"I have to say I am very excited about this project. I am looking forward to getting the hardware and trying it out. I also hope to be able to contribute at some point in the future."
"Yes it runs FreeRTOS and they have a abstraction layer on top of that called PiOS."
"William,
That is the problem, here is a graph with the board upside down. The Z voltage only drops to about 1.67v which doesn't seem right."

I have the MMA7260Q breakout board from SparkFun and here are the values from the X, Y and Z accelerometers with a 3.3v power supply.X Y Z1g 2.54v 2.35v 2.61v0g 1.71v 1.54v 2.21v-1g 0.9v 0.73v 1.67vThe Z readings seem a bit off, according to the…
I am looking at the Failsafe Mux in the store and I have a few questions. I assume the mux can be used stand alone without connection to a microcontroller? What is the purpose of the microcontroller pins? I think I may be missing something here.…
"Integrate a GPS and send the coordinates back to the ground is one idea."
"First off if I may offer a bit of advice, try using correct spelling, capitalization, grammar, etc. People will be more apt to take you seriously and try to help you out. Then if I were you I would start by scouring the site and soaking up the…"
"Is it a 5v part? If so I imagine it's putting out a voltage between 0 and 5 volts depending on the acceleration(tilt). So you need to read this voltage with an AD converter and then decide what you want to do."
So I am looking to use a MPX4100A to measure altitude. This part is a 5V part and I am using an ARM processor which runs at 3.3V and the max Vref for the AD converter is also 3.3V. What is the best way to interface these two parts? Use a voltage…
"So are the Ublox GPS modules worth it? I hear good things about them but they seem to be hard to get a hold of at least here in the US. I am just looking for a decent GPS module to integrate into my autopilot. I have tried the Lassen IQ but I had…"
"Thanks, that was helpful!"
"Because if I bought an IMU off the shelf I wouldn't really understand how it works and I don't like not knowing how things work."
"Observing someone writing code is probably not going to help much, actually I would be quite surprised if you learned anything. I would think the best way to learn would be to figure out how the hardware works and fumble around with the code. It's…"
"Wow and I thought I was ambitious trying to create my own IMU."
"Any comments on using a Gumstix as the main processor versus a propeller or something similar? I would think the gumstix would give me more flexibility but may take more work."
