Using the milli() function in order to do accurate timing on the Arduino doesn’t work because it shares the same priority in code execution as any other code. I wrote a blog post that talks about using PWM and an interrupt in order to create a much more accurate clock. In my post I talk about how to wire the PWM to the interrupt and how to use the Adafruit 2.2 inch TFT LCD to display the time. The full post with pics, links and demo code is here:

I also recorded a video of it in action:

My latest demo video of the IR Cam Headtracker:

This is actually not the latest version of the controller software.  I have made a few revisions since posting this on youtube that eliminates some of the jerky movements and gets rid of all the mismatched Bytes (coming from the camera).  The end results is a lot smoother than you see here.  Right now I am working on putting the Max Power IR LED’s into the headset in the hopes that I can extend the distance between the headset and the camer (right now my max distance is ~1 meter, and i need it to work as well at 2 meteres for larger TV’s).

Got the gainspan wifi breakout the other day. I am planning on using a simple serial connection with it to post my humidor data to a webservice (maybe pachube.com for now). had some initial issues with the serial communication but that started with me having the wrong docs and attempting to issue commends for a different device 🙂

Now it seems to be making sense and I am able to see external Wifi routers in my neighborhood. I can see why google used them for approximate positioning, since they all have a unique value associated.  Havent quite connected to one yet, but I just havent gotten that far. Want to make sure that I have a clear understanding of how this thing works before I move into uncharted territory.

The Saleae Logic Analyzer has been critical here. It allows me to see the serial data down to the byte level and can even interpret the data, so I know what these devices are actually saying.  Its almost like a 2-way debug, but at a much deeper level.

And I must say its pretty awesome, seems unthinkable how fast these things work. The logic me to see the data, capture and measured

Welcome to my FEZ Domino Project blog.  I will be regularly posting updates to the FEZ projects I will be working on.  Right now I am concentrating on the Compass module to give my final FEZ Pathfinder a sense of direction.  Look here for more information and code examples:
