Maker Marcus Olsson has designed ED bracelets before. Marcus’ last project featured an accelerometer so that the LEDs would react to the wearer’s movement. Now, his newest iteration sports a microphone that allows the illumination to react to the sounds that surround it.
The Maker’s friends began to pester him for a creation that interacted with the soundscapes in their environment, so he quickly got to work on this device. Powered by an uber-mini Trinket MCU (ATtiny85), the bracelet allows a microphone to communicate with a Neopixel strip affixed within the casing.
After an initial test, Marcus needed to make some adjustments to the 3D-printed shell of his bracelet to better incorporate the microphone. After some slight tinkering, foam tape enabled the microphone to be secured.
