The NeuroDreamer Sleep Mask by Cornfield Electronics is a meditation device that flashes colored lights at your eyelids and plays brainwave beats for your ears to help you fall asleep, have lucid dreams, or for meditation. We decided to open one up to see the details of its construction and figure out how it works.
The Brain Machine provides you with a fun, easy way to meditate, all the while being very photogenic! They work with lights and sounds that pulse at a 14-minute-long meditation sequence of brainwave frequencies. Your brain synchronizes to this meditation sequence, and you meditate. It's that easy! And the beautiful colors and patterns you vividly imagine along the way make it fun and enjoyable.
Add motion and direction sensing to your wearable Flora project with this high precision 3-axis Accelerometer+Compass sensor. Inside are two sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The other is a magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. By combining this data you can then orient yourself.
