My first PCB!  Printed the mask onto photo paper using a laser printer.  Transferred the mask onto the pcb using my iron, then etched the pcb in ferric chloride.  I'm very happy with the result for my first attempt.  Yeah, the soldering is a mess.  I finished it up at about 3am :)
Mounted to the wall!  Buzzer above the PCB gives you a 30 second warning before the garage door closes itself.  Currently set to wait 7 minutes before closing the door.  Toggle switch to disable the timer or abort closing during the alarm period.  The phone wires poking out of the wall are not my doing!
The original pcb layout.  Created with CADSoft Eagle.
Schematic.  Very simple layout.  Just an Atmel ATTiny microcontroller and a transistor to close the garage door circuit to close the door.
