Brief October batch update: The last of my parts orders showed up today and I've been jumping in. I started working on HW board assembly last night and got all the Slampeggs and DWs soldered up, and I've been working through the enclosure milling process. I'm going to try to get all enclosures milled tonight, but it may have to wait until Sunday (I'm taking Saturday off as it's my wife's birthday).
It's too early to tell one way or the other, but I have every reason to expect that I will be finishing the October batch on time before the end of the month, which is ideal as I would prefer not to have to work on Halloween.
Super quick BLK 3.0 notes: the paint showed up today and I played with it very briefly. It doesn't stick at all to a bare aluminum enclosure, it just wipes right off. Back in my acrylic spraypaint days I used self-etching primer with good results, so I have a coat drying on a test enclosure in the garage, then I'll try again.
I did spread a little BLK 3.0 on a cardboard box just to see what it looked like, and at first it just looked like black paint, but after it dried it's noticeably blacker than black and matter than matte. Very interested to see what it looks like when applied more evenly over a large multi-dimensional surface.
