This is far less of an "oh no" than it is an "Oh, rats". First, I had a production problem: I made 8 white MacSAOs, and cranked the toaster oven too high: I burned them. While I was hoping that it might give a kind of nice Beige color like the original Mac, they really just look like they were in the oven too long (which they were). Fortunately I had enough extra PCBs to make my goal (50) so I did another batch of the white. 

The biggest limiting factor on how many I can make is the number of i2c displays. I only ordered 55 total, so I had a few to lose. After all is said and done, I expect to have 51 SAOs total.

The second 'oh rats' came when I took a picture of the final product to post here, and I noticed that the detail line that breaks up the top of the Mac and the 'foot' somehow did not make it into the final product. 

It's purely aesthetic, and I didn't notice it until after working on it for 2 weeks. So I'm just kind of bummed about it.

I've got 40 white MacSAOs made, and 2 Black (I'm making 9 more). 

Supercon is just a couple of days away at this point, so we're in the final stretch!
