Balancing of a Ball on Beam using Arduino as a PID controller

“I used Arduino Uno as a PID controller to balance a small ping-pong ball on a 4-bar mechanism. And used Matlab to plot the position of the ball vs time.”

Ultrasonic Distance Sensor Visualizer W/ Processing

“this project uses processing to take data from an ultrasonic rangefinder on an arduino board and input that into variables in a processing sketch.”

Spread Spectrum Phased Array Sonar

“Motivated by success on other acoustic projects and by this brain transplant blog, a sonar project sprang to mind. A phased array sonar works in the same way as a phased array radar. Rather rotating the sensor to look direction …

Ultrasonic Piano

“Note: Above is a video - it may show as a photo only on some mobile devices. This is an ideal project for a science fair etc. - it’s not too difficult to construct, yet makes a playful interactive exhibit. The …

The CNC Bubble Iris: A Computer Controlled Giant Bubble Machine

“The CNC bubble iris makes big soap bubbles in a new way, by weaving soapy strings together and apart with a motorized iris. It was designed to allow large soap bubbles to be made automatically with great repeatability, opening up …
