Arduino-based barometric altimeter / altitude deviation alerter
While working on my instrument training, it occurred to me that I had everything I needed in my parts bin to build a device to help alert me to deviations in altitude. So, I built MonkeyAltimeter. It started off on a breadboard while I worked on the code: Then, I took it for a flight test (primarily to see how accurate it was in the cabin and see if my VSI routine worked): Finally, I designed and printed a simple case for it: The details, parts list, operation manual, &etc are here: http://www.thingiverse.com/thing:942832 The source code is here: https://github.com/phreakmonkey/MonkeyAltimeter Enjoy!
