In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...
Abstract: The article reports for the first time a distributed electrostatic-driven T-shaped micro-electromechanical system (MEMS) resonant accelerometer based on the modal coupling phenomenon.
There’s a well-known movie trope in which a hacker takes control of the traffic lights in a city, causing general mayhem or ...
Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...
Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...
Abstract: This paper investigates the dynamic characteristics of the mode-localized resonant accelerometer (ML-RXL) both in small-signal and large-signal models. The analytical model of ML-RXL ...
