A board that has gyros built in- says that the board by itself can be used
as a 3 axis controller.
Vibration resistant enough for a model RC helo. If they can stand that much
vibration, they have to be tough.
What do you think?

We had a big discussion about this a while back. Gyros are built into some
cell
phones and tablets. There is some software for the tablets that use SS
gyros to give
the pilot synthetic vision.

I ordered a board, and after I play with it for a bit I will try to build a
3 axis autopilot. The board also has provisions to mount a GPS chip. My
boat has NMEA 2000 GPS signal output, and a simple hydraulic motor drive
steering. I can outfit the boat with the system by interfacing the motor
drives from the unit to the steering pump. I will try to slave the unit to
the output of the built in GPS, and compare the board GPS chip performance
to the built in GPS. The advertisements said that the software for an
autopilot was already available for download, which should give a good
starting point and save a lot of time.
I will try it on my boat first, if it can navigate the boat at 12 knots in
6 foot seas for 12 hours, it should work in the plane if it can update fast
enough.
Just a thought- after reading over the info, this system with an on board
GPS chip can be programmed with a destination, degree of rotation limits, G
limits, and using tables on an SD card, a flight profile. Meaning for
around $300.00 for board, chips, and 3 servos, I can program my plane to
take off, fly somewhere and "land" within a few feet of its target. It is
unlikely that I would get to use the plane again.
I will let you guys fill in the blanks regarding the implications.

I did some work on reading a GPS back in 1990. Here is my Kitplanes article.
I'll send some of the info on the NEMA 0183 interface as soon as I find it.
