Design
My main goal when designing this was to easily be able to swap out the rechargeable batteries. I decided to leave one wood panel easy to remove, and do the hard wiring on the other side. The on/off switch is glued on the right side, with fairly short wires running between it and the Arduino Uno. The wooden panel on the right is also glued in tightly.
​
I used hot glue to attach the LED strip to the acrylic piece - it barely worked, but with enough hot glue it stayed.
​
If I made this again I would use extruded acrylic so that the etching is nice and frosted instead of clear-ish like this piece. I would also use screws instead of glue, so that I could easily access the Arduino to reprogram it.
