What did I do?
I developed this project from start to finish. Electrically, this circuit involves either an Arduino or my Standalone ATMega circuit taking in vibrational data from a piezoelectric element and outputing a pulse of cyan light along the LED strip. I also designed a PCB for this project so that it can be mass-manufactured easily. The casing is housed in a 3-D printed enclosure that I designed. All of this information is available in much more detail in the report I wrote about this project, available for download here.
