Arduino based smart wristwatch that accepts gestures

Smart watches normally have small displays and so controlling them can be trickier than smart phones or other devices. There are also lots of situations, when you need to control the watch, but both of your hands are occupied. Darthmouth team has been looking for a solution to this problem and came out with WristWhirl smart watch prototype. They integrated smart control capability in to watch strap where they put 12 IR proximity sensors and piezo vibration sensor that would accept biomechanical gestures. The watch is equipped with 2’’ TFT display. Inside the watch an Arduino DUO is ticking. As a smart watch it can do lots of things including Google map navigation, music player where user can scroll through playlists with simple gestures. No watch would be great without… Continue reading

Posture sensor helps you sit straight

If you spend lots of time by computer, you notice how hard is to sit straight. Over time you lean down, slide under the table or find other position that seems to be comfortable. Well there are two theories of this thing – first of all naturally your body tries to find best position to prevent you from pains and fatigue. Anyway prolonged leaning may result in back or neck pain. So siting straight may prevent from those problems. Bu how to control yourself when you are focused in to your task. You can always feel how you are sitting. Coretech Robotics suggest simple project that may help to sit upright by reminding you all the time. Device consists of ultarsonic sensor HC-SR04 which measures distance from your head. It… Continue reading

Experience Yourself With The Live Musical Performance Visualization System

Do you want to turn your home into a mini concert, but you just don’t know how to do it? Then, you should pay attention on the below guide, as you’ll learn how to create a live musical performances visualization system! The main core of this project is the Piezo sensors, where it is used to connect to drumkit items to pick up drum hits. It is used to control the snare drum, kick pedal, toms, hats and others. Thus, it’s responsible to pick up vibrations and convert this information into an analogue signal, and then will send to the Arduino circuit. Furthermore, the Piezo sensors are connected to two wires, where are in turn soldered to a 3.5mm Jack and it is connected to the Arduino system via a… Continue reading
