The ESP32 controls the fan's speed using the TIP120 transistor, while the external power supply ensures the fan has sufficient current to operate.The ESP32 is powered from 7805 IC . 7805 IC step down ...
Researchers at the University of California- Santa Barbara have devised a new framework that could contribute to this quest, enabling the fabrication of scalable three-dimensional (3D) field-effect ...
Not only do they spit out test and measurement tools at an impressive pace, but they also try to innovate in the looks department. The first Fnirsi tool that landed on my desk in 2025 is the LCR-P1 ...
