Laser Lissajous with Audio Sync
This project uses a Freeduino (Arduino clone) microcontroller, Python code, a couple of motors with attached mirrors, and a laser pointer to create patterns (Lissajous Figures) that are in sync with audio played from a computer. Objective The basic idea here is to create some laser patterns that are in sync with music (or any […]

Mini R.O.V. Submersible
This is a great, easy project! This project is also a first prize winner in the 2012 Instructables Robot Contest! This little submersible uses 3 DC motors and a nine-volt battery. It controls the three motors with three buttons. Its frame is built from lego-type pieces. It is very simple and great for beginners, although […]

Simple Van de Graaff Generator
When I was younger, I spent hours perusing Bill Beaty’s electrostatics web pages. At the time, I didn’t achieve any real successes trying to build his high-voltage contraptions, and so my interest waned. Years later, I saw someone online use a soda can as a collector for their Van de Graaff generator, and all my […]

Projects in Motion: Control Three Types of Motors with 555 Timers
With an estimated one billion 555 timers manufactured annually, you know this component must be versatile! We’re going to learn how to build and control drivers for three very different types of motors using a breadboard, resistors, diodes, transistors, and some 555 timers (along with a sprinkling of CMOS logic). These motor drivers are the […]

Infinity Light
Convert your DC motor into a dynamo and use it to generate light without batteries. All you need is some capacitors, a DC motor, diode, wire, gear system and LED. To make it light all you need to do is spin your dynamo.
