[Linux-aus] Open source hardware for open source conference recording - now launched!

Wed Sep 23 00:58:01 AEST 2015

Hey Tim,

This is a really amazing effort. Congratulations to yourself, your team
and everybody else who worked on this project. I look forward to seeing
it in use at some of Linux Australia's events!

Thank you for continuing to enable our freedoms and for all you do
within our community.

Cheers,
Josh
