Parallax Propellar Auto Pilot with OSD advancing
My Parallax autopilot with OSD (on screen display) is moving right along. It also transmits all sensor data to the ground station via XBee. Right now I have adapted Chris and Jordi's ground station to display most data.
Here is also the spin code....
BTW: Yes I know its corny but the ohm symbol is where 'home' is !
Here is a few pics as of 5/10/09

Interesting, what sensors are you using. How did you program the different cogs? Is Spin difficult? What is
your programming background?
The Alt = 6494, yet it says 55" above the ground, how can that be? BTW, it is descend, to go down!

The 6494 is the GPS altitude here in the mountains of NM on the bench. The 55 inches is with the ping device pointed towards the top of the room.
Spin is not difficult to program in.
Yes. I am not a good speller !

I climbed the Sandia mountain, but had to take the tram down. Are you making an ultrasonic altimeter?
Hard to get to work at even 10' I would think. Do you have accel and gyro?
Spin is like C? It looks like greek to me. What do each of the cogs do in the Prop?

Is the Arduino downloader program based on National Instruments software???
Your system is loaded, I see:
-6 DOF IMU
-ultrasonic landing altm
-artificial horizon
-compass/GPS
-on screen video
Are you going to make boards and sell them? It appears you don't need a thermopyle.

thermophiles don't work very well at night in the dark ! Thats why I went this way.

This says it does. But I think they are a lot of trouble. Dean has said they don't work
in the rain.
Since the infrared environment is not affected by variation in visible light levels, an airplane equipped with CoPilot could be flown at night. Only substantial changes in weather cause gradual variations in infrared temperature throughout a day. Heavy fog, flying through clouds, or snow on the ground cause the infrared signature to vary.

Great stuff, Earl. You're making terrific progress!

Earl, have been following your project. Excellent progress, and very good video guide/introduction. I see you have pretty much all the sensors, interfaces, and telmetry done. What is the core autopilot software? What will replace the development board once ready? Are you designing/making your own PCB and daugther boards?
Please keep us posted... -

They work perfectly well at night--that the advantage of using IR, rather than visible light. But they don't work well in the rain and heavy cloud cover and/or fog reduces their effectiveness.
Thermopiles are 90% as a good as an IMU with 10% of the complexity. A very good trade-off, I think.
