It is understandable if you get choked up (and find your faith in humanity restored) while watching this TEDx Talk by 14 year old Jacob Smilg. In it, Jacob recounts how he used his tech know-how and love for his friend Ethan to create a device for Ethan to more easily communicate after a freak accident and resulting brain injury.
In the summer of 2013, while at summer camp, on a clear and cloudless day playing Frisbee in a field, Ethan Kadish was struck by a bolt of lightning. The jolt stopped his heart and the resulting brain injuries left him unable to function independently, making it impossible for him to speak, or even to breathe on his own.
When Jacob learned that Ethan did retain the ability to blink his eyes to answer yes and no questions, he had an “ah-ha” moment. Using a microcontroller in a 3D printed case, an LED display, and two big buttons mounted onto Ethan’s wheelchair headrest, Jacob created a simple Yes/No device that Ethan can use instead of blinking his eyes. This makes communication less ambiguous and allows him to communicate with more people. “With my device, Ethan can more easily communicate with a group and having real conversations makes him overjoyed,” says Jacob.
