Clunke is a low cost button that can be used for toy adapting and similar functions, while also providing a clean and durable design.
AT buttons are a way for someone with a limited range of motion to control his or her environment at the same level as anyone else. These buttons can be used to adapt toys and home appliances such that they can be actuated with ease. Most AT buttons available are quite expensive, and are engineered to be used in high reliability situations. As a result there are home DIY projects to make cheaper buttons, but they often lack long term suitability and are thus more stop-gaps than replacements.
AT buttons are pricey. This project focuses on low cost, with a material price point of $10, while striving to provide a durable button that's fit for daily use.
This button's initial model was created as part of a team-based senior design course. We worked with a local organization, UCP and TASC of Huntsville, to design and construct an AT keyboard and AT button.
The senior design class ended with a second button design made, but not user tested. I now maintain the project and am working toward a third design revision and user testing.
The current button design requires a hobby level 3D printer and mechanical keyboard switches. See instructions below for build details.
