Candy is an important part of Halloween! However, eating all that candy can lead to cavities. Make brushing fun this Halloween by creating your own electric toothbrush! All you need is a toothbrush, rubber bands, a wooden block, and littleBits! This toothbrush also has a programmable timer so you can decide how long to brush your teeth for (the American Dental Association recommends brushing your teeth two times a day for two minutes). Show that sweet tooth who’s boss this Halloween.
This Lego cockroach behaves similarly to real cockroach, making it a great Halloween prop. It is able to navigate tricky spaces and it scurries when it is exposed to light. When it finds a dark place to hide, it lays low and stays put. See how this clever circuit combines bend sensors, inverters, and light triggers to create this lifelike interaction.
In honor of the littleBits Halloween Costume Contest, we whipped up our own Halloween costume. This glowing dinosaur can be made with the light wire and an old hoodie. Learn to use the light wire as a structural element and light up your night this Halloween. See project details here.
Here’s a project to dazzle onlookers at Halloween parties, cosplay conventions, raves or at Burning Man. These full-color animated LED goggles attract a LOT of attention!
Adafruit NeoPixel LED rings fit perfectly inside the eyecups of most 50mm round goggles — a very common size. It’s almost as if these rings were made with this project in mind! (Actually, they were…then our clever customers came up with a million and one other uses.)
NeoPixel Ring – 16 x WS2812 5050 RGB LED with Integrated Drivers — Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75″ (44.5mm) outer diameter. The rings are ‘chainable’ – connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED.
Adafruit TRINKET – Mini Microcontroller. 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!
Have you ever done something silly on a lark and then found it was a big hit? So it went with a “beta test” Halloween idea on the Adafruit Show & Tell last week of my electronic demon costume. This video is a summary of what was done there… and what I’m now scrambling to finish properly before the big day! Video on YouTube (please subscribe!) and Vimeo.
Some updates since this was shot: a Ustream chat participant during Show & Tell suggested using a paintball mask as a base. I’m currently working on the faux ribcage idea… there may be enough space to move most of the electronics there and have just batteries in the pack. We shall see!
HAPPY HALLOWEEN! Each day this month (Monday-Friday) we’re going to have a special “Electronic Halloween” post here on Adafruit. It will be a hack, mod, project or something we’ve found that combines all the best things about electronics and Halloween.
