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:

The following picture shows the master block-diagram of an L/S/E machine:

This reflects to the old versions of our interfaces. The new L/S/E suite developed by XBrain will use computer to do also the whole audio thing.

For your fair information, this image shows the graphic of the major ranges which have the greek letters as labels:
