AVR data transmission WhereAVR

[mcmahan]

This seemed useful for the near space team, but seems to useful to put in that thread, so I gave it its own. The WhereAVR seems like a pretty cool little gadget. Its an AVR based data trasmitter, that uses basic HAM packet protocols.

yeah another aprs device

but does it have Open Source code and hardware?

[WinfieldMike]

Its about as open as you can get...he has the source code and even the board files available. It prob. wouldn't be too hard to make on a standard prototype board or breadboard just to see how it works.

ok didn't see code or part layouts on link listed

google came up with this though

with simple description with enough detail to cover everything

[WinfieldMike]

When you click on Tim's link below, you see just a summary of the article. Below the fifth paragraph on the right side there is a {READ} link that takes you to the whole article. Way at the bottom is the download link for the source and the board files.
