Hackaday Prize Entry: Clunke Button Powers Accessibility


An AT button is a device that helps people with all kinds of physical disabilities to interact with their world. There isn’t much to them,  just a switch wired up to a 3.5mm mono plug or jack, but the switch is installed in a large button housing that’s easy to operate.

These buttons can be used with any appliance or toy that can be adapted for mono input. They’re a simple piece of technology that makes a world of difference, but for some reason, they cost around $65 each. Because of this, people make their own simple switches, but these aren’t usually sturdy or long-lasting. [Christopher] thinks they should cost way less than that and set out to make buttons for about $10 in materials. Aside from the printed files, all you really need to make a Clunke button is one Cherry MX in your favorite shade of blue, blue, or blue, and either a 3.5mm mono jack or plug, depending on preference.

[Christopher] and his team devised the Clunke Button in collaboration with the local United Cerebral Palsy chapter as part of their senior design project. When it came time to present the project, they wanted to find a way to be able to pass a Clunke button around the audience and have it do something when pressed. They made an interactive ticker by adding an ESP-01 and a battery. [Christopher] has since taken over the project and continues to improve the design as he progresses through the Prize finals. Code for the ticker is available on GitHub, and the button STL files are on Thingiverse.
