Sometimes at bed time when it would be to late to start anything else I tinker with some electrical projects.
I have read a bunch about the standard Flap motor not being "perfect"
During the rebuild of the other RV7A with G3X system the flap position was missing. So I added with a ray allen position sensor. It also had the "Flap Positioning System" by show planes.
Sensor mounted to the motor
Potentiometer mounted to the motor
This kicked of this idea. There is got the be a simpler way.
What I came up with is a motor that has it's own potentiometer inside.
Then I got a arduino board to play with and after about 3 months I got the first beta version that does everything I want it to do.
My system mounted to a board
I had originally copied the switch that all the other systems use but then changed my mind to a rotary knob.
I made another version but I havent decided on the final one. (these are rough prints from the 3d printer. I would like to get the final one made out of Aluminum CNC.
I also have some LEDs. they are on the board now for testing but I want them to be mounted next to each position of the flap switch
Then I added a GPS and that lead to a few new possibilities.
I was able to set up an over speed protection on the flaps.
I also included a wig wag module. This is also driven by the GPS.
Now the last piece of the puzzle was to make an output that the garmin g3x systems can read. (I suspect others would work too) I borrowed the gea24 and a g3x display from a friend to do this test.
Works like a charm
So far I have only tested the system in the car while driving and it performs great there.
