Got more stuff in the mail today. The power supply and an order from Mouser (all the electronic bits except for the perfboard) arrived.
I'm waiting on some hinges and latches, and the perfboard, but they should be here Monday or sooner. The one piece of lumber I don't have will arrive tomorrow as well, for sure -- it's being brought by a friend, since I'm "transportationally challenged" ;)
When everything's here I'll take some pics before I start building.
