Materials needed for this project:
1/8th Acrylic sheet in pale blue and dark blue transparent (sourced from Tap Plastics
Rustoleum Hammered-Finish metallic
A cheap USB cable to hack up (I got one for a buck at Urban Ore)
Super-bright LED (I chose to go a bit more elaborate with the lighting circuit, as will be described later in the Instructable).
Basic electronics tools (soldering iron, needle nose pliers, etc.)
Bondo Spot Putty (or similar)
Acrylic Cement (I got a tube from Tap Plastics)A laser engraver
There is an existing kit (for technical reasons I can not supply a direct link, but a search for "Jedi Holocron" should pull it up); this kit has pre-cut acrylic pieces and all you need to supply is paint, glue, and the electronics.
I modified my kit extensively, to the point where I was practically lasering my own. Which is more fun to do anyhow so that is what this Instructable features.
