Hi everyone,
Abdelrazak's comments reminded me of my hobby interests in GPS and  
accelerometers[1].  By day, I work for OSGeo helping day-to-day  
admin, marketing, promotion and more.  I'm a long time open source  
fan, particularly in geospatial applications like MapServer, GDAL/ 
OGR, PostGIS.  I wrote about them in my book.[2]

But sometimes at night I break out the soldering iron and my Arduino  
prototyping board[3] and interface it to my GPS receiver,  
accelerometers (in a game controller) and digital compass chip.  Then  
I pump them into the 3D globe viewer, OSSIMPlanet.[4]

I'm at the point where (I think) I need to learn more about  
"navigation algorithms", such as Kalman filters, etc.  So I can merge  
my inputs into something useful and less jittery than what I have  
now.  If anyone else want to discuss this, it'd be a great point for  
this list - since I'm quite lost on my own :)

Cheers to all, it's great to meet some new folks here!
