Some small updates to the INSPEC design – it now has a built-in battery and a flex cable as the proximity of the LEDs was interfering with the image quality.

Added facial detection so that it only looks for movements within a region where a face was detected.
The file haarcascade.xml can be replaced with one of these or a custom cascade classifier for better performance.
The latest version of the Halovision device; code-named INSPEC. A standalone infrared camera with a processor powerful enough to run the latest machine vision algorithms that flash LEDs when eye-movement patterns are detected after a long enough still phase. The camera case is 3D printed and installed on a flexible tripod to get a good angle. It records GIFs along with BMP stills that can be viewed the next morning via micro-USB cable.
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.
