It’s also a very handy thing to have when paragliding, which is why [mircemk] decided to build a hand-held version using the Arduino Nano and a BMP180 pressure sensor.

The additional sensors include a nine-axis Inertial Measurement Unit, as well as temperature, pressure, humidity, light, color, and gestures sensors.

The Seattle-area startup today debuted its first-ever running shoe, which retails for $199 and features embedded textile pressure sensors designed to provide real-time biometric feedback.
