Not too long ago, a Kickstarter for lucid dreaming goggles started getting passed around the Internet. At $80 a pair, though, they’re a little bit expensive, so why not make your own lucid dreaming goggles on the cheap? It’s not very hard, as it turns out. Pretty much all you need to do is hook some LEDs to a pair of goggles, but I’m getting ahead of myself here.
For anyone not aware, lucid dreaming is the practice of controlling your dreams by being aware that you are dreaming while you are dreaming [editor's note]. Lucid dreaming goggles are a tool to help with that “being aware” part. The idea is that the flashing light from the goggles won’t wake you up, but will permeate your dream such that Dream You can figure out what’s going on and fly around, or summon an army of velociraptors or whatever.
These goggles in particular are pretty straightforward. The circuit utilizes an ATtiny85 controller so that 2 hours after the device is turned on, the LEDs will start blinking, subtly alerting the dreamer of his dream. Of course, one doesn’t need lucid dreaming goggles to dream. The real DIY solution is to make a habit out of performing reality checks like attempting to put your finger through your hand, or attempting to read text, look away, and read it again. Neither of these things work very well in dreams, so if you can get your dream self to try them and they don’t work, you can get a tip-off. That said, goggles sure do require a lot less self-discipline and training. Which one of those tactics is the easy way out all depends on your proficiency with building things. As for me? I’d only be able to put together a functioning circuit in my dreams.
