Pumpkins outfitted with LEDs are certainly all well and good, but the ever-versatile Arduino platform has now upped the Jack O' Lantern modding possibilities considerably, and MAKE's Marc de Vinck looks to have made a decent stab at things with this immodestly dubbed "scariest pumpkin ever." To help it snag that title, de Vinck did away with the usual spooky halloween sound effects and instead opted for a car horn, which lets out a blast whenever someone presses the impossible to resist red button. That, obviously, presents a number of problems, and MAKE warns not to leave the pumpkin unattended, or let someone press their ear up against it. Or, if you're not quite ready to tackle the project yourself, you can simply get a taste of it at a slightly more tolerable level by checking out the video after the break.
