We looked for tiny, autonomous, easy to use, and 9 Degrees of Freedom IMU, but none of the available wireless motion sensors were affordable enough to really unlock creativity, so we built one.
In a few simple points, here are the specs:
– 9 DoF with on-board sensor fusion (more explanation below)
– Easy to connect with BLE: good for computer + smartphone + tablet connection possible (lower power than WiFi)
– Compact & autonomous: Embeds a CR2032 battery holder (available in any corner shops, gas stations…)
– Size of a coin cell battery!
Here is an arty example by one of our early adopters:
HOW TO USE IT ?
Twiz modules are the most universal tools for wearable technologies, applications are simply endless but here are a few examples :
- Media control: modulate sound effects or control a light show from performers’ motion
- Scientific studies: analyse a building/bridge vibrations, animal activities…
- 2/3D Software: motion capture to animate 3D model of object, human or virtual creature
- Games: control your favorite doom-like from your hand, or breakout
- Anything that a beacon or activity tracker does
- Home automation: control your room’s light volume by spinning your candle:
MPU9150, 9 axis IMU motion sensor:
3D accelerometer for linear accelerations, 3D gyroscope for rotational accelerations, 3D magnetometer for orientation reference
nRF51822, processor + connectivity:
32 bit ARM processor with low consumption optimization (Cortex-M0), BLE (Bluetooth Low Energy AKA Bluetooth smart/4.0)
Physical characteristics :
2.4 cm x 2.4 cm (< 1 inch), 1.1cm thick (< ½ inch), 4.6g (~7.6g w/ battery)
It started with usual dev boards such as teensy, IMU and radio modules:
