Here’s an interesting website that tracks some probably not all hobbyist balloons around the world.

Here’s a link to a Ham Radio Operator that has detailed step by step instructions including pictures of how to build a Pico Balloon capable of circling the globe that can be tracked.

The cost of building a fairly sophisticated Pico Balloon that’s trackable is probably less than $500 dollars and often times much less than that.

All I ever did, as a Ham radio guy, was talk around the world on my radio. It was great fun.
