My boys and I recently had the chance to launch a ping pong ball containing an Arduino Pro Mini with a temperature and humidity sensor to the edge of space.  The experiment was wildly successful, and you can read about it on our site.

Explanation of the experiment, including the Arduino and sensor used:

Here's a quick photo for those of you who want instant gratification.  It went up to about 85,000 feet and we collected some interesting data.

That looks pretty large...

Just had a read - sounds like a pretty neat project. At least you're less likely to lose it if you send a load up together with some professionals tracking its location :D

Yes, from the JP Aerospace blog, it looks like they've tried RADAR in the past to track it.  They also show a ~20 foot directional antenna, so they must be using something specific to track it. 

The hardest part of this entire experiment was fitting the Arduino in a ping pong ball.  Luckily, the Pro Mini is just small enough to work.  If I could do it over again, I'd find a way to store more data than just what I can fit in the EEPROM.

well with custom PCBs you could fit an awful lot in a ping pong ball :)

MicroSD would be easy enough for storage.

This could be another interesting project - who can fit what in a ping pong ball :D

Wow!

I think that I will have to get a mini...

Thats one fantastic project to do with the kids. Nice :)

This is an old one, but when you are ready to have your own balloon ......

Awesome project. I never would have thought you could get an arduino in a ping pong ball. But I've never seen the mini in person either.

For the humidity when I first saw the graph and before I read your theory I was actually thinking that the increased humidity might be from condensation forming on the ball as it was falling. But that's just a guess. I'm not meteorologist.

The Mini is cool! And quite a bit smaller than the Nano V3 (which does have a 328 on it).  I have "open source copies" AKA Clones of these here:

I have one I'm putting together with two 9G servos and a cellphone battery for a SMALL robot...

The Nano plugged into a breadboard is nice to work with, direct USB.
