Check out how I made a ring light for a GoPro with a Neopixel ring, a Pro Trinket and a 3d printed diffusion ring!

The NeoPixel ring (12) fits perfectly around the lens of the GoPro.
I’m driving it with an Arduino compatible Pro Trinket, from Adafruit.
I’m using a 100k potentiometer for changing the brightness.
The whole thing is powered with a cheap battery cell via USB…
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
