Alarm Clock of Justice

The Alarm Clock of Justice wakes your computer from standby and hibernation to play an alarm consisting of movies, music, CDs, and/or running programs, scripts, batchfiles, and ANY type of file your computer knows how to run. Alarms can also include web addresses and a built-in reminder system can speak reminders with a customizable display (including flashing random colors). Volume effects include unmuting the volume, setting the volume to a certain level, random volume, and alternating the volume between two customizable levels for four customizable amounts of time.
Built in support for Windows Media Player is included, and used as a backup in case your regular media player reports an error. Waking from standby and hibernation is customizable with the amount of time to wake up from before your alarm plays, whether to enable "insomniac mode", and whether to play your alarm if your computer wakes up within a customizable amount of time (default: 60 seconds) of the alarm. It runs in the system tray and can optionally run at startup with a specific configuration. The time format is customizable (24 hour or 12 hour). Extensive tests are included to make sure your computer can wake from hibernation and standby. Configurations allow for unlimited alarms.OS: Windows 2000, Windows XP, Windows Vista, or (probably) higher. http://www.forrestheller.com/alarm2/

Turn on lightbulb with the Alarm Clock and a printer

used the Alarm Clock of Justice 2.0 to run an AutoHotKey script that made a printer print a file. The printer cartridges are connected to a string which is connected to a light switch. This video has very bad quality and editing.
