Lucid dreaming with the Circuit Playground Express #WearableWednesday

This project was sent to us by Ben J. The full project and story behind it is available on their site.

Thank you, Ben!

The basic principle of these devices was to detect eye movement using IR and then cueing the user with a colour LED that would flash at set intervals, these flashes would be visible to a wearer within a dream state. This biofeedback mechanism had been proven to work with DreamLight and I’d argue that these masks, despite being nearly 30 years old, have never really been improved upon. There have been products that detect REM using brainwaves and there’s been some interesting studies recently that will no doubt lead to more of these – however to cue a user in a dream state, the best we’ve got in terms of biofeedback is still signalling via light, so I feel eye movement detection is still a more efficient and cost-effective approach given that you’ll still need some kind of hardware over the eye.

Flora breadboard is Every Wednesday is Wearable Wednesday here at Adafruit! We’re bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA. Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
