I have the factory schematic for the old big box version of this and it could be interesting, nothing much to say about it other than it seems like a nice FET compressor and shouldn't be too much of a struggle to fit a 1590BB and not use a 40V supply for something regulated to 12V inside.
Has a lamp setting so i'm sure this http://www.smallbearelec.com/servlet/Detail?no=716 would fit the bill.
Bean's yet to have a full featured compressor so this could fit the bill.
It's a compressor that I haven't built, so I'd be in ...
The production units are noisy, though. Sooooooooo noisy. :'(
