Updated the firmware with the pixel diff part of the halovision algorithm running fast as lightning in C. My trusty lab partner helping with a quick calibration test.

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.
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.
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!
[Michael] has been working on projects involving lucid dreaming for a long time. The recurring problem with most projects of this nature, though, is that they often rely on some sort of headgear or other wearable which can be cumbersome to actually sleep with. He seems to have made some headway on that problem by replacing some of the offending equipment with a small camera that can detect eye movements just as well as other methods.
The idea behind projects like this is that a piece of hardware detects when the user is in REM sleep, and activates some cue which alerts the sleeper to the fact that they’re dreaming (without waking them up). Then, the sleeper can take control of the dream. The new device uses a small camera that dangles in front of an eye, which is close enough to monitor the eye’s movement. It measures the amount of change between each frame, logs the movements throughout the night and plays audio tracks or triggers other hardware when eye movements are detected.
[Michael] is looking for volunteers to provide sleep logs and run tests, so if you’re interested then check out the project!

Added support for the halovision headband (Halograph EOG). The one we have all been waiting for. A headband with a NoIR camera that measures the amount of change between each frame from the video stream.
It should still work with ordinary webcams, so give it a spin now to see the magic in action:
Introducing release candidate one. Camera up and filming the real world:
Camera down…
… deep down, recording eye movements:
Non-invasive, light-weight and as comfortable as it gets.
