Marcus Olsson loves to hack and he’s been creating a series of LED bracelets that we have been following. His first one was motion activated, but his latest version is a VU meter. That means it is party ready! You can make one, too, because he has posted his work and code here on Slickstreamer.
The 3D printed bracelet uses a Trinket, mic, power switch and Neopixel strip. After gluing things in place, he added a bit of foam to keep the mic protected. It’s a tight squeeze, but Marcus made sure to enlarge the 3D print design to account for the mic addition. One of my favorite parts of the build is his use of small magnets to snap the cover in place.
He’s done another great job and he even has another use for the bracelet — a camping or beach lamp! Now he just has to add a citronella dispenser and he’ll be able to repel bugs.
The code Marcus hacked was mainly from our Ampli-Tie Learning Guide. So, why not follow in his footsteps and learn about NeoPixels and mics. You’ll have something special whether you’re seen clubbing or camping.
