Some features: USB rechargeable! Battery lasts ~5 hours on full brightness! (Perfect for DJ use), can be controlled via http through your phone or web browser over WiFi via the ESP8266! 16 super bright Neopixel LEDs, RGB colors supported, along with animations (it's bright enough to light up an entire bedroom at night), and has rare earth magnets in the base which can attach the light to any metal surface
The Web app has basic functions and supports mulitple connections. Just finished the android app with basic functionality, I will be adding a custom color picker and brightness and strobe options soon.
Parts cost was $35.. I will be releasing a how to build and the 3D files sometime soon.
Gonna make a bigger version also, 47 LEDs..
