After numerous requests, we are offering a lasercut acrylic from the Adafruit Superhero Power Plant (Arc Reactor) tutorial. If you don’t have access to a laser, or would rather focus on the assembly/programming, this is just the plastic part.
This is an open-source design, you are compensating for the materials and labor.
This contains 3 pieces of acrylic cut according to the part on Thingiverse. Plus a piece of plain white paper also cut to the same size. (we felt the light diffused better when a piece of paper was inserted).
The tutorial can be found here:
This is for the default size, which is approx 2.5″ (6cm) in diameter. It is somewhat smaller than the movie-style Arc Reactor, because it was designed for the original (approx. 2.5″/6cm) NeoPixel ring. By request we also offer a 3.5″ scaled version of this.
Here is a link to the tutorial. http://learn.adafruit.com/superhero-power-plant The detailed instructions can be found there.
If you want to make it, here are the other parts you will need:
Medium-sized Neopixel ring
Single Neopixel (or get 4, they’re small)
We adapted it for a Coin Cell Battery plus Sewable holder (to avoid using a lithium battery charger). We used this holder because it’s flat.
Switch for battery
Miscellaneous Wire and Solder (we personally like the Adafruit-curated wire kit, and here is some ROHS solder)
Soldering Iron (if you are looking for one, this is a reasonable starter soldering station)
Coil-wrapping wire (we used either wire scavenged from discarded induction coils, or Radio Shack coil-wrapping wire, to get that coppery look)
A piece of plain printer paper (preferably cut to fit, this product includes one)
Black dry-erase marker
Good luck and if you have any questions the internets can’t answer, email us!
