Speed Sensor Anyone???

Thanks Steve!
I have been flying airplanes since 1973 and helicopters since 1994 (the real ones not the models) so I agree with you completely. Typically in most lakes or even a swimming pool the water is pretty much stationary. I will probably take an extra depth sensor and spin it in a plastic trash can filled with water at different speeds and see what "head-on" pressure readings I get. Hopefully there will be major changes in the readings? My fear is that the pressure at slow speeds will be to small to see. There are just so many details to work out on this sub project. For example, no one seems to know if First Person View goggles display video in underscan or overscan. This makes a different with trying to use an On-Screen Display character generator as with overscan as with a CRT TV you do not have the first column available and thus you are limited as to how many columns are useable! So many questions, so little time! Lol Best, Ed

From your posts, it sounds like an impressive project and quite an undertaking.

My fear is that the pressure at slow speeds will be to small to see.

I can understand the concern. I would expect it would take some rather sensitive pressure sensors to pick up the differences in pressure at slow speeds.

Keep us updated on how things progress!
