“just another keypad 21 mechanical keys configured as a numerical keypad plus 4 programmable macro keys. Another write-up can be found at clews.pro. The main features of this keypad include: - HID compliant USB peripheral using an ATmega32U4 microcontroller with …

LED Running Lights

“In todays article, I will show you running lights based on three popular microcircuits: an operational amplifier microcircuit LM358, a timer microcircuit NE555, and decimal counter microcircuit CD4017. The running lights schematic diagram and printed circuit board (PCB) were developed …

Less nosy smart speakers

“Technology could capture household information without recording speech. Microphones are perhaps the most common electronic sensor in the world, with an estimated 320 million listening for our commands in the world’s smart speakers. The trouble, of course, is that …

Lighting Up Ultrafast Magnetism in a Metal Oxide

“Understanding how magnetic correlations change over very short timescales could be harnessed to control magnetism for applications including data storage and superconductivity What happens when very short pulses of laser light strike a magnetic material? A large international collaboration led …

Long term dust monitoring using GP2Y1014AU0F and Blynk

“Monitor the surrounding dust and large particle (>0.5µm) for long time using Blynk IOT and plot the data for further research. In this project I have made a IOT based Dust density monitor which can measure the surrounding dust …

Low power ESP8266 sensor data logger

“This tutorial demonstrates how to make an ultra low power sensor data logger running on 2 AA batteries for more than a year. Recently I tried to make a data logger using ESP8266, to periodically upload temperature/humidity/moisture measurements …

Magnetism Drives Metals to Insulators in New Experiment

“Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying heat and electricity. While gold is a good conductor under any conditions, some materials have the property of behaving like metal conductors only if temperatures are …

Mars helicopter Ingenuity aces 7th flight on the Red Planet

“NASA’s Mars helicopter Ingenuity now has seven Red Planet flights under its belt. The 4-lb. (1.8 kilograms) chopper took to the Martian skies again on Tuesday (June 8), making its first sortie since battling through an in-flight anomaly …
