Hack your pumpkin into a sound-triggered jack-o-lantern! It’s the perfect way to keep trick-or-treaters on their toes. Need your pumpkin’s light to turn on and stay on? Simple, just remove the sound trigger and you’re good to go!

To make a pumpkin that lights up when it hears noise
Make your circuit of Battery-->Power-->Sound Trigger-->Bright LED
Place your circuit inside your carved pumpkin. By adding the Sound Trigger, the Bright LED will turn on when it hears noise. Use the included Shoes to help adhere your circuit to the pumpkin as needed.

    Step 1

    First, you will need a medium-sized plump pumpkin. We recommend not using those GINORMOUS, man-eating ones, otherwise the LED won't shine through.

    Step 2

    Next, you need to trace your design onto your pumpkin. We used a Dracula-ed version of our icon aka BitGuy. Download the PDF below, or use one of your own designs! Carve your pumpkin and remove all the guts. PRO TIP: spray the inside of your pumpkin with bleach to fend off mold.

    Step 3

    Now it's time to create your circuit. Attach your battery to power + sound trigger + bright LED. You'll need to calibrate the sound trigger so that it triggers the LED at the volume you think is right. Use the teeny, purple screwdriver to adjust the sensitivity.
