HealthyPi v4 – Unplugged, monitors vital signs using ESP32
https://www.electronics-lab.com/healthypi-v4-unplugged-monitors-vital-signs-using-esp32/
HealthyPi v4 is a wireless, wearable, open source vital signs monitor powered by ESP32. Reliable health monitoring has traditionally required that we tether ourselves to machines capable of recording our vital signs around the clock. Outside of a clinical setting, however, this is rarely practical. We developed HealthyPi v4 in part to address this challenge. […]

Incandescent light bulbs at the nanoscale
https://www.electronics-lab.com/incandescent-light-bulbs-nanoscale/
Using tiny arrays of carbon nanotubes, a team of researchers at Rice University has designed nanoscale incandescent light source that could be tuned to precisely emit at specific wavelength, based on the materials’ configuration. The so-called nanoscale thermal emitters described in a paper titled “Non‐Hermitian Selective Thermal Emitters using Metal–Semiconductor Hybrid Resonators” published in the […]
Window Comparator – Window Detector with relay output
https://www.electronics-lab.com/window-comparator-window-detector-relay-output/
A window detector circuit, also called window comparator circuit or dual edge limit detector circuit is used to determine whether an unknown input is between two precise reference threshold voltages. It employs two comparators to detect over-voltage or under-voltage condition. This circuit utilizes two comparators in parallel to determine if a signal is between two […]
