This fun and easy project shows you how to create a simple input device with little more than a cheap piezo sensor, an old mousepad, and an Arduino board. Using household supplies and a few passive electrical components, you can create a basic physical-computing game input device for your Arduino.
The HeliRocket is propelled by a standard model-rocket engine, but instead of the engine’s ejection charge deploying a parachute, it releases the rocket’s 3 tail fins. The fins then swing up into a helicopter blade configuration, which slows the rocket’s descent by converting much of its kinetic energy into drag and angular momentum (spin). Some […]
