This Gesture Sensor Is Precise, Cheap, Well-Hidden
1 min read
Summary
In a recent Hackaday project, developer [RealCorebb] added gesture sensing to a desktop clock without using a typical optical sensor and opted instead for Microchip’s MGC3130 chip, which works via “E-field” sensing.
This type of sensor is more precise than regular sensors and can work even inside a case or enclosure, but it does require a larger PCB, roughly the size of a laptop touchpad.
The project is well documented and includes a YouTube demo, along with a GitHub repository containing the necessary PCB design, bill of materials, schematic, and software tools.
The developer also provides explanations, Arduino examples, and Python scripts to help others recreate the build.
This increasing interest in touch and gesture-sensitive projects has been covered recently by Hackaday, which showcased an open-source 3D-printed trackpad.
The source code for this project is available on GitHub.
