As wonderful as mechanical keyboards are, most of the pre-fab and group buy models out there have zero media controls. If you want rotary encoders and OLED screens to show what function layer you’re ...

Integrating touchscreen and rotary-knob control into a single IC simplifies combining these two different but complementary user-input devices. Touchscreens and touchpads haven’t totally taken over ...

The electric motor is the fundamental building block of almost all robotic projects but, without some form of feedback, it lacks the precise positional control required for the task. Small servos from ...

After spending quite a bit of time with it, I think it’s finally a good time to share some thoughts on the Gamo2 Faucetwo ...

Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots ...

Rotary encoders convert rotary movement or angular position into analogue or digital signals for use in measurement or control systems. They can be classified in a number of ways, primarily by the ...
