Do you feel like you’re being stalked by the number 555? Are you seeing it on clocks or addresses or license plates? Your coffee order always $5.55? If you’re freaking out, do not worry—I am here to ...

Abstract: Defect detection is an essential requirement for quality control in the production of printed circuit boards (PCBs) manufacturing. The traditional defect detection methods have various ...

Abstract: The most compelling and simplest chaotic circuits have always been technical challenges. Here we report an inductor-less 555 timer chaotic circuit, combined with two resistors and two ...

For decades, I’ve had a fascination with voltage-to-frequency converters and the 555 analog timer chip, and therefore a double obsession with VFCs based on the 555. In fact, my first Design Ideas (DI) ...
