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 ...

A new combined interface for Optocode absolute rotary encoders allows simultaneous communication of both absolute and incremental rotary position data. The interface provides cost-effective ...

POSITAL’s high-performance IXARC optical rotary encoders are now available with EtherCAT communications interfaces. EtherCAT (Ethernet for Control Automation Technology) is a special form of ...

[Blake]’s interest in building keyboards happened naturally enough — he was looking for a new project to work on and fell into the treasure chest that is the mechanical keyboard community. It sounds ...

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 ...
