DivaCon2040 is a firmware for DIY Project Diva Arcade controllers based on the RP2040 microcontroller as found on the Raspberry Pi Pico. It is pretty much tailored to this specific use case, if you ...

If you’ve seen a big air-variable capacitor, you may have noticed that some of the plates may have slots cut into them. Why? [Mr Carlson] has the answer in the video below. The short answer: you can ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

Abstract: In recent years, the negative capacitance effect in ferroelectric (FE) materials has attracted significant attention from many researchers around the world. The negative capacitance effect ...

Abstract: For a capacitor with defined geometry, dimensions, and dielectric material, the capacitance normally cannot be changed. In this work, we found the apparent capacitance can be significantly ...
