the cheapest, easiest to build dream goggles EVER!

#123

I’l admit I know almost nothing about electronics and all that but i had one idea:

  1. get some cheap or old headphones.
  2. Cut off the heads of them, so you have the jack and some wire.
  3. (this is the part that I don’t know is posible) attach the LEDs to the end of the wires
  4. Plug it into an alarm with a headphone jack, so long as it will turn itself off, or not if your fine with flashing lights.
  5. If this works as i think it might, the leds should start flashing.
    Sorry if this idea’s already been posted or if its complete nonsense, just thought it worth sharing :happy:
    EDIT: Another idea: Might this be more effective if only one eye is shined on? We’re used throughout the day to seeing things with two eyes, if in a dream you say a flash of light, but it was only half there and sorta flickery like it would be if you say it only with one eye it might be more noticeable.

i have done this once… yes it is possible to do this. however you will need to dis essemble the alarm clock radio and solder right into the wires connecting to the speaker. the music playing through to the leds has the voltage that is moderate… it changes… causing the leds to flickers dim and bright… etc.when i did mine… i poked a small hole in back of radio to feed the wires from the speaker to the leds.
set the alarm to a certain time… and u might get the lucid dream you.ve been waiting for. the only bad thing about this option is it is considred a hit or mis.
meaning you could go weeks before it happens mainly because the is not way to tell if your rem sleep will happen at the axact time you set. but it is the mose in-expensive way to go. one thing you need to look out for… is the head phones.
the headphones in production today have a webbed fiber type wire… it is very very difficult to cut and splice. your best option is to look for cheapest oldest headphones you can find… like garage sales, pawn shops, odd lots… etc. because that type is older style wire… that has plastic coating. it worked for me… im sure it’ll work for you… and no, you dont have to be electronic savy to do this. give it a try. i myself never had any luck with it… thats y im trying the mouse trick… because the sensor in it will be able to detect my eye lids moving during rem.

been very ill latley; in and out of hospital… so havnt been able to complete the mouse eye ware. but soon, and ill let u all know how it goes.

Hey everyone, just thought Id mention something interesting I just now managed to do. I got a “bus pirate” for christmas(google it/look on hackaday, its a sweet tool) and managed to take complete control over an optical mouse sensor. This is nice because it means I should be able to(if I ever get a chance) interface the chip directly with another microcontroller and completely remove the computer from the equation. Admittedly this isnt as easy to do as just strap a mouse to your face, but it also has much greater opportunities for customizing and perfecting a smaller, more portable, accurate, and comfortable design.

rw43068- I hope you recover quickly from whatever illness you had.

I’m building a dream mask that uses EOG based on arduino. It has a configure mode where there is a menu driven configuration over serial, and output mode where EOG data is sent over serial. It has autotuning for the EOG amps, variable LED brightness/flash sequences, configurable “fall-asleep” delay, “TWC” (can interact with it via eye movements like remdreamer), post-REM wake up alarm and a regular alarm clock.

It’s still a work in progress on a breadboard right now, but its promising. Graphing the EOG data is really cool, I hope to replicate some of LaBerge’s experiments. This is a graph of a nap I took a few days ago. The EOG is still kind of noisy, I hope to clear it up with more filtering. I am just using disposable EKG electrodes for now.

Above 500 is an eye movement to the left, and below 500 is an eye movement to the right. Thats about 3 hours squished together, in the software I can zoom in on specific areas. I still need to add timestamping to the graph.

This is how it looks so far:

#127

I got the circuit and software completed and it works great. I also found a company that was willing to send me a couple samples of some nice reusable electrodes to use with it.

#128

I’m impressed. :grin: I must say congrats on seeing all your hard work come together. I look forward to any schematics/code you may release. Now you just have to perfect it/shrink it down. Out of curiosity, what language is your computer software written in?

Once again congrats on successfully piecing this together and good luck in continuing development.

#129

Hm, nvm. Just noticed that you had a more in detail thread elsewhere. Hope you don’t mind my posting a link to it here so others interested in knowing a bit more details about it can have a look. arduino.cc/cgi-bin/yabb2/YaB … 67726728/0

looks good so far. I look forward to seeing how it evolves.

#130

Thanks. On the PC side I just use Minicom to configure the settings over serial, and use KST to graph the output data. The code for the microcontroller is written in the Arduino IDE. I’ll be writing a standalone app for it probably in Java

Next step is to see if I can get it small enough on a PCB to comfortably fit on a sleep mask. I’d like to use what I have but I may have to switch to surface mount components to get it small enough, will have to see. I’ll post updates as I go

#131

Very nice. Surface mount components really aren’t that bad and I believe you mentioned on your other thread you sampled most of your components so its not like it’d cost much (if any) more money. Would definitely be able to shrink it down that way(especially the avr).

I’ve done quite a bit of PCB and Java work. While its obvious you are perfectly capable of managing this project on your own, if you ever want a second opinion on anything feel free to PM me.

Good luck, and I look forward to the updates.

#132

Awesome work!!! way to go, this is totally amazing.

Any new updates on this merkzu???

I was just reading about the zeo the other day and was really hoping someone could make such a device for lucid dreaming.

I got some questions for the creator

Why did you choose to track the eye movements through the temple and not the frontal lobes?

The zeo personal sleep coach tracks the frontal lobes which are located on the forehead using foam pads which you don’t need to use any gel. They said their tech which they call softwave is patented and is based on polysomnography which they say is the most reliable way of detecting sleep cycles including REM and that this is what they use in sleep labs all around the world.

The zeo is a wireless device that communicates on the 2.4mhz band, the zeo alarm clock has an sd card which all the nights sleep data is recorded onto which can then be viewed by inserting it into a PC.

Once you have this device able to be mounted into a sleep mask would it then wirelessly communicate with a PC?

Can you not make a console that communicates with the headband wireleslly without needing a computer by your bed?

I see that your headband has the same tech like the remdreamer which is TWC for two way communication. The remdreamer has just got this new upgrade out which is a rem speaker that can work with TWC do you think your device could support this, the remspeaker allows you to record an audio clip which can be played when the rem sensor detects that you are dreaming.

I would love to see this device of yours being able to have the following features

wireless
TWC
light and beep cues
audio cues
console with microphone for recording audio cues (so no computer needed)
4 LED’s for each eye, a light and sound machine upgrade for the future that could get your brainwaves ready for lucid dreaming. This is what the dreammaker pro has. Maybe we can forget this feature.

Anyway if you could have all those features and maybe or maybe not the last one then that would be so awesome.

I would love to see you building these as a complete unit and as well offering the flashed chip and parts for people to build it themselves.

Awesome and please keep up the great work, this is amazing work that really has got to be finished. The best idea I have seen in many years.

Thanks very much for reading

Hey honeyjigga,

While I obviously can’t comment on the work that merkzu has done, I would like to address some of the things about Zeo and possibilities for merkzu.

I may be getting to work with Zeo soon and I’d suggest you keep your eye on it for exciting improvements. Zeo uses the headband on the forehead for several reasons. It is the most comfortable way of arranging it without covering your eyes (not everyone likes a sleep mask). They also are primarily using EEG and want to monitor all sleep stages, not just REM. As such they are more focused on monitoring your brainwaves. That being said, if positioned correctly I’ve been told that EOG can be seen as well.

In terms of improvements to merkzu’s design. I think everything you listed is certainly possible. For wireless communication: either you could use a simple (but expensive) bluetooth protocol, or I’ve actually been working with some cheap microcontrollers with wireless built right into them. Light cues are easy. I would suggest that for the audio…instead of having a microphone with recorder(though certainly possible), a mp3 decoder with a SD card slot would be much more adaptable. Record/edit/pick a song you like, load it on the card, and you would be good to go.

I definitely think there is a market for this kind of thing…and have been working on general ideas in my head. Wish I had more time to work on a prototype of my own.

#134

Many thanks for taking the time to reply

the cheap microcontrollers you mention seem a good way to go for wireless. The sd is interesting but i wanted to completely eliminate the use of a pc. like the remspeaker from the remdreamer it has a microphone. I think the idea of an sd card would be greatr as well for putting audio like you said on it but also to record all sleep data on to it for playback on a pc like the zeo does.

I don’t understand how your getting to work with zeo soon, i thought it’s a closed system and so that means the makers are not going to release their sdk?

i was googling and found 2 other rem devices one of them a piece of software for an iphone and the other a wrist watch rem device. perhaps we could adapt these into a sleep mask type device.

#135

Glad you liked my suggestions. I’m not sure how easy/hard adding a microphone aspect would be, but it is certainly possible. I like the idea of using the SD card for data storage as well.

Yes, Zeo is currently a closed system…but I may be getting a chance to work with them regardless. I’d keep an eye on them for the next year or so for many improvements. From talking with them I know that they are a great company eager to listen to and help out their users.

The problem I have with the two sleep detecting devices you cited is that they are pretty inaccurate. They use body movement to detect a general idea of how awake you are. One of the most exciting things about merkzu’s design was that it has direct access to actual eye movement. This allows for things like signaling in your sleep back to the real world. I also personally think EOG is a more direct and reliable method.

#136

Coming to think of it now I too do believe EOG to be more accurate and it would be more affordable as those 2 links I provided require an iphone as well. I have created a post in this sub forum where I have some pretty incredible ideas which I thought deserved a new thread. If the ideas could be implemented into a new type of LD sleep mask it would be revolutionary, I am currently typing this up and will post the link here.

#137

here is the link to my write up

[Revolutionary idea for documenting a dream within a dream!!!)

Please post replies in that thread

#138

Anymore updates on this?

I believe this is very possible. I looked into some mini wireless optical mice and found them costing under $15 on amazon. The dimensions are 9.5CM x 5.5CM x 3.5CM that’s pretty small. Once you remove the plastic casing and get right down to the PCB you could easily fit that snugly in a sleep mask and it would be light and small enough to be comfortable to wear during sleep. This really is an excellent idea and even with this we can do two way communication like the rem dreamer. Of course we would need a PC by our bed but it could probably be modified to work without one somehow, possibly even work with a mobile phone which nowadays we all have.

#139

Removing the computer from the equation is easy with many mice. The mouse sensor most commonly used uses a pretty standard protocol, i2c if I remember correctly, and thus is easy enough to communicate with using a microcontroller, though this will remove some of the simplicity of this solution. The main problem I’ve had with this idea in the past is that the stock lens used in most mice have a very narrow range of focus, requiring you to keep it at a constant short distance from your eye. A different lens could probably be used, but then, once again, we are removing some of the simplicity of this solution.

#140

yes but if we go down the route of a mini mouse then the PCB is obviously smaller, and a lot of mice have unused space left on the PCB, so you could cut away that which should make the mice even smaller. Then as it is already a mini mouse you could probably get it very close to the eyes. Well that’s how I imagine it. Couldn’t we even desolder the components and resolder onto a strip board that’s precut to the required shape to get the stock lens very close to the eyes? or what about cloning the mouse, buy the exact components of that mouse and soldering them to a stripboard or working a prototype first on a mini breadboard?

#141

In my experience the problem isn’t so much getting it small enough to be close to your eyes… it is getting it to stay(comfortably) the correct distance to get reliable readings. Tighten/loosen the mask, move in your sleep, etc, could easily shift it enough to get inaccurate readings. Also, in terms of cloning the mouse…I believe for the cost of the parts to duplicate the mouse, admittedly not that expensive, you could create a better more accurate method, such as what merkzu was working on.

#142

With goggles that also allow the lucid dreamer to signal back to the device (such as the new REM Dreamer and NovaDreamer) , it is possible, with the right mask/software and a website controller program (such as multi-player game sites and chat sites use), to coordinate two or more LD masks with computer connections and allow very simple communication between dreamers; a multi-player dream game, if you will.

The ingredients for multi-player lucid dream connectivity are:

  1. A lucid dream cuing device such as a dream mask or audio device with dreamer response detection and interpretation.
  2. Computer software (LD program) that has two-way, real-time communication with the cuing device.
  3. Computer software (LD program extension) that has two-way, real-time communication with a remote host site.
  4. A multi-player host website program that receives input from the LD programs and issues messages to them.

Here are a few scenarios that could be fun for dreamers in a multi-player environment:

  1. Two players register and log onto the LD multi-player website, selecting the other player to communicate with that night and which player is to be the guide player (first dreamer cued). The respective local LD programs monitor the eye movements during the sleep of the players and upon REM detection send a message to the website that the respective dreamer is in REM; the website host program waits for both players to reach REM, then the host sends a command to the local LD software to signal the guide dreamer via audio/visual cue that she is dreaming. When (if) she becomes lucid, this lucid dreamer now signals (via eye movement) the mask/program to stop cueing and, in addition, send a message to the host program to notify the other dreamer that he is dreaming by audio/visual cue (could even be a pre-recorded audio cue in the guide’s own voice). The signal to the recipient’s to become lucid is now coming directly from the guide dreamer and may carry more meaning than a neutral cue (and lots more fun). For those folks with an interest in mutual dreaming, this may prove also to be a useful initiator for such a dream, coordinating the timing for lucid dream sharing.

  2. A lucid dream race: players log on and join the race, then go to sleep. The host site waits until all the respective LD local programs indicate REM state for all the players (hopefully at some point all REM’s coincide). The host site sends commands to all the local programs to cue all the dreamers more or less at the same time. The dreamers, upon becoming lucid, signal to stop the cue and, in addition, send a message to the host site that they are lucid. The winner of the race is recorded on the host site and the players can view the results–just for fun, of course, but competition can have a strong motivational effect, as many psychologists know.

  3. This multi-player scenario would require a mask with various colored lights or audio cues and dreamer feedback variability. The dreamers, upon both becoming lucid, signal different eye movements to the other dreamer (via the local LD programs’ connection to the host website) which result in varied cues, the meaning of which is agreed upon beforehand when the players register for this ‘game.’ A “hello” signal from one dreamer can result in a ‘blue’ cue to the other; an “I am flying” signal from the other dreamer could result in a ‘yellow’ cue to the first, and so on. Audio messages could be used as well.

  4. Masks or other cuing devices with multiple cuing options such as varied colors could also be used to enable more than two dreamers to send messages to the entire group in the same session. Dreamers sign up for the night’s session and assign themselves a color cue or audio cue. As the dreamers become lucid, the host software sends that dreamer’s cue sign to the rest of the group. A dreamer, for example, recognizes the ‘red’ cue as “Mike has just joined us” and the ‘blue’ cue as “Sally’s lucid now too.”

While the lucid dreamer communication described here is very rudimentary, the exciting thing is that such dream games as outlined above are technologically feasible right now. We are at the point with inter-dream communication that Alexander Bell was when he spoke “Mister Watson, come here! I need you!" And we saw where that led.
