Dreams We see them every night, but do not always remember them. The most vivid dreams come in the fast phase of sleep. For the first time after falling asleep, this phase begins in about an hour and a half and lasts a little less than 15 minutes. The duration of each subsequent phase increases and in the morning can reach a couple of tens of minutes. If you wake up in the fast phase, then you will be relatively awake and for the first few seconds you will remember your last dream.
An ordinary dream can be compared to a movie, and a lucid dream can be compared to a video game, where you not only see what is happening, but can also take part in it. In such a dream, you can make decisions yourself, think, write poetry, make plans. In general, this is a whole mountain of good time, because time in a lucid dream goes ten times slower than real. You can defeat the dragon, save the princess, write a poem about yourself, make friends with the prince and even play football with him, and in real life the clock will move only 2 minutes ahead. You can also wake up at any time as you wish.
It turns out that a lucid dream is walking along the border between the REM phase and wakefulness.
There are several ways to get into a lucid dream.
All of them are united by the fact that in a dream you must realize that you are sleeping and what is happening around you - it is unrealistic that everything happens in your head. You can fall into such a dream with the help of hypnosis or long training, or suddenly losing consciousness (for example, due to a lack of oxygen). But there are technical solutions that we will talk about today. During the REM sleep phase, you can give yourself a sign by which you will understand that you are sleeping (blinking lights).
There are several ready-made solutions on sale. For example, such glasses. They are set on a timer and arrange a small light show in front of your eyes.These glasses are worth as much as 5000 rubles. They are made of only 6 LEDs, a microcontroller and a battery. It sounds like it's very easy to repeat yourself. Well, let's get down to making exactly those glasses.
We will need
1. Any mask for sleeping
2. Arduino nano
3. Any six red LEDs (namely red, because red light is easiest to break through the skin)
4. Each LED needs a 220 ohm resistor
5. 9 Volt battery with arduino power connector
Let's get down to manufacturing!
Step 1
First, circle the glasses on a piece of paper, and then draw the same inside, but only in a smaller version (so that the resulting piece of paper can fit inside the glasses). Cut out. Now we mark the center of our eyes and select places for the LEDs in such a way that you can see each of them pressing the paper to your face.
Step 3
To put a piece of paper in the mask, it must be opened.
Step 4
At each hole we make two holes (for the legs of the LEDs). After that, we stick all the LEDs with the plus foot in one direction. Spread the legs of the LEDs. For reliability, each LED can be fixed with hot-melt adhesive. Now for hot melt adhesive to the very center we glue arduino (USB output to the top)
Step 5
We solder the whole thing as in the diagram. We solder the digital ports (3,5,6,9,10,11) through the resistor. Now we solder the ends of the resistors to the LEDs. To avoid the danger of a short circuit, fill it with hot glue. Then wires connect all six negative legs of the LEDs to the arduino ground. External power is connected to the vin and gnd ports. The electronic part is over.
Step 6
We put all the electronics into a mask and sew it up.
Step 7
As for nutrition, it is languid to sew a battery with a mount directly to the mask.
Everything, glasses for lucid dreaming are ready! It remains only to connect them to the computer and fill in the firmware.
A little bit about the firmware:
Glasses consume approximately 22 mA. With such consumption of glasses with a battery, 1 Ah is enough for about 6 nights of work. Ready firmware code can be downloaded:

That's it! Thank you for your attention and good luck with your dreams!
