You might remember the first version of the Electric Mountainboard that Andres Guzman-Ballen had made. Well he just send in a tip about his second version which is very cool. Watch the video above and see some of the details below. Even though it is a single prototype Andres has gone to great lengths to make it very safe, there is a push button on the device that will kill the system if it is not pressed as all times, there is also a safety feature that will shut down the system if communication from the glove to board controller is lost.
“I just used a SparkFun flex sensor (http://www.sparkfun.com/products/8606) to control the board’s speed. The op-amp (http://www.sparkfun.com/products/9456) is used to control the constant change in current, and the microcontroller is what converts the analog signal to a digital one. The data is sent through an NRF2401 Transceiver (http://www.sparkfun.com/products/152) and the microcontroller on my board converts the data to a PWM signal and sends it to the motor controller to change the RPM. I have a killswitch located near the thumb on the glove to make the board fail-safe. The board also uses a semaphore to make sure that an interrupt in wireless communication won’t end up costing me my life.”
