Quick tech demo

Hell everyone, here is a short tease of what I've been working on. It demonstrate a sample Xbox 360 XNA project pulling data from a wii-remote. As demoed in the video, it can read the buttons, IR locations, and the motion data. Too bad that the process is very slow due to a couple of limitations. It can roughly read the data 5 times per second. This causes the lag in the videdo. Maybe I can improve the speed when more MS expands XNA's API library and/or tools capability. Won't it be cool to use wii-motes on the XBox 360? Now that I have access to retrieve data from outside the box, there are more interesting things I can do... As the next demo will show. ;)

XNA project progress...

Quick update on my XNA project (problems with short attention span?)
  • side tracked to look at different modelling program
  • side tracked to look at Google's 3D ware house
  • played with Sketchup
  • side tracked to look at Google MAP API, KML
  • finally found a model I wanted, and converted to the format XNA likes
  • diddling with XNA's 3D rotations
  • learned what a Gimbal Lock is (doh!)
  • learned more about quaternion and how to use it

Finally, at this point, have a model that rotates (yaw, pitch and roll) on its own axis. I think it's time to polish up that Linear Algebra book from last millenium...

How a typo gets around the world...

So, in a previous post, I mentioned that this blog was linked by Engadget. Turns out that Engadget folks made a typo (used a "t" instead a "s" in the domain name). I have asked them to correct the typo since. The term "waru360" is new and unique, so it's easy to keep track of the typo on google. It is interesting to see how far the typo has travelled. It first turned up on SWik, and then Zimbio (food and wine portal?), and now on a Japanese site. These reminds me of what happens when you have your identity stolen. The misinformation just propagates itself and gets harder and hard to correct... This will probably diminish after the the correct spelling shows up in more places.

We are famous!

I send a tip off to Engadget earlier today regarding Wii's mod chip issues and they linked this blog in the article! If you are checking out this site from Engadget, welcome. :) But there isn't really anything to see here yet... Come back later if you are intested in Xbox 360, XNA or home brew.

The Beginning...

Too lazy to start yet another site and install yet another php/mysql/blog-engine of the day, so I decided to keep all XNA programming related stuff on for now. We will see how well it goes. Thanks for dropping by!
