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

31 10 2014

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.

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 »

Hypno-gogGles using bike lights

5 10 2014

This is a project made up from a cheap pair of old flashing LED-type bicycle lights that I rigged up to my plastic home made goggles, in order to try and induce a relaxed state of mind in such a stressful world.

Overall weight is not too much of an issue as both sets of lights are of a similar design, where each one runs on a couple of AAA size batteries which last a good while.

OCZ hack

4 10 2014

This makes use of the OCZ NIA (Neural Impulse Activator) advanced biotechnology games interface as an analogue to digital converter, by replacing the headband and just stuffing a small analogue signal in one of the inputs in relation to the reference (centre) connector pin.

This contemplated my DIY motion sensor project where only the RX diode signal is used.

Basic DIY LED motion sensor

2 10 2014

I used a couple of ordinary standard LEDs as a transmitter and receiver pair in the bottle cap which could be then simply be screwed on to the mask cup itself.

Eyelid movement could hopefully be detected by measuring the variations in the reflected light and maybe act as a REM sensor.

Ideally you would then amplify and process this analogue signal into a digital form.

Ganzfeld project

2 10 2014

This is a simple experiment based on the Ganzfeld effect in order to help induce visual hypnagogic hallucinations using coloured lighting whilst relaxed.

For this project a scrap tri-colour LED has been utilised in my sleep mask by fitting the component in the underside of the blue cap.

Project ‘Roxanne’

1 10 2014

This is another Halovision hack, except a lighter and a more sleeker webcam arrangement has been fitted to the mask cup via the blue screw cap.

A matching group of three red LEDs mounted in the cup have also been used to provide the background illumination for the camera itself.
