You can use any one you like, so long as the IR diode can handle 33mA.
I used an SEP8736 for the diode
and SDP8436 for the tranny.
When mounting, glue a little barrier between them so that the only light reaching the detector (tranny) will be that reflected from the eye.
I’m running it on a 166mhz Pentium, using DOS. It works fine under Windows 98, but will not run under any OS/2 based operaing system such as Windows NT, 2000, or XP. This is why I’d like to see someone make a version that runs under Windows XP. Also, if someone with hardware knowledge converted it to USB, that would be great as well.
I used all the parts listed in the file. The optec sensor cost me $4 from Electronics Expediters (sp?) although they generally don’t sell to individuals.
In my GCSE Tech class, we have to make an electronic product for our main project. I first started making a musical keyboard, but after a while I got bored and rediscovered LDs. Anyway, I asked my teacher if I could change my project idea to one of these goggles, and he refused despite all my efforts. He didn’t mind me changing the project, he just thought the whole idea of lucid dreaming sounded dodgy (he’s never heard of it before you see).
He said “First I’ll need a letter of confirmation from your parents, or doctor, or psychiatrist or whatever” lol. “If you were my son, I wouldn’t let you.” I’m not sure if he thought lucid dreaming was dodgy, but more of the way I wanted to make the goggles. He said all different possibilities, such as “What if you wake up blind from the light?” and “What if it makes you go insane, and people say ‘He used to be such a nice boy until the Tech teacher let him make those goggles’” and he eventually refused altogether. 
He’s not a bad, paranoid teacher- just careful. If he knew what lucid dreaming was about, THEN he might have let me.
Off Topic: Come to think of it, are there any bad effects from lucid dreaming?
LAJ: There are only positive effects of LDing, as far as I know. The only problem is if you have a disease which makes it hard for you to differ fantasy from reality, but most people don’t have.
LAJ, if the LEDs were too bright, they could blind you, or wake you up (repeated awakenings CAN drive a person insane, by the way.) That’s why there is a potentiometer to set the luminocity of the LEDs.
The only other down side to lucidity I can think of was when I was told by an experienced LDer, that lucid sleep isn’t as effective as normal sleep, but that a couple of hours extra sleep would make up for this.
Could this circuit be made with a basic egg-time circuit, which starts the LED flashing after a couple of hours from activation?

This may be true for some people, but it’s certainly not the experience I’ve had.
Many people have talked about this in the past on newsgroups, etc. The problem is that there is no way for a timer to know if you’re in REM sleep or not. You only have dreams in REM sleep, so flashing lights during other phases of sleep may just wake you up – not a good thing.
Somone could really clean up selling a cheap alternative to the novadreamer!
Yeah, but they’d have to mass produce it to get a really low price. If there was a competitor, so long as they don’t get sued, then prices might be more competitive.
i just went 
when i saw this topic, because i was recently considering buying a nova dreamer and then i discovered the price! 
if anyone ever decides to start producing these… even if its just a few… email me! i would love one! steve_v_m@hotmail.com
where can I see one of these novadreamers, is there any website that has them with prices and stuff?
if not, how much do they cost(in australian dollars if possible)
