We had the revisions made for the V0.5 board the night we received the V0.4 batch. Put it together, ran it through the ringer and made a list of fixes. I just made the first V0.5 fully-functional board last night and we have a list of stuff to change for the V0.6 as well. Gotta keep making things better.
As for the workers, well they're gonna get a full retraining this week on surface-mount soldering and general quality standards. One of the guys is already putting out pretty good work. He's my least-experienced minion, with the least free time, and is putting up more productivity and the highest quality of work.
