This was another midnight project. This is a quick view of the circuit board of my old Chinese usb optical mouse. As you can see, there’s a small (9mm) mouse scroll wheel rotary encoder and a single ...

Buffer boards can simplify encoder wiring where one encoder output ... Each additional foot of cable makes a control circuit that much more vulnerable to electrical noise. Machines with long ...

How does a stepper motor turn into an encoder? Well, that’s the MacGyver part. We are not big fans of the physical circuit diagrams ... was on a prototyping board. Of course, an Arduino reads ...
