I have had a few inquires about using the setup without the headband and this shows that it could work if you can sleep close enough to the night-table or have the camera mounted above the bed somehow. I will try to record a session like that one night…

I now have an infrared LED shining down on me from a cupboard… and the recordings have been out of this world! Gone are the dark ages with just a few squiggly lines of questionable EEG signal quality.
The latest version of the Halovision plugin records an image-stream of any movements and Lucid Scribe automatically replays them when reviewing a session. This helped a lot with writing filters for the artefacts, like when the camera re-focuses.
The eye movements that triggered the audio track can be seen in the minute above. I was re-taming a hippo that I had saved as a baby in another life!
Here is the finalised release candidate of the Halograph EOG – a headband with a night-vision camera held in place by two bendable selfie-sticks:
It is more comfortable to sleep in than I had ever hoped. I can sleep on either side or on my back with complete freedom of movement with the 2 meter cable.
The age of light is nigh; this is light-bending!

And then from the halograph FM channel at 0333:
Lost signal with a false positive at 0411:
That should be enough for me to add a signal quality channel and avoid false positives.
Caught a nice flight of stairs from the OpenEEG channel in the minute below.
The signal quality tapered off here and there after that, which can only be seen in the raw EEG data… will add a signal quality channel to keep track of it.

An interesting change in the heart rate variance in the top-right corner that might be indicative of REM sleep:

An exercise I picked up while practicing Bujinkan. The first printout shows four deep breaths a minute:
The second printout shows the rapid “shining” breaths, 60 inhalations and exhalations in one minute:
Notice the effect on the EEG channel. It feels exactly as pictured above. Although I have suspicion that a change in skin conductance (GSR) might be causing some artifacts. Perform Kapalabhati thusly:
Sit in the Lotus posture if possible and hold the head erect. Begin with an exhalation brought about by a rapid inward stroke of the abdomen. Inhalation follows immediately by relaxation of the abdominal muscles. Thus, inhalation is passive and automatic. Repeat this exercise at the rate of one exhalation per second. Look up at the end of the exercise, exposing the throat and hold the breath with the diaphragm.
Previously it was specified that the Lotus posture of yoga be employed for this exercise. The reason will now become apparent. When the breathing exercise described herein is properly performed over a long period, certain vibrations begin within the body. The vibrations, coupled with a feeling of exhilaration, lessen motor control of the limbs. In the Lotus, the legs are in a position impossible to undo without the aid of the hands.
This exercise is used to develop concentration.
Do not attempt while driving or operating machinery!

I now have the current-stimulation delivery system smoothed out to where it only zaps for one minute and waits at least ten minutes between doses, and finally managed to sleep through without interruption. Still no lucidity, but I had exceptionally vivid and long dreams again.
