Embroidered Nyan Cat Brings a Meme to the Real World

Have you ever come across an Internet meme and just thought to yourself, “I have to bring this into the physical world!” Well [0xb3nn] and [Knit Knit] did. They decided to take the classic nyan cat meme and bring it to life.

The frame is 24″ x 36″. Many hours went into the knitting process, but the result obviously turned out very well. The stars include 24 LED sequins to add a sparkling animation effect. These were sewn onto the back of the work using conductive thread. They are bright enough to shine through to the front where needed. These connect back to an Arduino Pro Mini 5V board.

The Arduino is also connected to a capacitive touch sensor. This allows the user to simply place their hand over the nyan cat image to start the animation. No need for physical buttons or switches to take away from the visual design. An Adafruit AudioFX sound board was used to play back a saved nyan cat theme song over a couple of speakers. The source code for this project is available on github. Be sure to watch the demo video below.

Social Vibes’ is a Masters Degree (MSc.) project, in Interactive Media by Cian McLysaght, at the University of Limerick, Ireland. They shared with us their project, running on Arduino Uno, composed by a physical artifact designed and created specifically for an installation adopting the fundamental sound mechanisms used in a vibraphone, know also as a ‘Vibe’:

The instrument consists of twelve musical tones of different pitches. The music created on the instrument is derived from a continuous stream of input via multiple users on Twitter and the explicit interaction from Twitter users, tweeting the instrument directly to the project’s, “@vibe_experiment” Twitter account. Data associated with the emotional status of Twitter users, is mined from the Twitter network via Twitter’s open source, application programming interface (API).

For example if a user tweets “The sun is out, I’m happy”, the code I’ve written will strip out key words and strings associated with the user’s emotional state, within the tweets, ie “I’m happy”, and translate this to a musical notation. Mining Twitter’s API, allows a continuous stream of data. These emotional states are then mapped to specific notes on the physical musical instrument, located in a public space. The tempo of the musical expression will be entirely based upon the speed and volume of the incoming tweets on the Twitter API.

Twitter users who are both followers and non followers of the musical instrument’s Twitter account (@vibe_experiment) can tweet directly to the instrument and this direct interaction will be given precedence, allowing user’s who tweet directly to have their emotional state ‘played’. This allows users to hijack or take over the instrument and experiment with it in a playful manner, but also allows those with musical knowledge the potential to compose simple musical arrangements. When users are not tweeting the instrument directly, then the instrument will revert to mining the Twitter API.

To entice users to interact and observe the action of the instrument there is a live streaming broadcast of the instrument via Twitcam on the Vibe’s Twitter account. This is a live streaming broadcast of the instrument via Twitcam on the @vibe_experiment account. Twitcam, is Twitter’s built in live-streaming platform. This simply requires a webcam and a valid Twitter account.

The instrument constantly tweets back updates to it’s own Twitter account to not only inform people of the general status but also to engage users to interact directly with the ‘Vibe’.

Fifty speakers for an interactive sound sculpture

hive_2_cu

Hive (2.0) is the second iteration of an interactive sound sculpture consisting of fifty speakers and seven audio channels. The sensors detect the proximity of people and Arduino manipulates audio according to it.

hive_2_ls-e1418336047882

It was created by Hopkins Duffield, a Toronto-based collaborative duo exploring ways to combine both new and familiar mediums with artistically technological practices. In this work they used Arduino Uno together with Max 6 / Max For Live.

Sugarcube, a grid based music controller with accelerometer

Once again Amanda Ghassaei sent a cool project she’s been working on lately as an extension of the work she’s been doing on the monome project. Sugarcube is an open source, grid-based, standalone MIDI instrument  self-contained and relatively cheap to make. It communicates via a MIDI output with other electronic MIDI instruments and software environments like Ableton and MaxMSP.

An Arduino Uno generates all of its MIDI data and drives LEDS, buttons, a 2 axis gyroscope, a 3 axis accelerometer,  two potentiometers, and the whole device is powered by a lithium-polymer battery making it pretty portable.

She published detailed  documentation on Instructables to make one yourself   and shared a bunch of videos to discover its main features:

Basically this project is:

A portable, Arduino-powered, grid-based MIDI controller that boots up into a variety of apps to do lots of things with sound. The controller has 16 backlit buttons, used as both inputs and outputs to give the controller some visual feedback. 2 potentiometers give analog control, depending on the app the pots are assigned to tempo, MIDI velocity, pitch, and scrolling (making the avaible grid space larger than 4×4). An x/y accelerometer and an x/y gyroscope add some playful, gestural control to the device; most of the apps implement a “shake to erase” control and several respond to tilt in various ways.

It boots up into 7 different apps, though it has the potential to boot up into 16 total. This device is primarily a MIDI controller, but I’ve also written an app that allows you to pull the button and analog data into MaxMSP and to control audio.

With this project, I was interested in making a device that was a little more self-contained and relatively cheap to make (lots of buttons = lots of $). In keeping more with the concept of the tenori-on, this controller does all its app processing itself, it does not rely on a computer to process button presses/analog controls into MIDI. This means you can plug it directly into a synth or any device that understands MIDI and you’re good to go, no computer required. It runs off a beefy LiPo battery that keeps it running for days on a charge, so it’s fairly portable as well. In keeping with the monome side of things, it’s totally open source and can be adapted to your particular audio setup/needs. All the Arduino code is up on github, along with a MaxMSP patch that decodes data from the controller into something usable in Max.

Arduino Yún

 

 

During Codemotion Milano Stefano had a talk with Federico Vanzati from Officine Arduino on how to use a supercheap USB Audio card with Arduino Yún and test the full audio capabilities with zero effort, external libraries or mp3 shields.

After some days he came out with a quick tutorial that you can check out here (includes code!).

RadioduinoWRT – a do it yourself webradio

WK1600_DSC_0005_video

Raffael @ code-bude.net build a webradio by himself. It’s made from an Arduino, an hacked TP-Link WR703N router and some interface parts.

Today I want to present you one of my larger craft projects. This time it is not just about software, but also about the associated hardware. What is it? A web radio!

I like to listen to internet radio stations, but I didn’t want to run my pc only for listening to webradios. Connecting my phone to my stereo either wasn’t a solution, since I’d rather wear this with me, because I don’t want to run for each SMS / Whatsapp message to the music system. And because I always like to tinker, it was obvious to build a web radio as a standalone device myself.

MakerLab reviews the Arduino Starter Kit

arduino, audio, review, StarterKit, tutorial Commenti disabilitati su MakerLab reviews the Arduino Starter Kit 

When we released the Arduino Kit, we knew that we are equiping the closet-wannabe-makers to start planning for world domination. Now it has the stamp of approval from MakerLab too!

Make Noise With The New Arduino Kit is a project by Alessandro Contini (@CNTLSN) and Alberto Massa (@nkint)

The above video explores the basic components of the kit and things that a new-maker would want to start with, including a light controlled theramin, and by theramin, I really mean exploring every possibe way to make impressive noises from one simple experiment.

Sounds fun? Do write to us, what you made out of your starter kit. We may feature you next ;)
