Hi Rick,

Please excuse my delay in responding to your post. I read it last evening but have been a bit under the weather.

Where have you been hiding Rick?

I have a significant interest in much of what you are doing, particularly sensing electronically the angle of my Jeep's Center of Gravity in relationship to either the horizontal or vertical plane if gravity. Sounds to me like you have this all figured out. I have a ton of question and keen interest in what you have developed. I don't know what your plans are for this (Commercial or just a hobby like mine) but if you have the desire to share your knowledge either here or via email email.id@worldnet.att.net you will find a willing student on this end.

From my perspective I have two of the three pieces of the puzzle. I can determine exactly where the C of G of my Jeep is located, and I have the ability to alter this location to some degree artificially. The piece I am needing is How to monitor the C of G location in relationship to the vertical plan of gravity dynamically.

If you have an interest and have not seen the write-up I did on "Determining the Center of Gravity and Rollover Angles of Your Jeep" and care to invest your time you can see where I am at and where I would like to go with it.

it is available for download as a MS Word document and Excel Spreadsheet at:

or online at

To artificially manage of effect the C of G and related rollover angles I have installed an AiROCK air spring suspension. Info on this is in a write-up at
http://www.jeepbbs.net/forums/showth...&threadid=3030

Now if I can "see" where my C of G is dynamically while I am wheeling via the method you have developed I think that would qualify for having my cake and eating it too!

How are you interfacing those accelerometers to measure tilt with the outside world? Basic Stamp programming and chip? Were are you collecting and storing the data? Are your data points processed dynamically or just collected and batch processes at later time?

Obviously I am very interested in what your doing. Please feel free to share more if that is what you would like to do. But please "dummy it up a little for me". I'm not quite as talented as you are in this arena.

Have a great day,

Frank

PS: Please know, 3/4 of all I do has very little practical application for 99% of the folks here, but I do them becuase I want to. I enjoy pushing things and learning new things as I go. While I can't say everyone on this board would have an interest in what you or I care to do, I can say you won't be discouraged from trying something new.

Go for it! And if I can help I'd be happy to.
