Hi ADI,

I THOUGHT you would like those. They are not the only guys producing this type unit. So maybe we can find a workable small quantity source.

I haven't been real aggressive as yet as I was unsure if you electronics guys thought we could integrate these and they were the TICKET. Hopefully you guys can intuitively conceptualize a simple integration. Am I correct, that these can simplify the board and programming??

Also, I am unsure of many of the optional parameters to chose, especially output. There are pulse and analog options out there. Looks like the vibration tolerance is good as well as the shock resistance.

I have since learned that "in the sensor biz", Piezio is considered to be very substandard technology for these purposes...may be part of the trouble.

I also found these.. [X(]by trying to find digital inclinometer sensors as used in digital levels. I plan to go find a digital level in a store and play with it a bit. Have to be careful though there are different setups...some more intertia sensitive than others. While pitch and roll gyros are good, they don't know where "back home" is, and normally need corrections for the various ways they wander.

These tilt sensors are available in variable viscosity so you could get a dampening effect to eliminate the sloshy jitters. I sat here playing with a glass of water, and boy it sure looks like something like a light oil would work great. Even with water, accelerations really have virtually no effect on the average surface plane. I almost think these may be able to eliminate gyros altogether...for the DF. For the moment, I can't see how, with these tilt sensors properly integrated, that a DF wouldn't practically auto hover. Maybe I have't thought it thru enough.

Here is something else to look at. Tilt sensor...with a mini slot car track built right into the board..phenolic must have been on sale??

Boy, what jacks my crank is how stingy so many of these websites are with data. Jeez, with the web, if I was trying to sell something I would leave no word left out. Far as I know, server space hasn't killed any trees. And so many leave you clueless about how to get what they have.[:@]

Anyway..Cheers,
John
