As I look in more and more for this page, I am not quite sure about this GB. When I read this post, GB page isn't that different from IC. I think it is wise to do GB after Chinese spring holidays with enough samples and consider about these demands. But at this point with these uncertain status I don't feel like joining.
I'm certain this project has been well prepared at the current stage, that's why GB comes out.
I've got a lot of experience from the the previous project snowflake. The GB was canceled but everything was finished and tested.
Right now the prototype is almost perfect which well verified the design. The PCB is a previously designed PCB with mature firmware. The change on the case for supporting mid diffusers is a very easy modification. Nothing can go wrong. We're not bottomnecking anything.
This is the first GB of mine but won't be the last one. I won't take any risks to make my first batch of supporters down, and they will not.
