Thought I'd add a little update to this thread. The project is progressing fairly well. We are still using the accelerometer as an incinometer, and are using a $50 compass module for the rotation information. Most of it is basically working with the exception of the wind sensor. We have 4 more weeks to get it working completely. I'm using PICos18 (http://www.picos18.com) which is turning out very nicely btw, check it out. ~Jake B -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
