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:
