So Halloween is around the corner and I was wondering if anyone here had any plans to build or "hack" Halloween decorations for the Spooky season.
Me, personally, I want to do something with a mist maker and a cauldron ... or something. I think that would be fun.
A couple of Halloweens ago I hacked this plastic skull to make it come "alive". I used a regular Arduino Uno to read WAV files from an SD card. WAV files are super easy to decode and play sound samples from, and as long as you play them back at the correct speed, which in this case was accomplished with interrupts. It was a super quick and dirty approach, but I didn't have any sound-playing module. I did have to build a small audio filter and connect it to a tiny "amp" board to drive the speaker, though.
The skull also was supposed to move the jaw while "laughing" but the tiny servo I used died once it was very securely glued in place, and I didn't have the time nor the patience to take it all apart to replace it.
Maybe I'll try to repair this skull for this Halloween too.
