You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed ...

[Jesse Merritt] bought a manual speed controller for his router. It’s used in the CNC mill he build and he figured, why not add the ability for the computer to control the speed. The speed controller ...

This could be an interesting one if you work with robotics, flagged by the Arduino team - a look at how to smooth the operation of a servo, to avoid jerking between positions. It's from the YouTuber ...

The project illustrates a wireless webcam that can be moved around on a pan while providing tilt mechanism and be able to control it over the Internet. The project illustrates a wireless webcam that ...

Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on a ...

These little Arduino boards are a real boon to amateur electronics tinkerers: cheap, versatile, and very small. This guy had the idea to make a high-speed photography setup using one, instead of the ...
