Uranium Marbles Display

Uranium marbles display

About a decade ago I recieved some uranium doped glass marbles from United Nuclear, and I finally got around to making a display for them as pictured above.

The case was designed in OpenSCAD 3d printed by Shapeways. Inside there are six 395nm UV LEDs, each independently controlled by an Adafruit ItsyBitsy. I filled it with lead shot and epoxy to add enough mass so a twist the cable won’t flip it over.
