Of course, the real bitch about doing a fab in your garage, as opposed
to most classic computing, is the really high temp furnaces, and the
rather toxic chemicals you have to use. I'd imagine that you could get
in a lot of trouble with, eg, the EPA (or maybe even the DHS nowadays)
if someone found out you were doing a fab at your house, in the US.
