Mineral Element Browser (MEOWSER) is a wooden cabinet containing APEX mineral samples with LED lighting controlled from a laptop computer. The laptop can display either the periodic table or a layout of the cabinets. When the user mouses over elements or minerals the appropriate lights in the wooden cabinet light up. An Arduino microcontroller serves as the computer - LED interface.
The MEOWSER Video Introduction is posted here.
There are several more videos if you want more details.
This Blog describes each of the APEX minerals I collected. I discuss the minerals for each element and also some interesting properties of each element.
APEX Minerals in the Periodic Table is the master index page into all the challenges I had collecting APEX Minerals.
