Adafruit is celebrating Electronic Halloween all month long.

Here is a great 3D printed project to under take just before Halloween. Follow the steps below, to make your self a Wearable Light Up 3D printed Jack-O-Lantern, which you can wear around you neck, or place on your work desk to get you in the Halloween spirit…

For the build you will need a 3D printer and preferably orange and transparent filament to print the pumpkin, and an Aduino based micro controller which can be used to light up a 4 neopixels/RGB leds. In my case I am using Adafruits mini trinket and a 110 mAh lipo battery to power the circuit.

HAPPY HALLOWEEN! Every day this month we’ll be bringing you ideas and projects for an Electronic Halloween! Expect wearables, hacks & mods, costumes and more here on the Adafruit blog! Working on a project for Halloween this year? Share it with us in the comments below, the Adafruit forums, Facebook, Discord, Instagram or Twitter— we’d love to see what you’re up to and share it with the world (tag your posts #ElectronicHalloween). You can also send us a blog tip! Tune in to our live shows, 3D hangouts with Noe and Pedro, Show and Tell and Ask an Engineer, featuring ideas for projects, costumes, decorations, and more!

Featured Adafruit Product!

Adafruit Trinket – Mini Microcontroller – 5V Logic; Trinket may be small, but do not be fooled by its size! It’s a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don’t want to give up your expensive dev-board and you aren’t willing to take apart the project you worked so hard to design. It’s our lowest-cost arduino-IDE programmable board!
