Todd Harrison came up with a great way to scare anyone who dares to press the red button nose of his pumpkin. The Honking Pumpkin is sure to be a hit sitting on the front step of your house.

"Control board showing the two 555 timers, two MOSFETs, pot to control horn blast timing and other discrete elements. The first 555 timer starts when the red button is pushed and it turns on the red 12v bulbs through the 1st MOSFET (P10NK60ZFP). After 1 second this timer stops and cascades a pulse to the 2nd 555 timer which repeats the process turning on the horns through the 2nd MOSFET and relay."
