Tired of the same humdrum pumpkin carving routine year after year?
Build a simple light-sensing circuit that switches an LED on when the lights go out.
Just peel and stick LEDs, sensors, and even microcontrollers, to make instant circuits.
Make a spider web shooter that’ll surely spread the creeps.
Nothing signifies a rousing shindig like the distinct sound of splattering vomit, especially when it's a Halloween party based on the infamous horror film The Exorcist!
I worked out a system that lets you control all your animated Halloween props with a single microcontroller.
Turn your computer's sound card into an oscilloscope to measure limited electrical signals, using Windows software and a simple circuit.
Chilled fog creates an appealingly eerie blanket on the ground. Most homemade fog chillers use a drink cooler and PVC tubing, but that design doesn’t keep the fog in the holding area long enough to chill it properly. Our fog chiller is very easy to build and does a great job of cooling the fog.
In this project, I show you how to make decorative tombstones from plain sheets of Styrofoam.
Halloween is a good time to invest in a new toothbrush, but before you throw out that old electric toothbrush, why not use it to give your Halloween decorations a little life by turning them into super lo-fi bristlebots?
Using an ultrasonic range sensor we can sense how far away objects are.
Make Halloween props on a table move without anything touching them.
