I just found a website that will make you them for $60 and on dreamviews they have there own version called the kvasar.
would you like to share the link to this site?

Hey Guys
I am from the United Kingdom
I decided i am just going to go out and build a simple timed lucid dreaming sleep mask,
It would consist of a 8 feet long sing cable which one end is a power plug which will connect to a digital timer and the other end will split into 2 heads which will have red blinking led’s soldered to them and then they will be placed inside a foam padded sleep mask and that’s it.
So i got some questions:
I have already got a digital timer but they only switch off and on a device within minute intervals. I want something that can do it in the seconds, so for instance it’s 02:15:05 the light comes on and then at 02:15:10 it goes off after 5 seconds. So anyone know of a good digital timer that does what i describe and allows many times to come on and off throughout the night, like at least 10 times per night?
Also does anyone know of a electrician shop where i can go to and just get the device built, you see electrician shops have already all the components which are very simple, i would supply the digital timer, but they could build something like this within 5 minutes, they only need to solder a few points and get paid. I could do it my self but would rather pay for it to get done. Do you guys know anyone in the United Kingdom that can do this?
Please any help much appreciated
Many thanks
Hey, I’m new here and thought this was a great site so I just joined up. I’m currently researching on how to make a mask similiar to the NovaDreamer, and what it takes to do this. Searching I found that someone has already done this, it’s called the Kvasar. But I don’t how credible this is, or if it even works. 
I’m wondering has anyone had any experience at all with the “Kvasar” dream mask? Has anyone built this, or given this a shot?
Here is a link just in case for those that haven’t seen this:
brindefalk.solarbotics.net/kvasar/kvasar.html
I’ve heard of these masks. They start vibrating or sending you other signals while you are on the REM stage of sleep, to help you recognize it’s a dream and increasing your awarness. (At least some masks.)
I haven’t built this mask since I’m no electrician expert. But I would definetly want to try one. 
ok, a few different things. 1. we have a thread specifically for this topic(making your own dream mask) so mods, please move this. 2. I am an electronics person and the kvasar is a hard project…esp for a newbie to it. the sensors are hard to come by(when I was trying it I had to call the company and request a sample). I had no success with getting the mask to work and I have yet to hear anyone having success building it besides the author.
But if you find anything cool in your research on dream masks, feel free to post it in the main thread. Also, feel free to pm me about it anytime, I find this area quite interesting.
2. I am an electronics person and the kvasar is a hard project.
I have built the Kvasar and I will verify that it works fine, but no LD’s yet. No offense intended, rarebreed, but if you are an electronics guy, you must not be very good at it. It is an easy project - even for a beginner!. I created a PC board in Cadsoft Eagle. I can post my files if anyone is interested.
The sensors are hard to come by(when I was trying it I had to call the company and request a sample.)
I used one of the alternate sensors posed on the website (Sharp IS489). it is available at Digi-Key for about $1.00. You can also use the Honeywell sensor - also available at Digi-Key for about $1.50 The original sensor is made by Hammamatsu. Hammamatsu don’t sell through distributors and their minimum order is 50 pieces.
BTW, the website for the Kvasar seems to be dead.
A few things, 1. I suppose you are right about the Kvasar…I kinda tried it before I even knew much about electronics, and the main part that is “very hard” was the sensor for me, getting it was a pain(I got the original) and they weren’t very easy to work with/accurate.
I suppose I said I hard time with it just because I never got it to work before I scrapped it. That and a lot of people on here seem to get scared as soon as they see they need to program a pic.
Ok, enough with the defensive, I know you meant no harm…just wanted to say that although I still am an amateur, I am quite good at it. Its my future major in college and future job. But yea, thanks for the info on the site in case anyone(myself included) wants to have a go at the kvasar, and yes, the site does seem to be dead. I wonder if there is a backup somewhere…
I would be interested in talking some more with you though, as Im always interested in talking to other tech people with interests in fields such as lucid dreaming. extends peace offering Im going to send you a pm to keep any chat-talk off the board.
Yes, I was a bit harsh and I apologize. Its just that I have heard so many negatives about the Kvasar - “The sensor is hard to find” - “uncomfortable”, etc. all problems that can be fixed if you read the directions and the manual very carefully.
Thank you, and if we ever find a backup of the manual for it; maybe you could put up a footprint of your LEDs/sensor positioning.
where did you guys get the main chip?
I am pretty sure you need a programmer of some sort can someone explain?
Hey Mods, shall I start a new thread for the kvasar (the other is quite dated), post here, or use the old thread? (The Kvasar is “building your own LD goggles”)
This may get moved but I will post anyway. To all of those interested, I have The schematic, manual, and both versions of the firmware for the Kvasar. I have also designed a .sch and .brd files in Cadsoft Eagle if anybody wants to etch a pc board. I will post the files if anybody is interested. Let me know. Or if the mods would be happier, you can pm me if you want the files.
I used the Sharp IS489 for the sensor. It can be obtained through Digi-Key for about $1.00. I was also considering designing a “discrete” version of the sensor. I could add an op-amp, and a Schmidt trigger to the board. Then just mount the photodiode in the goggles and PRESTO - instant sensor.
The sensor should be arranged in a semicircle about 1 inch diameter. The sensor on the top, the IRLED on the bottom, and the visible LED on the outside. (quite tricky!)
Also adjusting the IRLED brightness is tricky. Too bright and it can’t detect the changes - too dim and it can’t detect at all. There is a window in between where it works perfectly. You can use a remote to test it. You also must calibrate it before each use.
Those of you who don’t know how to program a PIC may have a hard time with the Kvasar. There are freeware programmers all over the Internet, but they do require at least a basic knowledge of electronics to build.
I will help anybody to the best of my ability who wants to build the Kvasar. I think it has great potential. Especially for those who can’t afford to spend $500 for a professionally built model (the Kvasar costs about $20 to build).
Good luck to all LDers. I am still looking for my first.
OAR Raider,
The main chip used in Nate’s design is a PIC16LF628A. The main chip used in the Kvasar is a PIC16F84A. The two chips have identical pinouts and could be interchanged for many applications. The 628A is a much better chip and it costs about half as much money. There are 4MHz and 20MHz versions of both chips. The 20MHz chips are not necessary for any projects mentioned in this thread, so buy the 4MHz version. They are much less expensive.
Both chips can be purchased through Digi-Key, Mouser, etc. for just a few dollars. Check the Microchip website for datasheets. If you are a student or a business you can get free samples.
Regards.
Hey computerman, Thanks for all the info! Im still quite wrapped up in a different project, but if I ever come back to the kvasar all your info will deffinitely help. One little idea though, at the beggining startup of the kvasar, couldnt you have the chip slowly modify th irled brightness through pwm? Make it so you put the mask on, turn it on, then move your eyes back and forth until it beeps or blinks saying it has auto calibrated. Just an idea.
P.S. about my other project, do you have much experience with serial lcds? Mine used to work fine and is now having problems. Im having a really hard time debugging it too, cant figure out what is wrong with it.
That is kinda how it calibrates. To calibrate, you put the goggles on and push button B. You will hear one beep and the left LED will light. Do that with your eyes open. Then you close your eyes and push button A. The left LED will go out and calibration will start. Shortly after you will hear 2 beeps. Then push button C. DONE. The whole calibration process takes about 10 seconds.
I may have found another alternate sensor as well. I will test it and let you know what results I get. Cross your fingers!!
As for serial LCD’s, I have not worked too much with LCD’s and what work I have done they are all 4-bit parallel - But we are getting off-topic. If you want to discuss your project more, please PM me.
Just letting everybody know that the Kvasar website is back online - for how long who knows. I have created an archive of it just in case it goes down again.
Ok, sounds like a pretty good way to calibrate the device and good luck with the sensor. Yea, I will keep my project off this thread, just wanted to ask that real quick since I was at a dead end. Also thanks for creating an archive, its always a pain when something good seems to vanish from the web. Maybe you could put up a link to that archive/all the different files for it you have accumulated(modified source code, pcb, etc.)
I have a zip file with all of my accumulated info about the Kvasar, but I don’t know how to post it? Anybody?
Hmm, this sounds interesting, I’ll have to try making one for myself.
Hi to all!
Im from Hungary, I dont speak englis too good so I somethime write wrong.
Plese anybody say to me: The Kvasar is work good?
I has made 1 of this… but not work. I think ther is a problem whit transistors because i tur on the machine and all LED-s are lighting and the speaker try to beep.
I use the HLC2701 sensor. I programed the PIC whith the moded program.
(Sorry for the errors!)
Thanks very much the reply!
