Wearable tech project by Ylenia Gortana is a jacket that functions as an electronic music interface. The work is a collaboration with New York musician Birdmask:

In developping the concept of “Soundable Fashion” I started from the point of questioning myself to come up with alternative ways of presenting fashion other than on a common catwalk.

… The whole jacket is built with different layers of conductive e-textiles, which are arranged in a matrix of 52 handmade, square push sensors. The layers are basically a copperthread layer and a silverthread layer which are seperated through a velostatic foil which gives the sensors the ability to not only have an on/of position but also a whole range of signals to read in.

The sensors are connected with a lasercutted copperfabric circuit on the lowest layer of the jacket. The circuit ends in two Arduino Lilypad boards which are connected to a bluetooth signal board which in turn communicates with the computer. The bluetooth board (Bluesmirf)  sends the analoge data via firmata code through Arduino to the Pd programm where the data gets converted in Midi Signals.

With Action Cam

新MacBook(12インチRetina)は USB Type-C と3.5mmヘッドフォンジャックの2個しかポートを搭載していない.電源もUSBポートから供給する.

USB Type-C もエンジニアリング的に興味深いのだが,3.5mmヘッドフォン端子のほうもなかなか面白い.


アップルヘッドフォン端子は4極のTRRSと呼ばれるタイプで,プラグ先端(Tip),第1リング(Ring 1),第2リング(Ring 2),スリーブ(Sleeve)という構造になっている.





iPhone付属のヘッドフォンマイクには3個のボタンがある.再生・停止・スキップ・バックを兼ねるボタンがひとつ,ボリュームアップとダウンがひとつずつである.iPod touch や iPod shuffle に付属するヘッドフォンにも同等な3個のボタンがある.






この記事によると,リモコンはプラグインパワーからもらった電力で,プラグされたときにマイクライン(スリーブ)へ音声信号(というか超音波信号)を返している.iPod shuffle 4th Gen 付属のリモコンの場合,280kHzを1.5ms返し,その後244kHzを4.6ms返している.これによって,プラグされたリモコンを識別しているのである.

7E Guest Artist - Yann Seznec

Our engineering/art blog started summer of 2013 that focused on our passion and profession; art, music, technology and electronics.  What started out as intimate projects that revealed our relationship/marriage has now flourished to wide variety of guest artists from all over the world.

Yann Seznec is an artist, musician and founder of Lucky Frame based in Edinburgh, Scotland. His work focuses on sound, music, physical interaction, games, and instruments.

His recent work top to bottom:

Currents is a project that is both installation and performance.  It consists of 172 computerized fans of varying sizes.  The fans access weather data from 6 varying global locations and recreates wind patterns for the visitor.  

Spores is an installation that shines laser underneath mushrooms to clearly highlight thousands of glistening spores. 

Cigar box MiDI Controller is a playful project that includes 6 potentiometers, 6 buttons, 3 toggle switches, a Gametrak string controller, and a breakout board for five capacitive touch note switches.

Thank you Yann for joining 7E!

Thrustmaster Score-A Controller Review: A Serviceable Gamepad That’s A Few
I have been hunting for an ideal Android game controller for a long time. I’ve tried tons of them: tiny, retro, travel-oriented, and full-size. None have hit that perfect combination of portability and utility (for as much as “utility” can be applied …
