Learn how to create a simple gear indicator for the manual transmission of the car. For that, we will use Arduino UNO with SSD1306 128x64px IIC OLED screen and 4 Hall Sensors to measure the magnetic ...

Adjustable gain to avoid ADC saturation. Supports 120 VAC or 240 VAC (or any value below that). Manual calibration for custom adjustments. Power supply range: 3.3v - 5v ...

Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...

Abstract: A vibration readout of a resonant structure based on inverse magnetostriction with an integrated Hall sensor is proposed. A bi-material FeGa/Si cantilever is fabricated using ...

Abstract: As a novel form of higher-order topological states, the emergence of disclination states has recently attracted considerable attention. However, those states typically involve the breaking ...

FULL METAL JACKET: In a striking escalation of federal presence in Illinois, the Department of Homeland Security has set in motion a plan to deploy 100 National Guard troops to the state, a move Gov.
