[fprint] Door locks

[Lars Brandt]

Hi,

I am trying to start a small hobby project. Connecting a door lock to my computer running fprint in order to unlock door, play welcome message, etc. 

I have the working fprint and are now looking for the best solution to connect the computer to the lock. I am thinking to use some kind of relay to the serial port. 

Are there anyone out there that has done this or has other suggestion for the best solution hardware, serial to relay that is.

Regards, Lars
