Like many people, [Mike] has a list of things he wants to do in life. One of them is “fire a gun with a switch,” and with a little help from some hacker friends, he knocked this item off last weekend.
For those wondering why the specificity of the item, the backstory will help explain. [Mike] has spinal muscular atrophy, a disease that was supposed to end his life shortly after it began. Thirty-seven years later, [Mike] is still ticking items off his list, but since he only has voluntary control of his right eyebrow, he faces challenges getting some of them done. Enter [Bill] and the crew at ATMakers. The “AT” stands for “assistive technologies,” and [Bill] took on the task of building a rig to safely fire a Glock 17 upon [Mike]’s command.
Before even beginning the project, [Bill] did his due diligence, going so far as to consult the Bureau of Alcohol, Tobacco, and Firearms (ATF) and arranging for private time at a local indoor gun range. The business end of the rig is a commercially available bench rest designed to control recoil from the pistol, which is fired by a servo connected to the trigger. The interface with [Mike]’s system is via a Raspberry Pi and a Crikit linked together by a custom PCB. A PiCam allowed [Mike] to look down the sights and fire the gun with his eyebrow. The videos below show the development process and the day at the range; to say that [Mike] was pleased is an understatement.
We’re not sure what else is on [Mike]’s list, but we see a lot of assistive tech projects around here — we even had a whole category of the 2017 Hackaday Prize devoted to them. Maybe there’s something else the Hackaday community can help him check off.
