Things Left Unsaid

Concept Development;

For my final project, I took myself as the center of my piece. I did my research emotionally and I tried to see the difference between two cultures that I am living in. In the end, it took me to the point where I saw the American culture as dark space from my perspectively mostly basing it on the lack of support in-between friendships.

Audio Narrative;

In order to change my feeling in to words and share it with people, I decided to create an audio narrative. The narrative starts with the astronaut connecting with the mission control, and a small conversation between me and a good friend happens. The conversation is in Turkish and it is representing my voice and my home. Throughout the narrative we hear, space sounds, multiple effects and two songs by Pink Floyd.

Pink Floyd;

Why did I decide to use Pink Floyd’s music in my project? This year 2015-2016 school year has became the year, where I started getting more and more interested in classic rock , the spacey-journey alike songs of the group inspired me to develop a concept around myself.

Audio Narrative / SOUNDCLOUD

Video;

For the video of the project my main intention was to show the feeling, and I tried to explain my my feelings, the sadness and loneliness without using words. Almost a dramatic looking but at the same time the video has became an emotional translator of the concept.

OpenFrameworks;

OpenFrameworks is the last but not least important part of the piece. OpenFrameworks sketch helps audience to realize that the artificial and unrealistic aspect can be seen more and more realist under the circumstances of real-life events. In my OpenFrameworks sketch I decided to use the movement of The Sun, The Earth and The Moon, this daily event, made my journey a little bit more realist and reliable.

Arduino Robot

This guide shows you how to quickly and easily build an Arduino-based robot. Robotics is an exciting and fun hobby that has become very affordable in recent years. What would have required a lot of money and experience to do a few decades ago is now affordable, easy, and most of all, FUN!

Simple Arduino Robot

The parts used in this guide can all be purchased together in the Funduino UNO Robotics Kit, but you can follow along with a different kit just as easily as long as you have similar components.

Keep in mind that this tutorial shows just one way to make a robot — you’re limited only by your budget and imagination. If you want to buy more sensors, or a nicer chassis, go for it! The entire process may take an hour or two, so get ready to have some fun!

Arduino Project by Dheera Venkatraman

Posted on September 8, 2015September 8, 2015 Posted in ArduinoTagged Arduino, Technology3 Comments

MIT student Dheera Venkatraman has developed a new way for users to wirelessly unlock their doors with simple Google Now-like commands.

The Maker created an app — which is aptly dubbed “Sesame” — via Google Now that lets those adorning an Android Wear watch on their wrist to utter the words “OK Google, Open Sesame” to open a door. That is, of course, after the door is rigged with some “simple yet trivial” hardware.

To bring this idea to life, Venkatramann modded his door with an Arduino Uno (ATmega328), a Bluetooth module and a servo, which allows the lock to be activated via its accompanying app. The servo is attached to the door latch, while the Bluetooth module awaits a trigger signal and communicates with the Arduino over serial. Once the process is complete, the Arduino activates the servo to open the door.

Android Wear app lets you unlock doors by actually saying “open sesame”
