From a distance. When you get close you begin to notice the calluses and warts. It is sill a good airplane.
You mean the yaw string? ;) [ The ILEC in the panel looks nice too. ]
Thought about it, and may try it in early versions to save some wiring and development effort on the display side, but I doubt I'll use it in the final system.
I believe (prejudice, not research,) that the fully wired CAN version will be much more reliable. (1) [ "Tower, experimental on final is going around - need to pair my instrument panel with my pitot again."
- Note I am trying not to say re-pair ]
In a sailplane you can expect all the electronics to be clustered in the cockpit, and to have few or no sources of interference. (Radio mostly in receive mode, FLARM? )
I have to locate the sensors in the outboard sections of the wing, to keep them away from the prop's stream and engine influence. Again, there are double CDI ignition systems, transponder.
How does bluetooth work in this environment? What is the effect of other people walking around the plane with bluetooth enabled devices while in the ground? Probably it can be made to work reliably, but I read enough stories of people having trouble using their bluetooth phones with their bluetooth car stereos. I'd rather avoid the extra R&D effort and stay with CAN.
Will set up a web page when I have something to show.
So far I ordered the following:
1 x ArduIMU 1 x Android Open Accessory Dev Kit 3 x LPCXpresso boardsplus a Dell Streak 7 tablet I already have. No GPS on the first stage. The Xpresso board can be split into the processor proper half and a debugging / JTAG programming half. It is inexpensive enough and small enough that I doubt I'll design my own boards.
The only major ingredient missing is free time. I am working on getting the plane itself back in the air, steam gauges and all.
