Hello,<p>We want to get your opinion on a product we developed. It's called watchX. It's simply an Arduino on your wrist with lots of sensors, screen, Bluetooth, battery and charging circuit. It designed to help you develop applications that are wearable. watchX also has a watch OS which includes two games, some watch apps and beautifully animated UI.<p>Since we have a compact and lightweight design we wanted to challenge ourself to measure height of a ceiling using modern technology:) We have 3D model of watchX that includes even resistors and capacitors on the real thing. It's easy to draw a case to watch once you have the 3D model.<p>Here is the video link: https://youtu.be/bHaP2b0yczk<p>We are currently on Indiegogo receiving pre-orders for watchX: https://igg.me/at/watchx/x<p>Let us know what you think:)
