The hack is to assert control over the buttons of an alarm clock using a microcontroller. The microcontroller serves to interpret commands recieved from an IR reciever/demodulator, and metabolize those commands into useful sequences of alarm clock keystrokes, allowing you to set the alarm time, snooze, dimmer, etc… as if you were at the clock actually pushing the buttons. Since you’re using a microcontroller though, you needn’t simply tunnel buttons on your remote to the buttons on the clock. You can maintain the clock’s alarm state inside the microcontroller, and use it to set the time in a more intuitive way, say, by pushing number keys, instead of clicking HOUR or MIN a thousand times.
