This is my honking pumpkin project to scare Trick-Or-Treaters. The little monsters will not be able to resisted pressing the red button on the pumpkins nose which will trigger the eyes to glow for a second and just when they think that’s it a set of 105 decibel car horns hidden in the pumpkin will blast and send them running.

For the most part my plan worked on Halloween 2008 but I built it fast and with some cheap parts. What follows is documentation of my re-build to remove some heinous false triggering and general improvements. Enjoy the below videos and photos.

Parts list is at the very bottom and here is a link to the circuit:  –>circuit
