- Lately some companies have started selling goggles that have blinking
- white lights mounted in them in such a way that when the goggles are
- worn, there are a light shining into each eye. The lights blink in a
- left-right-left-right fashion so that one of the lights are always on.
- The frequency of the blinking are variable by turning a knob you hold
- in your hands. The goggles are used with the eyes closed so that the
- lights shine through the eyelids.
-
- Goggles like this has some amazing properties.
-
- First of all they produce strange visuals even when straight. They
- can be compared to the visuals one get by keeping a slight pressure
- on the eyelids with a finger for a little while. The type of visuals
- varies with the frequency of the lights. Low frequency gives (with
- me anyways) lots of swirling colours, while high frequencies gives
- what seems like millions of small dots on a red background. One very
- strange effect I get sometimes when I suddently raise the frequency
- is that the dots start to fly away from me at an incredible speed,
- while they are getting smaller and smaller and I can still se each
- and every one clearly.
-
- On acid the visuals get much better (surprise :) Although not as much
- as I had hoped for. A strange thing is that it gets much more relaxing
- to wear the goggles. This is because you don't notice the frequency
- so good. I suspect that when straight the pupils dilate and contract
- with the light, but on acid they don't. It also get's harder to find
- out what the frequency is because it seems to change all the time.
-
- The goggles also have other interesting properties. They can be used to
- induce different states of mind. By tuning to the right frequencies, the
- brainwaves can be manipulated into their alfa, beta, gamma or delta
- states. I haven't experimented with this though.
-
- Combined with a system that detects REM sleep either by monitoring
- brainwaves or looking at the eyes through the eyelids with IR light,
- they can be used to turn REM sleep into lucid dreaming sleep. I intend
- to try this out, but haven't gotten so far.
-
- The goggles has also been used with great success to remove or lighten
- migraine problems. In fact I think that's why they where invented in
- the first place.

-
- I didn't buy my pair of goggles, but made them myself. As only red
- light gets through your eyelids, white light isn't necesary. Red LEDs
- work very good. I mounted 4 of them in each glass in a pair of
- sunglasses, and made the controll unit with 3 small IC's (555 timer,
- 7474 flip/flop and 74244 line-driver). And this I put into a paddle
- from a C64. If there is any interest I can post a more thorough
- description on how to make them. The total cost of parts is about
- $15 I guess. I made my controller on experiment circuit board, but
- it you want to buy it, it would be no problem for me to etch real
- printed circuit boards ready for mounting the IC's on. The board
- would be about 3x3 cm in size. After mounting the IC's, a variable
- resistance and a condensator it would be ready to conect to the
- LED's in one end, and a 5V powersupply in the other. (Or 6V battery).
- I would charge about $10 for the board and posting.
-
- There is another a bit easier way of making the goggles. It involves
- connecting the LED's directly to the printer-port of your computer,
- and controlling them with a simple program. I did this first, but I
- didn't like it. I had to sit by the computer keyboard and press z
- and x to vary the speed, and the noise of the fan distracted me. And
- this won't work with all printer ports.
