Hi folks, I happen to be developing just such a device called Jaxcore Spin:
I don’t have much about it online yet, but you can see some more pictures and videos of it on twitter https://twitter.com/jaxcore
My device isn’t meant to be mounted on a wall though, it has wifi and is meant to be portable and “coffee table usage” focused. It controls stereo receivers over your wifi network and could potentially support any receiver that has wifi support and published their tcp/serial codes.
I’ll definitely have support for the new-ish models of Denon/Marantz and Anthem receivers because I happen to own those kinds. And I’ve already open sourced the Javascript API so other receivers could be added later. Or if you know how to do an IR blaster setup and know Javascript you could write your own adapter.
I am currently looking for early adopters / beta testers.
Dan
