My buddy Danny Bulla wanted me to make him an Iron Man Arc Reactor for a Halloween costume he was working on. Here's a few shots of the reactor in progress.
Finished product, wish I had more time!
I started out with a Forox Animation camera lens attachment, turned down a lip on the inside to allow for the VCR piece I am using as a base for the central area. It was hard to find something to use as a light diffuser, but I found some dirty old broken up half- inch plexiglass.
After cutting the rough shape out, I drilled it with a hole saw and fit it to my lathe. After turning the outside perfectly circular, I re chucked it up and turned the inside so it JUST fits the lens attachment.
Here are the inset holed for the LEDs I harvested out of a Home Depot LED table lamp.
In the lathe again! Thsi time to round off the edges, and rough up a bit with sandpaper so the LED light is diffused throughout the disc.
Wiring up the LEDs. Using the wiring diagram off Instructables.com, I have two LEDs to every 10K resistor. After I got this all wired up, I decided it was too dim, so I replaced the 10K resistors with 2.2K. Much brighter!
Central area made of motor windings and VCR parts, I'll turn the light panel for the center out of the same plexiglass.
