Wireless mouse to eye mask modification

20 05 2017

Followers and readers of my blog may well remember my previous optical mouse hack for REM eye movement detection and lucid dreaming back in August 2014. That project known as DreamCaptcha relied on a direct USB connection to a nearby computer. Hopefully after having a bit more time I can now move on from that limitation by experimenting with a wireless mouse set-up instead.

The layout and construction is very similar to the earlier USB mouse hack. In fact I kept the milk carton shell and the elastic as before. Even the white tack to temporarily hold the base in is taken from that project era. However there were obvious benefits and certain obstacles to overcome during the whole modification process, most of which included the weight and power considerations, amongst others.

Halovision – dream like a boss!

28 01 2016

Michael of Lucid Code has refined his own REM detection system project known as Halovision which is great news for us interested in sleep and dream research.

The device measures subtle electrooculography (EOG) muscle changes by means of a small 5 megapixel camera over the eye which records your eyelid movements digitally frame by frame via your associated computer device. Read the rest of this entry »





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

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.

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 »





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.

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.
