"Hey Bryan,
I was trying to take a look at your Windspeed Algorithm spread sheet to see how you are doing it. It seems to only be numbers. Would you be willing to share some more info on that with me?"

I've been looking at xbee to the phone as well. Unfortunately, getting a wired serial connection to the phone can be pretty tricky (and quite possibly impossible on non-HTC phones). Having to go…"
Bryan commented on Bryan's blog post Android to Arduino"No idea yet. The hope is to be able to wireless-ly update waypoints and stream telemetry (video would be awesome too) thru an arduino+xbee to the phone. I'm going for portability."

Found this website just now, and it matches up with my eventual goals. Enjoy and happy hacking.http://www.amarino-toolkit.net/index.phpSee More
Bryan replied to Joel Ryan's discussion UAV object tracking"GPS and an XBee was my first thought for the beacon."

Help? Trying to analyze a design and it tells me that it cannot find the foil.

"Byran, questions are better posted in the discussion forum, not as a blog (which are mostly meant for information of use to the larger DIY Drones audience)."
Bryan commented on Bryan's blog post Airspeed"Clarence and Chris, there are two ports on the Shield to measure the difference between the pressures. Even if the reading is not a direct comparison, its still comparing the two pressures to a reference, which does the same thing. This looks like a…"
ModeratorChris Anderson commented on Bryan's blog post Airspeed
"Clarence, technically you're right, but in practice there doesn't seem to be much difference. The cockpits aren't airtight, so the heat doesn't seem to lead to much if any pressure increase."
Clarence Hanson commented on Bryan's blog post Airspeed"So I could be wrong, but I do not think you should think of the differential pressure sensor as a pitiot tube. A pitot tube takes the static and pressure from the same air flow, but with the shield one pressure is read from the flow while the other…"
Bryan commented on Bryan's blog post Airspeed"And you're correct. Got the compass module up and running in a previous post I believe has since been deleted. Here's the algorithm I made up to get windspeed and direction. Highlighted in yellow is the input from the sensors needed, with…"
Fred Forbes commented on Bryan's blog post Airspeed"Once you have established a good airspeed while flying and GPS is giving you course over ground (with respect to true north) and speed over ground, I don't see how you can compute wind speed and direction. I would argue that you also need true…"
Jason Larocque commented on Bryan's blog post Airspeed"I agree with you. I wanted to mention it for those who didn't know about the possible errors !"

Now onto trying to get the differential pressure sensor to do... something. I have the Ardupilot Shield alone with both 3.3v and 5v attached. Analog 3 on the Shield is connected to analog 0 on an Atmega328. Took some trial and error to get the code to read something meaningful (I'm new to this, obviously), and after that was on to road testing. I got the pitot tube from an R/C website, but don't remember which. Here's some redneck engineering at its finest:…

If anyone's interested, here's the code I used, slightly modified and spliced from the internet. This is for the SCP1000-D01, with my temperature running about 35 degrees F hot which for now I'm attributing to the heating from the amperage:
// define spi bus pins
#define SLAVESELECT 10 //CSB
#define SPICLOCK 13 //SCK
#define DATAOUT 11 //MOSI
#define DATAIN 12 //MISO
#define UBLB(a,b) ( ( (a) 8) | (b) )
#define UBLB19(a,b) ( ( (a) 16 )… Continue
