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 ...

If you have thought about experimenting with a direct digital-synthesis (DDS) circuit but put it off, here's a nice surprise. You can get a capable DDS variable ...

Since then, the space of dev boards for 8-pin micros with USB has ... [Rupert] got his V-USB/ATtiny85/rotary encoder circuit working, and at the expense of a ‘mute’ control, also added an ...

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 ...

1. This optimised analogue-conditioning circuit can avoid signal distortion caused by nonlinearities, and guarantee an optimum interface between the encoder and ADC. 2. shown is a normalised RC ...
