Maker collective Hackerloop modified a Nerf gun into a bionic prosthetic for their friend Nicolas Huchet. He fires the gun via EMG (electromyography) sensors that detect when he tenses his forearm muscles.
"It all started with jokes about the fact that it was too easy for us to win over him in a nerf battle, as he's missing his right hand," writes "tinkerer in chief" Valentin Squirelo.
From Medium:
DIY hardware is not just about temperature sensors and automated door locks anymore. Every hardware component used to make this gun can be found online.
"Electromyography is a great way to make the body communicate with hardware. We used it to detect electrical impulses and translated them into instructions for our gun. You could think of a thousand other uses.
You could think it's not the first problem to solve for people with disabilities, but in fact being able to have fun with your friends with these wonderful toys is also a real game changer".
