MSRD exposed wiring and circuitry. MSRD battery container and power switch. All components soldered onto mini breadboards. (Top) Amplification and filtering circuits. (Bottom left) Motor control circuitry. (Bottom right) Arduino Nano board. Complete motor control circuitry. Each of the four vibrational motors can be independently controlled by the Arduino.EMG amplification and filtering circuitry. Four independent EMG signals can be amplified (1000x gain) and filtered (10Hz – 500Hz bandpass) before heading to the Arduino. Extended belt. A weightlifting belt was extended to fit a larger range of waist sizes.
