.  Assuming the former, I am continuing to write articles on topics that are fun and/or interesting for me, but I wonder what the readers find fun and/or interesting.  So, with that in mind, do you have ideas for a future article?

      If you have any ideas, I'd love to hear about them!  Please feel free to leave ideas as a comment on this article, a post in this general forum thread (easier for discussion), or contact me directly.  Coding4Fun is a Microsoft site that is geared toward development in .NET using the free Visual Studio Express products, so please keep that in mind when offering suggestions.

      I look forward to hearing what you readers would like to learn about.

      Thanks!

      Wiimote Library Update

      Finally!  I have updated my Wiimote library with quite a few bug fixes and a few new features.  Here are the important links:

      Starting with this version (v1.2), the library is licensed under the Ms-PL.  This will likely change nothing for 99% of you, but be sure to read through the license before redistributing your applications compiled against this new version.

      The new version also includes a CHM help file for the entire API.  For now, the C4F article will remain the source for the basics, and the CHM will remain up-to-date with each release of the API itself.  Hopefully that will be able to provide some more detailed information than the base article, though the API itself isn't very complex.

      And finally, here's a list of things that changed since v1.1 .  Note that this list may not be 100% complete as I was a bit lax in keeping my changes noted.

      WiiEarth -- Wiimote Interface for Virtual Earth

      Long time no blog.

      My latest article is up at Coding4Fun.  This time I created a Wiimote interface for Virtual Earth 3D.  You can now drive around Virtual Earth like you're playing a first-person shooter on the Wii.  I think it's fun.  Hopefully you will too.  Here is a video of the demo in motion:

      As always, full source code provided.  Give it a try and let me know what you think!

      Additionally, I'll have a new version of my Wiimote library up in the next day or three.  Check back for more details...

      Outlook Webmail Add-in for Windows Home Server

      My latest article is posted to Coding4Fun.  This time, I wrote an add-in for Windows Home Server that allows one to view their email stored in Outlook via the web.  Perhaps I'm the only one, but I have 6 or 7 email accounts all of which POP into Outlook.  Hardly any of them support IMAP or have a webmail interface.  When I'm away from home and want to check my messages, either I have to remote desktop into my home machine and use Outlook that way, or I need to remember to shut down outlook, and then check all accounts separately.  With this add-in, I can now view my Outlook messages via a web browser.

      I'm doing something a little different with this article by offering the source code and binaries via CodePlex.  My hope is that you folks out there might find a use for this and decide to extend it.  Hopefully CodePlex will make that process easier.

      Check out the article and, as always, comments and questions welcome!

      Head Banger

      XNAiconBack in May, I posted about my involvement in Maker Faire 2007.  For one of my projects, myself and several friends, collectively known as Ganksoft Entertainment, created a game from scratch using the Microsoft XNA Framework and Game Studio Express called Head Banger.  It's a rhythm-based music game in the vein of Dance Dance Revolution (DDR) and Guitar Hero.  If you are a fan of either game, or the genre in general, you'll likely enjoy what we've created.  I have posted the game up to our website in both Windows and Xbox 360 flavors.  Sometime soon I will be writing an article that will appear on Coding4Fun on how the game was created along with the full source code of the game.

      Wiimote Applications

      I've received a couple emails in the past week of people using my Managed Wiimote Library to do some spiffy things.

      Brent Rossen's project allows one to interact with a virtual patient and is described as:

      This project was primarily created to allow the Wiimote to be used as a novel interface for a virtual environment. The goals were to create a Wiimote server, allow interaction with a virtual environment, and provide haptic as well as audio feedback. Six degrees of viewing freedom and stereo vision are provided via a Head Mounted Display and optical tracking system. Sound is provided through FMOD. Much of this project is built on top of code from the Virtual Patient Project.

      Evan Merz has created a virtual drum kit available at his site along with a video showing its operation.

      Great stuff, guys.  Anyone else using my library for a project?  I'd love to hear about it!

      Today, someone sent me a video of what is undoubtedly one of the coolest things I have ever seen.  If you are a regular reader, I'm sure you recall my Animated Christmas Lights article at Coding4Fun and accompanying video.  Today, I received a video of someone using my software and Phidget boards to animate something other than lights.  If you've ever been to a Chuck E. Cheese, you may recall one of the animated characters known as "The King" (photo from http://sp-com.tripod.com/):

       

      I have been told that The King shown in the video below was broken and left for dead.  After being salvaged from a dumpster, he was carefully repaired and restored, and once again animated and set to music using my Light Sequencer application normally used for Christmas lights!  I distinctly remember The King at my local …
