There has been a recent surge in views on youtube! We just broke 36,000 hits!
We sent up a Twinkie and a marshmallow on the top of the payload capsule to see what would happen to them at 90,000 feet altitude.
Well, as you may have guessed, other than a semi-frozen filling, nothing happened to the Twinkie at all! The marshmallow did expand a bit but also tasted “normal” 🙂

I spent some one on one time getting to know MS Excel’s VLOOKUP function in order to merge the Arduino temperature data points with the APRS altitude and speed data and then created an interactive graph with the results using Google Docs – pretty interesting stuff:
Here is a screen shot of the flight data… I’ll post a Google Earth KML file later when I figure out how to generate it from the raw telemetry data.
Note the few minutes spent falling over the Pacific Ocean!
The Arduino worked perfectly and took 5755 temperature readings inside and outside the capsule.
The capsule was not air tight but still acted as a pretty good buffer for the internal air temperature.
We just got the balloon back. It landed on a soft patch of grass. We will post raw video and pics ASAP with an edited video coming soon. Stay tuned as more content is released. We also saw it land and a partner might have videoed the land
