As you may have noticed, I’ve been working with an STM32 ARM CPU using Mbed. There was a time when Mbed was pretty simple, but a lot has changed since it has morphed into Mbed OS. Unfortunately, that ...

There are plenty of radios you can buy that pick up MW and SW bands if that’s what you’re into. Or, you can follow [mircemk]’s example, and whip one up yourself instead. The build employs an ESP32 as ...

This project demonstrates a classic embedded system application: using a rotary encoder to control a value displayed on an I2S OLED screen, all driven by an STM32F103C8T6 microcontroller. The entire ...

Abstract: This paper presents a precision capacitive rotary encoder that integrates a shared charge amplifier, and a multi-stage offset calibration scheme. Recently, capacitive encoders have gained ...

Abstract: This article introduces an inexpensive Wiegand-sensor-based rotary encoder that avoids rotating magnets and is suitable for electrical-drive applications. So far, Wiegand-sensor-based ...

If you ever tried to play the arcade version of Arkanoid on an emulator, you may have found the game impossibly hard. And by that I mean impossible. That's because the game was designed to be played ...
