• Disable the "Adaptaptive Brightness" feature on your phone.
• Adjust the brightness on your phone until you find what is most comfortable for you.
• Temporarily disable notifications on your phone, so you won't be interrupted during your session.
• Install an app that will keep your screen on. For example, install the Screen Alive App from the Google Play Store.
• Connect your headphones to your smartphone.
• Completely recline in your favorite recliner chair.
• Press the blue start button, which starts both flashing and music on most browsers.
• Put your smartphone in either a virtual reality headset, or a custom headset described below.
  Alternatively, you could simply relax in a dark room and put a phone or tablet close to your face.
• Close your eyes.
• Press anywhere on the screeen to stop the flashing.

Virtual reality headsets work well, but this custom headset is a little more comfortable than the virtual reality headsets I tested:

• The custom headset is 3D printed
  • 
  • 
  • Find someone who can 3D print these custom parts for the main body and front plates. I use OCpartsupply. Download the .stl files.
  • Purchase the Elastic Bands for Wigs and Foam Face Replacement Face Cover Pad
  • Purchase six #4-40 x 1" pan head machine screws, and six nuts
  • Purchase 3/4" wide velcro strips. You will only need to use the "hook" or "prickly" side of the velcro.
  • Follow the assembly instructions below.



• Assembly Instructions for Custom Headset using 3D Printed Parts:
  • Cut each strap in half. Feed the straps through the slots. Use the front slot for your phone, back slot for your head.
  • Secure the two most outer plates with the two machine screws and nuts that protrude outward, as shown in the picture above.
    These screws will support the phone, along with the velcro straps.
  • Secure all of the plates to the main body using the remaining machine screws and nuts.
  • Cut some 3/4" wide velcro strips ("hook" or "prickly" side) so that the velcro fits on the top and bottom rim of the main body.
  • Attach the face cover pad to the rim of the main body. The face cover pad will stick to the velcro.
  • Adjust the straps if necessary. Trim the excess strap once you are satisfied with the fit.
