PSG Step 5: Getting off the SD Card

As mentioned, since recording for long periods over bluetooth is pretty risky, it makes a lot of sense to record onto the extremely stable micro SD card. The main OpenBCI SD Card Tutorial covers the basics of formatting the card and recording, and the process is very straightforward. However, in order to be maximally efficient, […]

Polysomnography Step 4: Recording!

Ok – I’m wired up, everything is connected to my Cyton board – the time has come to actually record something. This is pretty much exactly the same process you use for any kind of Cyton activity, but I’m going to repeat the steps provided on the OpenBCI site for my own sake and to […]

Polysomnography Step 3: The Cyton Board

Obviously anybody who has a Cyton has at least done the introductory tutorial provided on the OpenBCI website, and this part doesn’t really require much explanation. There’s also a decent introduction on “The Autodidacts” website, demonstrating how to set up basic ECG using OpenBCI.  But again, for the sake of documenting the process, here is […]

Polysomnography Step 2: Electrode Placement

Understanding biodata measuring: I am still very far from having mastered the details in this area, but here’s my non-specialist sense of what is involved in getting data from a subject’s head. The key point to understand is that all of these measurements are COMPARATIVE. Electrodes are not like a thermometers, which measure the temperature […]

Polysomnography Step 1: Gear

Here I’d like to record the process I’m using to record PSGs and collect my own data for dream realization projects. It is worth repeating that I am an average Joe with zero technical training in polysomnography, bio-scanning, electronics, computer programming, any of this sort of stuff. I’ve never played with an “Arduino”.  I’m a […]
