Why? - Obviously to assert that your knowledge and experience is superior to others with a different opinion

I work with smartphones. You are not going to see 9 axis sensors in a phone soon for this application. Must have been a while back TomW... Samsung GSx have had 3axis mag + accel + gyro since version 3 - and they are certainly not the only ones... Most high end Android phones have these sensors alon...

Every year we go down to our local beach access way and plant 500 dune plants along the edges of the dune within approx 500 yards either side.

I have a Ublox gps module with integrated antenna attached to an Arduino Nano and 433MHz transmitter along with a lipo battery. The whole setup is approximately half the size of a cigarett...

some people think you have to have a curved upper surface of a wing for it to generate lift. This is obviously untrue. Stick your hand out the window while you are driving the car and tilt it up. Your hand will be pushed up. That is lift. It is caused by the angle of attack of your hand to the wind...

the foil must generate lift. a doubt 'flat' will generate enough lift to make you smile. i'm not an engineer but i have slept in a Holiday Inn Express. This is not true. Check out any angle of attack / lift coefficient diagram for instance here's one with a cesna and british jet edt, please pardon ...
