I hope to have an announcement on that in a week or two. Building and pricing hardware is hard!
Just to clarify though, you don't need a Tidbyt device to use the Pixlet runtime. It outputs GIF's and WebP's that you can "run" or serve wherever/however you'd like.
Yep pixlet is very cool, but I want a Tidbyt :)
I'll sign up for the newsletter and wait for your announcement
