Introduction: Hey there! Today, I'm excited to share my experience with you as I delve into the world of pen plotting. I have always wanted to try one of these! I will tell you right now that I am a complete novice. I have only seen these in videos and...
OVERVIEW Smartphones are becoming a staple piece of technology for many citizens in North America and around the World. Smartphones and touchscreen devices enable users to navigate around their city better, to communicate with others more freely, and...
A pendulum clock is conceptually very simple. A spring or falling weight provides energy to a swinging pendulum that swings at a constant rate. A series of gears convert the pendulum motion into a display for the hours and minutes. ...
I've come into a few stepper motors, and have been scratching my head about how to connect something to them. You can buy pulleys, but you'll pay good money for any kind of metal collets. I hate paying more for a collet than just buying a new...
