So if I remember correctly, after all these years, the story goes like this. One night when I was a Junior in high school, I had a lot on my mind and I couldn’t sleep, so I pulled an all-nighter and made myself a pair of light-up cat ears. Then I posted about it to Instagram.
I did put the parts list on my Instagram, but never got around to making the Instructable.
Cat Ears V1.0 was my absolute favorite accessory as a teenager! I would wear the headband everywhere - to school, to the supermarket, on the bus, on dates, literally everywhere. Especially on days when I needed extra confidence (such as for a Calculus quiz), or for parties/holidays like Mardi Gras. I even wore them some days when I was up at the front of the room teaching the CodeKCS class in Senior Year.

I was sixteen years old when I made these ears. I was - and still am - absolutely obsessed with cats.
The cat shown in the video was our beloved cat Rumba.
Rumba, you are so very loved and so very missed. 
You were the light in my life amid so much darkness, and the reason why I am still here today.
