Gadget Freak Case #256: Yoga Breathalyzer 25890

The yoga breathalyzer is a breath visualization tool to help you understand and get in touch with your breathing.

Breath is the basis of yoga and meditation, and this biofeedback tool is one way to develop a deeper understanding of your breath. Using Arduino, a headset-mounted wind sensor, and an LED strip, the device makes it simple to translate breathing into visual output.
