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 »





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)
