Moscow-based hacker artist ::vtol::, a.k.a. Dmitry Morozov, is back with another impressive project. His latest, called 2ch, is an interactive, pyramid-shaped instrument that enables two people to communicate via mind activity.

2ch consists of two NeuroSky EEG interfaces worn by both users, as well as two servo motors with a hall sensor and magnet, a two-channel sound system, a couple screens, and an Arduino. In terms of software, the instrument uses Pure Data and Max/MSP.

As Morozov explains:

The project is an instrument for communication between two people by means of visualising the electroencephalograms of two members, which are translated into sound, mechanical motion, and video images. Two participants should try to synchronize their minds, guided by the pitch of the tone, visualisation and movements of mechanical parts.

For Connor Russomanno and Joel Murphy, designing a brain-computer interface is not the stuff of science fiction, it is their day job.

Clara is a smart lamp able to respond to your brain waves and subtly adjust your environment. The project, running on Arduino Uno, was created by  Marcelo Mejía Cobo, Belen Tenorio, and Josh Sucher for a class at the School of Visual Arts in NYC (US).

The team worked with the Neurosky MindWave Mobile, a Bluetooth EEG-reading headset in order to wirelessly detect “attention” and map the lamp’s color temperature and speaker volume accordingly:

At first, the lamp emits a warm, comforting glow, conducive to idea generation and creativity. But as you start homing in on a specific idea, the light becomes crisper and cooler, and the volume of the ambient noise flowing from the embedded speaker slowly increases, enhancing your ability to concentrate and block out external distractions.

In the picture below you can see the inside of the lamp with the Arduino Uno and Adafruit Music Maker shield:

Have you ever wanted to turn on or off your TV just by thinking about it? We love this hack mainly because it uses an old Star Wars Force Trainer game. You can still buy them for about $40-$80 USD online. This cool little toy was introduced in 2009 and uses a headset with electrodes, and an electroencephalography (EEG) chip. It transmits the EEG data to control a fan that blows air into a tube to “levitate” a ball, all the while being coached on by the voice of Yoda. (Geesh! Kids these days have the best toys!)

[Tinkernut] started by cracking open the headset, where he found the EEG chip made by a company called NeuroSky (talk about a frightening sounding company name). The PCB designer was kind enough to label the Tx/Rx pins on the board, so hooking it up to an Arduino was a snap. After scavenging an IR LED and receiver from an old VCR, the hardware was just about done. After a bit of coding, you can now control your TV by using the force! (Ok, by ‘force’ I mean brainwaves.)  Video after the break.

Note: [Tinkernut’s] blog page should have more information available soon. In the meantime if you can find his Arduino Brain Library on github.

This isn’t the first EEG to TV interface we’ve featured. Way back in 2010 we featured a project that used an Emotiv EPOC EEG headset to turn on and off a TV. But at $400 for the headset, it was a little too expensive for the average Jedi.

Solaris is an interactive installation created by Julia Borovaya (idea curation), Edward Rakhmanov (robotic system, chemistry), Vtol (programming, electronics) with the help of Alexander Kaplan, professor of neurophysiology:

it demonstrates the field influence of the permanent magnet on the magnetic and spirit (fluorescent) liquids. Two liquids constitute the diphasic system. Due to liquids movements and their surfaces’ modifications we visualize the unique processes of human brain. The spectator wears on neuro interface Emotive Epoc, the device computes a brain activity and sends information to the installation machinery.

To test the project people of different ages, social groups and professional areas were invited. Test results confirmed that brain activity and mood of the man reflect on the dynamic and character of liquids movements in the sphere. Object reacts on the changes of mind and emotion states. People who spent a plenty of time with the object managed to influence the dynamic and direction of the liquids on the unconsciousness level. We also reveal that the installation visualizes the temperament of the person. The object copies your mental organization and echoes it on the liquid’s surface. The object becomes a part of the participant.

It runs on Arduino Uno controlling dc motors, 2 actuators and a custom digital motor control system interface.
