Channel your inner superhero with The Dazzler bracelet

Maker Michael Barretta was searching for the perfect gift for his girlfriend’s birthday. After some deep thought, he decided to develop a project based on her favorite superhero: The Dazzler. So what happens when the superpowers of the X-Men join forces with the low power of today’s microcontrollers? This DIY Dazzler bracelet.


To best personify the bright lights of the Dazzler’s powers, Barretta worked to incorporate light organs into a wearable bracelet. MAKE Magazine best describes light organs as a simple technology that causes light to pulse in tune with the frequency and intensity of sound.

Much like Marcus Olsson’s Trinket design we featured a few weeks back, this bracelet pulses in reaction to the sound around it. Undoubtedly, these wearables would be a massive hit at any party… or Comic-Con, of course!


Barretta linked an Adafruit GEMMA platform (ATtiny85), a microphone breakout board, NeoPixel RGB LED strips and LiPo battery to establish the dazzling effect. The microphone adapts surrounding music into a sequence of LED flashes. For even further customization and personalization, the Maker 3D printed the bracelet enclosure to perfectly fit his girlfriend’s wrist. The schematics for the bracelet itself can be found here.
