Device to measure sports performance

This device named as Fight Coach is sensor system that can be inserted into sports gear which will permit fighters to manage evaluate their performance. By tracking the athlete’s hand movement and displaying it in real-time, Fight Coach can help athletes optimize their training. However, the main advantage of this device is that it’s small enough to fit into their equipment without causing much trouble or comfort problem to the athlete. Moreover, it has USB rechargeable battery system along with a wireless system. The ATMEGA32U4 microcontroller does the major work which is also connected to a RN-41 Bluetooth module for wireless functionality. Motion data, generated by the accelerometer and gyroscope, is obtained by the MCU via i2c, and the MCU then transmits that data to a Bluetooth module via UART,… Continue reading

Accelerometer based sport analyzer

Well this is quite big project that include several microcontrollers including Microchip 18F, Texas Instrument DSP, also an Xbee transceiver. As this is a semester project it has a very detailed description of device working and building process that include making PCBs, building case with engraving. Sport accelerometer itself is used in athletics to determine their wrong foot steps especially near finish. Transmitter with accelerometer simple reads accelerometer data and then transmits it to computer with DSP. So coach can see when athlete makes a mistake (he even gets a sound signal when he does that) and can make corrections for the next time. Anyway if you aren’t interested in sport accelerometer itself, I encourage at least reading the PCB building process as it includes an oven soldering and other… Continue reading
