The pictures are of a prototype, so there's components soldered around. The new boards are already updated to include those components. This is the enclosure of my latest project, a visual equalizer that uses an 8x8 neopixel grid to display 7 audio bands (using the MSGEQ7 chip from sparkfun) while the last column is used to display the battery level. Inside is an arduino with a custom shield, powered by a 18650 battery, with charge and converter board. Using the buttons on the side it is capable of:

• setting thebrightness of the display
• setting the sensitivity of the chip
• setting the orientation of the display
• writing phrases using the phrase composer menu
• setting the direction of the rainbow effect
• setting the speed of the rainbow effect

Will probably get future code updates to implement more functions.
