So in my typical fashion I discard any long term planning for a Halloween costume at the very last minute and take on insanely ambitious delusional projects in their place. It always involves a fair bit of scavenging and resourceful repurposing of things I’ve got laying around, this year it just so happened I had a bunch of WS2812 (Neopixels) LEDs and some styrofoam cups around the studio. I had seen people making cup lamps for a few years and then someone on my Instagram feed posted a picture of someone wearing one as a helmet. DING! DING! DING! insperation! Like almost everything I figured I could take it up a notch to near perfection with Der BlinkinLights.
I made my daughter this robot costume for halloween. I was inspired by this Kid Robot costume. I took mine in a bit of a different direction and added a few more novelties such as lights in antennae and ears, a big button pad with a sound effect for each sound, and my daughter’s actual voice for the candy detector and a few other phrases. I also added pressure sensors to her boots so that she had robotic sounding steps.
Adding quality audio to an electronic project is surprisingly difficult. Here is a shield for Arduinos that solves this problem. It can play up to 22KHz, 12bit uncompressed audio files of any length. It’s low cost, available as an easy-to-make kit. It has an onboard DAC, filter and op-amp for high quality output. Audio files are read off of an SD/MMC card, which are available at nearly any store. Volume can be controlled with the onboard thumbwheel potentiometer.

Adafruit GEMMA – Miniature wearable electronic platform – Love FLORA but want a bite-sized version? Look no further, GEMMA is a tiny wearable platform board with a lot of might in a 1″ diameter package. Powered by a Attiny85 and programmable with an Arduino IDE over USB, you’ll be able to realize any wearable project!
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 Flora and you aren’t willing to take apart the project you worked so hard to design. It’s our lowest-cost sewable controller!
The Attiny85 is a fun processor because despite being so small, it has 8K of flash, and 5 I/O pins, including analog inputs and PWM ‘analog’ outputs. We designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino (it uses 2 of the 5 I/O pins, leaving you with 3). In fact we even made some simple modifications to the Arduino IDE so that it works like a mini-Flora. Perfect for small & simple projects the GEMMA will be your go-to wearable electronics platform.
Even though you can program GEMMA using the Arduino IDE, it’s not a fully 100% Arduino-compatible. There are some things you trade off for such a small and low cost microcontroller!
Join Becky Stern and friends every week as we delve into the wonderful world of wearables, live on YouTube. We’ll answer your questions, announce a discount code for the Adafruit store, and explore wearable components, techniques, special materials, and projects you can build at home! Ask your wearables questions in the comments, and if your question is featured, you’ll be entered to win the show giveaway, which this week is an 4400mAh USB battery pack!
[Synth Hacker] was inspired by Adafruit’s Electronic Halloween, and in particular Becky Stern’s “Space Face” and “Firewalker LED Sneakers“, I decided that I had to make something light up this Halloween (and maybe wear some make-up, too). Here’s what I came up with.
Fantastic Job! Thank you Chip for sharing, we love seeing what you’re inspired to make.
Yet another epic project from the Ruiz brothers! This mask is horrifying yet I really want to make one for myself. In addition to the Halloween mask it looks like they used a pixel ring for each eye, three single NeoPixels for the mouth and one rechargeable lipoly battery.
HAPPY HALLOWEEN! Each weekday 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 on Google+, in the comments below, the Adafruit forums, Facebook, or Twitter– we’d love to see what you’re up to and share it with the world (tag your posts #ElectronicHalloween). Tune in to our live shows, Wearable Electronics with Becky Stern and Ask an Engineer, where Adafruit store discount codes are announced– get the most bang for your Halloween buck!
Me and my son decided to go treasure hunting with a metal detector that we have but we couldn’t find it anywhere. Being proper makers we decided that it would be more fun to build one ourselves rather than keep trying to find it.
Michael Nilsson and Marcus Olsson of slickstreamer have built a music visualizer into a table with LED lights that flash to the beat of the music.
This hack start as a idea to connecting Spotify to philips hue and make them flash in sync to the music. But during the path off the project it become more about led lights =)
There is four parts in the current configuration:
Raspberry pi controlling an addressable led stripe (optional)
Arduino controlling non addressable led stripe (optional)
Philips hue (optional)
Spotify have an api to get realtime analyse of the playing track so it is possible to do beat detection and other fun stuff. When i started this project I had no idea how to visualities music and just test different things to it locked good. The code is at the moment a mess but you can find it here
The raspberry pi is running a node.js app that is connected to a digital RGB LED Strip LPD8806 from Adafruit and the Spotify app is connecting to the node app using socet.io. Code
The Arduino is controlling Ikea dioder and are connected to the Raspberry pi using serial port and changes colour in sync to the beat and intensity to the base band. Code
The philips hue is more as some extra mode lights due to the hub is not not fast enough. Have only bean able to get one light bulb blink in sync whit the music whiteout lagging.
The Smart Coaster is an intelligent coaster for your beverages. It recognizes the different types of beverages placed on top of it, with a cocktail the Smart Coaster glows in some atmospheric and slowly changing colors. If you place a cup of hot tea on it, it automatically starts a special tea timer program which shows you, when the tea is ready to drink. If the glass is empty or filled with a cold drink the Smart Coaster glows blue, if the drink within the glass is hot, it glows red.
Unlike all the other temperature sensors we have, this breakout has a really cool IR sensor from TI that can measure the temperature of an object without touching it! Simply point the sensor towards what you want to measure and it will detect the temperature by absorbing IR waves emitted. The embedded thermopile sensor generates a very very small voltage depending on how much IR there is, and using some math, that micro voltage can be used to calculate the temperature. It also takes the measurement over an area so it can be handy for determining the average temperature of something.
