Hide Capacitive Touch Buttons In Your Next 3D Print
1 min read
Summary
John Phillips, from the US, has created hidden capacitive touch buttons that can be embedded in 3D prints.
They can be used in place of physical buttons to control devices such as lights, and are simple to make, requiring only a conductive surface, like copper tape, and a microcontroller.
The process involves embedding the conductive material into the print at the desired point during 3D printing, with three layers of tape into the print for a good connection, but without interfering with the print’s ergonomics.
Once the print is finished, wires can be soldered on to the conductive material to be connected to the microcontroller.
Examples of uses for the touch buttons could include while travelling, making it more difficult for border security to tamper with luggage.
