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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
