hadokenIMU is an Arduino Leonardo compatible 9DoF inertial measurement unit (IMU) with integrated LiPo battery charger and XBee-style radio connector. It measures 1.15" x 1.75", just smaller than a 1000mAh LiPo battery.
The IMU uses a MPU-9150 chip for 3-axis accelerometer, gyroscope, and magnetometer data over I2C. This is compatible with the I2C Device Library by Jeff Rowberg (using the MotionApps 4.1 DMP implementation for the MPU-6050), and the MPU9150Lib by Pansenti.
Purchase of a hadokenIMU includes a pre-assembled IMU board without battery or radio. The ATMega32U4 will have the Arduino Leonardo firmware pre-flashed. The final board, unlike the prototype in the photos, will have black solder mask and rounded corners.
The hadokenIMU runs an ATMega32U4 at 3.3V/16MHz. This is technically overclocking, but has not caused any issues in practice, either with this or other designs. The microcontroller can be flashed via an ICSP port on the back of the board using pogo pins in the standard 2x3 header, 0.1" spacing.
Battery power is provided through a 2-pin JST header, standard on many LiPo batteries. A mini USB jack provides power to charge the battery and can be used to reprogram the ATMega32U4 chip - I went with mini USB instead of micro due to the number of boards I've ripped the mini jack off of by accident. These USB jacks are solid. The board has a 500mA resettable fuse for additional protection of your computer's USB port.
There is a header for connecting a push button (I/O pin + ground), in case you want the radio to only send data at certain times.
The product is called hadokenIMU because these boards are an integrated design for gesture recognition gloves for Super Street Fire: live action Street Fighter 2 in a ring of fire. Wear two gloves, do the iconic move, receive fire - that's what this hardware was originally made for.
Another application for the hadokenIMU currently in development is a set of poi that stream positional data for integration with visual projections.
This Tindie fundraiser also helps support the Super Street Fire project, by allowing us to build at least five pairs of motion sensing gloves for the project at a higher-quantity price.
