Hello everyone! I created this blog as a sibling of my (precursor) Open USB FXS blog http://openusbfxs.wordpress.com/. The purpose of this blog is to document the process of getting through the design and build of a complementary device to Open USB FXS, this time called Open USB FXO. And, what else would this device be, if not a USB FXO interface?
As with its sibling FXS project, the newborn FXO design starts at a very early stage — nothing even close to a working prototype. In the next posts to come, Open USB FXO will materialize into a real circuit and start getting its share in pestering the world with the same childhood diseases — bad analog design, bad audio, etc. etc. — as its older FXS bro. Hopefully, all to be fixed in the end.
