Rolled a new Lucid Scribe plugin that monitors and records the EEG data from the Hypnodyne ZMax and triggers audio tracks when electrical activity from the eye muscles is detected during REM sleep.

I bent Lightened Dream to work on Mac!
Follow these instructions to see if you can get it running. Should be pretty simple even for a novice.
There are still some glitches, but I believe I got the worst of them. If there is any interest and errors are getting in the way, let me know and I will see what I can do.
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.
Optical wireless mouse prototype
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.

I have been getting better results with a different night-vision camera with built-in infrared lights and zoom:
Finally have the standalone version ready for some test runs on my beautiful wife!
Updated the data directory move to enable migrations across volumes.
Weeded out some more false negatives – if there is a large movement, it waits 10 seconds before counting eye movements again.
Tweaked the algorithm to weed out some more false negatives.
Improved the algorithm… it was missing REM episodes where the eye movements stopped for more than 5 seconds before the stairway to heaven was reached.
Episodes like in the following minute, where there is a 10 second break in eye movements around the 30 second mark, will now keep counting and trigger the audio tracks:

Ensured that the video feed is always top-most.
