Would you people be interested in a light device that might help with your insomnia? 'cause I'm going to try to make one and I could use some help. I only said might because the scientific evidence so far is inconclusive.

As you probably know, bright light treatment helps with insomnia too. Here's a good article about a study.

The obvious problem with the setup here is that you're forced to use the light for 3-4 hours at a time (It was, I think, just ambient light). There are probably fairly strict limitations to how far you can stay from the light making it less than convenient long-term.

These guys have solved the problem by using extraocular light - lighting the back of the knee instead of the eye. That would place relatively little restrictions on movement. If it works, that is. Some studies haven't been able to replicate their results.

I will try to find a pad of sorts I could stuck to my knee and plant 480 nm blue LEDs (these work best) to it.
