This is an homage to Iron Man’s Arc Reactor! I don’t claim that it’s 100% accurate in any way but I drew inspiration from photos found online.
For this project, you’ll need:
-an Adafruit Trinket 5v Controller
-a 24 LED Neopixel Compatible LED ring
-a single Neopixel Compatible LED (I cut mine from an existing neopixel strip)
-various short length M3 self-tapping screws (~5mm)
Remember to print with supports as necessary for the Diffuser and Center ring assembly. The outer ring needs to be glued to the diffuser once you’ve assembled everything else.
To wire the LEDs to the controller, make sure the LED ring input is wired to the 5v, gnd, and #4 pins on the Trinket. Then wire the single LED to the data, 5v, and gnd outputs of the ring.
The files are available publicly on OnShape under the name “new arc reactor” by Mike Via. Feel free to modify them as necessary…just don’t curse me for my dodgy design skills!
You’ll have to download and include the Adafruit Neopixel libraries…reference Adafruit’s website for more information. I’ve included the code I modified slightly from the included library below. I’ve uploaded code to mine that introduces a slow fade effect.
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!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
