Deepaks a real punch

22 11 2014

The latest Lucid Scribe plugin for use with the Wild Divine Lightstone is now available thanks to Michael.

This will give my project more flexibility due to the lower threshold now offered, without having to modify the hardware or increase the LED light output to otherwise gain the extra reflected sensitivity.

This doesn’t make the previous version of the plugin redundant however.

On the contrary, this now gives me the extra option of tailoring the sensor design further should I wish to, including the idea of maybe swapping the photoresistor for a suitable photodiode instead.

The latest Lightstone IOM v0.9.9 plugin is now available from Lucidcode here.

Lightstone hack – update

16 11 2014

This follows on from my previous post about the Wild Divine Lightstone where I have included more detail about the sensors themselves in relation to my DreamJacker mask project.

I have now also utilised a suitable IR led from an old remote control to act as the transmitter in order to reflect the light off my closed eyelid and back on to the photoresistor. This signal is then fed to the Lightstone interface which acts as an analogue to digital converter with hardware connection to my computer via a short usb cable.

Lucidcode do already have a suitable plugin to monitor the heartbeat and GSR (Galvanic Skin Response) by using the standard finger electrodes originally supplied with the Lightstone, including software intended for the later IOM versions.

However Michael kindly updated the plugin by adding the necessary code to create a new channel ‘IR LED REM’ which is especially intended for this project. (Lightstone IOM 0.9.8)

Romancing the (Light) Stone

This is a hardware hack idea for the Wild Divine Lightstone in order to detect (REM) eye-movements via a light-dependent resistor or photoresistor.

Background

The Wild Divine Lightstone is basically a biofeedback, or more correctly, a human/computer interface for reading biosignals, etc.

The Lightstone hardware is bundled with The Journey to Wild Divine package for use on your home computer along with the manual, music and software disks.

It also features Deepak Chopra. Read the rest of this entry »
