As said a Brain Machine is composed of 3 main parts which could be considered completely autonomous (from the electric point of view).

ELECTRONICS:

This section is handled completly by the software, which provides a stereo output with two synth. In the first version of software we created a precalculated sinusoidal wavetable. In some softwares the wavetable is calculated once per cycle, stretching it basing to the frequency.

PROJECT PURPOSES:

It is important to coadiuvate the effect of the light stimulations in a matter that work synergically with the first one.

Main target of the project is to reveal some interesting aspects of the low-level interactions between some computer-controlled human interfaces like Light and Sound machines (aka Brain Machines) and human itself. These devices provide a way to stimulate our self-controlled states of perception and to manage them using simply a Light, Sound and Electrical pulses in a isolated environment.

The first hardware interface was codenamed B-Storm, engineered and built by Xi/bRS. It featured:

1. Linear amplification of a BF signal
2. Analogic Mixer for BBF and external sources
3. 6-bit Light switcher
4. 1-bit TTL pass-thru

This part is achieved with Hi-Lum 3cd bright LED (Light Emission Diode). In the B-Storm there were 3 LED per eye, 2 bright red, 1 green. This latter leaded an insufficient radiation. These LED were displaced as the figure shows:

Here's the picture of the first stable release of the CES:
