Iron Man Arc Reactor Mk 1

Made by CalwinAng / 3D Printing / Displays

About the project

DIY IRON ARC REACTOR MK1. It has 2 modes, there is lightshow and manual colour selection using a button selector. It also have a special dimmable LED background lighting and a LED screen to display Tony Starks famous last phrase "LOVE YOU 3000".

Story

I am big fan of iron man. I was given a theme" Guardian Angel"for a school project. I immediately thought of how Iron Man sacrificed himself to save the universe. Hence he is a Guardian Angel to me. Here's a video to show you the lightshow. PS: Dont mind the other items on the background as the remaining space is used for my gundams.

Sorry for the blur image but I think the important parts are still visible.

                          // transition the button press logic will execute.
