I was thinking earlier on about locking plastic pants, then remembering something I read online (not this site) about wishing they could use their computer to control locking plastic pants key release time etc... So here is my idea: Take an old CD-ROM drive, open it up (I mean unscrew it, just to be sure) and fix the CD tray to be a full tray, with no holes. Remove the drive motor (not eject, just spin up). Close the thing back up, throw it in your machine and write a program that can lock the drive tray closed for a set amount of time (this is what some programs use to avoid execution errors with their programs when running of disc although it can sometimes backfire). After the set amount of time is done, the tray is unlocked and you can hit eject, grab the key and unlock the plastic pants . I'm going to try this little project probably next weekend (or tomorrow if I have time, though probably not) and I have to buy a pair of locking plastic pants!!! What do you think of this idea?
