Picture of The mini pumpkin LED face

This is a very simple and fun project for kids as well as adults. Using a small pumpkin as a circuit board I created an LED face powered by a 9v battery. This can be a neat little Halloween decoration for work or home. Now, on to the instructable.

Step 1: Materials

Picture of Materials

The main materials for this project is a little pumpkin (bought for about 70cents), a couple resistors and 7 LEDs.

5 LEDs were used for the pumpkin face and 2 for the eyes. Two current limiting resistors will double as eyebrows for the face.

I just brought a mini pumpkin and I was wondering what to do with it
and here it is a led pumpkin.

that is cool
That's very cool! I'm surprised that the pumpkin doesn't short out the components. Someone should sell a kit that has a flexible PCB inside the (fake) pumpkin so you can just snap in the LEDs in the position you want for different faces.

nice looking pumpkin there, great idea! Looks like you got all of your tools at the shack. Is your soldering iron the 60 dollar one?

the soldering iron i had for awhile and i think it originally came from the shack. leds are expensive if you pick them up at radioshack so i suggest buying online somewhere like ebay.
