There are probably tons of Arc reactor props made around the web and yet here is another one. I decided to make this instructable since I managed to take photos of what I was doing. The project came about when I was asked to build something from scrap to serve as a backlighting for microscopes. I was fortunate enough to have access to a CO2 laser cutter which made the project so much easier. Anyways, I want to share how I made the light for my DIY arc reactor. So here we go.

Step 1: Creating the Backlight.

To build the backlight I just laser cut an acrylic sheet 3" in diameter and made shallow cuts on one side. I made about 100 lines towards the center. The CO2 laser I was working on was quite old already my settings for the shallow cuts made was 20% power and 50% speed. This setting made the cut deep enough for the light to refract.

Step 2: Wiring Up the LED's

Didn't have much LED's to work with. Luckily, I found sidelight LED's work best, since they are thinner. The photo above uses toplight LEDs. Simply place the LED's around the acrylic. Distribute them as evenly as possible, I was lazy and was just doing a prototype when I took the photo. I wired them up in parallel, take special notice on LED orientation when gluing them on the side of the acrylic.

Step 3: Get Something Shiny!

I laser cut a pretty simple pattern and gutted an old broken 2.5" hdd. I took out the motor and the disk. Also took the washers and a few screws. The copper wire was from an old electrical cord. Secure using instant glue or hot glue. I prefer instant glue since it dries faster.

Step 4: Cover Up the Wiring.

Using an empty kapton tape spool, I placed the assembly inside the spool and secured using hot glue. The LED's were wired without resistors and powered by 2 AA batteries.

Step 5: Place in Chest and Turn It On.

The LED was bright enough to be seen through thick fabric. Enjoy.

Well it turned out great! You should definitely enter this into the first time author challenge! Like I said top notch!
Well, rules says I'm not eligible since I'm not a resident of any of the mentioned locations. Hopefully, someone can use this. :)
<p>Wow! That really turned out great! I love the idea to use windings from the motor of an old hard drive. Top Notch!</p>
thanks for the comment :) that was my first instructable.
