What is it?

A rechargeable glowing wristband that reacts to music, powered by a thin LiPo battery. The TPU band has 15 LEDs inside. The animations are driven by audio analysis and controlled with a ATtiny processor.

Why did you make it?

I like electronic music events and festivals and my wife likes to dress up so I wanted to bing this together. I enjoy the synesthetic aspect of sound and light in a good club and so am I always trying to make the lights dance.

Technical details

Charging the wearable takes less than 20 minutes. The two LEDs on the side of the plug will provide charging progress during charging. The wearable has a BMS directly at the battery to prevent over/under charging. I run the LEDs and processor directly from the battery. The built-in charge-controller will manage the optimal charging voltage. A Full charge is good for about 5 hours. The wristband is NOT water resistant

The colors of the lights can be changed with the push button on the side. Click for color change:

• Yellow
• Green
• Cyan
• Blue
• Purple
• Pink
• Red
• White
• RGB multicolor

The RGB multicolor mode has 8 color pallets. They will be combined with 9 animation algorithms, this results in 8*9 = 72 different impressions of the animations. All animation algorithms react to beat and sound volume and will automatically adjust the gain at the festival or club - it works best when its loud.
