One thing I miss from my old stereo system is the big volume knob, maybe you wish your computer or laptop had a volume knob too, too? This tutorial will show how you can build a little desktop toy that lets you quickly set the volume without having to open up iTunes or your control panel or run amixer If you have a rotary encoder with a built-in switch, you can even extend this project to turn it into a volume/mute control
Wear some space on your face and be a constellation for Halloween! This galaxy makeup is inspired by the Cassiopeia constellation and uses five FLORA NeoPixels to light up the night sky across your forehead, affixed with liquid latex.

Here is a quick project for an electronic Halloween pumpkin. With a bit of hacking a $1 plastic pumpkin is upgraded: a sensor embedded in the nose detects when people get close and will play scary sounds and animates LEDs on the face. The sounds are stored on an SD card so its easy to change and customize what the pumpkin says, while the code is written for an Arduino so it's easy to modify the behavior. I'm going to have this pumpkin outside my door to freak out the little kids who go to daycare nearby. Boo!
