Need help/ideas for a (seemingly) simple USB, time controlled locking mechanism Answered

Hello. I need help. A lot. But seriously, I need to fabricate a way to activate a door lock, via USB (this would seemingly be the easiest way, since a computer keeps accurate time), only during a preprogrammed time period. For example, I would program the lock to activate at 11:00 pm and retract (I'm assuming deadbolt here) at 5:00 am. Would something like this be possible?

Thanks in advance.

Try investigating the use of a micro controller. Something like the Arduino platform. You can get a good timing circuit for the Arduino. When the Arduino detects the appropriate time it can set of a relay which activates a servo which can side the bolt in and out of place. You can find plenty of instructables that use an Arduino is various ways to control a door lock. Couple that with an instructable about using the Arduino as an alarm clock and your on your way.
