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)

DreamNet: The programmable lucid dreaming headband

What have “What’s the frequency Kenneth?” and DreamNet the new lucid dream headband got in common?

Yes, you’ve got it… its R.E.M. Except we are not talking about the band, but rather the lucid dreaming headband; plus about the current trend which is currently rapid eye-movement detection.

Welcome to the party!

Synapse, the people behind their Kickstarter project are based in Los Angeles, California. They hope to raise $30k USD by February 19th 2014.

Bill Murphy the main person behind the project is the science correspondent for the Lucid Dream Experience magazine.

Bill is known in some circles as an onscreen TV personality. He is also an avid dream researcher who is a regular contributor to various magazines, blogs and radio interviews.

On the prototype headband currently 2 dry electrodes are used, which include the primary one at the front and one reference earlobe clip or mastoid point. This secondary electrode is used to reduce artifact noise from forehead muscle movements and electrical noise.

The hardware is based primarily around the Neurosky ThinkGear Am chip, whilst the software interface is based around the Lucid Scribe open source project by Michael Paul Coder.

Michael himself is an expert in this field of software and lucid dreaming.

Indeed some readers might remember he was one of the first to recognise the possibility that the Luci dream-enhancing headband was a big scam back in November 2013.

Lucid Scribe can be run in REM detection mode where it will play an audio file for example.

It is also noted that in addition to EEG and REM detection that EMG muscle potentials, eye movements, etc. could be detected via Lucid Scribe software.

Software will run on iOS and Android platforms. DreamNet will connect to your Smartphone via Bluetooth LE.

The DreamNet headband is now in competition with the recently funded Aurora dream-enhancing headband.

Both use NeuroSky based technology, except the Aurora has all the hardware integrated in the headband itself. This is a major advantage providing size, weight and comfort issues are addressed.

Thus the Aurora can run independent of any computer or smartphone whereas the DreamNet cannot.

Currently there are 38 days to go. Synapse have already raised $2,078 USD of the $30k needed to fund the project.

Backers can buy a discounted DreamNet for $140 USD with $25 USD for shipping outside of the U.S. as a limited offer here.

Shipping of the units is expected in June 2014.

However for people simply wanting the obligatory t-shirt or a sticker then you might be a little bit disappointed.
