I’m building a dream mask that uses EOG based on arduino. It has a configure mode where there is a menu driven configuration over serial, and output mode where EOG data is sent over serial. It has autotuning for the EOG amps, variable LED brightness/flash sequences, configurable “fall-asleep” delay, “TWC” (can interact with it via eye movements like remdreamer), post-REM wake up alarm and a regular alarm clock.
It’s still a work in progress on a breadboard right now, but its promising. Graphing the EOG data is really cool, I hope to replicate some of LaBerge’s experiments. This is a graph of a nap I took a few days ago. The EOG is still kind of noisy, I hope to clear it up with more filtering. I am just using disposable EKG electrodes for now.

Above 500 is an eye movement to the left, and below 500 is an eye movement to the right. Thats about 3 hours squished together, in the software I can zoom in on specific areas. I still need to add timestamping to the graph.
This is how it looks so far:
