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:

The first printout that I recorded last night, 5 minutes past midnight, shows the strained beats picked up by the halograph FM. The fREM channel can be seen counting up each blink or strained beat that peaks over the top line and then triggers the next track in the playlist after the 8th blink.
And the second printout, recorded at 0017, shows the same thing happening with the OpenREM channel from the OpenEEG electrodes.
This will make it a lot easier to perfect the algorithm by highlighting where it was thinking about triggering. The tracks at 0618 made it into the dream and helped me stave off a hoard of zombies, but didn’t trigger lucidity…

The eight waves in the minute featured above seem to have repeated every hour, around the 50 minute mark, starting at 2 am. The relative quite in the accelerometer channel suggest that the waves aren’t artifacts. I might set an alarm for them one day.

The algorithm didn’t trigger an audio track, as it was looking for multiple events like this in a row. I will update it to optionally trigger on only a single event, because of the vividness of the dream. The spike looks similar to when I open my eyes while awake.

I woke up at 0841 right out of a dream.

It took forever to fall asleep because I was just too excited. I woke up at 0534 from a dream and noted the time. The printout of the minute I selected is from 0515 and shows some very distinct patterns that are similar to when I move my eyes around while conscious. I will use that as a base to write the REM-detection algorithm that will trigger the audio tracks.
I embedded the four active electrodes inside a headband and taped the passive electrode to my earlobe with some duct tape. I still need to meditate on a more convenient way to attach the passive electrode.
It can be worn with the sensors on the forehead by the Frontal Lobe to trigger on the spikes in electrical activity caused by eye movements or at the back to monitor the brainwaves by the Occipital Lobe where visual perception is processed. Check it:
