Happy Halloween!
Halloween is made for makers. Whether your thing is an over-the-top, automated yard display, an amazing cosplay costume, or a beautifully carved pumpkin with an RGB LED light show emanating from it, this holiday lets us build things not because they're practical or necessary, but because they are fun!
As a young kid, my parents saved up a small fortune and took me and my siblings to Disney World. While I knew that it was magical, I also understood that it wasn't actually magic. It was all some kind of clever engineering, created by incredibly smart people. The thing that stuck with me was was the fact that the birds in the Tiki Room, the country bears in their jamboree, and the presidents in the great hall all had their mouth movements synced with their respective recordings.
Fast forward to last week, when I was asked, "Do you think you can come up with a blog post for next Wednesday? Oh, that's Halloween, so maybe something Halloween-themed." I had a bag of plastic skulls and a box of googly eyes in my drawer (pro tip: Always have googly eyes on hand. They make every project better). So with the help of a Teensy 3.6 and the Teensy Audio Shield, I threw this together.
The LEDs on the circuit board were for testing so that I wasn't sending out the continuous clacking of the solenoids the entire time, because apparently that sounds like popcorn, and then people come over expecting delicious popcorn and are very disappointed (sorry, Jeff).
I had originally started this idea to make singing nutcrackers for Christmas. If there's any interest, I may do a future post to break it down and share the entire process, code, etc. Until then, happy Halloween, and happy hacking!
