NEW TUTORIAL: Metal Inlay Capacitive Touch Buttons
The MIDI sequencer project in the video above requires some previous experience with woodworking, so I am going to break down some of the more interesting portions of the project into self contained guides.
This guide will focus on creating metal inlay using a fine metal powder that you can make at home. I have used this technique for years as a way to add a decorative inlay to turnings on a lathe, but the same technique can be used to create unique capacitive touch buttons. You can make the button as simple as a drilled circle, or create very intricate designs with a laser engraver.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
