Building the PC housing

It's been a power weekend.  I cut out the walls and assembled them together.  It would have helped if the base had been a perfect rectangle.  Oh well, just plane off a few more mills!

The walls are made of 3mm MDF, screwed onto a quarter section of 20mm round dowling.  It will be quite sturdy, after it has been screwed onto the base, and fitted with an acrylic front plate.

SWASC Project documentation

During the week, I played around with ExpressSCH, a electronics design package.  As a test, I laid out my initial PICAXE test circuitry.  It comes up better in the original size.
