LD Goggles Update


As it turns out, there were some elements of the wireless LD goggles that were less than ideal.

  • Drilling through plastic creates an unpleasant burnt-plastic smell
  • The entire device was heavy and bulky, thanks to the 9V battery
  • My current op-amp setup necessitates a 9V battery
  • 9V batteries are not cheap, and they seem to expire quicker than I would like
  • The mask leaves marks. Which can be fun to explain to co-workers the next day

To alleviate some of these problems, I have created a wired version that is lighter, and now powered by a spare wall-wart I found. Here is an updated picture, I simply routed the power the LEDs are receiving through a longer pair of wires.




I also made some changes to the Android app, to give more fine-tuned control over a few settings. The updated apk is available at the same location, here.

I never did talk about how well this thing performed, did I? It does in fact work. Or rather, it has worked. It incidentally works better than it actually works- allow me to explain. The goal here is to send a visible signal to the dreamer which will alert them to their dreaming state, while not waking them up. This sleep mask works in that capacity, but sometimes wakes me up. On occasion this has led to “false” awakenings, but more often it just wakes me up. Changing the intensity of the lights helps, but it is truly a fine line. Even when the lights are configured to come on a few minutes after REM sleep is detected, this can be an issue.

The majority of the time these LD goggles have worked has been due to my expectation of entering a dreaming state. Wearing an oddly-shaped sleep-mask makes for a very prevalent reminder all the while you are asleep, and I find myself realizing that I am dreaming even without a signal from the outside.

Truth be told, the quality of the lucid dreams I have experienced with this device has been rather low. Shallow. Short. Often interrupted with more flashing lights.

An improved version of this thing would involve:

  • Direct detection of REM, instead of how the Zen does it (I’m not even sure how it detects sleep phases, actually)
  • Eye-signal recognition, to turn the incessant flashing lights off, if anything
  • Low-power electronics. Because it’s totally doable
